K2 Distorted TX audio on 10m and 12m only

[Jeff Laughlin]

My K2 sounds fine on all bands on all modes, both TX and RX except for 10
and 12m. On those two bands, RX is fine, but TX sounds horrible on all
modes, LSB, USB, and CW. It puts out full power though. Any ideas?

I'd really like to use this at field day. Of course 12 and 10 probably won't
even be open...

Thanks,
Jeff

I have a lot of distorted audio problems due to RF getting into my MH2
microphone or the mic cable.  It is worse on 12M, 10M, and 6M.  The higher
the frequency the worse RF pickup problems generally are.  If the rig sounds
normal when connected to a dummy load (or with power turned down to zero)
then it is certainly an RF pickup problem.
