Dave,
The two relays are K16 and K17. Download the manual from the Elecraft
website and you can view the schematics without having the paper copy handy.
Check the soldering carefully - a bad connection can produce the
symptoms you describe. Relay failures do occur, but they are rare
unless physically damaged. Except for ones that were burned by a
soldering iron, I have found only 2 relay failures in all the K2s that I
have serviced over the years.
