Interval SignalAn interval signal is a characteristic sound or musical phrase used in international broadcasting and by some domestic broadcasters. It serves several purposes: - It assists a listener to tune his or her radio to the correct frequency for the station.
- It informs other stations that the frequency is in use.
- It serves as a station identifier even if the language used in the subsequent broadcast is not one the listener understands.
The practice began in Europe in the 1920s and 1930s and was carried over into shortwave broadcasts. The use of interval signals has declined with the advent of digital tuning systems, but has not vanished.
