When this happened before, do you know what happened to fix it?

I've had problems like that several times, sometimes from stations hundreds 
of miles away. Sometimes it is parasitics in the transmitter, and sometimes 
it is arcing in the antenna system.

Although it could be anything, for my cases the real long distance stuff has 
always been parasitics in transmitters. Parasitics are frequency selective, 
perhaps a few hundred kilohertz wide.

The close-in stuff from local stations has usually been arcing in antenna 
systems. Arcing in antennas is generally very wide bandwidth.

About half the time a nice call to the correct person at the radio station 
will get things fixed. The rest of the time it takes FCC involvement, which 
can be difficult. In the interests of smaller government and lack of skilled 
field engineers, the FCC has become far understaffed. You have to figure out 
how to work around the field engineer shortage problem, if you are sure it 
is the station's problem and the station does not want to fix it.
