[NCC] rfi every 64 kc

[Jeffrey Ach]

RRR

Wall warts, or any switching supply could be the culprit.  It could be
lighting too....like dimmers.

Easiest thing is to use a battery op radio, and start shutting stuff off at
the breaker panel.

Pull your wall warts! Smash them! Every one of them!

Even your cell phone chargers...

You never see a cell phone or laptop charger during a DX contest at K3LR!

since I had today off, I've been trying to track down the interference
that's been wiping out 160m here. It's a loud buzz, like power line noise,
every 64 kc....it seems centered at 1.834 mhz, and it's close to 10kc
wide... I hear it at 1.899, 1.770, 1.703, etc....I hear it on both radios,
now heres the catch....I have 6 antennas, with a 2x6 box at the tower, and 2

feedlines coming in to the shack. With no antennas selected, I still hear
it....with no feedline connected, I dont....so it's like the feedline is
picking it up....so looking for suggestions on what to look for (with all
the electronics in the house, I'm thinking some sort of wall charger) and
also ways to keep the feedline from picking it up....
