Hi and 73!
My interest areas in the radioamateur world operations are all phone modulations DX modes, CW*, digital modes, SSTV, ATV, telephony QRP and telegraphy QRP, meteor scatter, Moon reflection (Moon Boucing EME), satellites, amateur radioastronomy and im active in all that areas.
*(Pse, do not work CW morse code with me with MGM, the same is to say, pse dont use Machine Generated Mode computer software to work CW coding and decoding morse code with me. I think CW should be worked with vertical, iambic or bug manual or semi-automatic keys, not with digital modes computer software for God sake!)
At this moment im transmiting in HF bands with Kenwood TS-2000, Kenwood TS-870, Kenwood TS-450S and Yaesu FT-857D. Conected to these transceivers i have my 8 HF bands (from 6 meters to 40 meters including WARC) home made cat´s mustache fan dipole, a set of 6 half wave length dipoles conected to the same feed line with a balun 1:1 installed inside of the attic (loft) with 10x10 meters and 2.5 meters tall of a building with 3 floors high.
On VHF and UHF im transmitting with my home made indoor (inside the attic) yagi dual band with 5 elements on VHF and 10 dBi´s and 8 elements on UHF with 12dBi´s.
I use more this antenna for satellites and moon reflection EME JT65 digital modes as well JT65M and FSK441 for meteor scatter. It is attached to my 2 home made VHF and UHF 20 dB´s LNA RX amplifiers specially design for moon reflection and meteor scatter operations. Excelent results on EME moon reflection on digital modes and meteor scatter and sure as hell excelent results working DX in SSB and FM phone direct :)
Other antena i am using for the VHF UHF bands is the VHF UHF dual band diamond X-50, a vertical isotropic ground plane antenna installed also inside the attic like all my antennas are.
I am working CW Morse Code now with the Hi-Mound MK-705 iambic dual paddle key with marble base in the left image loaned by my friend french ham Thierry F5SIB.
I also work CW with the recently acquired MFJ-564B iambic dual paddle key as you can see on the right image. Also a very good CW key for the relation price/quality. Very soft the paddles ( it feels like the piano keys :) ) and a very heavy and steady metallic base. It does not go anyware whyle you key :)
Watch the video in youtube site:
Pse, click on my HRDlog.net map for larger view and then click on the rounds, squares and triangles modes to see the call sign of the DX QSO and DXCC date and hours and other infos of the qso´s i had done.
Other huge passion i have its in amateur radioastronomy. Im an amateur radio astronomer working the fade received radio signals of the sun and the Low and Short A and B level radio bursts of jupiter´s magnetosphere, meteor scatter, electrical lightnings of all around the world, amateur SETI in the hydrogen line and also scattering the hydrogen line cosmic background noise radiation in the microwave region of RF spectrum.
My actual project is one of the more hard to achieve from all radio astronomy projects i´ve been done: The reception with an home made radiotelescope for the 10 Ghz RF spectrum region to receive pulsars RF emissions. (the construction of this receiver with the cooled compressed freon gas low noise -7º celsius with a 3200 Kelvin temperature 20 dB´s pre-amplifier and parabolic dish are actually in working progress.)
The parabolic dish will be actually 2 reflectors (one main and a second concave ellipsoidal reflector gregorian system to achieve an aperture gain eficiency over 70%).
I will finish it in the next 2 moths i hope :) Maybe i will test "the first light" of this new radiotelescope lestening to the beating of the pulsars in March or April of this 2013 year :)
At the same time i am doing this radiotelescope receiver, i´m gathering some schematics to start to build a QRP transmiter with 1 watt e.i.r.p. power for the kilometric band (2222 meters) to work from 135.7 to 137.8 Khz frequency on CW, QRSS (for the very slow CW to extract with a computer sound card and special software characters from below the audible noise floor) and 200 HZ narrow band digital modes.
Imagine the head hake construction for the antenna to work on this band!!! :)
And now that in Portugal, we receive the good news from ANACOM about the new Ham band of 630 meters alouded for the Extra Class (Class 1) Advanced Class (Class A) and General Class (Class B), i am considering in build this kilometric transceiver including also the 472 Khz - 479 Khz.
Untill then, i insert here some results in spectroscopy and spectrograms of my homemade radiotelescopes.
