[Elecraft] Update: K3 Issues Since Synthesizer Upgrade

[Guy Olinger K2AV]

About #2, make sure you did not accidentally have the AGC off. If you like
to operate without AGC, you can set the AGC to not cut in until a signal is
quite loud, and then holds anything higher to the same level. It's kind of
like AGC OFF with a safety valve.
