SWL & HAM Bio
Thanks for reading this information and taking interest to find out a little about myself and my hobbies. My name is Rüdiger (Rudi). As a young boy, I developed an interest in electronics through an friend of mine at the age of 11, and obtained my first detector receiver. And later on, I got started in radio (SWL) as a root of my hobby, by listening to the AM broadcast bands back in the 1970s. 

My interest for Ham-Radio (HAM) started when I was 16 years old. By the age of 17 in 1966 I acquired my shortwave radio listening (SWL) license by DARC. I was proud using a BC-348 military receiver in the 70s which I had got from a licensed friend. At an age of 23 I received my C Class license for VHF/UHF and higher frequencies and a few years later I acquired my CW Extra A Class, full licence. 


Biography
I live downtown in the city of Düsseldorf (JO31je) 40 m meters above sea-level, which is located east of the border of Netherland and Belgium on Germany's largest river Rhine in North Rhine-Westphalia. My Amateur hobby and Toolmaker apprenticeship led me to the University of Wuppertal, Germany followed to an engineeing career in electronics.


Düsseldorf
A remark on Düsseldorf. As mentioned, I am living in the city of Düsseldorf
, which I call it "the largest village in Germany". The translation disclosing why: (Düssel = Düssel is the name of our small city river and dorf = village). It's a beautiful international university city to life, which is surrounded by a village river character, without skyscrapers but lots of trees.

.
Lifestyle   „Don’t worry, be happy“
Now, I`m 68 years young and retired ham, sitting in my rocking chair and being happy, watching WSPR, enjoying HAM-Radio. To get moved, I’m active as photographer making nature and macro photos at home and on-site as well.
 

Visitor Highlights in our Garden
When I am not sitting in my rocking chair, perhaps I am sitting in our very quiet backyard garden in Düsseldorf, watching not only lovely chirping and warning birdies as one can see.

My Recent HAM Activities
                                               To be radioactive is a way to keep the doctor away!
Mainly digi modes


Activities
My favorite frequencies are from 10m up to 70cm. I'm also QRV on shortwave using my own remote base station IC-7400, which I am sharing to friends through RemoteHams (topic 5/6/7). I also enjoy and are predominantly QRV in digi mode like: weak signal·communications.



Welcome to the land of whispers. Currently WSPR (Weak Signal Propagation Reporter) has become my favorite mode. It is absolutely fazinating to see the distances which are possible with low power signals. The core software was written by Joe Taylor K1JT, who happens to be a Nobel Prize winner.


WSPR TXing Distance Test on 20m with 2 Watt on my 42m Long-wire
I use WSPR beacons as an automatically running test tool for comparing various antennas, propagation studdy,
locations, band spot openings when I am not in the shack and antenna performances in general
.

Below is my QRSS (CW) reception report by waterfall screenshot. Joe, VO1NA was transmitting on 137.777 kHz with 500W into his huge and impressive antenna farm!




Tip: QRSS LF / MF Grabbers of DF2JP Are Here Online. 
Tip: This 2nd visual QRSS (CW) reception example is recorded by Joe, DF2JP using a Large Aperture Loop Antenna ALA100LN, which is showing a better results as my Long-wire in this 2200m band comparison.

 
A dot duration = 90 sec. 

 

Devices Which I Used:
Hardware: IC-7400 was
connected to a soundcard of a WIN PC. The Rx frequency was stand-by on 136.000 kHz in USB mode.  
                   Antenna connected was a 42m End-Feeded wire, which is not matched on LF/MF to the RX input.
Software: 
Argo is a program to visually show QRSS, DFCW and other slow digital signals, into an easily configurable waterfall,
                 taking its input from the PC sound card. 
Settings:   under Agro/Calibration enter under frequency 136.000 and set the vertical movable Hz slider (right hand side) 
                in the middle of the Agro-waterfall to 137.777. Then QRSS can be demodulated with the RX frequency set to
                136 MHz with 1,8 MHz IF filter to keep strong LF adjacent channel signals rejected.   

Tip and General Informations: O
n LF usually I keep WSPR-2, WSPR-15 and QRSS software running simultaneously on the tuned frequency 136 kHz in parallel, on the same PC and TRX. Further information's: QRSS Grabber compendium. Loop for 136 kHz.


The Message of Above Infomation's is Clear    Make More Miles, With Digi Modes
I want to say: if you want to work DX on LF, it is possible with a simple Long-wire located downtown in a large city having a lot of urban noise.  Details of my antenna in use, can be looked up on drawing of topic 4!

73's, see you in the pile up!

I Am Akctive in WSPR on Following Bands.
My IC-7400 transceiver running fully automatically with predominantly RX or TX Bandhopping mode exclusively on a Long-wire using the IC-AH4 during daytime.
----------------------------------------------------------------------------------------------------------------------------------------------------
RXing: 2200M, 630M, 160M, 80M, 60M, 40M, 30M, 20M, 17M, 15M, 12M, 10M, 6M, 2M; (active on 14 bands)
TXing: (2 Watt) 630M, 160M, 80M, 60M, 40M, 30M, 20M, 17M, 15M, 12M, 10M, 6M, 2M; (active on 13 bands)
----------------------------------------------------------------------------------------------------------------------------------------------------

Tip for SWL's:  With SDRplay and SDRuno, I can receive WSPR mode from 136 kHz up to 23 cm  (covering 17 HAM bands)

Mostly nighttime band 630m. To transmit on MF is another headache. It is no longer the men-made-noise level in the city, but the antenna length and height over gound as well as the efficiency of the matching network (loading coil - variometer) and of course, the earth conditions which is getting then the most important of all.

Tip: In order to get a decent TX signal and a lot of fun; here is a nice article which explains simply, how to get active on MF in six practical steps: How-to-build-a-630m-antenna: http://www.f6ciu.com/630m/630vk2/630vk.html. Details how I matched my HF antenna to MF can be seen in the schematic diagramm on topic4. 

Tip: Typical digital modes used today are: WSPR, WSPR-15 (LF only), CW, QRSS, DFCW, FSKCW, JT9, Hellschreiber (standard and slow MFSK), JT9, JT65, PI4, Opera, ISCAT and the new mode FT8. WSJT-X Version 1.8 offers nine different protocols or modes: FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, WSPR, and Echo


Hope you catch me on WSPR sometime!

Topic 2
My Macro Stands Studio Concept                                   You see more and know more with super macros
Here are samples of my self-made multi-functional macro desktop stands, applying mostly standard devices, practically combined in a unique and pro way.

 
Horizontal Multi-Functional Focus Stacking Macro Stand
Tip: "Come Closer"  - Take a closer look.

The art of macro photography is infinite with the right tools –> going beyond the limits.

Performing by special technology extend depth of field composed images with an optical magnification of up to 20x, getting ultra-high resolutions images by aid of "Helicon Focus Software" applying focus stucking technology!

Macro Stands: As you can see below, I made several macro stands for different applications to create high magnified and focus stacked images, which afterwards are rendered by aid of a special software to create also unique 3D images like the last coin section sample below showing or creating 3D Videos of the stacked images as well.

Focus Stacking Software: The focus stacking software is a tool allowing to achieve images with theoretically unlimited depth of field. It means that if you have a number of partially focused photos, or a stack, the program will render it into a fully focused image by combining the sharpest areas from each photo of the stack.

Macro Stand + Image Sample: The macro stand below showing the quantity of extension tubes required to perform a 10:1 optical magnification images with the EF-60 Canon macro lens. The image that I made of a hornets head (Hornissen-Kopf) shown on the bottom left hand side was made with 4:1 optical magnification (4x optically enlarged, plus your screen enlargement).

MY FOTOGRAPHIC SUPREME DISCIPLINE   –   Super Macro of a Copper Coin Section

What’s about the image below?
You can see below a simple coin or specimen device holder which can be integrate into my multi-functional horizontal stucking stand (1st macro image above).

Furthermore, as one can clearly see, in the center of the complex created image a star. This star image was made by aid of macro lenses and stucking technology mentioned above. It is one out of six stars which are located on every 2-cent euro coin. The stars size are only 1mm in a diameter in its original size!

What is superb in the image?    
You can see high resolution details of a manufacturing embossing process, showing the very huge enlarged star. By a macro stucking rail process, I have combined 200 pieces of high magnified single images, which are processed with aid of photo stucking software like "Helicon Focus".

Have you seen the magic details?  
If you take a closer look to the center of that high magnified and high resolution image below,
you may see:
    -  A machine made embossed star in a real 3D effect.
    -  
A raised 3D effect at the image corners as well.
In addition, one can also see, especially for analytical purposes and that's the target for such images, 
the abrasiveness (roughness) structured surface caused by embossing work!


What can we learn from it?
Advanced analysis and quality control feedback information's of the ongoing manufacturing process: 
Quality results and consequences.
The more the coin surface roughness and less corner sharpness becomes an issue during machine made process, the more worn is the mold forming tool to be renewed or consequently be
replaced.


Screen enlargement
Tip: If e.g. the star reaching 90 mm in size on your screen surface, 
that makes a 90x
enlargements of the 1mm star in its original size on the coin.

Wide-angle super close-up overall macro photo is extremely difficult to take, unless the light is overcast
and a special high-magnification relay lens setup applied covering macro up to infinity (DOF) range.


The easiest way is to use a compact camera that has a "1cm" marcro mode with suffient magnification. ​Another way is
to use 
a wide-angle lens on a very short extension tube, for instance use a Nikkor AI-s 20/3,5 on the old K1 5,5mm ring.

 
In the middle of nowhere? No, it's only a 15 minutes walk from here, in the middle of the botanical garden of the University of Düsseldorf.

Image Resolution:
Tip: All images on this page had to be resized down to a size of 800x800. Consequently, the image
resolution quality of my here published images cannot be by fare as high as my original images are.


 

Finally, A Helpful Marco Image Contribution for HAMs    Critical Corrosion Development

Troubleshooting Tip:
A very interesting macro photo for radio amateurs to see. It shows a power supply fuse head showing an extended corrosion progress, which has taken place over many years causing my radio creeping and from time to time abnormal voltage and power drops problems.
The fuse was not blown up!


One can say: An undetected strongly corroded (gradually resistance-incresing) fuse can become a danger for ham device!

SDRplay RSP1 VLF to 2000 MHz Wideband all Mode SDR Receiver requires a PC
The SDRplay is a powerful recent generation of economical (well priced) wideband full-featured Software Defined Receiver (SDR) which has an exceptionally wide frequency range​ and covers all frequencies from 8 kHz up to 2 GHz (without gap). It has 12 bit A/D conversion. Great selectivity​ and super high sensitivity (!) with a low noise floor including variable IF bandwidth. In order to use the SDRplay as a panadapter, it has up to 10 MHz of spectrum which can be monitored at a time!

The front end is protected by a series of automatically selected passive RF filters and 2x2 antiparallel overload front end protection PIN diodes. Advantage: My SDRplay is connected to a MiniWhip, which is only placed at a distance of 6m to my Long-wire, which is connected to a 100W HF transceiver, which causing no overload on the MiniWhip as well as on the SDRplay! See also drawing details in topic 4.

Tip - SDRuno Software
I am using the specially for the SDRplay designed superb SDRuno Software v 1,11.

Multiple ‘Virtual Receivers’ which allow for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth.


Tip - Real time comparative testing using WSPR.  I use the SDRplay as referance device to compare antennas. Two receivers receiving simultaneously, one exciting a 'reference' antenna and another a test antenna by comparing the differential spotted results of sending stations.

Tip - Signal Indentification guide for digital modes is here. SDRplay and my antenna wiring details at my shack can be seen on the schematic drawing (topic 4 and 7) below). SDRplay schematic diagram is here.

