[Elecraft] Loud relay click on CW using RX ant only on some bands

[Don Wilhelm]

Chris,

You are hearing the COR (carrier operated Relay) engaging.
You have too much Transmit RF reaching your RX antenna.

The cure is to move your RX antenna further away from your TX antenna, 
or use one of the several solutions that disconnect (or ground) the RX 
antenna during transmit.
