[RFI] Tower Intermod - Control Lines

[K8TB]

Ed,
     How far away are you from the AM broadcast stations? If this was 
the US, there is a Google Earth app that shows this. Keep in mind that a 
possibility is that something on your system is picking up the AM 
stations, and creating the mix. This could be rotor lines, remote 
antenna relays, and the proverbial metail rain downspout. Don't laugh, I 
DF'd one some 35 years ago. Just slightly tapping the sections would 
make the, in this case, 3rd harmonic, come and go.
