[Elecraft] continuous relay click in RX ANT IN

[Jorge Diez - CX6VM]

Hello,

 

I have my beverage connected to the RX ANT IN and I can transmit into my TX
antenna while RX ANT is turned on without problem.

 

I tried to connect my 40 mts yagi to RX ANT IN because it was listening very
good, but I hear a continuous clicking, like a relay. What´s that? Why with
one antenna is OK and with the other I hear this click click click?

 

Any idea?

 

Thanks,

Jorge
