What is the frequency value for Channel 13, the bridge-to-bridge channel?

• A. 156.65 MHz
• B. 156.80 MHz
• C. 2182 kHz
• D. 156.70 MHz

Answer: (A)

Channel 13 is the bridge-to-bridge channel, and its fixed frequency is 156.65 MHz. On marine VHF radios, each channel number corresponds to a specific frequency, so selecting Channel 13 tunes the radio to 156.65 MHz for inter-ship coordination, especially when communicating with vessels passing under bridges or coordinating in busy waterways. The other options aren’t Channel 13’s frequency: 156.80 MHz is Channel 16, the primary hailing and distress channel; 2182 kHz sits in the MF band and is used for long-range maritime voice distress and calling; 156.70 MHz is a different VHF channel with its own designated use.
