[Elecraft] Strange K2 Powerup issue

[Mike Stunes]

On K2 #5943, my usual startup noises were as follows: clicking of all
the relays resetting, followed immediately by some relays switching
again. Recently I took the cover off, disconnecting all of the wires,
and reconnected everything. Now my power-on is as follows: relays
resetting, short tone emitted from speaker, some relays switching,
stutter in audio, normal. Installed options are KAT2 and KBT2.
Everything looks right and I'm fairly certain the KAT2 control cable is
fully connected because the menu options do appear. Any ideas?
