DM0HEI-C Info as of Feb 6th: Our repeater in Schalkholz (near Heide) got a renewed 2m full duplex license effective immedeately: 145.650 MHz -0,6 MHz. We will go "online" probably in April. Also we can now start working multimode with 12,5 KHz bandwidth. We will inform here once the repeater operates on the new frequency - standard mode will be D-Star as part of XLX787C at first.

 

MMDVM Multi-Mode will start soon at least at some locations - I am currently working on it....

Here is a full MMDVM Raspi-Image to get you started right away. The image can handle repeaters in multi-mode but can also be used for local hotspots based on a DV-MEGA. All you need is a pi2 or pi3, a small TFT display (optional) and a DV-MEGA or you set it all up with an Arduino and a MMDVM-board for real repeaters - a 23 pages documentation in German is available as well:  (size is ~1,8 GB)

D-Star XLX Net Agenda:

 

Here are our Dashboards:    http://xrf787.de      http://xrf747.de      http://xrf767.de

 

 

Welcome to our   NorthStar  XLX747 / XLX787 information site

Welcome to the first (digital) network in North Germany with coverage from south of Bremen all the way up to Denmark and to Rostock in the East (We went online already back in August 2012 - providing service since more than 4 years now!) 

We build our net from scratch - there was simply nothing in Schleswig-Holstein back in 2012. We homebrew all our repeaters (actually we had to develop them) and all our servers - all based on small ham fitting budgets and based on Ham spirit. (No commercial repeaters and also no commercial towers - this would have been too easy and wouldn't be us).

So we planned it all based on small cells - providing highest reliabilty along with highest flexibility.....knowing that we will have to create a couple more repeaters.

We were always driven by ham spirit. Our motivation and goal was providing coverage for all of us AND bringing "rf-positive" people together - forming a creative team; those who have fun to build things themselves - no matter if it´s network technology or a new repeater.

Do you intend to launch your own repeater as permanent part of our net? Please contact us. We are more than happy to list you here as well.

Last but not least, enjoy all the information below - hope we can get you inspired as well....If you want to join our team please don't hesitate and contact us right away!

 

 

On October 2nd we now launched step #3 - our brand new  XLX 787!  Click here:  http://xrf787.de

XLX 787 is our first multiprotocol reflector which went online now. It handles easily XRF (DExtra), REF (US-Trust) and DCS/CCS machines. Our Module "C" became already our main module in North Germany. All our DX machines (mainly 2m) are right there. Also REF006C is linked to us.

Did you know that XLX grew to ~ 120 reflectors wordwide already? What a big story in just about half a year! Well done Luc, LX1IQ!

XLX 747C hosts most of our 70cm repeaters - our secondary net.

 

What is new with XLX Reflectors? Well, since we are using multiprotocol you can now connect via XRF (DExtra), REF (DPlus) or even DCS/CCS....it is your choice! DMR, C4FM and other bridges will follow. And it will be all digital!.....(no analoge voice bridges).....

 

Note: There are just 2 things you need to add / modify:

1) Hostfile Information - you need to update these accordingly (don't forget XLX747):

  • For XRF / DExtra please add this line into the DExtra Hostfile, typically named "DExtra_Hosts.txt":    "XRF787    xrf787.de"
  • For REF / DPlus please add this line into the DPlus Hostfile, typically named "DPlus_Hosts.txt":         "REF787    xrf787.de"
  • For DCS / CCS please add this line into the DCS Hostfile, typically named "DCS_Hosts.txt":                "DCS787    xrf787.de"

2) Ports which need to be opened in your router - depending on your preferred protocol:

  • For XRF (DExtra)           UDP 30001
  • For REF (DPlus)             UDP 20001 - 20009 (usually 20001)
  • For DCS                         UDP 30051 - 30059 (usually 30051)
  • For CCS                         UDP 30061 - 30065 (usually 30061)
  • For ircDDB Routing      UDP 40000              (optional)

3) Once #1 and #2 are done, reboot your system and you are good to go:

  • You can now connect via XRF787 or REF787 or via DCS787....try it out! 
  • Watch your activities here: http://xrf787.de

 

In terms of growing XLXs bypassed XRFs already - they are really growing fast - here are two screenshots (examples) of our newly started XLX 787 - just go there to get it "live": http://xrf787.de

Current Network Status in short: 

 

  • Ferbuary 6th 2017 DM0HEI-C got it's new 2m full duplex license today! The new coming frequency for the repeater is 145.650 MHz (-0,6 MHz). The license got also extended for multi-mode @ 12,5 KHz. We will inform here once the repeater made qsy.

