<DIV>I am definitely interested Martin. After I straighten out a few
things, I can do both the LF and RP. Right now, I have so many different
versions of PowerSDR and Quisk on so many computers, it’s hard to keep
track!</DIV>
<DIV> </DIV>
<DIV>I am glad that you are taking charge of this! The Red Pitaya is
definitely a wonderful SDR platform. I wish the HPSDR guys would get more
interested in it, as I think the RP platform would be better than the present
Hermes Lite. Of course, the RP costs a little more, but look at what the
hardware can do!</DIV>

<DIV dir=ltr>Thanks to Pavel Demin, the Red Pitaya now has a couple of SD card
images to support a wide array of interesting and useful software.
<DIV> </DIV>
<DIV>There's a <A
href="http://pavel-demin.github.io/red-pitaya-notes/sdr-transceiver-hpsdr/"
target=_blank>dual receiver single transmitter</A> configuration that acts like
a HPSDR network interface with dual receivers and a transmitter. This
opens up the possibility of using PowerSDR, Quisk, an Android app or other
software. It seems like diversity reception works in PowerSDR.</DIV>
<DIV> </DIV>
<DIV>
<DIV>I'd like help design and build the rest of the stuff it takes to turn the
RP into a robust, portable transceiver. I've never done this before and
hope there's others on this list who would be interested in joining me. We
have some great resources in the club although I know everyone is time
constrained. I'm willing to commit significant time and effort to the
project.</DIV>
<DIV> </DIV>
<DIV>
<DIV>I realize there's time sensitive work going on in the AMRAD Low Frequency
world. That said, I'd like to propose this as a AMRAD project to follow on the
Charleston receiver as time permits. As most of the digital heavy lifting
has been done it's mostly a matter of building the analog transmit/receive chain
and ancillary stuff. </DIV>
<DIV> </DIV>
<DIV>Terry N4TLF has done testing on the RP LF performance and found it too
noisy to be useful but perhaps there's a fix. </DIV>
<DIV> </DIV>
<DIV>The <A href="http://store.redpitaya.com/red-pitaya-board.html"
target=_blank>Red Pitaya</A> is now $238 so an affordable, complete HF SDR
transceiver should be possible. <BR></DIV>
<DIV> </DIV>
<DIV>This could be a great project for the club that hopefully attracts interest
and new members. </DIV>
<DIV> </DIV>
<DIV>So - anyone else in? What do you think?</DIV>
