Morse code [SEP] Other uses
Radio navigation aids such as VORs and NDBs for aeronautical use broadcast identifying information in the form of Morse Code, though many VOR stations now also provide voice identification. Warships, including those of the U.S. Navy, have long used signal lamps to exchange messages in Morse code. Modern use continues, in part, as a way to communicate while maintaining radio silence. ATIS (Automatic Transmitter Identification System) uses Morse code to identify uplink sources of analog satellite transmissions. Many amateur radio repeaters identify with Morse, even though they are used for voice communications.
