Topband: Chokes, et. al.

[Mike Waters]

I'm in full agreement with this, unless we consider our shack computer part
of our "gear". :-)

I could not avoid a severe RFI problem on 75/80 meters without winding my
CAT5 network cable around some large #31 ferrite cores. Without that choke,
I can hear my TX signal in my computer speakers, which I also have
connected to my rig through the sound card (for several very good reasons).
I have CAT5 running all over the house, and one run of it is apparently
resonant. (And yes, I tried ferrite in various other places on every piece
of it that I could get to, and nothing else worked.)

I also have a split core around my keyboard cable, to keep it from
radiating RFI.

73, Mike
