Default Getting local AM station engineering aware of harmonic problems

If station is being sold then maybe potential new owner would like to
hear that signal is AFU. Perhaps you contact them and they will have
present owner fix before papers signed.

If that doesn't work then here's what I would do. Get yourself some
spraypaint, gasoline and an old mattress. Spraypaint a small blurb
about a dirty signal on the side of the radio station. If is located
in an urban area this is even better. Throw the mattress down and soak
with gasoline and light her up. Call up a few local TV station and
tell em the studio is on fire. They will send a crew over and film the
mattress and the blurb you wrote on the side of the building and a good
chance it will be fixed right away.

I have a local MW station (630 WMAL) that is radiating harmonics (1260,
1.890, etc.) on up the spectrum.

The harmonics are strong enough that 1260 AM (also a local station) is
unlistenable for about a mile surrounding WMAL's towers. It's also an
irritation throughout the SW bands.

I am rather certain that the harmonics are coming out of the
transmitter and not the result of local rectification (near or in the
receiver) because building a trap for 630kHz has no effect on the
harmonic and the harmonic is present over a very wide area.

My first attempts (calling the station, writing a letter) have been met
with no acknowledgment that there is a problem (it is not even obvious
that anyone understands that there MIGHT be a technical issue to pass
on to engineering.)

Any advice?

Tim.

That company's in the process of being sold, isn't it? Citadel might
be more cooperative than Disney.
