VHF Channel 22A is used for Coast Guard to Public communications. What is its frequency?

• A. 157.1 MHz
• B. 156.8 MHz
• C. 157.05 MHz
• D. 157.15 MHz

Answer: (A)

Knowing how marine VHF channels map to frequencies helps you quickly contact the right station. Channel 22A is the Coast Guard to public communications channel, and its assigned frequency is 157.1 MHz. This pairing is part of the standard ITU marine channel plan, designed to keep Coast Guard/public contacts separate from other traffic. For contrast, the distress/calling channel is 156.8 MHz, which is a different channel used for emergency hails, so it isn’t the same as Channel 22A. The other frequencies listed correspond to other channels and do not represent the Coast Guard to public channel. So, 157.1 MHz is the correct frequency.