The next image below its one of the first radioimages of asteroids i´ve done using the hybrid technic of doppler active radiotelescope radio wavelength emition combined with virtual computerized colorization. So this means that this image its a virtual radio image of a celestial body, in this case, the Asteroid TU 24 with 17th days of exposure resulting from the emition of radiowaves from the arecibo radiotelescope.
The doppler radio waves transmited by arecibo were then reflected by the asteroid and then received by my radiotelescopes and with all the raw data i rebuild line per line the variation in S-units with a simple linear scale programmable database from 0 to 9 intensity and A to I in color depth.
Since i was unable at that time to receive the true variation in time of doppler radio waves trasmition, i lost a lot of resolution.Therefore i had to rebuild an relative reading of raw data acording to variations in shape and size magnitude of this celestial body (with normal variations in phase incidence angle etc etc)
Anyway, it was a good experience and a great school to the arts of technic of radio emition and reception for me at that time.
This image would be impossible to see with visible wavelengths (light) because this type of body dont reflect almost any quantity of visible light, therefore, using the radio wavelength its the more possible technic to observe this kind of dark celestial bodys.
The next image below, its a screen shot of the spectrum lab, a spectrogram software that runs in windows operating system enviroment.
It is a spectrogram of other of my radiotelescopes for the meteor scater or meteor reflection.
The principle its very simple. In fact, it can be one of your first radiotelescopes exacly because you dont need very complicated antennas neither very complicated receivers and software.
This one was made tuning to a vhf taxi central call of spain with my homemade 3 El yagi antenna with an 20 dB´s amplifier beamed to barcelona region.
When a Leonids meteor shower passed trough Earth and some entered in our atmosfere, due to its speed, angle and mass, it started an ionized layer all around the meteor.
These ionized layer of atmosfere around the meteor reflected the radio signal transmited by the taxi central call of barcelona,
Of course, i received that signal with my rigs and this spectrum lab audio spectrogram.
The results are seen in the picture as falowed:
(and yes, of course i eard the signal in my radios :) )
I also participate in sharing the meteor counting on the radio meteor observatory site. I am the first Portuguese radioamateur and amateur radioastronomer in this project and that i am aware of it the only one untill the present moment i write this in 22-05-2013. Pse go here to see hourly updated live infos of meteor countings from my radiotelescopes and click in the unique balloon in Portugal. Thats me:) :
My radiotelescopes works with FFT and DSP spectrograms like Baudline for mac, DL4YHF Spectrum Lab and HROFFT for automaticly count the number of meteor events.
I already share this meteor countings in the 2005 in the radio meteor observatory site, but then i leave the project.
I think i will restart the project agn :)
The G.R.A.V.E.S. (Grand Réseau Adapté à la Veille Spatiale) French militar Radar located in Dijon. The carrier of the Radar at VHF in 143.049.750 USB and 0.780 Khz audio frequency received by my radiotelescope.
The vertical trace at 1424 UTC covering all audio frequency in the total bandwidth in the HROFFT spectrogram its from electrical origin of some kind (electrical lightning, sparks of combustive engines, neon and fluor bulb starters and so on. This list of RFI, QRM and QRN never ends :) )
Another interesting spectrogram with the DL4YHF Spectrum laboratory spectrograph software. The very fade pulse echoes of G.R.A.V.E.S. radar at every 5 seconds over the 0.750 Khz audio frequency carrier region at 0.900 Khz.
G.R.A.V.E.S. Radar radio signal reflected by ionized meteors at 0.960 Khz of audio frequency at 143.050.00 Mhz. The doppler echoes were then counted by the HROFFT software resulting in a total amount of 5 meteors.
you may watch a video of one of my radiotelescopes detecting a S-Burst of the magnetosphere of Jupiter:
In these 2 animated Gif´s you can see how Jupiter´s magnetosphere with the IO orbit redirect the RF signal to Earth.
I like to use Radio Jupiter Pro for the radio storms predictions.
Here some exemples of L and S-Bursts of Jupiter´s magnetosphere
I detect also the Solar wind Bursts on my 15 meters radiotelescopes.
And here an exemple of a Milky Way Galactic RF Noise also detected at 15 meters band.
I like to lesten also the Ionosonde RF "Chirps"
HF CODAR Radar detection for the measurement of the size of the ocean waves.
