My K2 works great both on RX and TX in CW. Also RX on SSB is splendid, but
my SSB TX sounds like a built in unfiltered switchmode supply. During
alignment I can listen to my voice in the headphones and it sounds ok. But
during "normal" mode in SSB TX has a whining sound. It increases at the
upper part of the band and decreases I frequency at the lower portions of
the band. I have tried running my K2 from a car battery - but the sounds are
still there. I have checked all components for misplacements and values and
are correct. Weher do I look?
