Carlos:
The frequency determining values and math are written in firmware.
There are no adjustments.
The only adjustment related to frequency is for the master oscillator
being U8 {GTXO_566}. I suggest you perform a Master Reset and then
remeasure your radio. CW mode and AM mode should be the same
frequency. As to SSB mode, LSB and USB, I presume you have means to
actually measure the suppressed carrier frequency and not just "tuning"
the radio to what sounds correct.

Hi,
I noticed that the AM carrier (in 10 meters at least) is almost 600 Hz
lower than the supressed carrier in USB. So in USB the radio is almost
spot on, but in AM the carrier appears shifted to the left.
I checked with some testing gear (less than one year old, still
calibrated) and one SDR receiver. I'm not dreaming it.
I have the user manual and the schematics, but I cannot find any
procedure to adjust the position of the AM carrier.
Any help is greatly appreciated.
