[Elecraft] dons switch box

[Don Wilhelm]

Ron,

What has changed just prior to yesterday?  Did you change antennas?  Has 
your coax failed (any coax in the system)?  This sounds like a case of 
RF feedback, but it could also be that there is a marginal solder 
connection that is acting like a diode and rectifying (detecting) the RF 
signal.
