Topband: RF interference from 160m to GE Electric stove

[Arthur Delibert]

The product that does this is the MFJ Artificial Ground.  Costs about $160.


Good luck.

Another thing that might help if the
ferrites don't do the job is to run a wire
from a series variable capacitor and
variable/tapped inductor, to the stove or
possibly to the metal conduit the wires to
the stove are going through. This, with an
attachment to a counterpoise or ground.

My father had problems when he would
transmit on 80 and it would trigger the
system that used house wiring to turn on
various lights in the house when a phone
call came in on her line, or the door bell
was rung. She was totally deaf and needed
this to get to her TTY setup for a voice
operator to come in and translate speech
to her printout.

He did as I described and had a RF ammeter
in line. When the capacitor/inductor was
adjusted under a key down situation, you
could follow the result on the ammeter and
at the right setting, the interference
stopped triggering the in-line receivers.
Sometimes he needed to tweak the setting
but it always worked for him.

I think MFJ used to have something to do
just this, I don't recall what they called
it.

Good luck & 73,
