Description

" A SITOR-B (SImplex Teletype Over Radio type B) idling pattern, part of the NAVTEX (Navigational Telex) system which issues navigational and meteorological warnings and forecasts, as well as urgent marine safety information to ships. This recording shows the characteristic synchronization bursts which are transmitted every second or so and last for slightly more than one second. Every few bursts, a Morse identifier of three letters - in this case, NMC, identifying this as coming from the United States Coast Guard station at Point Reyes.
