Hi Frank,
after a long time of development and debugging I have uploaded today the latest version of user interface and my part of the Red Pitaya firmware for DiscoRed TRX.
The files can be found at github:
https://github.com/ted051/DiscoRedTRX

Best regards, Wolfgang

Hi Pavel!

Two questions from me:

(1) I run a WebSDR (160m.net) and would like to use the Red Pitaya (RP) board I have (125-14) as a front-end capture card to replace my rather odd collection of HF SoftRocks + analogue soundcards and also homemade up-converter and RTL dongle. Is this possible somehow? Of course, I would like to increase the frequency band coverage of my WebSDR by using RP also. I read about some software called 'CWSL_TEE', but it seems that, to use this, I would have to run a Windows PC as well as the Linux one that runs the WebSDR and buy some 'Skimmer' software that I have no real need for.

Maybe I need GNURADIO running on my Linux PC? I have no experience of that, but it looks like a lot of experimenters are having fun with it.

(2) Are you going to support the new RP, announced recently by STEMLab:
https://www.redpitaya.com/n86/new-stemlab-sdr

I am still very pleased with my homemade transceiver based on RP running your excellent Hermes emulation software and PowerSDR. Congratulations on your success and please keep up the good work!

Regards from UK,

Mark.

Hi Mark,

I don't have any idea on how to interface WebSDR with Red Pitaya. According to the information at this link, only RTL-SDR and sound cards are supported.

I've started to port some of my applications to the new board. Once I get some of them ready and tested, I'll try to put together a SD card image for the new board.

Best regards,

Pavel

Pavel,

Thanks for the reply.

I will look into GNURADIO. Seems there is software that allows RP to be used as a front-end into that. Perhaps there is then a GNURADIO block that will emulate an RTL, or soundcard, into WebSDR.

Great news on your doing code porting for the new STEMlab 122.88-16 board. I guess the FPGA code will be simpler without the 125/122.88 sample rate conversion. If I can get the 125-14 RP I have now working with WebSDR, it will give me a good excuse to buy one of the new ones for my HPSDR transceiver;-)

Which is the best www for me to watch for news of your code for the new RP board? Here?

Regards,

Mark.

The code for the new board is in the 122-16 branch of the GitHub repository. It's possible to check the progress of the porting of the code to the new board via the commits history:
