Hi,
I just bought a radio scanner (radioshack pro-83) and want to listen to
airband frequencies, however, I cannot find any on the airband. I tried
doing the scan, and even tuning to specific ones, like Boston ATC and
whatnot, but cannot hear anything.

Other frequencies, such as Police/Fire I hear just fine. I am
approximately 10 miles away from a major airport.

Am I doing something wrong, or I really have to be close to the airport
to hear them on the scanner?

Thanks.

Kind regards,
george
