Okay, I have gone through all the filters and adjusted them using a
noise source and spectrogram. The carrier showing up on PTT in USB or
LSB has disappeared but I think this went away with installing the top
cover.
I still have problems with the audio. I set the dial frequency to
14200.00 USB and transmit a 700Hz tone. Monitoring the transmitted
signal with my K3 and P3 this is what I see. The expected spike at
14200.70, another shorter spike at 14.201.40, and another small spike at
14.202.10 -- exact multiples (harmonics) of the original 700Hz tone.
These spikes show up on all bands but 20 is the only band I have
actually used the P3 markers to measure.
What should I be checking for that could cause this?
Thanks,
Mike - KI0HA

Mike,
I can't say for certain, but yes, your carrier balance may not be
optimized *and* your SSB OP1 filter settings may not be correct.
Either or both could cause the condition you state.
