Gary,
You should not have mic bias set on for that microphone element and
since that is a low output element, the mic gain range should be set to
high (FP.H. if you are connecting to the Front panel jack, otherwise RP.H).
To set up the mic gain, put the K3 into TX TEST and initially set the
mic compression to zero. Then adjust the mic gain to produce 5 to 7
bars on the ALC display. After than, set the compression as you desire
(listening with headphones to the monitor may help you determine the
correct setting).
You may try doing the Reference Oscillator calibration. Strange and
unrelated as it may seem, I have seen that clean up distorted SSB signals.

@ Jay,
Review the MIC CONFIG settings and maybe your TX equalizers
settings
Never used them but just looked at the Tx EQ and it is flat @ 0.
Mic select is front panel, MIC+LIN is off
@ Bill, Mic is an old Heil HM-5 desk mic & the element is an old Heil
HC-4. Nothing plugged into the audio jacks except my Bose QC15
headset is in the phone jack. The element only has two connections, I
haven't set bias anywhere. Maybe I should experiment with the bias
settings but I don't see that in the menu or config options.
