[RFI] Trying to locate the Part 15 compliance note...

[Hare, Ed W1RFI]

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.
