■ LAND channel group

A max. of 100 programmable LAND mobile channels (allo-
cated 146.000 to 174.000 MHz) can be programmed into the
LAND channel group for simple communication with LMR
transceivers in the VHF band.
Proper FCC licensing must be observed, for both legal
purposes and to avoid frequency interface with other radio
users; contact your authorized Icom dealer for details.
Moreover, any of the marine channels in the USA, INT and
CAN channel groups can be programmed.
The default setting of the LAND channel group is the same
as that of the INT channel group. Ask your local Icom dealer
for the LAND channel group setting and LMR frequency pro-
gramming details.
