Can I listen to control tower frequencies on a ham radio legally Is there a frequency I can tune into to listen to airport I’m in Durham by RDU AIRPORT and would like to listen in on a ham radio only legally
In North America, just buy an air-band radio and listen to Raleigh-Durham tower all you like, or if your ham unit receives the aviation VHF frequencies, do that.  Or find it on LiveATC.net  It's only illegal to broadcast without authorization, not listen in.
