Bob,
Two things are possibilities.
1) There is a marginal solder connection on the Front Panel board that
has oxidized. Look at the soldering for RP1 and U2 as well as the rest
of the board.
2) The data in EEPROM has been corrupted. To correct will require a
Master Reset - BUT - that will wipe out all your menu settings including
the PLL data and your filter settings.
Before the Master Reset, download the K2 A to B instructions which
contain a nice section for recording your settings. You will need the
internal frequency counter probe.
After the Master Reset, do a CAL PLL and restore all the menu settings.
73,

It's been a few years since I last used my K2. In firing it up, I find that I
have
somehow locked the Preamp button into a stored msg mode. Everytime
I try to select the Preamp I get a msg being keyed. I've gone through
the manual, but can't find a way to cancel this and get my Preamp
function back.