 

  • December 18th 2016 DM0HEI got inspected by our German authorities "BNetzA" - everything passed with flying colors as expected. We also upgraded the 70cm repeater with a new 5 dBd 70cm Procom antenna "CXL 70/5 Cl" and invested in new HyperFlex coax for both repeaters along with a new computer for the 70cm machine (the old died unexpected). So please check it out and let us know if both machines do their job :-)

 

  • November 18th 2016 See the latest and greatest digital toy below - the wonderful DVMega on top of a BlueDV board created by David, PA7LIM. Now it's super easy getting online in D-Star, DMR and also in C4FM. No PC or raspberry needed - all stand-alone and controlled by your cell phone! For more info please scroll down to the "dongle section"......

 

  • November 10th 2016 Since today also XLX787 is completely remote accessable. A seperate LAN interface and remote S/W is now in place. Since today all our 3 reflectors are totally remotely programmable. They can also be disconnected from mains if necessary. 

 

  • November 5th 2016 Today we launched the all new XLX747 and created a new gateway reflector in order not to lose REF006C....."XRF767".  Now since we are running 3 reflectors we had to move them to 3 different locations. And all 3 moved today and found new homes! The new interlink logic can be seen above.....

 

  • October 2nd 2016 Another important step: On Ocotber 2nd we launched XLX787 - our first real multiprotocol Open D-Star Reflector. More or less over night it became our new home for most of our activities. Please feel free and check it out and meet us there: http://xrf787.de 

 

  • August 29th 2016 Once again we had to extend our data volume of our two LTE (4G) repeaters in Laboe. We now excceded 7 GB/month! Well, good news - since more and more people are using our net and join "Open D-Star". We now have extra GBs ready for you in Laboe. So please feel free and enjoy our net!

 

  • June 9th 2016 Today we launched our latest baby, the XRF787. Currently we run our 2m and DX repeaters on XRF787C and 70cm mainly on XRF747C. XRF787C  is linked to XRF747D and also to REF006C. So we can offer way higher reliability by using 2 independent reflectors from now on.

 

  • May 30th 2016 At this point "special thanks" to  Timm, OE5STM  who spent endless hours not only over the last weekend on re-programming the S/W of our reflector. Stability issues became a major issue since we moved to our new location and in parallel from REF006 to XRF747 with some 40 participants and partly more. Tests will be continued as always -  Isn't it exactly what's Hamradio is all about?

 

  • May 26th 2016 DB0DWL-B went online today. Location is in the heart of Luebeck, 50m above sea level. Please test this new repeater and provide reports to the proud owner Jan, DL2HBJ! Great job Jan - Your baby can be heard here in Ellerhoop some +60km away!

 

  • April 27th 2016 First time in our history we reached 10 GB data volume in summary on our 3 GSM repeaters DB0DMB-B, DB0DMB-C and DB0MAR. Our volume exceeded - so I had to extend our existing LTE-contracts, effective May 1st.

 

  •  March 8th 2016 DB0IZ-B has now also an Echolink-Bridge to D-Star, node 397857 (Thanks Jürgen, DG4JC)! Please feel free to test via DB0IZ-B which is linked to XRF747D. For connections within our D-Star network you will need to use DTMF.

But now first of all, a "Very Warm Welcome" to our German D-Star Repeater Net in Schleswig-Holstein, Germany's northern-most county - the only VHF/UHF net up here in the north with coverage from coast to coast and from Bremen in Niedersachsen, Hamburg and all the way up to Denmark. 

We are at home at XLX 787 (primary) and also on XRF 747 (secondary) - our own XExtra reflectors.

All you need to know is probably here on this website - this includes latest status of all our repeaters. If you miss anything please let me know. There will be frequently new things to come.

 

yes Most of the infrastructure would not be in place without all the work & help of Jürgen, DG4JC - so again special thanks Jürgen!

But we had also strong supporters, movers and promoters, like

Michael, DL3HCC - Ingrid, DJ2IR & Jürgen, DN2IR (sk) - OV E11 in Timmendorfer Strand, especially Jochen, DK8XN & Lothar DD2HS

Thank you again folks for making all this happen!

Our clear goal: We'll provide coverage for "all" of us.

 

In only 3 years (we started it all in summer 2012) Ref6C became "a digital home" for many HAMs across Germany. In October 2015 we launched XRF747 as our new additional playground. We moved there permanently in May 2016. On Ocotber 2nd 2016 we launched XLX787. Today XLX is aready our our main place and hosts most of our repeaters.  

