In this document, the Commission amends its rules to promote operational, technical, and regulatory flexibility for Automated Maritime Telecommunications System (AMTS) and high seas public coast stations. These final rules will eliminate the application and engineering study requirements and modify the broadcaster notification requirement for new AMTS stations that qualify as fill-in stations, extend the construction requirement for new AMTS systems from eight months to two years, provide AMTS licensees with much-needed technical flexibility, extend the high seas public coast construction requirement to twelve months, and eliminate the HF channel loading requirement for high seas public coast stations. The Commission believes that this action will increase competition in the provision of telecommunications services, promote more efficient use of maritime spectrum, increase the types of telecommunications services available to vessel operators, allow maritime commercial mobile radio service (CMRS) providers to respond more quickly to market demand, and reduce regulatory burdens on AMTS and high seas public coast station licensees.
