If the AM signal is 3x wider than a normal AM, you can be assured that it's coming out of the transmitter and being tripled both in carrier and sidebands.

If it is a "mix" from another transmitter or internal to the receiver, it will be normal bandwidth.... not three times as wide as a typical AM transmitter.

Quoting Roy Morgan <k1lky68@gmail.com>:

John and others,

Yes, I now see reports from far from the station.
Clearly my comments about causes local to the one nearby ham reporting interference do not apply

I will listen myself tonight.

Maybe some of our two trillion dollar aid package can be sent to Canada.
Perhaps a mere $100,000 would let them replace their troublesome guy wires with commercial grade Phillystran.

Notce Roy that a second report from W8 land also was hearing this 3rd harmonic... its the radio station problem... not the ham's problem...

And yes I also heard it from Northern Indiana

Is it possible that the interference is being generated not by the transmitter but rather by bad connections in power lines or utility pole guy wires nearer to
you?
