What is the CG VHF-FM working frequency?

• A. 157.1 MHz
• B. 2182 kHz
• C. 121.5 MHz
• D. 156.8 MHz

Answer: (A)

In VHF-FM maritime communications, you establish contact on the distress and calling channel, then use a dedicated working frequency for normal routine conversations. The Coast Guard designates 157.1 MHz as its standard VHF-FM working frequency for these routine operations. Channel 16, at 156.800 MHz, is reserved for initial calls, distress, and urgent communications, not for ongoing routine traffic. The other options belong to different functions: 2182 kHz is a long-range MF/HF distress/calling frequency, 121.5 MHz is an international emergency beacon frequency, and 156.8 MHz is Channel 16. Therefore, 157.1 MHz is the correct working frequency.
