DescriptionRadio towers LOC hec.13475.jpg |
English: en:NAA (Arlington, Virginia). NAA was a major radio facility located at 701 Courthouse Road in Arlington, Virginia. It was operated by the U.S. Navy from 1913 until 1941. The station was originally constructed as the Navy's first high-powered transmitter for communicating with its bases across the U.S. and the Caribbean. During its years of operation NAA was best known for broadcasting daily time signals, however, it also provided a variety of additional services, using multiple transmitters operating on frequencies ranging from longwave to shortwave. The station also conducted extensive experimental work, including, in 1915, the Navy's first transatlantic transmission of speech.