My seismic earthquake detection with my Sudden Motion Sensor of my macintosh computers.
I know all the time when it hapen an earthquake :)
And this are the WEFAX of NOAA 18 weather fax satellite images received by my station in last year of 2012.
Lately i am not doing more the reception of NOAA WEFAX satellites family.
I have so much activities in the radioamateur world including satellites and Moon Bouncing EME that reaaly i dont have time for it.
But soon i will receive some more.
And this is the software i use for my Macintosh computers for Satellite tracking and control of azimuth and elevation rotors, the MacDoppler:
One of my future plans is to develop a radiotelescope doppler RADAR system to search and visualize the asteroids orbiting our solar system:
And this is the TS-870RC app i use to control my Kenwood TS-870 with my mac.
And this is the Morse Code Machine software for windows developed by my friend Bruno Ramalhete to help radioamateurs and non radioamateurs learning Morse Code. I am the Beta Tester for this software. You can click on the link of the Bruno Ramalhete blog to read more about it and instructions to download the software : http://www.pceconsolas.blogspot.pt/
This is the last updated version at the present date of 26th December of 2013 from Bruno Ramalhete developer.
Stay tuned, i will put more images of my radiotelescopes analysis, and also more pictures of my home made antennas and electrical home made circuits.
I like to build my own antennas and electrical circuits.
I build all my systems at 21 years.
My last three electrical homebrew circuit projects i´ve done were the satelite interface tracking device, a receiver for the 15 meters band with GasFet pre amplifier of 20 dB´s to receive the very fade signals from the jupiter´s magnetosphere as well sun proton emissions and a VLF receiver for the kilometric RF spectrum region to receive the radio signals from all the lightnings around the world.
My 3 last antennas i´ve been built were the Cat´s mustache fan dipole, an antenna to work in the 10,15,17,20 and 40 meters HF band also 6 meters with the 3rd harmonic of the 17 meters dipole element installed inside the attic (loft) with an area of 10X10 meters square and 2.5 meters tall of an 3rd floor building, a portable dual band VHF UHF yagi with 6 elements for satelite field operation with portable VHF UHF dual band transceivers with a relative gain of 8 dBi in UHF and 6 dBi in VHF and an umbrella parabolic dish with 3 meters diameter (20 dBd) for the amateur SETI to work in the 1.4Ghz spectrum region.
I wrote a breeve summary of my station below this 6 pictures:
My station at November 25 of 2013. Now beyond the 2 main tables with all my rigs i have 2 more tables, one on the left side for electronics homebrew electrical circuits and antennas and the other table on the right for papers, documents, radio parts and acessories as well other notes related with the hamradio world :) It is now a dedicated room for shack :)

Here you can see some detailed pictures of my station:
This is my brand new "Star" in my shack: Transceiver all mode all band Kenwood TS-2000 bought at (3 hours ago ah ah) 10th July of 2013 :)
Pse watch the video on youtube here: http://www.youtube.com/watch?v=lQ1MdRFXq5s
This is a picture of my shack on 19th July of 2013. I need to buy a new chair and table :)
Pse, go here to see my Ustream live video and audio streaming of my radioamateur activities
wow well, now that i am sharing my shack with you, i will share also a picture of my 2 electrical compounds box. Its a main and vary important part of my radioamateur activitys to build my homemade electrical circuits so therefore its an important part of my shack :)
And this is the table with the tools to build my homemade electrical circuits:
A detail of my VLF receiver construction here in a bread board for testing the dual Op. Amp. electrical circuit configuration and to detect some over reacted signal to noise ratio or other kind of RFI and noise figures. Of course, at this stage, its far way from being finished:
Already in the PCB working progress of welding the electrical circuit compounds with all the variable resistors and switches hung :)
And the next 2 pictures are a detail of my VLF radio telescope receiver PCB totally assembled to work on the 15 Khz band.
You can see the variable resistors to control the OP AMP RF gain of first stage and AF amplitude of second stage as well the headphones :) In fact, this radiotelescope receiver can work like an walkman in portable receiving operation:
And in the next picture, the PCB VLF radiotelescope receiver already with the crocodile wires conected to PCB ground and antenna terminals. Here the PCB was conected to the Computer for testing the "first light" to analyze and search for the harmonics RFI to see if all its in normal standards for this type of RF OP AMP amplification.
