<font face="Comic Sans MS">Interesting little gizmo. I'm
concentrating on flying machines these days, so I don't want to
get diverted. <br>
Looking at it though I think that little board has potential as a
payload. I have a pretty good imagination, but my programming
skills are almost non existent.<br>
A simple ham legal thing that might be fun would be an airborne
cross band repeater or perhaps transponder. Would that be hard to
implement?<br>
Fox hunting? Radio surveying? Dang that's a pretty cool device,
wish I were smarter and younger...<div><div class="h5"><br>

<div>As Martin said earlier, yes there are some people here
that are using the Red Pitaya, especially for the basis of
a nice SDR. I just received my second one today. For the
money, it’s hard to beat as an SDR building block. With
TWO channels of 125 Ms/s ADC and TWO channels of 125 Ms/s
DAC, plus other I/O, and a nice FPGA with embedded dual
ARM9 hardware cores (NOT taking up any FPGA fabric), it is
a pretty good device. HF diversity reception is one
interest, for example.</div>
<div> </div>
<div>I’m not sure that I totally buy into the “lab
instrument” usage, but for a quick-and-dirty device, it’s
also useful. Developed by engineers at CERN in their
spare time, it has a decent design and backing.</div>
<div> </div>
<div>Check out the blog at <a href="http://redpitaya.com" target="_blank">redpitaya.com</a> for more info.
There is also a Google Group for those interested in
pursuing the RP as an SDR, SDR-NET. I’ve not mastered the
“Google Groups” thing yet, but the interest there is
growing, with people from around the world.</div>
<div> </div>
<div>I have no connection with Red Pitaya. I just know a
good SDR block when I see one.</div>
