Abstract:

The areas of increased SITOR Simplex Teleprinting Over Ratio communications and the effects of Digital Selective Calling DSC on Coast Guard communications primarily in distress frequency guarding are studied. To determine how SITOR might be utilized for Coast Guard communications and how its use with merchant vessels could be expanded, the communications capabilities of Coast Guard cutters and a Communications Station are briefly described. The potential uses of SITOR on cutters are then discussed and the cost benefits that might be realized by increasing SITOR and DSC use between merchant vessels and Communications Stations rather HF CW are indicated. A test plan for SITOR communications and DSC operations in the Fourteenth Coast Guard District is provided for a late Fiscal Year 1986 test. Keywords High frequency, Distress communications, FGMDSS.
