Not with the shield, but with the OpenTracker+. His designs are pretty good, but they're kind of a pain to work with. The Radio Shield looks better, but it's still not quite hackable enough for me.<div><div><br></div>
<div>This is why I'm working on an all-software APRS/AX.25/AFSK1200 modulator for AVR. The output stage is a 1b DAC: 2 resistors and a cap. It's working, but the code needs a little bit of cleaning up. <a href="http://github.com/jbm9/ArdPRS">http://github.com/jbm9/ArdPRS</a> . I haven't started on receive, mostly because it's not something we're currently using in Project Bacchus. It still has a few quirks (I think I know what they are), but you can see it getting into an IGate at <a href="http://aprs.fi/?call=kj6anm-11">http://aprs.fi/?call=kj6anm-11</a></div>
<div><br></div><div>AFSK1200 is trivial enough that there really ought to be a totally open/Free modem/TNC by now. I like Scott and his products, and appreciate his work (especially his excellent theory of operation documentation!), but it's time for the community to move past that.</div>