 

Atlas 215X HF SSB/CW mode transceiver
My vintage mobile transceiver from the 70's, is already completely equipped with transistors!
I use it for decoration only, sometimes used for special events and monitoring purposes.


My End-Fed Wire as Inverted-L Random Wire Antenna    HF ANT 1
For 160-6 mtrs I am applying a IC-AH4 tuner with a 42m Long-wire connected, which is oriented in east-west direction.
My wire is a simple random-length wire suspended from trees in a similar inverted-L configuration
. The vertical section has a strong infuence of the radiation, while the horizontal section provides capacitive top loading features. The performance of an inverted-L antenna system on HF relies heavily on the ground system.

Tip1: I assume, the same is true for 630 meter operation - likely the grounding system will be even more important at lower frequencies like VF/MF due to the relative "shorteness of the antenna. Losses in the ground system become a great percentage of the antenna resistance as the length is shortened, decreasing the overall efficiency. 
Tip2: As I do not want to enhance our ground system (garden) with added radials and rods. My ANT 1 is t
herefore working against a huge counterpoise, which exist of a copper pipe heating network of a large 11 flat Building. In addition for low band operation, I can use by a switch also the water pipe system. The coaxial cable of my roof ANT 2 (45m) acts  accidental as a radial to some degree as well.
Tip3: As my antenna is used for low bands as well and as it is located in the city, I have to live with a high noise foor. Due to "electronic pollution" I use the antenna at low bands preferably with digi mode and in difficult cases more and more in WSPR TXing mode.
Tip4: NEW, to use my Long-wire for MF TXing.  I want to avoid, that my 630m RF transmit power output (TPO) gets burned up in ground loss and dissipative ohmic conductor losses. I have upgraded the matching system for 630m band (see photo "test arrangement" under topic 4). Instead of  IC-AH4, I am using for 630 m band a loading coil (325 uH) inserted in series with a variometer (40 uH - 175 uH tuning unit) conected also in series to the Long-wire, which is more or less an inverted-L antenna 16m/36m . To match this on MW resonant ANT 1 to 50 Ohm I use for impedance matching an toroid core FT-140-43 using coil with taps (impedance steps). In addition, I have improved the counterpoise grounding system, by connecting the water pipe buried under ground in the garden by wire to the copper pipe heating network, which I have well experianced as good running couterpoise for HF already 
 
The drawing under topic 4 and 7 showing the wiring configurations.



Vertical HF/VHF/UHF ANT 2
-  For 20-6 mtrs alternatively I am using the 6m section of a vertical Diamond V-2000 antenna (matched by coax tuner).
   On 10m it is nearly a 1/4 vertical
polarized pin, with an efficiency like a good working mobile antenna. 
   As it is mounted on top of a high roof, it has a very low
urban noise floor compared to Ant1.
   Topic 4 and 7 below showing the wiring configuration. This antenna is also used for VHF/UHF.



MiniWhip E-Field-Probe ANT 3 (RX)
This antenna is mainly the design of the PA0RDT-Mini-Whip ©, (8 KHz to 30 MHz). See WSPR information at this link and at WSPR under Topic 8/9 at the final end of this page. For WSPR on 2.200 Meter and 630 Meter (8 kHz to 474 kHz) I use preferably the high performance of the MiniWhip antenna, hunged up in a small tree, 3m above ground.

For VLF/LF/MF/HF my home-brew MiniWhip reference antenna (IP3> +30dBm) receiving mainly Electrical fields. It can excellently be used for QRM illuminator and diversity purposes. In addition, it works excellent on my SDRplay receiver using SDRuno and WSPR-X software together. On 40 Mtr. e.g. the spots with the MiniWhip compared to my Long-wire are on the same level.

Tip: Note that the height of the antenna above ground makes a difference to the output signal level, but once you get outside the local noise field it does not make much further difference to the S/N  ratio.

It is a prefered solution to put the antenna up in a tree (>3m) and as far away from houses (>10m) as possible, run the coax down the tree to the chock and earth spike at the base of the tree and then run the rest of the coax back  to the shack either along the ground, or better still buried a few inches below the soil.
 

  I can transmit with the IC-7400 with 100W SSB or in WSPR (2W) on the Ant 1, which is located in 3 m distance to the MiniWhip (see topic 4 drawing below). Whereby, decoding my WSPR TX signal parallel in real time on the SDRplay running WSPR RX mode using the MiniWhip active antenna having no overload problems

My Long-wire Backyard Antenna is Invisible and Suspended in Azimuth Direction 100 Degree
Tip: In summer time e.g. at a distance of 2 m from the wire, one cannot see the wire of the antenna at all. 
What does it mean: If 11 flat owner do not see the antenna, during garden inspection, they do not care about it!
Never give up, there is always a way...

Tip: How to improve a vertical antenna by inductive toploading for low bands are explained here: In an environement with a lot of 'vertical objects' (trees etc.) close to the antenna inductive toploading (horizonal part) can significantly increase the performance of a short vertical antenna. 

A top hat is necessary to get a desirable current distribution and as high a radiation resistance as possible. Additionally, the top hat adds a lot of capacitance to the antenna, reducing the inductance of the loading coil needed to resonate it and reducing the losses associated with the loading coil (this information was published by: Robert Bicking, W9RB) .

An Excellent Project(s) Made by DJ0ABR  U02 DDS etc.

Advanced Multimode DDS Synthesizer   Autonomous Multiband WSPR Beacon Exciter
Tip: RF Sweep-Generator 0,1-160 MHz covering 15 HAM bands having multi functions. This extendable kit project can discover and revitalised the interest in our 'hobby' again and invite to issue a lot of electronic, RX/TX and antenna experiment ideas!

Antenna testing using WSPR. Since this outstanding WSPRing mode blocks the HF TRX, Kurt (DJ0ABR) has developed a DDS, in which one can participate without great effort in this fantastic operating mode. Internet is not required for this because time synchronization works via a GPS mouse.

Since recently, I am owner of this fabulous multi purpose exciter tool. My new ultra compact WSPR, CW, D-Star, FM, AM, Synthesizer and Sweep Frequency Signal Generator 100kHz up to 160MHz is made by DJ0ABR is working successfully. This assembled unit works on 15 bands completely PC independent and can be configured either with a PC software (Windows, Linux or Mac) or via Bluetoooth with an Android Smartphone. It includes a sweep generator for antenna and filter measurements and an incremental power control for the PA.

This device makes use of the capabilities of a modern DDS Synthesizer (direct digital synthesis Method) to create a autonome standalone WSPR beacon with Bandhopping mode and a complete powerful Signal generator capable of various modulation and test modes. It is an open Source and free for use by Amateur Radio Operators. The DEU/ENG homepage Link of the author DJ0ABR is here and his shop named Helitron is here

An optional 5 watt QRP PA for the frequency range from 400kHz to 54 MHz in 11 HAM bands is available as kit and high pwr PA versions as well. I will use it for overnight WSPR TXing operation as a simple setup without pc, mainly on low bands matched trough loading coil etc. and for the HF bands a 1:9 balun will be tested comparing to automatic tuner in bandhopping mode.

HAM RADIO DXing
Public Remote 
 

 Remote Controlled Internet Based Amateur Radio Stations 
 
In the case that an internet is available, you can access to control and operate my or other ham radio stations remotely from anywhere or optimize propargation by monitoring your own station on the other end. Just a WINDOWS pc / tablet or ANDROID smartphone / tablet and a low cost headset will do!

Tip: On client Internet user side you require only a PC, Tablet or Smartphone and RCForb software to a access my transceiver IC-7400 and perhaps other online remote stations as well.

In other words, overcome local stations restrictions or limited station capability. If all that is interesting for you, than follow the information and tips with further amount of interesting features below.

Please be informed, you have to be a registered user of the "RemoteHams" community. Therefore, visit here 
to create your free account.

You can enjoy operating remote amateur transceivers & more by joining the remotehams community. Don't miss rare DX you may never have a chance to hear. Test your own signal propagation, are you being heard in a DX location.

Furthermore, it can be a good occasion to use a remote, especially if you do not have a:
    - suitable antenna permission
    - locally high noise level, interference
    - or you are on a business or vacation trip

    - discover generosity remote operations
Advantage: A transport of transceiver, antenna and installation is not required at all!


What you need is the RCForb (Client) software for Windows SYS or an Android handy / Tablet App). It is an application you install on your computer for using all the online remotes.

You can use it for RX only or for TX and more! The client software also has a new built-in VOIP feature allowing users to easily RX and/or TX on remotes using a single application.

Guest, SWLers and DX Listeners are Welcome 
Guests logged in with an account at RemoteHams have free access to the receiver functions of the transceiver, without transmitting function of course, like a listen only membership.

I hope it will helps to recruit more newcomer to the hobby. ABC’s of getting a Ham radio license one can find here.

Tip: An informative great video about Amateur Radio is here,  "Amateur Radio a hobby for the 21st century" [ Great Video ]. Information in German language, search under Google for this PDF: BehelfAmateurfunkV8.pdf.


Amateur Radio Operators 
Licensed / legitimated amateur radio operators as a new remote user can get familiarized by starting to test the remote functions without having TX permission requested. It is also useful to check signal propagation without being registered. I hope it will help to recruit more hams coming up also with an own remote as well! 
Tips for hams intented setting up a remote based station should have a look at topic 7.

If no one else is logged in to this radio you may tune / change the frequency or perhaps transmit "TX" without asking in advance.  


Identification operating through a remote is required! 
You have to announce, that you are transmitting through a remote station located in Germany!
It is independent from your physical present location. 


If you are a foreign operator (TX Users) on my remote, you must identify yourself independently from voice and or digital QSOs as follows: 

For example:   cq cq cq de dl / your callsign 
​                                 
qrz de dl / your callsign


As my remote is located in Germany, do not forget to add:

Receiving Ranges “RX”
Usable bands: VLF / LF / MF / HF and VHF. All amateur bands from 2200m to 2m

The  receiver  (RX) covering in total 14 ham bands and
the transmitter (TX) covering in total 11 ham bands.


The receiver frequency ranges: 
0,03 -  60 MHz - Info:  The Citizen Band (27 MHz) and sometimes also outside HAM band sections have been blocked on this remote
144 - 146 MHz - Tip:  Try the SCAN knob. To resume scan push 2x scan button.


Tip 1:
If you are interested in other frequency ranges, you may find
here and here some interesting remote receiver links.


TIP 2: 
All Mode Web-SDR Twente Receiver

University of Twente, Enschede in the Netherlands. On the page of that listed link below you can listen to and control a short-wave receiver located at the amateur radio club ETGD at the University of Twente. In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio, see link here and here.

TIP 3:

WSPR Mode Integrated in the Wide-Band WebSDR located in Twente
Continuously monitor the WSPR frequencies in all amateur bands below 29 MHz http://websdr.ewi.utwente.nl:8901/wspr/


TIP 4: Online SDR in the UK, see link here. This HF WebSdr is located at the Nantwich Secret Nuclear Bunker, formerly R.A.F. Hack Green, now a working museum.



Mode Available on My Remote
LSB, USB, CW, FM and AM mode can be selected and executed.

 Mode selecting window

Please check during a band change, if also a "Mode" change from e.g. LSB to USB 
(10 MHz to 14 MHz) manually is necessary.


Repeater Shift and Split Mode.
It happened several times, that users wanted to operate in SSB mode and did not noticed that a shift is still running. Therefore, FM repeater shift or split mode is only on request for a session available.


IF-Filter Bandwidth
You can select the "Filter" bandwidth “Wide”, “Medium” and  “Narrow” separately for each mode.

