On the 'tune-in' radio app for the Roku box and iPod, you can tune in to frequencies for major (SFO, DCA, MIA, JFK, etc.) I am always amused about how pilots get spooled up over trivial stuff like this. 123.025 MHz is the frequency for helicopters air to air communications. You don't have to listen to all that stuff. Radar could be used to track planes in the air and determine distance, direction, speed and even type of aircraft. [20] Such activity has been the subject of international situations between governments when tourists bring airband equipment into countries which ban the possession and use of such equipment.[21][22]. In 1912 the Royal Flying Corps had begun experimenting with "wireless telegraphy" in aircraft. Increasing air traffic congestion has led to further subdivision into narrow-band 8.33kHz channels in the ICAO European region; since 2007, all aircraft flying above FL195 are required to have communication equipment for this channel spacing. This will keep you out of trouble and show that you are well-versed in the correct aviation frequencies usage. Once you start using them over the United States or its coastal waters, however, you could have a very big problem potentially a $10,000 problem, to be precise. Historically, when aviation radio was first starting out, most air navigation transmissions took place on the low frequency band from 200 KHz to 415 KHz.