Feel free to test your latest gear, test our repeaters, stay in contact with friends, stay in contact with our admin-team and have fun & enjoy. That's why we invented, invested, created and build it.

- First test repeater running on Futro A-250 and 16 GB SATA SSD instead of CFII-card (compact flash)

The well known Futro A-250 uses normally a 4 GB CFII card - better known as Compact Flash II. These cards do not allow endless write/read cycles and therefore cause problems over time. Aside this CFII is pretty slow and sometimes not easy to handle as exact sizes vary by manfacturer. SSD-HDs allow millions of write-cycles and boost the mini pc to new limits. Reliability and speed increase enormous. The fully installed repeater (incl. Windows) starts in just 45 seconds - total DC-power consumption increased to 10 Watts when LAN is active versus 8 Watts with CFII before. Here is our first test installation under Windows XP Pro - we now use the internal IDE-interface, convert it to SATA (Common SSDs have SATA) and installed 1 GB internal DDR RAM:

 

This is the Converter SATA -> IDE available from Reichelt Elektronik:

 

November, 26th 2015

- DB0EAT got a new WiFi bridge to it's shelter - here are some pictures showing the modification:

We used already the well-known FritzBox 7390 - so the little FritzRepeaters could do an excellent job but have no external antenna jack - also only the bigger ones have an external LAN-connector. Therefore do NOT buy the small version, called 310! The best versions are the Repeater 300E and/or 450E (left model). Real world speed to the repeaters is 120MBit now (up and down).

 

March, 31st 2015

- New 145 Mc duplexer for DB0EAT-C arrived. The new duplexer for DB0EAT-C came in today - we choose IK Telecom in Finland. http://www.duplexers.eu/catalog/2m/Duplexers/dpre5_6v/  It is planned to modify and extend DB0EAT-C any time soon.

Here are a few first images:

   

 

March, 9th 2015

- DN2IR, Jürgen Rückbrodt from Handewitt - SK  Our good friend Jürgen died unexpected in the age of only 63 on Monday March, 9th 2015. Jürgen was seriously ill since many years but he was one of our big supporters and helped us whenever possible. Two repeaters run still at his place, DB0IR-B and DB0IR-C. We miss you Jürgen - you have been a real friend for us. God bless you.

 

December 2014:

- DB0DMB & DB0MAR upgraded. The photo below shows our latest piece of internet-technology. This little "Dovado Tiny" LTE router is now providing stable Vodafone speed . It can handle LTE @ 150MBit/s via the new "K5005H" - modem but HSPDA has better average - so we use that today. It can be programmed and even reset via SMS (from my cell) and provides WiFi capability near the repeaters as well. So easy accessing, programming and easy remotely controllable.

DB0DMB has 2 repeaters (2m and 70cm) and DB0MAR has one (70cm) - all three are now RJ45-router connected. The former server/client configuration took too many resources of the little Futro-PCs and slowed them down - it never worked perfect when both repeaters were operating.

 

July 10th 2014:

- DB0MAR-B in Timmendorfer Strand, the legendary Bäderstrassen-Relais went online "digital"  today, July 10th at 10:30am. More details see below under section "DB0MAR". No worries, the analog repeater on 2m (145.700 MHz -) stays of course alive!

At this point, many thanks Jochen, DK8XN and your team for all your kind support, your trust and your time! Also special thanks to Heinz, DK4LP for your support!

You like our repeaters? 

 

     

 

 

As you can probably imagine we spent a lot of private money to make our network happen - especially for repeater hardware, professional antennas, coax-cables, duplexers, diplexers, PCs, racks, operating-licenses but also on significant ongoing costs, like electricity and internet (LTE contracts and landline). If you like our net and enjoy the coverage throughout greater Schleswig-Holstein you can make a donation. Here is how - your help is much appreciated.

The todays coverage of "Our friendly Net" on XLX747 / XLX787  - (Calculation provided by TowerCoverage.com):

 

Michael, OZ5WU is SysOp of OZ0REA, OZ0REB, OZ0REC, OZ0RED, OZ0REF and OZ0REV. He informed us that several new repeaters will be added to the D-Star Net in Denmark soon. All of them will be also usable for REF006C - this looks like a perfect extension towards the North - coverage from Flensburg to Copenhagen and also from Fehmarn to Copenhagen. Many thanks Michael and good luck for all your good work!!