 Medium is recommended
(e.g. 2.4 KHz for SSB)


Generally start to use the medium filter. If you receive a strong signal and there is no QRM, that you toggle to filter wide. If there is QRM from the adjacent frequency, than use the narrow filter. 
 
                           Wide              Medium            Narrow
                                                
(recommended)
SSB:                 3.6 kHz             2.4 kHz           1,8 kHz
CW:                  1.6 KHz             0.9 kHz           400 Hz
FM/AM:           15.0 kHz           10.0 kHz           7.0 kHz



CW RX
Tip: If you want to receive CW and digital signals in SSB mode, be sure that the auto notch filter "ANF" is switched off. In "CW" mode the notch filter is switched off automatically. CW TX mode is due to

Tip for CW Freaks: Following IF kHz section combinations can be used for cw reception:
3.600 LSB,  2.400 LSB,  1.800 LSB,  1.600 CW,  0.900 CW,  0.400 CW.



CW TX Simple Made
Tip: You can operate CW via Keyboard on my remote.
A simple way enabling CW TX mode is to use LSB mode on (any) remote station.
Just use MixWin3 / HRD etc. in CW mode and generate CW TX audio side-tone signals with the pc keyboard, that's all.

The CW enthusiast of course preferring a normal paddle against a keyboard.
Note: CW TX direct mode with a paddle is due to difficulties (extra comp port) not yet possible?



Digital Mode via Remotehams and Its Power Settings
Use always "USB" mode to apply following digi modes SSTV / PSK31 / RTTY and
WSJT-X (WSPR). 


Note: To protect the transmitter at digital modes, the transmit power must be reduced to less than 30% of the maximum adjustable output power of 100 %!

Therefore, check on the drop down, named "TX Mtr" that the TX power is below 30 % = 30 Watt.

Since recently I am controling the TX pwr locally. Remotely not possible anymore.

 Example Copy: SSTV ISS

As mentioned above, avoid audio clipping and TX overloading.
Please remember to reduce your internet to be transmitted audio in order to reduce the power output of the radio down to say 30 watts or less, as most Digi modes are 100% duty cycle modes.

Tips from DM5SR. Stephan located nr Koblenz Germany has published details how to apply digi mode tested with several popular software programs via RemoteHams.
​M
GM - Digi mode software download collection listed here.

As foreign operators​ (TX User), do not forget to add: DL/ in front of your callsign on my remote.
Digi mode copy sample from WSJT-X user guide (JT65) made by K1JT:

CQ DL/K1ABC FK68
                                  K1ABC G0XYZ IO91
G0XYZ K1ABC –19
                                  K1ABC G0XYZ R–22
G0XYZ K1ABC RRR
                                  K1ABC G0XYZ 73

 

Meteor Scatter Mode (MS)
When calling CQ with FSK441A (WSJT) on 144.370 MHz most amateurs have adopted the method of sending 'CQ 385' which indicates they are calling split by transmitting on 144.370 MHz BUT listening on 144.385 MHz for replies, this avoids congestion. When the original station hears your reply on 144.385 MHz they then QSY to 144.385 MHz and both stations complete the QSO on 144.385. They do not work split after the CQ is answered. On 6m MS frequency is 50.370 MHz.


Tip: RX Preselection “Tune”
The used tuners are operating during receiving as frond end RX filter. This requires, that after a band change, it is always recommended to press "Tune" button, in order to get the antenna tuner also moved to the new dialed band, keeping the Rx sensitivity constant high!

 Tune Button


Tip: The S-meter and speaker audio will react if a signal strength increase will take place (typically 2-4 steps) on HF bands after "Tune" button been pushed (Works only for TX permitted (X) and (A)Users).
  


According to IARU Region 1 Permitted Transmit Frequencies.
Applied TX frequency activities are permitted only corresponding to your personal valid Amateur Radio license and license class of course and the German Ham band segments and regulations as well.

Contest Operation
This remote is not a Contest Station. It has not continues operation performance!
Therefore do not use the IC-7400 for permanent contest operations.
I don’t mind, if some distance test rapports will be issued!
As foreign operators, do not forget to add: DL/ in front of your callsign on my remote!



Antenna Matching “Tune” for TXing
Tip: After a new frequency been dialed / tuned please push always "Tune" button before transmitting. Make sure antenna has a low SWR (access by "Tx Mtr" command - see image below).



Meter Indication Selection (TX Mtr)
Simply  toggle between "ALC", "SWR", "PWR" and "Comp" (compressor) meter to countercheck all parameters.


   Selectable meter indications


PTT.
"TX" with CTRL+T possible or use the marked “TX” (PTT) button.



"Test" Button     Voice Chatting Mode  –  Intercom
Tip: This mode is like a conference mode without RF transmitting. When this button is active, the radio will not be keyed up, but the VoIP will be rerouted so (X) Users may make a conversation without keying the transmitter (PTT).

 
"xxx" Buttons


“Lock” Button – Android Sys
Tip: If you want to start to transmit with the android system, I recommend to use the frequency “lock” button function first!

Before you are goin to disconnect, please cancel the lock function, to avoid that other users cannot control the remote as it is locked.



“Mon” Button.
This function enables, that you can monitor (listen) to all transmitted audio conversations of logged in (X) User who are transmitting. The function cannot been toggled off! 



Tuners in Use on my Remote
ANT 1 is running with the external Long-wire automatic antenna tuner ICOM IC-AH4 and
ANT 2 is running with the internal automatic coax antenna tuner of the transceiver.



Remotable HF Antenna Switch.
The IC-7400 transceiver has an internal antenna switch to toggle between:
Antenna One”  ANT 1 horizontal 52m  long-wire (80m-6m) and
Antenna Two”  ANT 2 vertical 2,5m VHF antenna (RX: 20-2m) and (RX/TX: 10-2m).  




HF "Antenna 1"
It is a 52 m long-wire End-fed antenna which is connected always with an automatic long-wire tuner model IC-AH4 (160m - 6m). It is my best preforming antenna for all HF bands (RX and TX mode)! 

Internal Pre-Amps:
No need to use on bands 160m-30m any pre-amp it has no advantage. On the other hand, the RX will not be overload, as it has a high RX diynamic range.



HF/VHF "Antenna 2"
A vertical mounted V-2000 Diamond antenna is connected to the internal coax tuner which can be used alternatively for the bands 20m-6m. The main advantage can be, a strongly reduced urban noise floor during RX mode. However, the internal "pre-amp 2" is always required!

Advantages to Apply "ANT 2" for the Upper HF Bands:
- On 10m e.g. it is nearly a 1/4-wavelength as vertical pin.
- During band opening, DXing can be possible.
- Due to the internal coax tuner unused on the high on a roof mounted antenna 2, the antenna
  efficiency with that small vertical roof antenna is likewise a good vertical mobile pin, having
  strongly reduced noise level, compared to my long-wire mounted through the trees
in a backyard!

You can compare the antenna 1 and 2  simply by remote control.
For example, listen to a station on 21 MHz and toggle "Antenna 1" and "Antenna 2" on the remote, whereby the tuner every time been pushed before listening with the selected antenna. Whereby the pre-amp must be selected.

My Experience: I apply the 6m section of this VHF antenna 2 regularly in RX SSB mode on 20 m and upper HF bands, having an ultra-low urban man made noise floor with a signal-to-noise (S/N) increase of +10 dB (tested by WSPR) against my 52m long-wire antenna on the 20m band!

Please Note: the TX
reachable distance performance on 20m to15m of antenna 2 is not that good as ANT1.
But during receiving (RX) the reachable distance
on 20m to10m can be better, because ANT2 is mounted high on a roof having therefore a significantly less noise floor and a omnidirectional function!


VHF Antenna.
For 6m the “ANT 1” (horiz.) or “ANT 2” (vert.) can be used.
For 2m the “ANT 2” is automatically selected. Use always with antenna 2 the pre-amp2.

Frequency Dialing Flexibilities:

Tips for Manual Keyboard VFO Scanning / Tuning.

CTRL RIGHT/LEFT =           0.1K Steps.
CTRL UP/DOWN =               1.0K Steps.

CTRL SHIFT RIGHT/LEFT = 10K Steps.



VHF Memory Scanning “Scan”.
The IC-7400 memory bank (100 FM memories) will be automatically scanned, when the "Scan" button is pushed. To resume push “Scan” button again 2x.


 FM Memory Scan


Automatically VHF activity and DXing Searching “Scan”.
If the memory scanner stops at an SSB frequency on 12m, 10m, 6m or 2m in “FM” mode,
then quickly switch to USB mode, it might be good DX conditions on the upper HF or VHF bands!



Convenient Frequency Tuning by Mouse Wheel Spinning.
Elegant solution: Set the mouse pointer over the VFO knob "tuning knob" and select next to it your “Steps” and leave the cursor over the “VFO” knob using the mouse wheel to step the frequency either up or down.

 
Mouse wheel pointer position  –  SCROLL THE MOUSE WHEEL

The frequency tuning by mouse wheel is convenient like the handling on a real VFO knob.

Advantage of the preset 500 Hz steps: Since recent years almost all SSB stations can be reached by 500 Hz steps!

Simply open at top right hand side under Windows > "DX Spots" and enter your callsign and select next to it a "dx cluster server" followed by double-click to one of a listed “DX spotted station”.


 
Whereby, the transceiver jumps instantly to that band and frequency! Select manually the correct mode (USB/LSB/CW) by hand.


DXing by Mouse Click Only


DXing with a Remote is Usually Limited
It should be noted, remote stations having reduced transmitting power and using multi-band antennas, among other complexities. A remote do not have the DX-business as an objective. Because, unlimited long distance DX qso will be reached through its Internet feature!



Android Handy / Tablet.
With Android system call up the DX Cluster and press “Connect” and click 2x to a spotted station, there you go. Alternatively a Windows tablet with the standard client software is suitable as well.

Listen With This Remote Station Online to 70cm FM Repeater Located Near Düsseldorf.
My permanent scanning ICOM IC-E91 passes received audio signals from 70cm FM repeaters to the IC-7400 on a special 2m FM cross-band frequency (1mW via dummy load).

When the cross-band frequency 144.019 MHz is tuned with the IC-7400 "VFO" and "FM" "Wide" is selected, then you hear active 70cm repeater signals online in real time on the internet side.


Automatically VHF activity and DX Searching.
If the memory scanner stops at an SSB frequency on 10m, 6m or 2m in “FM” mode, then quickly switch to USB mode, it might be good DX conditions on the VHF bands or a Satelit signal crossing!


Please Use My Memory Bank A.
A)  Remote Memory Bank: This particular cross-band frequency in addition to other stored ch by me, can be conveniently accessed from the remote memory bank in the Windows or Android client software!


Create Your Own Memory Bank B On My Remote. (Tip)
B)  Local Memory Bank: An other feature is, if the "local bank" and "Add" is selected, you can save yourself favorite frequencies with additional features into your own client software! For example: Club and DX-frequencies on various bands.

The purpose of this brief guide is to assist the ham operator who is curious about remote operations, but uncertain whether it will be interesting enough to set up an own remote station and perhaps sharing it to friends as well. 

This information is referring to the remote station of DL4EAI, showing the components requirement appears setting up a remote in a very simple and comfortable way.

