[Elecraft] K3 Attenuation on Receive of 20 meter band only problem.

[Fred Smith]

Phil

Don't feel bad I did the exact same thing this morning, had my receiving
antenna on when on 160m then went to 20m same thing.

It took me 15 min to find what I had done all the time right in front of me.

73,
Fred/N0AZZ

Rick,

I just now discovered the RX antenna on.  I mean, Just seconds before your
message came in.  But, thanks for the quick response and the correct answer.

There are so many features on the K3, sometimes finding the problem is more
time-consuming.

thanks,

busy as you would expect and I have made a number of DX contacts on 15 and
10 meters this weekend.

signals.  These DO NOT appear at all on my K3.

far as I can tell.  I can transmit into my antenna through the KAT500 and I
have the low SWR (about 1.2:1) and my LP100A reads the right amount of power
output (key down).

something that could go wrong to result in single band RECEIVE attenuation
