If you were successful in obtaining a good carrier null with a second
transceiver, then you can ignore it.
The way I adjust the SSB carrier balance is to observe the K2 RF output
with an oscilloscope connected across a dummy load. I do not plug in a
microphone, but plug in paddles and close the DOT paddle since that is
the same as PTT.
Set the oscilloscope vertical sensitivity to show the RF envelope and
adjust for minimum deflection.
Quick and easy and will produce good results. The second transceiver
will also produce good results, adjust for minimum signal on the S-meter.
