@F4EXB - Edouard,
Thanks for the recent update and, yes, the SDRAngel application is working REAL well in SSB voice on HF with the delay, but if you can get that reduced to 1/2 second or less (PiHPSDR has a delay in and around 1/2 second to 3/4 second) then that would be great…! I’m not sure if SDRAngel has any affect on the other spectra that is produced when transmit happens, but I do notice that when the application is not transmitting that you can move the frequencies around and there’s no other interference or spurious, but when transmit is activated spurious will appear along with the 30 MHz and tuned frequency signals. Again, I’m not sure this is your issue - it may be a LimeSDR induced issue - but that can be tackled later, and for that matter I’ll take before and after pictures of the issue to you can also see what I’m seeing with this spurious signal issue.
I’ll try your new version this evening and see the results. SDRAngel is by far leading the pack when it comes to transceiver operations on HF with the LimeSDR. I’m real happy with the progress thus far and see A LOT of light at the end of a very long tunnel with the LimeSDR being a building block of a HF/VHF/UHF transceiver solution for Amateur Radio.
More to follow as I have it with the new version, Edouard,
