What kind of radio do I need to listen to air traffic control?
Coffee is right on his frequency band. They are basically FM radio signals that are just barely over the limit of the receivers in most FM radios. 118.00 to 135.975 are the frequencies you would want to listen to. There is no law whatsoever about listening in, so don’t worry about that. However, if you attempt to transmit and interfere with any communications you could be in REAL trouble. Like multiple years of jail time type of real trouble. Keep in mind that because your receiver will be limited to a small range right over your head, you might not be hearing all the transmissions that are taking place. There are also websites you can use to simply listen in on a certain tower.