My Public Remote Equipment Setup of DL4EAI Consisting of:
   *  ICOM transceiver IC-7400  –  servicing Amateur Radio bands: 160m - 2m
   *  External long-wire automatic tuner  –  IC-AH4  (160m - 6m) for my horizontal antenna

   *  Random wire ANT 1 - in the backyard over 15m altitude is a 52m long-wire hidden in a large tree 
   *  Internal transceiver automatic coax tuner  –  (20m - 6m) for my vertical antenna
   *  Transformer power supply 13,8 V / 35 Ampere, avoids overheating and RF interference

   *  Desk top mike: ICOM IC-SM 6  for the remote station IC-7400
   *  Sufficient counterpoise for ANT 1 (central heating system of 11 flats)
   *  A WINDOWS fully metal covered Exone Notebook server PC without any fan. A good stable internet

   *  HP ZR24w Monitor
   *  Android tablet PC for portable operating and testing completely the remote radio system RCForb App
   *  Apple iPhone & iPad with Puffin browser (!) for instant monitoring the remote (except audio)
  
*  To maintenance my WINOWS server pc and managing the RCForb client software from distance directly,
      "TeamViewer" or RD Client software is running on the WINOWS server PC and tablet as well. 
 

Noise Reduction Device Lingua V6
When I am sitting in front of the remote, I normally use the LINGU device during monitoring the remote.

Description: Recognizing human speech by its characteristic envelope curve, to isolate and extract speech from the noisy signal received, and to feed the extracted speech content to the audio output. This process gives you speech without noise!


IC-7400 HF / VHF all Mode Transceiver
RX: 0,03 MHz - 60 MHz  
RX: 144 MHz - 146 MHz and 438 - 440 MHz (see feature II below).
TX: 160, 80, 40, 30, 20, 18, 15, 12, 10 , 6 and 2 Meter bands.
- W
iring details can be seen in the schematic block drawing below​.

Feature   I: To remote and operate this IC-7400 radio via Internet by myself, it is connected to RemoteHams here.
                  

Feature  II: Guests can tune my remotable IC-7400 also to 144.019 MHz and listen to a Crossband online audio
​                   stream of active 70cm repeaters coming from my permanent scanning FT-8100 / IC-E91 
(see drawing below)
Feature III: Licensed hams may request full station control (perhaps including transmit capability for 80m to 2m) 


Feature IV: Skype livestream from the speaker audio of the online remote station IC-7400 of DL4EAI.
​                    Open & free Skype auto account: search for
dl4eai-1 and listen to the online live remote audio stream.

Rig and Interface
Below you can see my rig which to be connected to any USB Interface. In the photo sample below it is a high performance USB interface used, which has integrated a CAT interface and a soundcard and the possibility for keying CW keying (DTR) on the remote. 


Plug and Play Cable
A fantastic way to configure the radio cabling between the transceiver, interface and computer is super easy. It can be supplied for individual transceiver types as an optional package on request from the interface supplier as well. 
To get an image, how it looks like and how simple it is to set up the wiring, can be seen on the bock diagram below. As one can see below, it is a simple way wiring a remote,
 although the setup will be a bit more complicated than other sound card interfaces.

Access with Special Application Features For The Remote 
Feature A: Monitoring and Remote Controlling the Own Remote Base Station 
withaid of DM780 from HRD
without using the RCForb Client Software and
without being connected to remotehams as well!


Feature B: A further main reason for this mode can also be: if a (X) User is
performing digi mode through your remote, you as remote owner can monitor
through DM780 parallel in the background, without disturbing and sharing the
running QSO. 


For distance remote control (not sitting in front of the own remote station) and 
for monitoring purposes of the outgoing voice and or dig. mode traffic, I am using sometimes:
    + Desktop Remote         
       (between desktop pc and mobile phone)
    + RCForb Remote          
      
(between RCForb server software on the desktop pc and internet to remotehams.com)
    + HRD (DM780) Remote​
      
(between DM780 to TRX to be able to change from my mobile phone freq. mode etc.,
       without beeing connected as client to remotehams).

together in one session on my iPad.
The audio is monitored by Skype or locally by IC-E90
(see above drawing: antenna selction architecture).


Note: HRD is required for this special remote function. Because the RCForb server software does not show any TRX controls nor any dialed frequency of the remote station. And TeamView or RD Server e.g. cannot be used for above desrcibed features. 

From a technical and legal view point one can say:
The owner of a transmitting equipment should always be interested to keep technical and legal problems as small as possible by preventing it.

On the other hand: the more (X) User are active on a remote, the more problems and misuse can occur. From a responsibility view point, monitoring may always be advisable. Below is a screenshot issued with my iPad showing the desk top win pc running

- RCForb server Software.
- Digital Master 780 (HRD)

With the two programs I can remote control from the background the IC-7400 without been direct connected to RCForb client software and I can monitor what frequency and controls are used by the
guests and (X) users on the remote station. In addition, I can remote control the TRX through HRD 780.

Combining Remotehams and WSPR net 
RCForb Server has the ability to set a "Memory" as a "home" frequency. This will make the server return the radio to a favorite spot (memory) after disconnect when no one is connected. At this point the remote owner should be able to leave the WSPR software running "decoding" whatever the radio hears.


WSPR signals are 2-minute long beacons transmitted by many amateurs around the world.

If you need WSPR software to control the radio, you can setup Elecraft K3 emulation in RCForb Server software. I have done this in the past to report PSK propagation.
 

Information to the WSPR digi mode 
you will find at the end of this documentation (WSPR topic 8/9).


 One Night TX WSPR on 40m


Legal matters
Owner of a remote base station should not worry about automatic stations mode,
because remoting is still a controlled operation, it takes an operator!

Topic 8 
WSPR Preface 

Weak signal ham radio communication  -  K1JT

 

WSPR signals are 2-minute long beacons transmitted by many amateurs around the world.


The WSJT project includes five programs designed for amateur radio communication using state of the art digital techniques. Typical applications include meteor scatter, EME ("moonbounce"), and QRP communication at HF. Passed on information's from Joe Taylor K1JT

WSPR
(pronounced "whisper") stands for "Weak Signal Propagation Reporter."  This soundcard program implements transmitting and receiving for a digital soundcard mode usable with extremely week signals. Details at the end of this documentation, alternatively look here. Enter my call sign 2x (for RX / TX reports) under database to see my activity results in details by selectable filter settings.

Interesting DEU link:
http://www.kh-gps.de/wspr_audio.htm


First, a review of some relevant terms and motivations.  It's convenient to think of the various WSJT protocols ("modes") in two groups:

Slow modes
JT4, JT9, JT65, and WSPR.  These modes are designed for communication with extremely weak signals -- often too weak to be heard. Target propagation modes include EME and long-distance troposcatter on HF-and-up bands, and QRP Dxing on the LF, MF, and HF bands. Relevant signal amplitudes are approximately constant over a minute and more, aside from so-called "liberation fading" for EME. Transmit/receive sequences are 1 minute for JT4, JT9, and JT65, and 2 minutes for WSPR.

Fast modes
JTMS, FSK441, ISCAT, and JT6M -- and now also *FSK315* (implemented in WSJT) and *JT9E* through *JT9H* (implemented in WSJT-X. These modes are made for communication with rapidly varying signals: for example, meteor scatter, ionospheric scatter, airplane scatter, and scatter off the International Space Station. The decoders are designed take advantage of short enhancements of signal strength. T/R sequences are 30 seconds (or sometimes even shorter).

Summary Program Descriptions:
WSJT: Modes JTMS, FSK441, ISCAT, JT6M, JT65, JT4, Echo, CW. Optimized for meteor scanner, ionospheric scatter, and EME at VHF/UHF/Microwaves.

WSJT-X: Modes JT65, JT9. Primarily for use at HF.
MAP65: For EME an VHF and higher frequencies. Implements a panoramic, polarization-matching receiver for JT65.

WSPR: Probe potential propagation paths using low-power transmissions.

WSPR-X: Experimental version of WSPR, including the slow mode WSPR-15.

Source code is maintained here SourceForge. For installable end-user packages please go to the WSJT web site at the link below.

WSJT Web Site
 

System Requirements for WSPR:

  • SSB receiver or transceiver and antenna
  • Computer running the Windows, Linux, FreeBSD, or OS X operating system.
  • 1.5 GHz or faster CPU and at least 100 MB of available RAM
  • Monitor with at least 800 x 600 resolution
  • Sound card supported by your operating system and capable of 48 kHz sample rate
  • If you will transmit as well as receive, an interface using a serial port to key
  • your PTT line or a serial cable for CAT control. Linux and FreeBSD versions
  • can also use a parallel port for PTT. Alternatively, you can use VOX control.
  • Audio connection(s) between receiver/transceiver and sound card
  • A means for synchronizing your computer clock to UTC 

    Above list sounds like a lot, but if you’ve ever worked with any digital mode before such as PSK31
    or similar, you probably have all the equipment you need for WSPR operation – it works the same way!

 

Topic 9 
WSPRnet

Here are informations of my 2nd HAM activity which I have posted to the WSPR homepage:

MY WSPR RIG
My ICOM IC -7400 transceiver is remote controlled during band hopping with automatic frequency and band settings on 14 bands, preseted by WSPR through CAT, band sequence and time functions, before
starting RX and TX operations (TX < 3 Watt).

I enjoy the fully RIG controlled and further superb WSPR functions to my IC-7400.
Especially the unique automated band hopping sequences, which are free selectable for all the
2190, 630, 160, 80, 60, 40, 30, 20, 17, 15, 12, 10, 6 and 2 Meter bands for RX operations. 
And for TX the bolded bands operations as well.

In the case, that the transceiver is remotely in stand-by (idle) mode at RemoteHams I often apply manually controlled WSPR RX mode in parallel, to keep the receiver part effectively on working for DXing propagation check, hi.

 

MY HF ANT 1
160-10 Mtrs up to 6 Mtr applying an IC-AH4 automatic tuner to a Random-wire antenna
from dx-wire comp.(endfeeded 42m Long wire antenna) hidden in a tree used for WSPR RX/TX.
For a good ground counterpoise, I use the pipe heating network of a large building.

 

MY HF ANT 2
30-10 Mtrs alternatively to the above mentioned Long wire a 2.5 m long vertical pin
(6m/2m/70cm Diamond V2000) base antenna for WSPR RX in use.

Advantage: With the internal coax tuner I can use ANT 2 for RX and with distance limits
for TX mode on upper HF bands as well.

I apply this VHF antenna irregularly in RX SSB mode on 20 m and
upper HF bands, having an ultra-low urban RX noise floor!

As ANT-2 is on 10 Mtr physically nearly a ¼ vertical pin, I use it during band opening in TX mode
with surprisingly results (>2000km), similar to a high on a roof mounted HF mobile antenna with a
good counterpoise.

 

MY 6m/VHF/UHF ANT
On 6, 2 and 0.70 Mtrs my Diamond V-2000 (above mentioned ANT 2) is used for WSPR and others
modes (like FM and SSB) as its regular design.

On 10 Mtr it is nearly a 1/4 vertical pin. Therefore, with a coax tuner during open band easy DX possible.

This user guideline / user manual is working in progress.

For a quick overview, read at least the red marked text!



Guest and SWL's are welcome.
Guest and SWL's logged in with an account at RemoteHams welcome
having free access to receiver functions of my transceiver,
without transmitting function of course (listen only membership).

I hope it will help to recruit more SWL's to our Hobby. ABC’s of
getting a Ham radio license http://www.hamuniverse.com/study.html

Licensed amateur radio operators as newcomers can get
familiarized by starting to test the remote functions without having
TX permission requested. It is also useful to check signal propagation.


Upload Amateur License Copy
Please upload a copy of your valid license, if you have not already
done so, on the RemoteHams.com page under "My Account".
Once uploading is sufficient. But it is like an obligation!


Getting “TX” privilege.
Simply push once the “TX” transmit button of the remote on the
RCForb client software followed by pushing the “Request” button.