DB0EAT in Ellerhoop faced a complete restructuring of it's VHF / UHF antennas - completed after 5 days work on August 24th 2014.

And how does DB0EAT look today?

All 3 Procom verticals are now on top - mounted on a custom-made stainless steel structure. In addition a 22-element 2 x 70cm Flexa Yagi stack got installed and also a single 4 element Flexa Yagi for 2m. All those antennas are vertical and got also low noise Pre-Amps and low loss Ecoflex 15 coax cables.

The 9 element Optibeam OB 9-5 for HF, the 23cm Flexa Yagi and the 11 element 2m horizontal Flexa Yagi remained untouched.

 Important Registration Info for DPlus:  

Before you can use our network via REF006 (or any other REF) you MUST have registered here. Use this link to register - this is a 2-step registration procedure:

If you are not registered you will not be forwarded - regardless which repeater you are using. You will operate locally only! Nearly nobody will hear you.....this can be very disappointing :-(

So please proceed this way:

Click https://db0hrf.no-ip.org/Dstar.do (Please allow access to this website when warning pops up)

Once your registration went through make sure you go back and enter at least one terminal address. But before you start working on step #2 please allow one day time for internal server updates....this procedure takes some time.....

Once you enter step #2 (second day) please fill out at least one line (of 8 possible) - so make sure you have at least one valid IP-address. The initial-field needs to be entered with your coursor....you need to fill in one blank character. This sounds crazy but it is not enough to leave it simply empty. You need to enter that initial-field and fill in one blank character.

Remember: Since this is a 2-step registration you need to work on both steps before you are registered successfully.

Now allow another day before you check your status again here: http://dstar.prgm.org/cgi-bin/dstar-regcheck

You are good to go on US-Trust once your status says "Registrierung YourCall Ok". Now you should be okay to work all US-Trust reflectors. Congratulations and welcome on our Net!!

Some Linking Instructions:

Here is how you can link repeaters - related UR-commands:

Repeater will report current status - UR = _ _ _ _ _ _ _I ("I" must be the 8th letter)

Repeater will unlink from any refelctor - UR = _ _ _ _ _ _ _U ("U" must be the 8th letter)

Repeater will echo your voice (for tests) - UR = _ _ _ _ _ _ _E ("E" must be the 8th letter)

Examples:

Repeater will link to our DCS787C - UR = DCS787CL

Repeater will link to our reflector REF006C - UR = REF006CL

Repeater will link to REF014C - UR = REF014CL

Repeater will link to our XRF747B - UR = XRF747BL

Call Sign Routing via CCS7:

How to call somebody? And how to disconnect later? First please get your partner's CCS7 ID, f.e. mine is 262-2045. Then keep in mind that you disconnect from your reflector once your call-sign routing connection is established. The call-sign routing has higher higher priority and will not get disconnected even when your repeater leaves the reflector. If you do NOT disconnect from your last reflector the world will still listen to your qso. This is probably not what you intend.

CCS7-Call:

Via UR: C2622045 (Example, please use your partner's CCS7 ID)

Via DTMF:  2045 (Example, Please use your partner's CCS7 ID)

 

CCS7-Disconnect: (Disconnect will also happen after 3 minutes of no activity)

Via UR: CA _ _ _ _ _ _  (Use the 2 first digits and leave 6 blank)

Via DTMF: A

 

Call Sign Routing via DPlus and ircDDB:

Personal DPlus Call only via UR: DL6EAT (Example, please use your partner's call)

Repeater DPlus Call only via UR: /DB0IR_C (Example, please use the repeater's call which you intend to call on and add mode on the 8th digit)

Disconnect is not possible....

Info: Did you know that there is a cell phone App called "Repeater"? Once installed it provides a good overview what's up and running around you (not only D-Star). It uses your GPS-location and shows you repeaters which are located in your neighbourhood. Please check your Play Store or your iStore. It is available for Android and Apple-users.

Hi all, some background info...

"Welcome and many thanks for visiting DB0EAT" on QRZ.com. This is the call sign of our 70cm Repeater and 2m Hot Spot D-Star machines in Ellerhoop.

