receiving antenna signal level tolerance
James Del Principe

I have just completed a K9AY loop for receive only on the low bands. While transmitting, I noticed the signal level displayed on the panadapter is bright white to red, indicating a very high signal level into the receive antenna. Of course, this would not happen using only an antenna on input 1 or input 2 which are switched during transmit. My concern is causing damage to my 6500 during transmit. I know there are ESD diodes for surge protection but I don't see that as a solution in this case. Short of creating a switch on the receive antenna coax to short the line during transmit, how do you handle this? Is anyone else using a receive antenna and how do you deal with this? Many Thanks, Jim KD1I

Gayle, I think you are right. I will need to construct a switch box with relay to do just that. Grounding the antenna and perhaps the Receive input should do the trick. Thanks for the reply. Jim0

Bill, I will look for that chart. I have the receiving loop away from the house but very near my OCFD..... not so good. Long term, I wanted to put a vertical up for 160/80 meters in the front yard, away from the house and other antennas. Thank you for the suggestion. Jim0