Procedure detail and explanations why TX privilege have to be
limited, see under questions and answers (FAQ). 



Connect and Conversation Formality.
If no one else is logged in ore using this radio, you may tune /
change the frequency (or perhaps transmit – "TX") without asking
in advance.  "TX" mode will be permitted to licensed (X) members only.

In order to avoid, that I will be made responsible for communi-
cations and handling illegally performed with aid of my remote
station, I have to restrict that any conversation to be made
preferably in German or English language on my remote.    

Imported: Foreign operators identify as DL4/Callsign.

Identification sample: cq dl/callsign
Keep voice an Digi QSOs legally on a remote.
Foreign operators, (X) Users must identify as DL/CALLSIGN.
Therefore, do not forget to add: DL/ in front of your callsign on my remote.

Radio Receiving Ranges “RX”.
Usable Bands: VLF / LF / MF / HF and VHF.

The receiver covering the frequency range
0.03 - 60 MHz and
144 - 146 MHz.
Note: The Citizen Band is blocked.
In that case, feel free to test remote receiver:
http://www.globaltuners.com/receiver/


“Lock” Button – Android Sys
If you want to start to transmit with the android system,
I recommend to use the “lock” button function!
https://play.google.com/store/apps/details?id=com.remotehams.rcforb.client


Operating Modes.
The mode “LSB”, “USB”, “CW”, “FM” and “AM” can be selected
and executed as well.

Please check during a band change, if also a "Mode" change
(e.g. LSB to USB  –  10 MHz to 14 MHz and back) is necessary.


Repeater Shift and Split Mode. 
It happened several times, that users wanted to operate in SSB
mode and did not noticed that a shift is still running. Therefore,
FM repeater shift or split mode is only on request available.


IF-Filter Bandwidth.
You can select the filter bandwidth “Wide”, “Medium” and
Narrow” separately for each mode.

                Wide           Medium          Narrow
                               (recommended)
SSB         3.6 kHz           2.4 kHz          1.8 kHz
CW         1.6 KHz**         0.9 kHz**        400 Hz**
FM/AM   15.0 kHz         10.0 kHz          7.0 kHz

** For CW decoding/ monitoring I use „CwGet“ (UA9OV)  in parallel
    or using HRD / MixWin as well.


CW.
If you want to receive CW, PSK31 or Digi signals in “SSB” mode, be sure
that the auto notch filter "ANF" is switched off, than it works very nicely.

At “CW” RX mode the notch filter is disabled and narrow filters are
in service.

For CW Freaks: Following IF kHz section combinations can be used:
3,6 LSB,  2,4 LSB,  1,8 LSB,  1,600 CW,  0,900 CW,  0,400 CW.

CW TX Simple Made
A simple way enabling CW TX mode is to use LSB mode on (any) remote
station. Just use MixWin3 in CW mode and generate CW TX audio signals
with the PC keyboard using macros, that's all.

The CW enthusiast preferring a normal paddle against a keyboard.
For this purpose, an audio (side tone) generator controlled by
a paddle connected to the microphone socket is required.

CW TX direct mode with paddle is due to difficulties not yet possible:

Therefore, please remember to reduce your transmit
audio in order to reduce the power output of the radio
down to say 30 watts or less, as most Digi modes are
100% duty cycle modes. Check on the drop down,
named TX Mtr that the TX power is below 30 % = 30 Watt.

RX Preselection “Tune”.
The used tuners are operating during receiving as frond end RX

recommended to press "Tune" button, in order to get the antenna
tuner also moved to the new dialed band, keeping the RX sensitivity
constant high!

Contest Operation. 
This remote is not a Contest Station. It has not continues operation
performance. Therefore, do not use the IC-7400 for permanent
contest operations. I don’t mind, if some rapports will be issued!
http://www.qslonline.de/hk/eigen/remote.htm

http://www.qslonline.de/hk/eigen/remote.htm
Do not forget to add: DL/ in front of your Callsign.
For digital modes it is required as well.
Failure to follow can lead to consequences.


TX Antenna Matching “Tune”.
After a new frequency been dialed/tuned, push always "Tune"
button before transmitting. Make sure antenna has a low “SWR”
(check it by "Tx Mtr" indication function).


Meter Indication “Tx Mtr”.
You can toggle between meter indications:  
ALC”, “SWR”, “PWR” and “Comp” = compressor.
 

“Comp level” Slider
The compressor “Comp” level slider has following functions:
1) if your sound card has a too low mike gain level, it will help you.
2) For DX operation you can get more punch in the TX audio.
3) If your mike is missing the higher frequency part, it will help you.
The “Comp” button enables or disable the compressor function.

Several times happened that by mistake this function was engaged
during digital transmissions and thereby the TX audio emission
was distorted and overdriven. Therefore, it may be the case that
this function is inoperative too avoid manipulation on Digi modes.


Sometimes (40m) RF Problems.
Radio frequency interference (RFI) notes:
On 40m the transceiver can have RF feedback problems above
10 Watts transmit power. In the case, that RF Feedback takes
place, can be observed by RF output, which is not moving
synonymous with your mike audio level.  

The PWR is tending to remain permanently at a constant high
level and the transmitter audio signal will be distorted. Perhaps
you should ask for a modulation rapport.

If it is not good, than I highly recommend to reduce the TX PWR
down to a range of 10 Watt = 10% shown on the slider, which solve
the problem in most cases completely.



“Test” Button     Voice Chatting Intercom (TEST) Mode
This mode is like a conference mode without transmitting.
Most radio drivers have a “Test” button. When this button
is active, the radio will not be keyed up, but the VoIP will be
rerouted so (X) Users may make a conversation without keying
the transmitter (PTT).


“Mon” Button.
You can monitor all transmitted audio conversations of logged
in (X) User who are transmitting.


“SQL” Slider – IC-7400.
If the “SQL” slider is in use, set it to 21 is the best for FM and
for SSB it is than always open.


PTT.
"TX" with CTRL+T possible or use the marked “TX” (PTT) button.

"TX" with spacebar: The space has more than one purpose so
it cannot be dedicated to PTT.  However, you can temporarily
bind the spacebar to PTT. 

If the "TX" button is the last item you have "clicked", the spacebar
should be "bound" to PTT.

As soon as you click on something else, the spacebar is no
longer bound to PTT.


Internal HF Antenna Switch.
The transceiver has an internal electronical antenna switch
to toggle between:
Antenna One”  ANT 1 horizontal 52m Long-wire (80m-6m) and
Antenna Two”  ANT 2 vertical 2,5m VHF antenna (20-2m.  


HF "Antenna 1".
It is a 52 m long-wire End-fed antenna which is connected
always with an automatic long-wire tuner model IC-AH4
(160m - 6m). It is the best for RX and TX mode. No need use
on bands 160m-30m any pre-amp. It will have no advantage.

 
HF/VHF "Antenna 2".
A vertical mounted V-2000 Diamond antenna is connected to
the internal coax tuner which can be used alternatively for the
bands 20m-6m. Resulting in a strongly reduced urban noise
floor during RX mode. The pre-amp is always strongly required!


Advantages if "ANT 2" is Applied for upper HF Bands:
- On 10m e.g. it is nearly a 1/4-wavelength vertical pin.
- With a band opening, DX is possible!
- Due to the coax tuner and high on a roof mounted antenna 2,
   the efficiency is likewise a good vertical mobile pin, having
   strong reduced noise level compared to a long-wire mounted
   in a backyard through the trees!
- You can simply compare the antennas by remote. For example,
   listen to a station on 21 MHz and toggle to compare "Antenna 1"
   and "Antenna 2" by remote.

Experience: I apply the 6m section of this VHF antenna 2 regularly
in RX SSB mode on 20 m and upper HF bands, having an ultra-low
urban man made noise floor with a signal-to-noise (S/N) increase
of +10 dB (tested by WSPR) against my 52m long-wire antenna
on the 20m band!

Please note: However, the TX reachable distance performance
of ANT2 on 20m-10m is not that good as antenna 1. But in RX
mode the reachable distance can be much better, because ANT2
is mounted high on a roof having significantly less noise floor!


VHF Antenna.
For 6m the “ANT 1” (horiz.) or “ANT 2” (vert.) can be used.
For 2m the “ANT 2” is automatically selected.
Use always with antenna 2 the pre-amp2.


Frequency Dialing / Tuning by Shortcuts:
CTRL+RIGHT/LEFT                 =  0.1K steps
CTRL+UP/DOWN                     =  1.0K steps
CTRL+SHIFT+RIGHT/LEFT     =  10K  steps



VHF FM Memory Scan“.
Simply push “Scan” knob.
To resume, push the same knob 2x.



Convenient Frequency Tuning by Mouse Wheel Spinning.
If you have a mouse with a scroll wheel you can just hover
over a digit and scroll up and down to your hearts content.

Elegant solution: Set the mouse pointer over the VFO knob
"tuning knob" and select next to it your “Steps” and leave the
cursor over the “VFO” knob using the scroll wheel to step the
frequency either up or down.

The up and down mouse wheel frequency tuning by mouse
wheel is convenient like the handling on a real VFO knob.

Advantage of the preset 500 Hz steps: Since recent years
almost all SSB stations can be reached by 500 Hz steps!



VHF Memory Scanning “Scan”.
The IC-7400 memory bank (100 FM memories) will be
automatically scanned, when the "Scan" button is pushed.
To resume push “Scan” button again 2x.


Automatically VHF activity and DX Searching.
If the memory scanner stops at an SSB frequency on 10m, 6m
or 2m in “FM” mode, then quickly switch to USB mode, it might
be good DX conditions on the VHF bands or a Satellite signal crossing!



Remote Control DXing by Mouse Click Only.
How to move/change in one step transceiver frequency and
band instantly to a DX spotted frequency?


Simply open at top right hand side under Windows > "DX Spots"
and enter your callsign and select next to it a "dx cluster server"
followed by double-click to one of a listed “DX spotted station.
 
Whereby, the transceiver jumps instantly to that band and
frequency! Select manually the correct mode (e.g. USB/LSB)
by hand.



DX mode is limited
It should be noted, remote stations having reduced transmitting
power and using multi-band (compromise) antennas, among other
complexities, do not have the DX-business as an objective.
The unlimited long distance will be reached through Internet feature.

Android Handy / Tablet.
With Android system call up also the DX Cluster and press
Connect” and click 2x to a spotted station, there you go.

FAQ   –   Questions and Answers:

At what time is the remote daily online?
Remote service typically from 9:00 h - 23:30 h local time in Germany.


How many Ham operators having TX permission
on DL4EAI remote?

So fare 124 international / national licensed users having
TX privileges. 10 % of it are active users on this remote.
In total so far, more than 1000 visitors have dropped in.


How to use the (DL4EAI) remote effectivity for
transmitting operation?

Getting Started accessing the remote.
- Dial/tune to an interesting or free ham frequency.
- Select a desired mode: LSB, USB, CW, FM or AM
- Select the desired TX PWR (0-100 % = 5-100 Watt).
- Select / change available antenna “Ant 1” or “Ant 2”.
- Specialty for USB mode: select “Wide” or “Medium”.

- Check if the equipment is in simples not dup mode.
  Due to TX misuse only on request available.


Way I cannot hear sometimes any sound with SSB “Narrow” filter?
SSB “Narrow” is sometimes with 200 Hz reserved for digi mode.
Change to “Middle” 2.4 kHz SSB filter.



How can I connect direct to your remote station of DL4EAI?
You can access my remote either though the webpage under the
callsign DL4EAI at: http://www.remotehams.com/online.html

or load the RCForb Windows client software down and remote my
station though it by selecting DL4EAI.

