Your debugging sounds already pretty good. Some more stuff you could try
- assert that there are no overruns (āOās or āDā on the console)
- check that frame detection is working (there are no frames detected when the
transmitter is turned off)
- test with antennas
- assert that you connected the correct antenna ports (RX and TX use a
different ports by default)
- set a different LO offset
- use the LMS equaliser
- try a different sample rate / bandwidth
- check if the signal field is decoded correctly (log or debug option)
Best,
Bastian
