Tom, yes I would put up some receive antenna's but open up the TX antenna during receive with a simple relay at the base of the transmit antenna. This will remove the coupling.

I had the usual local QRN on the 160 tee vertical and even the low doublet last night. Very frustrating, especially in light of not having room for listening antennas. In any event I listened for 3B9C from my local sunset until his local sunrise and only heard an occasional Q3 peep from him at times. He did peek here one minute after his local sunrise on my low doublet but only to a brief Q4.

Then at about 0230 UTC I noticed that I had 12 db of attenuation in line on the receiver so this helps explain why 3B9C was so weak here, gggrrr!!! It was an I/O error. For those of you who have worked in the mainframe computer programming field since the 1960's, you will recognize an I/O error as an in/out error. But in my case it's an IDIOT OPERATOR error!

BTW I live on 1/4 acreville in suburbia and there is no way to put out any receiving antennas, at least far enough away from the transmit antennas to prevent QRN coupling. I rarely post questions on the reflector but does anyone think that it's worth the effort to put some flag receiving antennas up here when they would be so close to the transmit antennas?