Quick about myself: My name is Andreas (Andy). Since 1980 my personal call is DL6EAT - I also hold W6EAT, US Extra Class since early 2012. I am mostly active on 80m and 40m in SSB - also doing DXing on 20 and 17. For more infos about HF-projects please visit www.duessler.de or www.qrz.com/db/DB0EAT

I started my first D-Star activities back in 2007. Since 2011 I concentrated a bit more on getting more folks interested in this new fast growing fascinating digital mode. Our county (Schleswig-Holstein) had no digital repeater network at this time - only one repeater was "on air" (DB0IZ-B in Itzehoe). Therefore I planned filling gabs between our sea port city Hamburg and Denmark over time. Accidently my private location is about 20 miles north-west of Hamburg.

Unfortunately the terrain is all flat - so we all suffer a bit of superb repeater locations. We started the net back in summer 2012 - today we achieved pretty good coverage in our county Schleswig-Holstein.

 

Here are some D-Star toys made by Icom helping you getting started in D-Star:

This is the all new ID-5100 replacing the old and dusty IC-2820.....now with build-in GPS, touch-screen, Bluetooth and a better dual-watch and dual-band DV-Mode Prio RX! The ID-5100 is not perfect but for sure currently the best on the market...

It also comes with 2 x 12,5 KHz filters, one for each band. True narrow band receiving on both bands and/or different modes at the same time is now possible.

Picture shows Display head only - the radio itself is separated by a 10 foot cable (not visible):

Info:  Modification Info - better modulation for D-Star mobile rigs:

Some may have noticed a pretty "metallic sound" especially on the ID-880 and the very old "IC-2820H". The info below published by Hans-Jürgen, DL3NDS covers the ID-880, the IC-2820H, the ID-5100 and the IC-7100 and may be very useful:

http://www.db0wun.de/MIC.html

 

And here are some digital hand-held toys:

  • Tytera MD-380:     5W Monoband, Modes: DMR / FM, Color TFT, 2800 mAh Battery, Charger, Data Cable ~ 75,- € in China, ~130,- € in DL
  • Icom ID-51:           5W Dualband, Modes: D-Star / FM, Large High Res.TFT, 1880 mAh Battery, Charger, SD-Card etc >500,- € in DL
  • Yaesu FT1D:          5W Dualband, Modes: C4FM / FM, 1800 mAh Battery, Charger, SD-Card etc >300,- € in DL
  •  

Still my favourite toy....my lovely ID-51A

 

How should the settings look like? (Examples)

This example shows how DL6EAT (see "MY" entry) works with an Icom ID-51 via the repeater DB0EAT-B on 70cm. Make sure the "UR"-field shows CQCQCQ and "MY" shows your personal call sign. Then use one of our repeaters and press the PTT twice for one second each. The repeater will answer twice with a double-beep. Now please check the fields "R1" and "R2". They should now display the repeaters callsign. Check also if "R1" shows the mode (like B above) and also if "R2" shows the "G". Without that "G" you will not be forwarded within REF006C (and also not to others).

If you will not be auto-setted, you can certainly edit "R1" and "R2" manually. Make sure the letters "B or C" in R1 and also the letter "G" in R2 are on position #8 (last possible entry). So if the repeater's call has just 5 letters, like DB0IZ you need to add 2 spaces. (see example below)

Here is another example how those settings would look like for DB1XYZ working via DB0DMB on 2m (mode C):

UR:CQCQCQ

R1: DB0DMB_C

R2: DB0DMB_G

MY: DB1XYZ

And here is DK1ABC operating via DB0IZ on 70cm (mode B):

UR: CQCQCQ

R1: DB0IZ__B

R2: DB0IZ__G

MY: DK1ABC

Once again, make sure your personal Callsign has a proper and valid US-Trust registration. This is all you need - you are ready to go!

 

Important Note - or - how to fix a big ICOM bug:

All Icom radios can not simply be used in D-Star while in Simplex Mode while operating any hotspot or repeater as they don't allow you to program RPT1 and RPT2 while you obviously left repeater standards (no shift any longer)! Here is how to use this in Simplex mode anyway: (Especially necessary for Hot Spots)

Some transceivers, like the ID-51, ID-5100, ID-880, IC-2820, IC-9100 allow to enter the correct settings - and display them correctly when double checking, but believe it or not: They will still not transmit them! (There is still nothing in the related RPT1 and RPT2 fields - all empty) So please act according the following workaround:

Set repeater offset to minus and change the value to zero. Store everything in a free memory and it will work all fine!

This "Simplex Workaround for Hotspots" is mendatory for all known ICOM D-Star Transceivers (handhelds, mobile and base stations):

If you intend to use any simplex hotspot or simplex repeater please program the required frequency and set the repeater offest to "minus" (your display will show "-" now). Then program the value of the repeater offset to 0,000 MHz! Actually now you are using simplex again. Now you need to program RPT1 and RPT2 as requested or required. Finally do not forget to store your settings. You are now ready to operate reflectors...

