[Elecraft] K2 is sick?

[Mike Baird]

My trusty K2 (#5767) has just started acting up.  It seems to be fine on all
bands but 40M.  On that band,  the RX seems dead, and won't tune properly
with my KAT500.  It doesn't have the built in tuner.  The 100W amp is built
in.  Other bands show full output and normal RX.  Using my other radios have
ruled out any antenna problem.

 

Anyway, any advice would be appreciated.
