Gary,
If the same problem happens again, try removing the Control Board MCU U6
from its socket, and then putting the IC back into its socket. I had the
same problem twice, once a couple of years after building the K2 and again
about a year later, although the power level control did not work either.
The cause of my K2's problem in both instances was poor contact between one
or more of U6's pins and the socket due to 'corrosion', a known design
problem with the type of socket supplied. In the end I replaced the socket
with turn pin (machined) type.

I took out the control board and checked the solder connections. I re
flowed some of them that looked suspect. My K2 is now up and running
again.
Thanks,

My K2 #6113 just quit working. I was listening to the 40 meter band and
all of a sudden no signal, and no audio. The display works but, the
frequency is frozen. The only other control that works is the power
level. None of the buttons work and the frequency can't be changed.
There are no error messages on power up and it powers up as normal with
"Elecraft" and then goes to the frequency.
I'm getting ready to take out the control board and have a look. Any
help would be appreciated.
I recently had a problem with SSB transmitting just stopping so, I may be
related.
Thanks,
