K3 RX antenna input

[Gerard Jendraszkiewicz]

Hello All,

Anyone know if the RX antenna input is shorted to ground when the K3 is
put into TX mode ? I have been getting some funny stuff going on when I
use my amp on 80m and beverage antenna.

Thanks
Jerry, KE9I

Jerry,

If the "funny stuff" is hearing a clicking sound, that is the sound of
the COR relay kicking in to protect the receiver.
The only cure is better isolation for your receive antenna from the
transmit antenna.
