Local AM staiton FMing and Harmonics in 80 meters.

Is there a place I can report this in the FCC? Local Station 1380 am
(5kw) has Harmonics at 3400 and 4000 and they are 40 over S9. Lots of
little birdies in between make 80 pretty useless. Its only in the last
month or two.
Well, the harmonics of 1380 are 1380, 2760, 4140, 5520, 6900, ...
None of those match your problem frequencies.
As a result, one suspects there is some mixing going on there, either at
their end or at yours.
The antenna is about 10 miles from me.
They are planning and have approval for 50KW now and Im worried that
160 and 80 and possibly 40 could me usless.
KRKO is listed on the FCC pages as on 1380, but about 2.4 miles from you,
and with an application for 50 kW day and 34 kW night, but that is listed
as being 8.5 miles from you, so they may be moving.
I would suggest you try listening for the signals somewhere else in the
area, to determine if they are from something local to you (such as a
mixing result of a rusty rain gutter downspout, or the front end of your
rig), or if they are actually transmitting those signals.
If it really is found in places far from your location, then nicely
contacting the stations engineer for help is likely to get good results.
It is great to have these guys for friends -- they have some neat toys.
