Subject: Re: [TenTec] Problem on 160 meters, Whats up?
Thanks, Bob. Actually, I should have pointed out in my original post the loop
was designed for max performance on 80 meters and above. I have a separate 160
meter antenna system. I was just agreeing that the BT1500 does not perform
well on small antennas on 160.
Also, please advise what date Kirk Kleinschmidt's article appeared in QST. I'd
like to review it.

Scott K4VWK
