Radio GTMO, officially titled AFN Guantanamo Bay, is the United States military radio station at Guantanamo Bay Naval Base (GTMO), in Cuba. Operated locally by Mass Communication and Interior Communications Electrician sailors of the U.S. Navy assigned to the American Forces Network Europe, the station serves approximately 6,000 American service personnel and their families stationed at the military base. Three different radio programs are broadcast simultaneously, carried on one AM frequency and two FM, but the transmitters are only strong enough to cover the base, and are not heard in the rest of Cuba. The station is known for its collection of 22,000 vinyl records and reel-to-reel tapes, kept in place despite orders to the contrary.
