Red Pitaya SDR update

[Terry N4TLF]

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!

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!

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.   

There's a dual receiver single transmitter 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.

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.

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.  

Terry N4TLF has done testing on the RP LF performance and found it too noisy to be useful but perhaps there's a fix.  

The Red Pitaya is now $238 so an affordable, complete HF SDR transceiver should be possible.  


This could be a great project for the club that hopefully attracts interest and new members. 

So - anyone else in?  What do you think?
