Jerry,

Not sure I understand; are you saying that your KX3 transmit frequency is
actually DIFFERENT than its receive frequency (with RIT and XIT off)? I
didn't think that was even possible. I understand that your KX3 may not
display the correct frequency when tuned in correctly to an ssb signal,
but that's just a matter of running the frequency calibration on the KX3.

As for crawling up and down the band as a result, if you tune in the SSB
signal so that it sounds proper, the other station should be receiving you
at the proper 'pitch' as well. No need for anybody to change the VFO dial
if you're tuned in. Yes, your frequency display may not agree with the
other stations frequency display, but tuned-in is tuned-in (unless the KX3
TX and RX can truly be on different frequencies).

Hope I didn't muddy the waters any further with this; just trying to
understand what's happening.
