Topband: K9AY Loop not performing

[Michael Walker]

Hi Pete

That is one interesting find.  I'm going to have to do some tests and see
if I have the same issue.

My RX antenna and TX antennas are about 2 wavelengths apart and both are
very well choked into a 2x8 switch.

I am going to have to give this some thought.
