Fig 3-45 Frequency Preset – Select Maritime Channel
Channels are only available when using the Maritime waveform. Each channel stores separate
predefined transmit and receive maritime VHF frequencies. Channels cannot be altered by the
user. The radio can be set to either ‘Ship’ or ‘Shore’, which swaps the stored transmit and receive
frequencies. Also the ‘International’ or ‘American’ frequency sets can be selected. The factory
default is ‘Ship’, ‘International’, Channel 16.
