[BC] Dual Ferret Antenna...

[Burt I. Weiner]

If the fading is caused by a beat between interfering stations then 
it might be possible to eliminate that cause of fading by simply 
eliminating reception of the undesired signals.  If the fading is due 
to propagation then you have a problem.

In the past I have solved some coverage issues by simply moving a 
stations carrier 10 or 15 Hz away from the interfering 
signal.  Sometimes it works, sometimes it doesn't.
