It appears some members of the amateur radio are already excited. The potential for the Pi could only be limited by ones imagination. There are as many of you are aware many of the amateur radio programs are primarily designed for windows. Echolink, SlowScanTV(MSSTV), DigitalTV(Easypal),PSK31(MMVari). All however need a good soundcard, with mike input, linein, lineout, speakers out. It certainly would be interesting to see what could be developed/built on the scale started by the Raspberry Pi experimentation. Obviously the soundcard and software is the biggest hurdle for their use with the Raspberry Pi. Monitor and keyboard (mouse ?) input and output has been solved though I note VGA output does not feature on any model seen. Challenge as always would be initially the cost but I am sure their will be some experimenting amateurs out there, who have a better brain and steadier hands for construction than I and have more time available. My other use for the Raspberry would be suitable software and an USB plug in mini receiver for the new digital shortwave broadcasting DRM. To date such radios or software seem very expensive which again is one of those major challenges we all face in the development stages of any project. Just a few of my thoughts for the future. Be interested to read the feedback generated. Cheers and thankyou. 73.
