Interesting point...

Not that I have the answer to your question, because I don't. Commercial FM broadcast stations won't have 'bleedover' problems, as I'm pretty certain that they must have enough filtering to assure they are where they are supposed to be due to FCC regs - bandwidth-wise. Pretty sure that FM receivers in our cars/home aren't made to be as sensitive as our kind of radio gear is.

Since our CB/Ham radios are built to be very sensitive - mere microvolts give us S-unit readings. Not to mention that many Ham radios have preamps to amplify these very weak electrical signals even further.

Having said that, with as much energy coming from a 5,000 watt station that close to a radio that is built to be very sensitive with minute power changes, fundamental overload might be able to damage a receiver.

I've also heard stories - 'anecdotal evidence' - of receivers being blown out by stations that don't even run that much power. The use of Shottky diodes can also lend to such a situation. Indeed, there are mods available for the Ranger TR-696 found on the Defpom page that will give the receiver a great boost that I've read about. But a warning came with it, saying that damage may occur if a strong signal may be present.

Just some thoughts.
Looking forward for some replies and info from this thread...
