Which frequency is designated as CG to Civilian communication?

The frequency designated for Coast Guard to civilian communication is 22A. This frequency operates at 157.100 MHz and is primarily used for non-emergency voice communication. It allows the Coast Guard to communicate effectively with civilian vessels, particularly for safety announcements, navigational information, and other operational matters.

While other frequencies mentioned, such as 16 and 13, are crucial for maritime communication (with 16 being the international distress frequency and 13 used for bridge-to-bridge communication), they are not specifically designated for CG to civilian communication. Channel 22A serves a specific purpose in enhancing coordination and safety at sea, making it the appropriate choice for this function.
