Hi all,
Why is it that 243.000MHz and other mil air freqs sometimes have what sounds like an "open microphone" - no voice, just the sound of an "empty" transmission? Is this what is called a "carrier"? If so, what is the purrpose of it? Or is it just that the mil air band is easily affected by electrical noises from computers, flourecent lights, microwave ovens, etc?
It is frustrating to have the scanner lock up on to these. Should I be patient and keep listening? Will somebody eventually say something over the air?
Sorry for all the questions - I'm fairly new to mil air.
