271. The nearest Coast Guard station is being called by a vessel on Ch-22. That vessel's USA-INT switch is set to INT. What will be the results?
Due to differing channel plans, the Coast Guard uses a simplex frequency (22A) while the vessel, set to international mode, uses a duplex frequency on channel 22. This allows the Coast Guard to receive the vessel's call but prevents the vessel from receiving the Coast Guard's response.