Good luck!

 

How switching between different reflectors?

Well, there are basically 2 ways doing this. First is DTMF - the other is via the UR-field in menu "Call Sign"

Here is a short listing how getting around:

For D-Plus (US-Trust) - example REF006C:

  • Via DTMF: *6C   (Type "* (star)" followed by reflector-number and module)
  • Via UR: REF006CL  

For DExtra (X-Trust) - example XRF747C:

  • Via DTMF: B747C   (Type "B" followed by reflector-number and module)
  • Via UR: XRF747CL

For DCS - example DCS001C:

  • Via DTMF: D103   (Type "D" followed by dedicated room-number - check www.xreflector.net)
  • Via UR: DCS001CL

You can's get connected to certain reflectors? You may need to update your related host-files. In case of problems do not hesitate to contact us.

 

Here are the best external modem devices - as of our opinion:

This "Blue DV-Dongle" is pretty nice for travellers. It just needs a notebook and a simple USB-cable (no external power). This allows you to participate and work via D-Star world-wide and in all nets. The sound-card of your notebook is your voice-interface. You can use this also in countries where you have no operating license since you are not transmitting. (Pure internet-based)

My Opinion and Test Result: A clear "Must Have"!

Note: The glas-housing shown above (and below) is an extra, sold on Hamvention in Dayton, 2013. (Also available now from HRO)

This "Red DVAP-Dongle" is pretty nice too. Coverage is up to 1.000 foot on 2m or on 70cm. (Yes, 70cm version is available as well) You will need a PI or notebook and a D-Star handheld (like ID51 etc). All reflector changes (all nets) work wireless via your hand-held (as on real repeaters). Ideal for your house or your rental home/motel/hotel during vacationing or travelling. Some people (like myself) even use this along with a 4G modem in their car and work D-Star mobil from anywhere. (where GSM-coverage is provided)

This is the easiest way to become "online" with your handheld - even when in a remote location!

My Opinion and Test Result:  Highly recommended and still in daily use!

Note: You can't order this toy in Germany since CE-mark is missing. Owning and operating is legal - distributing and selling in EU isn't. The glas-housing shown above is an extra - sold on Hamvention in Dayton 2013. (Also available now from HRO)

 

This is an early Raspberry Pi 512MB with Dutch Mega hook-up - here shown as a 10mW Hotspot at Jan's Qth (DO1HH) in Sehlendorf. Jan told us this is working terrific and first tests are just surprising and promising. The whole tool was available for about 150,- Euros as a "WiFi connected 70cm stand-alone Hotspot". First test showed coverage of up to 6 miles by using an external antenna! Not bad so to speak.

Order info of the DV Mega boards for Raspberry PI Radio hotspot:  http://www.dvmega.auria.nl/

 

Here are 4 more pictures of latest DVMEGA hotspots with Pi 2B (4 core / 900 MHz):

The version below shows the dual band 2m/70cm version - this module costs a couple bucks extra but it's worth it:

 

This is a completed dual band hotspot based on a PI 2B (Note: Frequency and band is switchable from your handheld):

 

And here is a very nice fully shielded version of Jan, DL2HBJ:

 

This is how the cheaper mono band module (70cm) looks like:

 

Last but not least - here is another project which took me about 2 hours time. See the RaspBerry Pi B (version with 700 MHz dual core and 512 MB) bundled with the red DVAP-Dongle generating solid 18mWout on 70cm. Power is provided by a Logilink cell phone charger battery (the black box on top is a powerful LiPo Battery with 6.000 mAh incl. digital read-out!). This hotspot is connected via the LTE/H+ (4G) Network via my smart phone (Samsung Note 3) using the tethering function. REF006 is now available from anywhere in the world.....either via WiFi, cable or via LTE/H+....all your choice... 

It is even a perfect independent hotspot for your car! No switching of repeaters any longer - just stay connected!

Total cost of this unit is less than 100,- Euros excl. the DV-AP. A very good and cheap alternative to the DV-AP is the Dutch DV-MEGA-board which fits right on top of the Raspberry. Total cost incl. battery is around 190,- Euro then. The picture below shows my personal 70cm mobil hotspot based on the Pi + and the DV-AP-Dongle.

