LiveATC.net is primarily a streaming audio network consisting of local receivers tuned to aircraft communications around the world. It is also a large community designed to unite pilots, student pilots, flight instructors, air traffic communication enthusiasts, FBO operators, and real-world (and virtual) air traffic controllers. Its target audience is anyone who can learn from or just enjoys listening to or discussing aviation communication topics. The community is supported by volunteers who live within radio range of airports and who use spare radio and computer equipment to relay airband transmissions into the LiveATC.net audio network.
