My T41 seems to be mostly working, but I have not been able to do the Transmit IQ Calibration.? I am injecting 750Hz into the mic input, but I don't see any sidebands.? It appears that I am not modulating.? Is there a way to check the audio hat.? I have two of them, and they both work the same.? I do see the 750Hz coming on the Main board.?
?
I am using a KiwiSDR as my receiver for the cal procedure.? Any suggestions on how to proceed with troubleshooting?
?
I can do the freq cal, receiver cal, cw power amp cal.
?
