Raspberry Pi Forums

Hi all having just recieved my Pi and being interested in ham radio is there any radio related Pi projects going on?
Sdr would be a good start.
Im President of the Tablelands Radio and Electronics Club in Far North Queensland and there are a few of us in the club that have an interest in the Pi, and I will be looking for a club project for us to work on!

Any info would be apriciated we were all beginers once.

Cheers

The repository or 'repo' (programs available for download for the Pi) has an entire section entitled 'ham radio'. - use a package manager like 'aptitude' (already installed on the Pi) to look through/download what's available.

Unfortunately the Pi doesn't come with an audio input, so a lot of the sort of thing you might be interested in (Morse and PSK31 communications and so on) won't run on it without some sort of audio input add-on. But you'll probably find a few things like antenna design programmes which can be used straight away.

Yes, there are projects out there.
Xastir does work under Raspbian (wasn't able to view imported maps).
Dixprs also runs.
There are RF to internet IGates up &running.
I'm planning a stand-alone APRS tracker (Pi plus GPS, with afsk tones I/O to existing rigs).
Problem is no audio input - P5 connector not yet populated for this
Haven't had much luck with USB soundcard, need 'soundmodem' package working, but cheap USB soundcards have both died

There have been a few short articles in RADCOM, the magazine of RSGB.

I encountered a nice full screen APRS tracker on the internet, and managed to get it up and running in an evening. The website is located here http://www.danplanet.com/blog/2011/03/2 ... al-screen/ and on my own website http://www.pa0esh.nl/index.php?option=c ... Itemid=106, you can find a more less detailed description how to get to end result, including a movie I shot of a working product handling a very broad from direct from the internet.
I purchased for less than 30 dollars at DX a tft wide screen meant for automotive purposes which handles the RP's video and fits nicely in the car. The TNC is still a TNC-X which i will change for an OT+ SMD tracker, or even better, a soundmodem TNC.

Wow - it's almost like you read my mind.

I was putting this low cost (high value) solution together which interfaces to the Rasberry Pi (we're calling it the RD3). It is basically an FPGA with a high speed DAC and a high speed ADC. At first we're putting some simple applications on this platform : oscilloscope, signal generator, logic analyzer, but we were planning on a Software Defined Radio application later.

The ADC and DAC will be 8 bits of resolution at 100 MHz (after some feedback from this forum, I discovered there is interest in a 10 bit ADC at 65 MHz for a higher price, so we're planning to do an "A" version to support this). The FPGA itself is a Cyclone 3C5 (5100 Logic Cells, 23 multipliers (18x18), 46K bytes of memory). We picked a package which allows us to upgrade to the 3C25 (25K logic cells, 66 memories, 66 multipliers) if there's a demand for it.

Connect it up to a radio module, and you can do your own SDR.

The FPGA gets it's configuration file from the Raspberry Pi, and we're planning on communication via SPI interface.

Here's two links to what we were planning :

Right now, we've sent out for some PCB's to be fabricated, and we'd love to hear any feedback.

(I'm seeing if I can get our web master to do a registration link so we can let interested parties know about our progress. I'll post a link once we get it going).

Best Regards,

Tony

Hi there
Saw that you used info from my website. I have just updated the story since i have build now three different ham projects , ie aprx, dixprs and the dantracker on a Raspberry, using both sound modem as well as normal KISS / AX25 modem.
All three projects now work without problems... Especially the DanTracker with N7NIX branch solution is really nice.
Hope my info helps.