You can either use  the "Maryland-DStar" - firmware, available here  http://www.maryland-dstar.org/ or the "D-Star Commander", available here: http://w6kd.boards.net/thread/2/dstar-commander-public-release-download/ (We preffer the D-Star Commander)

My opinion: The "D-Star Commander" offers a much better GUI, auto-update including all host-files and a more stable WiFi-interface. Also it comes with a G3-option in optimzed versions (DV-AP or DV-Mega). Just a headache-free solution for both external boards.

 

The "red" DV-AP Dongle with Raspberry B+ (Dual Core @ 700 MHz) and 6Ah rechargable LiPo battery pack:

 

Bob's (W6KD) latest Linux version of the "D-Star Commander 2.0" based on Western D-Star and Jonathan's (G4KLX) S/W (Different versions available for DV-AP and DVMEGA):

 

 

Here is the brand new BlueDV. On top you find the well known DVMega. Designed by David, PA7LIM - order info: http://www.combitronics.nl/index.php?route=product/product&product_id=61

The Blue DV doesn't need any PC or Pi - it works totally independent and can be controlled from your cell phone via Bluetooth or alternatively from your Windows PC - great!!! It supports D-Star (all nets), DMR Brandmeister, DMR Plus and C4FM right away. Switching between modes takes just seconds...

Radio Mods - How optimizing filters for D-Star usage:

And here are some pictures of a modified FT-8900 (normally we use the cheaper FT-7900). Anyway - as you can see below, we installed 2 x 6 KHz-filters for D-Star - and 9 KHz for FM-N. Most of the Yaesu-Transceivers come with 15 KHz-filters and just reduce deviation to comply with FM narrow. The RX bandwidth stays at bad 15 KHz...

One of my next projects will be the FTM-400D. This unit uses 15 KHz filters still in both FM-modes (FM and FM-N)......this is next to worse!

 

Some digital history - how we started our D-Star Net back in summer 2012:

In the afternoon of July 30th 2012 "DB0EAT-C" went on air - a D-Star Repeater and Hot Spot - no voice in FM. The first step was a 2m hot spot - operating on 145.575 MHz simplex. And yes, DB0EAT-C became Schleswig-Holstein's first 2m D-Star Machine! Today, 2,5 years later it has a 12,5 KHz license and operates with 600 KHz (-) shift.

DB0EAT now also provides another full duplex 70cm port. TX is 438.400 MHz (-7,6 MHz). Both repeaters have been approved by the "Bundesnetzagentur" in June 2012 - the equivalent of the American "FCC". Since April 2012 we all got new band plan regulations; on 2m the former FM-frequency 145.575 MHz turned into FM-narrow and DV usage only. Please note: Licensed DV repeaters enjoy priority over any kind of analog voice operation! So please no FM voice on this frequency in our area.

DB0EAT found its home on my 70 foot tower. Total height is 80 foot (max) above ground, about 120 foot above sea level (Yes, we are just a couple foot above sea level at my place!) BUT, the tower is a self supporting crank up tower and I am living in a pretty windy place just about 30 miles off the North Sea coast (Atlantic). So most of the times the tower is down to about 53 foot above ground only. Anyway, coverage is still reasonable - at least on 2m.

Our Goal:

Only wireless accessability to the D-Star network will attract people. Pure Internet-based participation is not satisfying most of us. Aren't we all about wireless? My personal goal is providing coverage all over Schleswig-Holstein (our tiny county) by having smaller cells - no big guns and no DX repeaters on radio station towers etc!

This concept will cost more time and money but provides way more flexibility in the long run. Remember each cell can also work independent (as known from the "old" analog repeaters) but can also become part of most reflectors.

 

About the Software:

All our repeaters use Jonathan's G4KLX-Software - no specific hardware for coding or de-coding. All software based and all on Windows XP Pro. IF you are interested in this opportunity please visit the following two Yahoo Groups. Please be aware that you need to be registered before you can access them:

And here is North-Germany's highest mounted WebCam, "live & online" since Monday, December 8th 2014. This camera shows a live stream and turns roughly 225 degrees. It also shows the old German submarine U-995 used in World-War II. Our repeater antenna is rougly 2m higher than this cam - same place.

I finally got the order to bring this HD Cam on fast 4G (LTE) internet. The uplink speed is >35 MBit now, provider is Deutsche Telekom.

Click here to visit the official website of "Deutscher Marinebund" and view from this location now:

The following two pictures were taken on March 25th 2013 from top of the monument - not the right time for any outside work! This first one shows the lovely Kieler Foerde - view to the west. Kiel (our capitol) is visible on the horizon on the upper left corner - distance to Kiel is 10 miles.