A new 3rd possibility is, to run my remote portable through an
Android Smartphone App (not a fee ware).


Why do I hear no audio with my headset?
Probably at the client software for WIN RCForb under option the
sound card setting needs to be set to "Sound Direct".



Why is the TRCV power control slider sometimes missing?
In the Case when I am not close to the remote, I might copy the
following text in the chat window: For today the TX RF output power
is fixed / limited to 35 % of the maximum PWR.


Why, Upload Amateur License Copy?
Please upload a copy of your valid license, if you have not already
done so, on the RemoteHams.com page under "My Account".
Once uploading is sufficient, but it is like an obligation!


From what is a "TX" privilege dependent?
Connect to a remote, then you have to click the "TX" button
followed by clicking to the "Request" button to apply and waiting
for a TX permission.

What to do if RF Problems occur - bad report received?
Radio frequency interference (RFI) notes:
The transceiver perhaps can have RF feedback problems above
10 Watts transmit power. In the case, that RF Feedback takes
place, can be observed by RF output, which is not moving
synonymous with your mike audio level. 

The PWR is tending to remain permanently at a constant high
level and the transmitter audio signal will be distorted. Perhaps
you should ask for a modulation rapport.

If it is not good, than I highly recommend to reduce the TX PWR
down to a range of 10 Watt = 10% shown on the slider, which solve
the problem in most cases completely.


____________ My text for not TX activated stations ___________

Hello dear OM,
(callsign)

If you did not grand at present a TX privileges of DL4EAI, why?

No one has TX permission privileges by default. Remote owners having
sole responsibility awarding TX privileges. User must apply to
individually remote station to grant for a TX privileges.

How many TX permissions in total be granted by that huge quantity
of global TX inquiries made to a limited few Remotstation is
determined by each remote owners for themselves.

As known, many (X) Users can be logged in at the same time. But,
only one (X) User at a time can operate at the same remote
unlike with a WEB-SDR.

Therefore, a limitation e.g. through Club membership
(or like this letter) is not an exclusion (!) but it is a
useful way not to overload technically the transceiver and
avoiding to overstaff with user’s the remote!

With other words: If you have a TX permission on a remote which
is permanently overcrowded, it could be worthless for you.

In such a case it may be helpful, looking once for another newer remote.

By the way: uploading your license copy can support and accelerate
the verifying process.

Your license must also be CEPT equivalent and preferably show CEPT
recommendation if you want to operate in another country
of your own.

In the case that the usage activity on my Remote Station will allow
additional user privileges, I will respond again.

For your information, I have included the operating manual of
my remote. It contain many tips, which can be helpful by using
other Remote stations.

DL4EAI
__________________________________________________________

The “Tune” and “TX” function does not respond?
Perhaps someone has engaged the “Test” button beforehand.
It should then be turned off again. The function is
described above under "Test" button. You have no TX permission.


Listen With This Remote Station Online to
70cm FM Repeater Located Near Düsseldorf.

My permanent scanning ICOM IC-E91 passes received audio
signals from 70cm FM repeaters to the IC-7400 on a special
2m FM Cross-band frequency (1mW via dummy load).

When the frequency 144.019 MHz and the operating mode "FM"
"Wide" is tuned to the "VFO" on my remote station IC-7400,
then you hear active 70cm repeater signals in real time.


Local and Remote Memory Bank.
A)  This particular cross-band frequency in addition to other
      frequencies stored by me, can be conveniently accessed
      from the remote memory bank in the Windows or Android
      client software!

B)  However, if the "local bank" and "Add" is selected, you
      can save yourself a favorite frequencies with additional
      features into your own client software!
      For example: Club and DX-frequencies on various bands.

Requirement.
Please do not occupy this transceiver permanently
over hours in one session. Because, I myself
    - DL4EAI as RIG owner,
    - privileged (X) Users, ham newcomers as well as
    - guests and propagation testers
want to share this remote as well!



Remote Service for HAM Radio Applications.
The free of charge service of this private financed amateur radio
equipment should not tempt to replace own station investments!
It must also not be used for commercial applications.


At My QSO End.
I usually reduce the TX power of my remotely controllable home
station mostly down to a minimum of 5 Watts. It is better for a long
life of the tuners and the filter relays!

In other words, if you want to transmit "TX" please increase by
yourself the "RF Power" slider control "5...100 %" to your request.
If no slider visible, occasionally I have set the TX PWR to 40 Watt
or less for applying digi modes.


Combining RemoteHams and WSPRnet.
RCForb Server has the ability to set a "Memory" as a "home"
frequency. This will make the server return the radio to a favorite
spot (memory) when no one is connected. At this point one
should be able to leave the WSPR software running "decoding"
whatever the radio hears.

If you have any question, please feel free to contact me.
I wish you good luck!

RX/TX Remote Experience with Digi Modes.
End of 2015 DM5SR Stephan near Cologne Germany
and beforehand 2W1SWW Phillip from Cardiff Wales
could successfully perform PSK31 (SSTV, CW) with
HRD v6 / MIXWIN v3 on the remote of DL4EAI.

To be able to perform digital RX and TX operation
both applied virtual Audio Cables (VAC)!

My pleasure was, I attended that test and could monitor
above mentioned client stations coming through the
internet as well as the on 80m replying stations.
 
I decoded the PSK31 CW etc. signals in real time with
HRD v5 on my RCForb server PC located in Duesseldorf.

Note: To protect the transmitter at digital Modes, the
transmit power must be reduced to less than 30% of
the maximum transmitter output power of 100 Watt!



Quick Guide for Digital mode via RemoteHams:
DM5SR Stephan south of Cologne has published
instructions how to apply digi modes on remotes
in detailed here:
http://z11.vfdb.org/remotehams/

Virtual Audio Cables (VAC).
If you want to execute digital mode on the same Windows PC
trough RemoteHams.com, RCForb Client, than you need perhaps
an Virtual Audio Cables (VAC) for PSK31/ SSTV / WSJT-X JT65
etc. operations.
http://vb-audio.pagesperso-orange.fr/Cable/index.htm

For digital mode (WSJT-X) you need two VAC's client side.
One will connect the playback device  (transmit) of your digital
software to the microphone on the client. The other will connect the
speaker of the client to the record device (receive) in the digital software.

die Signalausbreitung zu überprüfen.


Lizenzkopie hochladen?
Bitte laden Sie Ihre gültige Lizenzkopie, wenn Sie dies nicht bereits
getan haben, auf der RemoteHams.com Seite unter „My Account
hoch. Einmal Hochladen genügt. Dies ist wie eine Verpflichtung!


"TX" Privileg erbeten 
Verbinden bzw. connecten Sie sich über die FCForb Client Software
mit einer Remote, dann müssen Sie einmal auf die „TX“-Taste und
anschließend auf die "Request“-Taste klicken um eine TX
Genehmigung zu beantragen.

Information zu TX-Privileg, siehe Fragen und Antworten (FAQ).


Verbindungs- und Unterhaltungs-Formalität.
Wenn niemand sonst eingeloggt ist, können Sie ohne zu fragen
die Frequenz und weitere Funktionen einstellen und vielleicht
auch den Transceiver zum Sendebetrieb "TX" bedienen.

Um zu vermeiden, dass ich für andere juristisch verantwortlich
gemacht werde die illegale Kommunikationen und Handhabungen
mit Hilfe meiner Remote Station ausüben, ist die Kommunikation
vorzugsweise in deutscher oder englischer Sprache erfolgen.

Ausländische Betreiber identifizieren sich mit DL4/Rufzeichen.

Empfang "RX".
Nutzbare Bänder: VLF / LF / MF / HF und VHF.

Empfangs-Frequenzbereiche:
0,03 MHz bis 60 MHz,
144 MHz bis146 MHz.

Der CB-Funk Bereick“ h ist an dieser Remote gesperrt.
Testen Sie freie fernsteuerbare Empfänger:

"Lock" Frequenz-Loktaste - Android Sys
Wenn Sie den Sendevorgang im Android-System starten wollen,
empfehle ich vorher die Tastenfunktion „Lock“ zu betätigen!


Bertiebsart-Wahl.
Es kann die Bertriebsart: „LSB“, „USB“, „CW“, „FM“ und „AM
ausgewählt bzw. ausgeführt werden.

Bitte prüfen Sie ob nach einem Bandwechsel die Bertiebsart
mit umschalten müssen (z.B. LSB nach USB beim Wechseln
von 10 MHz nach 14 MHz und zurück).


Repeater-Ablage und Split-Betrieb.
Es kam vor, dass Nutzer in SSB-Betrieb arbeiten wollen und nicht
bemerkt haben, dass noch eine Ablage eingeschaltet war.
Daher ist eine FM-Ablage oder Split-Betrieb nur auf Anfrage verfügbar.


ZF-Filter Bandbreite.
Es kann die Filterbandbreite „Wide“, „Medium und „Narrow
für jede Betriebsarten getrennt gewählt werden.

                          Wide              Medium           Narrow
                                                (empfohlen)   
SSB:                3.6 kHz             2.4 kHz            1.8 kHz  
CW:                 1.6 KHz**         0.9 kHz**          400 Hz**   
FM/AM:           15.0 kHz,          10.0 kHz           7.0 kHz

** Zur CW Dekodierung (Monitoring) nutze ich parallel „CwGet“ (UA9OV),
    HRD oder MixWin.


CW.
Wenn Sie CW PSK oder Digi Signale bei der Betriebsart „SSB“ empfangen
möchten, achten Sie darauf, dass die Auto-Notch-Filter-Funktion
"ANF" ausgeschaltet ist.
 
Die Notch-Funktion ist bei der „CW“-Betriebsart abgeschaltet und
schmalere ZF-Filter werden zugeschaltet.

Für CW Freaks: Folgende ZF-Bandbreiten (kHz) Kombinationen wählbar:
3,6 LSB,  2,4 LSB,  1,8 LSB,  1,6 CW,  0,9 CW,  0,400 CW

CW TX einfach gemacht
Der einfachste Weg ist es, an einer (beliebigen) Remotstation im LSB Modus
CW TX Audio Signale zu senden. Verwenden Sie dazu einfach MixWin3 im
CW-Modus und generieren die CW TX-Zeichen mit der PC-Tastatur via Marcos,
das ist alles.

Der CW Enthusiast wird ein normales Paddle gegenüber dem Keyboard
bevorzugen. Dazu wird dann ein NF-Tongenerator benötigt der mittels
Paddel tastbar ist und an die Mikrofonbuche angeschlossen.

Die direkte CW Sendefunktion mit paddle ist aus technischen Gründen
noch nicht möglich:

TX Leistungseinstellung bei Digitalbetrieb
Hinweis: Zum Schutze des Senders muss bei digitaler
Betriebsart die Sendeleistung auf weniger als 50 % der
maximalen Ausgangsleistung von 100 Watt reduziert werden!


Deshalb denken Sie bitte daran, Ihre Sendeaudio zu reduzieren,
um die Ausgangsleistung des Funkgerätes auf unter 30 Watt zu
reduzieren, da die meisten Digi-Modi 100% Sende-Einschaltdauer
(TX) haben! Überprüfen Sie auf den Dropdown Menü namens
TX Mtr, dass die Sendeleistung unter 30% = 30 Watt befindet.

RX Vorselektion "Tune" nutzen.
Die beiden Tuner arbeiten beim Empfang als Empfänger-
Vorselektion. Dies erfordert, dass nach einem Bandwechsel,
es immer empfehlenswert ist, die "Tune"-Funktion kurz zu drücken,
um die Antennen-Tuner anzuweisen auch auf das neu gewählte
Band zu folgen, damit die RX-Empfindlichkeit konstant hoch bleibt!