And here, the VLF receiver with all electrical compounds including variable resistors mounted in the PCB.
The "first light" of this radiotelescope for the VLF was trully a huge success!!!
I receive the first "sferics", "tweeks" and "whistlers" now using a much better headsets. I felt happy with the results as a young child after receiving a new toy!!! :)
This is my homemade rewired portable Bar Antenna for VLF to work on 7Khz RF spectrum. In fact it works as a E-Field Probe.
A tipical spectrogram of my homemade VLF receiver with a relative strong "whistler" at the same time with "sferics" on the 5 Khz VLF RF spectrum region.
I will put here more spectrograms of my VLF radiotelescope everytime i have good signal readings.
And this is my homemade regulated DC power suply for testing my homemade electrical circuits with its primary and rectified, anti-ripple filtering and regulated voltage circutry:
And this is an old Reace RF power and SWR & modulation tester meter for the HF high bands short wave but i am preparing it to work also on the 630 meters band and also on the 2000 Kilometric band. I said also, exacly becasue i dont whant to destroy its hability to mesure on short wave band as well :)
Here are pictures of some of my homemade antennas. I will insert here soon a lot more pictures of my homemade antennas as well some more electrical home made systems and electrical circuits:
Homemade Portable VHF 2el 6dBi UHF 4el 8dBi for field Satellite Yagi
Homemade UHF Yagi 8el 11dBi
Feel hungry? Or the need to TX and RX in 2.4 Ghz? Why not doing both things at the same time? HI HI HI :)
This is my homemade (Can) tenna ( antenna made from a can ) to work on the 2.4 Ghz RF spectrum region.
I build it in 2009 but i made some changes in the driven element and in the directors. Now (2013) it has more gain and a bigger bandwidth.
My homemade huge 1.5 meters portable wip antenna for 10 meters band in my Albrecht AE 2990 AFS with the green 2.5 meters ground wire attached to the PL plug.
With the Albrecht AE 2990 AFS and this antenna i already make some contacts and qso´s on 10 meters New York repeater in FM on 29.620 Mhz only with no more then 2 Watts that is the power of this radio with internal batterys!!!
It is still a portable antenna HI HI :)
A detail of the reductive coil. The whole wire inside the antenna structure mesure 2.5 meters including the spiral turns of the reductive coil.
Here is a detail of the 2.5 meters ground wire for the 10 meters portable antenna pluged to the PL ground.
Homemade VHF 5el 10dBi UHF 8el 12 dBi Yagi.
And where are all my homemade antennas?
They are not on the roof!!! :)
The only ones you see there are the TV WFM VHF UHF common antennas:
There they are! :)
My homemade mustache cat dipole to work from 40 meters to 6 meters band including all WARC installed inside the attic in a building with 3 floors high along with my homemade ground plane isotropic VHF UHF dual band antenna.
It is installed already at one year. As you can see, a spider already decided to make her own house in my homemade mustach cat dipole HI HI :)
The following image is a detail of my homemade recoiled balun 1:1 with low oxigen coper to decrease the losses.
Also all the wire band elements of this mustach cat dipole are made of thick 6 milimeters low oxigen copper, once again to avoid more losses.
here is a detail of how elements are installed in the wood roof structure:
And here is a detail of the reductive coil for the 40 meters band becasue i have only 10 meters of attic. It is important the quality of this coil to maintain proper electrical wavelength and proper ressonance with reduced physical length:
And this is my homemade vertical ground plane dual band VHF UHF with 4.5 dB on VHF and 7,2 dB based in the model of Diamond X-50.
I build it with pieces of other ham broken antennas and PVC pipes. The active driven element is made of low oxygen multiwire copper streched inside the PVC pipe shell and fixed to the edge of the PVC pipe.
Whitout any problems it received signals of 59 and put TX signals of also 59 in phone SSB in france germany Italy UK etc in sporadic E propagation.
And this is a detail of the base of this antenna. Becasue it is not on the roof and away from strong winds it isnt fixed to the ground.
So i used a plastic base prepared to be filled with water to increase wheight in center of gravity:
I will put soon more pictures of my installed homemade antennas in the attic.
And this is my commitment and contribute to space scientifical research and odissey :)
