VHF Marine Channel Assignments

•

Three (3) sets of VHF channels have been established for marine use in the U.S.A.,

Canada, and the rest of the world (International). Most of the channels are the same

for all three (3) maps, but there are definite differences (see table on the following

pages). Your radio has all three (3) maps built into it and will operate correctly in

whichever area you choose.

The following is a brief outline of the channel assignments in the U.S.A.