Ein S-Meter Anstieg von typisch 2-4 Stufen und die Audiowiedergabe
bestätigen ob nach kurz gedrückter "Tune"-Taste auf den KW Bändern
die Signalfeldstärke angestiegen ist (Nur für (X User nutzbar).
 

Gemäß IARU Region 1 Erlaube Sendefrequenzen.

Contest-Betrieb.
Bitte beachten Sie, dass diese Remotstation keine
Contest-Station und nicht für Dauerbetrieb geeignet ist:


Deshalb verwenden Sie bitte nicht den IC-7400 als Contest Station.
Ich habe nichts dagegen wenn einige Rapporte gegeben werden!
http://www.qslonline.de/hk/eigen/remote.htm
Vergesse nie DL/ dem eigenen Rufzeichen voranrzustellen.
Dies gilt auch für digitalen Betrieb.


Nicht befolgen kann Konsequenzen mit sich bringen.


TX-Anpassung "Tune".
Nachdem eine neue Sende-Frequenz gewählte wurde ist vor
Sendebeginn die "Tune"-Taste zu drücken, um die Sender-
Anpassung an die Antenne zu gewährleisten. Stellen Sie
sicher, dass die Antenne ein geringes „SWR“ hat

(Kontrollieren über die Funktion "Tx Mtr").


Anzeige-Instrument  –  “Tx Mtr”.
Mit der "Tx Mtr" Anzeigefunktion lässt sich zwischen
ALC-, SWR-, PWR“- und „Comp“ (Kompressor)
Meter-Anzeige umschalten.


"Kompressor Schieberegler “Comp level”
Kompressor "Comp“ Schieberegler verfügt über folgende Funktionen:
1) Falls Ihre Soundkarte zu niedrige Mikepegel liefert, hilft es Ihnen.
2) Beim DX-Betrieb können Sie mehr Punch für die TX-Audio einstellen.
3) Wenn Ihr Miko zu dumpf klingt, dann wird es Ihnen einfach helfen.
Die Schaltfläche "Comp" aktiviert oder deaktiviert nicht vergessen.


Es ist mehrfach vorgekommen, dass diese Funktion versehentlich
bei digitalen Übertragungen eingeschaltet war und dadurch die
Aussendung verzerrt und übersteuert war. Deshalb kann es sein,
dass diese Funktion außer Betrieb ist, um Manipulation an Digi-
Modes zu vermeiden.


Manchmal HF-Einschränkung auf 40m möglich.
Hinweise zu Hochfrequenzstörungen (RFI).
Auf 40m kann der Transceiver HF-Rückkopplungsprobleme
(HF-Einstrahlung) oberhalb 10 Watt Sendeleistung haben.
Ob HF-Einstrahlung auftritt, erkennt man daran, dass die
HF-Ausgangsleistung dem Mikrofonpegel nicht synchron folgt.

Die Ausgangsleistung neigt dann dazu, dauerhaft auf einem
konstant hohen Niveau zu verbleiben und das Sender-Audiosignal
wird verzerrt. Bei Verdacht sollte man Sicherheitshalber nach
einem Modulationsrapport fragen. Fällt der schlecht aus,
empfehle ich, die „TX“-Sendeleistung auf einem Bereich um
10 Watt zu reduzieren, damit wird das Problem in den meisten
Fällen vollständig behoben sein.



"Test"-Taste - Intercom (TEST) mode
Diese Betriebsart ist wie ein Konferenz-Modus ohne zu senden.
Wenn die „Test“-Taste betätigt wird, sendet der Transceiver nicht.
Aber die VoIP Audio-Kanäle werden umgeleitet, so können sich
die (X) User unterhalten ohne den Sender (bzw. PTT) zu nutzen.


"Mon"-Taste. Hierdurch können Sie alle gesendeten
Audiogespräche von mit eingeloggten (X) Benutzer mithören.
Hinweis: Meist nicht verfügbar.


“SQL”-Schieberegler der Rauschsperre beim IC-7400.
Ist der „SQL“ Regler aktiv, dann ist die beste Rauschsperren-
Einstellung (SQL) die Position 21 bei FM. Für SSB ist sie dann
immer geöffnet.


PTT.
"TX" mit STRG + T möglich oder
nutzen Sie die „TX“ (PTT) Sendetaste.


"TX" mit der Leertaste bedienen:
Sie hat mehrere Funktionen, daher kann sie nicht als reine PTT
Funktion festgelegt werden. Sie können jedoch vorübergehend die
Leertaste als PTT nutzen, wenn die Taste "TX" als letztes Element
genutzt wurde. Sobald Sie auf etwas anderes klicken, wird die
Leertaste nicht mehr PTT gebunden sein.


KW Antennen-Schalter.
Der Transceiver verfügt über einen elektronischen KW-Antennen-
Schalter:
Antenna One”  ANT 1 horizontal 52m Langdraht   (80m-6m) und
Antenna Two”  ANT 2 vertikal 2,5m VHF Antenn2 (20m-2m).


HF "Antenne 1".
Es ist ein 52 m Langdraht mit extern angeschlossenem
automatischen Langdraht-Tuner Modell IC-AH4 (160 ... 6m).
Es ist am besten geeignet für den RX und TX-Modus.
Auf den Bändern 160-30m bringen die Vorverstärker
keinen Vorteil.


HF / VHF "Antenne 2".
Eine vertikal V-2000 Diamond Antenne ist mit dem internem
Koaxtuner verbunden.
Für 20m ... 6m reduziert die ANT 2 den städtischen Störpegel
beim Empfang deutlich. Immer Vorverstärker nutzen!

TX Sendereichweite auf 20-10m ist jedoch nicht so gut
wie Antenne 1, aber RX-Modus kann besser sein!



Vorteile, wenn "Antenne 2" für die oberen
KW-Bändern angewendet wird:

- Auf 10m z.B. ist sie fast ein 1/4 Vertikal-Strahler.
- Mit einem Band Eröffnung, ist DX möglich!
- Aufgrund des Koaxtuner ist der Wirkungsgrad mit einer
  guten vertikale Mobil-Strahler für KW vergleichbar.
- Die hoch aufgehängte Dachantenne weist einen stark
  reduzierten Geräuschpegel im Vergleich zu einem
  Langdraht im Garten durch die Bäume gespannt auf!
- Sie können einfach beide Antennen miteinander vergleichen.
  Zum Beispiel, Sie hören eine Station auf 21 MHz und schalten
  zum Vergleichen zwischen "Antenne 1" und "Antenne 2" um.

Ich nutze den 6m Teil dieser VHF-Antenne 2 regelmäßig für
SSB-Empfang auf 20 m und höheren Bändern.

Die hoch montierte Antenne liefert auf 20m ein um +10 dB
verbessertes Signalrauschverhältnis (S / N)  mit WSPR
gemessen, gegenüber meiner 52m Langdraht-Antenne!

Die Sendereichweite der ANT 2 auf den oberen KW Bändern ist
dennoch nicht so gut wie die der Antenne 1. Jedoch ist die
Empfangsleistung, dieser hoch auf dem Dach montierten
Antenne, oftmals wegen des niedrigeren Rauschpegels
deutlich besser!


VHF-Antenne.
Für 6m kann die ANT 1 (horiz.) oder ANT 2 (vert.) verwendet
werden. Für 2m wird die ANT 2 automatisch ausgewählt.
Nutzen Sie den Vorverstärker 2.



Frequenzeinstellung mittels Tastenkombination:
CTRL+RIGHT/LEFT                 =  0.1 kHz  Schritte
CTRL+UP/DOWN                     =  1.0 kHz  Schritte
CTRL+SHIFT+RIGHT/LEFT      =  10  kHz  Schritte



Memory-SuchlaufScan“.
Zum VHF FM-Suchlauf, einfach nur „Scan“-Knopf betätigen.
Um den Suchlauf fortzufahren die Taste 2x drücken.


Frequenzabstimmung via Maus-Scrollrad.
Wenn Sie mit dem Mauszeiger auf die Frequenz-Digitalanzeige
zeigen, können Sie einfach am Maus-Scrollrad die Frequenz
dekadenmäßig ändern.

Elegante Lösung: Das gleiche gilt für den "VFO-Knopf" Abstimmung.
Bewegen Sie den Mauszeiger über den VFO-Knopf und ändern
Sie bequem die Frequenz auf- und abwärts am Maus-Scrollrad.


Neben dem VFO-Knopf kann man die Schreitweite ändern.
Jedoch ist die Voreinstellung 500 Hz sehr vorteilhaft:

In den letzten Jahren sind SSB-Stationen fast immer im
500 Hz Raster zu finden.



VHF-FM-Speicher Scannen „Scan“.
Die gespeicherten FM-Frequenzen im IC-7400 (100 Speicher)
werden automatisch gescannt, wenn die Taste "Scan" gedrückt wird.

Um den Scann-Vorgang fort zu setzen einfach die  "Scan"-Taste
erneut 2x drücken.


Automatische VHF aktivitäts- und DX-Suche.
Sollte der Suchlauf auf einer SSB Frequenz im 10m, 6m oder 2m
in Stellung FM stoppen, dann wechseln sie schnell in USB um:
Es könnten gute Bedingungen auf den VHF Bändern sein!


Ferngesteuertes DXing per Mausklick.
Wie ändert man mit einem Schritt die Transceiver-Frequenz sowie
das Band und springe zusätzlich direkt auf eine DX-gespottete
Frequenz? Die Betriebsart von Hand mit umschalten!
 
Oben im Client rechts unter Windows > "DX Spots" geben Sie
Ihr Rufzeichen ein und wählen Sie daneben einfach ein
"DX Cluster-Server" aus. Danach klicken Sie 2x auf eine
gespottete DX-Station, fertig! Wählen Sie evtl. manuell den
richtige Betriebsart (z.B. USB/LSB) von Hand.



Eingeschränkter DX-Betrieb
Es ist zu berücksichtigen, dass Remote Stationen mit reduzierter
Sendeleistung und Nutzung von Multiband-Antennen neben anderer
Komplexität, nicht das DX-Geschäft als Zielsetzung haben.
Die unbegrenzte Reichweite wir durch das Internet erreicht.


Android Handy / Tablet.
Im Android System rufen Sie DX-Cluster auf und bestätigen
Connect“ und los geht’s.



FAQ – Fragen und Antworten:

Wann ist die Remote Station täglich Online?
Minderst-Einschaltzeit der Remotstation:
9:00 Uhr – 20:00 Uhr Küchenzeit in Deutschland.


Wie viele Funkamateure haben Sendeerlaubnis „TX“?
Bisher haben 124 internationale / nationale lizenzierte Funkamateure
Sende-Privilegien „TX“ auf der Remotstation von DL4EAI.
Davon sind 10 % aktive Nutzer dieser Remote Station.
Bisher haben mehr als 1000 Besucher vorbei geschaut.


Wie startet man effektiv den Sendebetrieb an der Remotstation?
   - Stellen Sie eine interessante oder freie AFU Frequenz ein.
   - Gewünschte Betriebsart wählen: LSB, USB, CW, FM oder AM.
   - Sendeleistung wählen: TX PWR (0-100 %  =  5-100 Watt).
   - Gewünschte Antenne wählen: (Ant 1 oder Ant 2).
   - Spezialität für USB Betrieb: wähle “Wide” oder “Medium”.

   - Überprüfen Sie, ob das Gerät in Simples- nicht „Dup“-Modus ist.
     Auf Grund von TX Fehlbedienung nur auf Anfrage verfügbar.


