Yesterday I had chance to have a small time to work on preamp.
After many modifications of my crane, my rotor and my pivot system, my dish is up.
I should receiver my last missing components for my 1420Mhz receiver (Hydrogen H1 line). I’m expecting an airspy, some SMA connectors.
I have also received my beaglebone black in order to create an USB over IP connectivity. I also received today my support for my source ! fast shipping from Franck of RFHamdesign !
Today Johnny Winter has left us with a wonderful blues heritage !
Photos are more explicit than a big speech :
photos removed due to server issue.
- Internet User access in Intranet and Station over SSH tunnel (IOS/Android/Linux/Windows)
- User take control on station server via RDP protocol (xrdp package). (over Internet or Intranet)
- Station is powered on/off via SMS on GSM band (in case of Internet failure)
- RDP server host all control tool plus mumble server in order to stream audio to remote location if needed.
The first task I had to work on was the CAT system with my ft817.
First I decided to install Hamlib (with Grig GUI frontend). Generally packages works well and it is easy to compile. This time it was also the case. Unfortunately I had to be able to modify the VOX parameter in order to be able to speak on local relays. It is not possible to do such action with hamlib.
My second option, in order to have some comfortable interface was to install Ham Radio Deluxe (the last free version) over wine. It worked quite well and if we do not want to use the digital program (I did not test the logbook) it is fully functional.
At the end I used also the wonderful FT817OS witch is a perl application that simulate an OS dedicated to the FT817. The job made is amazing and really funny to use. I did not finished to explored it but with a small API (netcat?) and a graphical it could be THE solution (http://search.cpan.org/~jrubin/)
At the end, my needs are in fact only be able to change freq, change power, switch TX/RX. All this can be done with all these tools.
Great no ?
After some quite long period I decided to start again an old school blog site ;-). Effectively I have been quite away from radio-ham activities. Reasons have been in disorder : Job, Child, Home (making), QRM generator by Lamps on street…
I always had on my mind the idea to come back to EME and to have a look on Radio astronomy. Now we are. I bought an Rfhamdesign 2,40m mesh dish kit… exciting.
In order to be a bit more technical (does it need ?) I decided to create my station remote. For so, all technical stuff has been removed from my shack and installed in a technical cabinet on the bottom of my tower. HF generator is a FT817 and it is piloted from a small linux box. I use for the moment fldigi for playing on HF (not really fun to be honest) and on 2m for listening satellites (more fun). I played also with funcube and Transfox SDR.
