Short Description AUTOSPEC is a synchronous FECForward Error Correction teletype system used by British coastal stations to communicate with North Sea oil rigs. Also known as Autospec-bauer, Bauer, and Autospec Mk1. This signal is most likely phased out.
I/Q Raw Recording
Audio Sample
AUTOSPEC was a synchronous FECForward Error Correction teletype system used by British coastal stations to communicate with North Sea oil rigs. Also known as Autospec-bauer, Bauer, and Autospec Mk1. This signal is most likely phased out. This signal typically used 62.3, 68.5, or 102.7 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second., along with 137 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.. It uses the ITA-2 alphabet encoding with Bauer Forward Error Correction (FECForward Error Correction). Uses a 270 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). FSKFrequency-Shift Keying shift.

AUTOSPEC may also have been used by the South African Navy, Brazilian Navy, and Romania's Diplomatic Stations.
