[BC] AM Modulation Monitor Off Air Monitoring

[Jerry Mathis]

The problem you face is that the modulation monitor needs a high-level RF input. Depending on the monitor, anywhere from 1 to 10 volts of RF. You can't get that from a receive antenna, unless you're right at the tower. They sell devices called RF Amps to go between the receive antenna and your mod monitor. Find/buy one of those, and your problems are solved.

>I have a spare Belar AM modulation monitor. When we bought our station we did not have a modulation monitior so I bought one then found later found one at the station. It needed some fixing which I did but I now have two modulation monitors. I spoke with a guy one time who said he had an am modulation monitor setup for off air monitoring and was using an old radio as the receiver. Anybody know how to do this?
