THE NEW GREAT LAKES LAKES-WIDE ALL-VHF AUTOMATED MARINE TELEPHONE SYSTEM

This paper presents a brief description of the Great Lakes Lakes-Wide All-VHF Automated Marine Telephone System (the System) and proceeds to describe four of the System's unique problems and the answers developed. The problems considered herein are concerned with the especially serious effects on automated services of co-channel interference due to ducting phenomena; with direct dialing from ships, particularly as to use of the proper shore station and selection of the appropriate working channel; with automated handling of ship reports to their Dispatchers and the National Weather Service; and with direct-dialing guidance to land callers to obviate the need for foreknowledge as to ship location.
