What is the official frequency manual?

• A. Spectrum Management COMDTINST 2400.1H
• B. Radiotelephone Handbook COMDTINST M2300
• C. The Maritime Communications Guide 2000
• D. Electronic Communications Regulation 1200

Answer: (A)

Understanding who controls how radio spectrum is used is key here. Spectrum Management COMDTINST 2400.1H is the official policy document that governs how the Coast Guard plans, assigns, and coordinates radio frequencies, coordinates with the FCC and other authorities, handles interference, and ensures compliance with national and international rules. It provides the formal procedures for requesting and approving frequency usage, keeping allocations organized across all units, and maintaining proper engineering oversight. The other documents describe operating procedures or general guides rather than the formal rules for spectrum management: the Radiotelephone Handbook covers day-to-day radiotelephone operations, the Maritime Communications Guide is a broader reference for maritime communications, and Electronic Communications Regulation 1200 isn’t a Coast Guard frequency-management instruction.
