Glenn,
That condition would occur if the USB BFOs are set on the wrong side of the
carrier.
There is a sideband reversal that occurs on 15 meters and above, and the
symptom will 'switch sidebands' for the upper bands.
I suggest you re-check the BFO settings, start with the settings shown in
the KSB2 manual for the crystals you have in the KSB2 and then refine those
settings using Spectrogram. While setting the filters, be certain the K2 is
set to a lower band to avoid confusion, the K2 firmware handles the sideband
inversion and that will appear to 'flip' things for you.
If you need additional information about setting the filters and BFOs, check
my website www.qsl.net/w3fpr - look at Step 3 of the article dealing with K2
Dial Calibration.

I thought that my recently finished K2 had come through test and it's
forst operational period with flying colours...I was wrong.
... snip ...
I then got him to listen in USB and I called him on LSB...and he answered
me and he was good copy !
I'm still scratching my head over this whilst looking at the manual. It
appears that I'm intermittently switching to LSB, and when there, I cannot
resolve signals. The radio is also txing in USB when it says it's in LSB.
