I'm seeing the modulated output of %XRFTEST offset by approx. 1.675 MHz from the set frequency. Modem version is v1.2.2
Here's my command:
AT%XRFTEST=1,1,1,19500,23,1,1,6,0,0,3,3,0
And here's the spectrum:
I see this in multiple bands.
Am I missing something? The documentation seem to indicate that only CW tones will be offset, and by much less than 1.675 MHz.
