I agree with Jim; this problem is being caused by the fundamental signal of
your station. Harmonics from that amplifier are down many tens of dB and if
500 W causes your problem but 100 watts does not, those harmonics that are on
the order of milliwatts even if the amp is in horrible condition would not
overload the stove.

Dave,
There is absolutely NO technical reason for doing this. By definition, any
product that is not intended to act as a radio receiver should be susceptible
to radio transmissions. If it is, it is defective in design and/or
construction. The only way we could possibly be at fault in an RFI case is if
we transmit harmonics, intermod, or spurs ON THE FREQUENCY that a radio
receiver is tuned to. Anything else is the fault of the victim product.
