The clicking relay turned out to be in an amplifier keying circuit a
previous owner had installed.
Problem solved!

Thanks, Don. It’s a K2/10, so I’ll do the relay touch-test.

Dave,
I am at a loss to tell you what is going on. The T/R switching in the K2 is
all electronic, no relays involved.
If a K2/100, break it down to just the base K2 and see if it is in the base K2
or in the KPA100.
If you have the K2/10, remove the top cover which contains the KAT2.
If it occurs in just the base K2, hold your finger on the relays one by one and
see if you can detect which one is switching as you key the K2.

Recently bought a K2 and all was working well (silent QSK) until I moved from
one spot on the bench to another. It was powered up and one of the leads fell
off the power supply connector, so this was a live power interruption. After
this, there are relay clicks when sending CW. I did a reset, but this did not
change the relay clicks. Built the probe and did the CAL FIL routine and got
it back on the air successfully.
S/N 100, with ATU and SSB board.
It would be nice to get back to silent QSK and preserve relay life. Any
suggestions appreciated!
