Hello Jay!
Have you tried putting a string of "RF Suppression Snap-On Ferrites" on the
power cord?
Are the dimensions of the cord such that it is possible to use "RF Suppression
Snap-On Ferrites"? The largest I could find are .75" inside diameter.

If the power cord for the electric stove is too large, perhaps the Snap-On
Ferrites could be added to the Romex cable feeding the stove outlet if the
wiring is accessible, such as in an unfinished basement.

Subject: Topband: RF interference from 160m to GE Electric stove
Hi guys – I have recently added a 160m amp to my station and have created an
RFI problem I can’t solve.
When I transmit on 160 with any more than 150 watts, the GE electric stove in
the kitchen ALARMS and must be reset. I guess the 160 signal from the vertical
is getting into the AC power lines (just a few feet away from the AC feed off
the pole) and then into the electronics into the stove. Reducing the output
power to 125 watts or so does not cause the problem. Not a permanent condition;
hitting the stop button on the stove controls stops the stove alarm but starts
again when I transmit. My XYL HATES alarms—she is a retired ICU RN and I think
she got conditioned to panic when ANY alarm goes off !
Anyhow I wondered if anybody has any similar experience with problems like this
on 160 and how to solve them. I am tempted to just have an electrician come in
and install a BIG RF filter on the AC line – either just on the Stove line or
to the main feed but I fear this is a lot of $$$. I am hesitant to do this one
on my own for insurance reasons if nothing else.
Any ideas ?
Thanx – Jay NY2NY
