[Elecraft] [K3] Relay click - SOLVED.....

[Ray Albers]

….thanks to comments and suggestions from K9ZTV and W2CS.

My K3 has the Sub Receiver installed, and I have been playing around with
diversity reception, using a random wire connected to the sub-receiver
antenna input BNC connector.  Apparently the carrier operated relay that
protects the receiver from overload is being triggered by lots of RF coming
into that random wire. When I disconnect the receive antenna, no more
clicking. Now that I know what it is, I'll just ignore it. Or maybe someday
I'll rig a manual T-R switch arrangement to disconnect the sub receiver
antenna except when actually using it.

Thanks, gents!
