[TenTec] Preselector for SDR

[Jim Brown]

It would work quite well as a receive antenna.  And yes, magnetic loops 
are well known to have quite narrow bandwidth, which would allow nulling 
interference along one axis.  N6RK uses a magnetic RX loop to null his 
own transmit antenna so that he can run SO2R during 160M contests. He 
puts one station on 1801 running (calling CQ) and the other station up 
the band in S&P mode (responding to stations calling CQ).