Wieso höre ich manchmal keinen Ton beim SSB "Narrow" Filter?
Narrow” ist oft reserviert für Digitalbetrieb bzw. auf 200 Hz vor-
eingestellt. Wählen sie dann einfach das „Middle“ Filter 2,4 kHz.


Wie kann ich direkt die Remote Station DL4EAI erreichen?
Sie können meine Remote Station DL4EAI entweder auf der Webseite
über diesen Link  http://www.remotehams.com/online.html  oder
 
über die frei erhältliche Client-Software erreichen. Wählen Sie einfach
mein Rufzeichen DL4EAI in der Online Liste mit Doppelklick aus.

Eine weitere neue 3. Möglichkeit ist es über eine Android App
(nicht kostenlos) u. Smartphone meine Station portabel fern zu steuern.


Warum höre ich keine Audio mit meiner Sprechgarnitur?
Wahrscheinlich muss an der RCForb Client Software für WIN
unter Option noch die Soundkarten-Einstellung auf „Sound direkt“
umgestellte werden.



Warum fehlt manchmal der PWR-Schieberegler vom Transceiver?
Im Falle, wenn ich mich nicht in der Nähe der Remote Station befinde,
könnte ich den folgenden Text in das Chat-Fenster kopieren:

Für heute ist die TX HF-Ausgangsleistung begrenzt bzw. reduziert  
auf 35% der maximalen PWR.


Lizenzkopie hochladen, aber wie?
Bitte laden Sie Ihre gültige Lizenzkopie, wenn Sie dies nicht bereits
getan haben, auf der RemoteHams.com Seite unter „My Account
hoch. Einmal Hochladen genügt. Dies ist wie eine Verpflichtung!

Die Remote Besitzer haben Zugriff auf die Lizenzkopie, um zu überprüfen,
ob Sie tatsächlich eine Lizenz haben.


Wovon ist ein "TX" Privileg abhängig? 
Verbinden bzw. connecten Sie sich mit einer Remote, dann
müssen Sie einmal auf die „TX“-Taste und anschließend auf die
"Request“-Taste klicken um eine TX Genehmigung zu beantragen.


Was tun bei HF-Einschränkung?
Hinweise bei evtl. Hochfrequenzstörungen (RFI).
Der Transceiver kann evtl. HF-Rückkopplungsprobleme
(HF-Einstrahlung) oberhalb 10 Watt Sendeleistung haben.
Ob HF-Einstrahlung auftritt, erkennt man daran, dass die
HF-Ausgangsleistung dem Mikrofonpegel nicht synchron folgt.

Die Ausgangsleistung neigt dann dazu, dauerhaft auf einem
konstant hohen Niveau zu verbleiben und das Sender-Audiosignal
wird verzerrt. Bei Verdacht sollte man Sicherheitshalber nach
einem Modulationsrapport fragen. Fällt der schlecht aus,
empfehle ich, die „TX“-Sendeleistung auf einem Bereich um
10 Watt zu reduzieren, damit wird das Problem in den meisten
Fällen vollständig behoben sein.


_____________Mein Text für nicht TX freigeschaltete Stationen_____________

Hallo Lieber OM,
(Rufzeichen)

Es kann sein, dass sie z.Zt. leider keine TX Privilegien von DL4EAI,
erhalten, warum?

Niemand erhält automatisch eine TX Berechtigung. Remote
Eigentümer handeln für die Vergabe von TX Freigaben eigenver-
antwortlich. User (Benutzer) müssen TX Freischaltungen einzeln bei
Remotstation beantragen.

Wie viele Genehmigungen insgesamt, von den vielen weltweiten
Anfragen, auf den wenigen Remotstation erteilt werden,
bestimmt jeder Remote Eigentümer für sich selbst.

Wie bekannt ist, können viele (X) Benutzer gleichzeitig eingeloggt
sein. Aber es kann zeitgleich auf derselben Remote (im Gegensatz
zum WEB-SDR immer nur ein OM das Gerät bedienen.

Daher ist eine Begrenzung z.B. durch Clubmitgliedschaft
(oder wie dieses Schreiben) keine Ausgrenzung (!) sondern eine
sinnvolle Möglichkeit den Funkbetrieb an einer Remote technisch
nicht zu überlasten und nutzungsmäßig nicht zu überbelegen!

Andersherum.. was haben Sie von einer TX-Freigabe auf einer
Remotstation die ständig Überbelegt ist, sie könnte wertlos sein.

In so einem Fall kann es sinnvoll sein, bei einer anderen neueren
Remote einmal an zu fragen.

Übrigens: Das Hochladen Ihrer Lizenzkopie kann den Überprüfungs-
prozess unterstützten und beschleunigen.

Die Lizenz muss auch CEPT-Äquivalent und vorzugsweise eine
CEPT Empfehlung zeigen, wenn Sie aus einem anderen Land
heraus eine Remote im Sendebetrieb nutzen wollen.

Sollte die Nutzungs-Aktivität auf meiner Remote Station Neuzugänge
erlaube, werde ich Sie erneut ansprechen.

Zu Ihrer Information habe ich die Bedienungsanleitung meiner
Remote unten angehängt. Sie enthalten viele Tipps die auch an
anderen Remotstation nützlich sein können.

________________________________________________________

Die „Tune“- und „TX“-Funktion regiert nicht?
Es könnte sein, dass jemand die Test-Taste eingeschaltet hat.
Sie sollte dann wieder ausgeschaltet werden. Die Funktion ist
weiter oben unter „Test“-Taste beschrieben.


Wieso höre ich 70cm FM-Repeater aus
NRW auf der Remotstation von DL4EAI?

Mein permanent scannender ICOM IC-E91 überträgt Audio-
Empfangssignale von 70cm FM-Repeatern zum IC-7400 über
eine spezielle 2m FM Crossband-Frequenz (1mW via Dummyload).

Wenn man die Frequenz 144,019 MHz und die Betriebsart „FM
Wide“ mit dem „VFO“ an meiner Remotstation IC-7400 einstellt,
dann hört man in Echtzeit aktive 70cm Repeater-Signale. 


Lokal- und Remote Speicherbank  –  Memories.
A)  Diese spezielle Crossband-Frequenz neben anderen von mir
      gespeicherten Frequenzen können aus der „Remote
      Speicherbank
“ der Client Software für WINOWS oder Android
      bequem aufgerufen werden!

B)  Wenn man dagegen die „Lokal-Speicherbank“ und „Add
      aufruft, kann man selber Favorit-Frequenzen mit weiteren
      Merkmalen in die eigene Client Software abspeichern!
      Zum Beispiel: OV- und DX-Frequenz(en) auf diversen Bändern.
 
Weitere detaillierte Einzelheiten über die Fernsteuerung meines
IC-E91 sind auf http://www.qrz.com/db/DL4EAI näher beschrieben.

Forderung in eigener Sache.
Bitte nutzen Sie diese privat finanzierte Amateurfunkausrüstung
nicht dauerhaft über Stunden in einer Sitzung: Zum einen weil ich als
    - Gerätebesitzer DL4EAI und andere
    - privilegierte (X) User, Newcomers sowie auch
    - Gäste und Reichweitentester etc.
sich diese Remotstation von DL4EAI teilen!


Remote Service.
Die kostenlose Nutzung dieser aufwendigen Amateurfunkanlage
soll nicht dazu verleiten eigene Stations-Investitionen zu ersetzen!
Sie darf auch nicht für Kommerzielle Anwendungen genutzt werden.


Die Kombination Remotehams und WSPRnet.
RCForb Server hat die Fähigkeit, einen Remote Memory-Kanal 
als Home bzw. Favoriten-Frequenz ein zu stellen, nachdem
niemand mehr verbunden ist. Mein Gerät parkt öfters auf einer
voreingestellten Frequenz (Remote Speicher). Diese WSPR Speicher
können Sie auch aufrufen und mittels WSJT-X diese WSPR Signale
mit dekodieren oder Sie ändern die Frequenz um wo anders QSOs
mit der Remote Station zu fahren.

Ich nutze dann den Empfängerteil um WSPR auf diversen Frequenzen
oder WSJT (JT65) Betrieb mit zu schreiben. http://wsprnet.org


Bei meinem QSO-Ende,
reduziere ich in der Regel die Sendeleistung auf 5 Watt.
Es erhöht die Lebensdauer der beiden Tuner und Filterrelais.

Mit anderen Worten, wenn Sie auf Sendung „TX“ gehen wollen
erhöhen Sie bitte selbst den "RF Power" Schieberegler von
"0 ... 100%“  =  5 …100 Watt" bedarfsgerecht selber.

Wenn kein Regler zu sehen ist, habe ich gelegentlich die TX
PWR auf 40 Watt oder weniger eingestellt um Digi Modes zu
arbeiten.

Wenn Sie Fragen haben, zögern Sie nicht, mich zu kontaktieren.
Ich wünsche gutes Gelinngen und viel Glück!

Erfahrung mit Digital-Betrieb auf einer Remote.
Ende 2015 haben DM5SR Stephan nähe Köln
Germany und kurz vorher 2W1SWW Phillip aus
Cardiff Wales, mit Erfolg PSK31-, SSTV- und CW-Betrieb mittels
HRD v6 / MIXWIN v3, auf der Remote von DL4EAI durchgeführt.

Um digitalen RX- und TX-Betrieb durchführen zu können
benutzen Sie virtuelles Audiokabel (VAC).

Meine Freude war, ich konnte den Testversuch verfolgen
als die PSK Signale der oben genannten Client-Stationen, die
über das Internet kamen, als auch die auf 80m Antworteten
PSK Signale, begleiten bzw. beobachten.

Ich dekodierte die PSK31, CW etc. Signale in Echtzeit mit
HRD v5 auf meinem RCForb PC-Server in Düsseldorf.

Hinweis: Zum Schutze des Senders muss bei digitaler
Betriebsart die Sendeleistung auf weniger als 50 % der
maximalen Ausgangsleistung von 100 Watt reduziert werden!


Kurz-Anleitung zum Digital-Betrieb über Remotehams
DM5SR Stephan nähe Koblenz, Deutschland hat eine
Detaillierte Anleitung über Digital-Betrieb via Remote hier
veröffentlicht:
http://z11.vfdb.org/remotehams/

 

Wenn Sie digitale Betriebsart über RemoteHams.com auf
dem gleichen PC mit der Client Software durchführen
wollen, dann benötigt man:

Ein (kostenloses) Virtuelles Audiokabel (VAC) kann für
PSK31/ SSTV / / WSJT-X JT65 etc. notwendig sein:
http://vb-audio.pagesperso-orange.fr/Cable/index.htm


For digital mode (WSJT-X) you need two VAC's client side.
One will connect the playback device  (transmit) of your
digital software to the microphone on the client.
The other will connect the speaker of the client to the
record device (receive) in the digital software.

Sample: Reference Information.
I saw your TX request on my remote this morning. I didn't grant
your TX privileges because you uploaded a "reference" copy of
your license. Anyone with a computer and printer can produce a
reference copy. You need to upload a copy of your real license.

Sample: Remote Station is Outside Your Citizen Country.
When operating a remote in the USA, you must follow the FCC rules.
When operating a remote outside of the USA, you must follow that
countries rules.

If you were to operate on my remote, signing as KC9YFU/W6 is not
required.  It is the same concept as if you traveled to CA and used my
station. You would not be required to sign as / portable. You can ID as
callsign / remote. It is good to let others know how you are operating,
let them know where the transmitter is....

For foreign hams operating in the USA, they MUST is as prefix/callsign
(W6/callsign) according to FCC, CEPT or/and other reciprocal agreements
allow.
