Mark, Harmonics are integral multiples of your frequency so whatever was
happening it wasn't a harmonic of your signal.
How close was the reporting station to your QTH? Strange things happen
when someone experiences fundamental overload of their receiver. If
able, arrange to have a look at your emissions on a good spectrum
analyzer. It might not be something you are emitting but something
created in his receiver.
One time in the early 60's I was reported to the FCC as causing TVI. I
had a 2nd class licensee prepare a fact finding report in response to
"The Letter" from the FCC. I was putting out a very clean 3 Watts on
the CB band and the "ancient" TV I was interfering with had an IF with
band width covering the CB freqs. I was transmitting directly into one
of the TV receiver's IF circuits. Solution: Hey dude, get a more modern
TV. End of story.

I was attempting to break through the pileup for 5H1WW on 80 CW the other
night. A ham emailed me the next morning and said he could hear a harmonic
of my CW signal 1.2 kHz down from my main.which unfortunately was right on
top of the DX station.
This is the first time someone has told me about this, but I think I read
somewhere about it happening to another ham on 160 meters.
Does this sound familiar to anyone? How did you resolve it? I was running
an amp at the time into an inverted L.