 

This one is the view to Fehmarn island - to the east. Note all the snow down there - spring did still not arrive end of April!

 

Antenna installation on May 14th 2013 - Picture shows Juergen, DG4JC while mounting Procom CXL 70-5C/l and WiFi dish (Our first installation for 70cm only). Later this changed to one dual-band antenna (also Procom). This antenna worked excellent on 70cm but we decided to use just one antenna for both bands later. So 70cm fall down a bit (-3dB) but 2m over-compensated this pretty well. Now DB0DMB is active on both bands. See latest pictures of our today's Procom antenna on top of this website.

 

Estimated coverage - for base stations. Note: The purple part will be not much useful for D-Star! This is DB0DMB-B 70cm

 

And here is 2m for base stations:

 

This is how DB0DMB looked at the beginning (70cm only in 19" Rack with glass door):

 

DB0DMB-B and DB0DMB-C as they look today: (January 2014 - now with 2m, LTE internet modem and server & client all in one box)

 

Kathrein 6 cavities 2m duplexer and Procom diplexer in place:

 

Juergen (DG4JC) during 2m installation back in December 2013:

 

A new Procom Diplexer got installed - here under alignment:

 

Antenna now up and running - Do you see the white stick on the upper left corner? (Note: This was our first antenna-location. Today it sits on the eastern end of the cage)

 

Visibility from DB0DMB on a very clear day - the half moon over the water is the Fehmarn-Sund-Bridge in a distance of 35,6 miles = 57 Km. Interesting though - Fehmarn Island is not visible - it is already under the horizon. This photo was taken on November 23rd 2015 by Michael Nitz by using his professional Canon 7D and a 768mm lens. Many thanks Michael!

The lookout towards the north-west (Neustadt and Grömitz):

 

This shows the nice coverage of DB0MAR-B on the north-west corner of Fehmarn island. I had no problems to operate via DB0MAR even in a distance of 41 miles (66 Km) with my ID-51 and it's super small rubber duck antenna as you can see below. It also worked well with 1 W only. DB0MAR came in between S3 and S6 right on the beach!

    

 

Itzehoe, DM0IZH:

This is our location in Itzehoe - the repeaters (DM0IZH) found their home on top of a flour mill - 51m (170 foot) above sea level:

How it all started - a lot of pre-work:

Re-modeling a 12 chamber "Huber+Suhner" duplexer. Some of them need to be modified before alignement and calibration. The pictures give an idea of all the mechanical work and the inside view. All holes have to be drilled - different for RX and TX:

What is a Trial & Test Repeater (An example - my # II under construction)

Well, I heard this question pretty often and will try to answer this. Basically I built a portable repeater - all in a single handy box which can be carried around and which allows flexibilty and portability in order to try different locations and assist those of you who want to build their own machines, By having a working sample it is all way easier. The following pictures show my trial & test repeater #2. The pictures may give you a rough idea how such a system looks like - all the hardware is visible. Some of the pictures have been taken w/o annoying cables. Total cost of this full duplex repeater (depending on where parts have been purchased) is around 750,- Euro. (w/o work - parts only)

 

Again, all repeaters can be unlinked from their home reflector and then linked to individual repeaters around the world. DB0EAT has been used and successfully tested as a link repeater to the San Francisco Bay area. The linked repeater was WW6BAY (often part of REF014). WW6BAY is a wide coverage repeater overlooking lovely Palo Alto, South Bay, California.

Please feel free and give our new network a try! DB0EAT-B, DB0EAT-C, DB0DMB-B, DB0DMB-C, DB0DWL-B, DB0IR-B, DB0IR-C, DB0HCC-B, DB0BUX-B, DB0MAR-B, DB0IZ-B, DB0IZ-C, DM0IZH-B, DM0IZH-C, DM0HEI-B, DM0HEI-C, DM0HHW-B or DM0HHW-C will welcome you! All of them are "up and running" right now. Any feedback and/or your opinion is much appreciated via admin@xrf787.de

Our young new reflector "Schleswig-Holstein - NorthStar XRF747 and XLX787" ia growing rapidly. Today we have  often more than 30 repeaters in our net!

 

Note: I will publish further updates and changes as soon as they come along here on www.qrz.com/db/DB0EAT. Check date of last changes on top of this info.

Many thanks for visiting DB0EAT on qrz.com. See you on XRF747 and XLX787 via D-Star - have fun and enjoy!

Vy73,
