Hi Everyone,
I just completed doing the A-to-B upgrades on the RF board for K2 S/N 1599.
The rig is about 5 years old and has run very well heretofore. In addition
to the A-to-B upgrades, I also installed new RF and SSB firmware, added
replacement crystals, and added the keying waveshape mod,
Steve,
You present a mystery. There is nothing that I can think of or see in the
schematic that would cause the VFO to be stuck on only one band. The VFO
lock is not something that is remembered across bands.
Is there any chance that the K2 is going into transmit on 20 meters? If so,
the K2
