VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.” The FCC also determines who can operate in each band and who has priority if more than one user is operating.

Use an “open channel” to performance the check (channels 68, 69, 71, 72 and 78A). Turn radio to one-watt power setting, and key the microphone. Call “radio check” three times, followed by your boat name and location. Wait for a reply confirming someone has heard your transmission.
