ABOUT VHF MARINE RADIO

The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with some shore stations available between 161 and 163 MHz. The marine VHF band provides communications over distances that are essentially “line of sight” (VHF signals do not travel well through objects such as buildings, hills or trees). Actual transmission range de- pends much more on antenna type, gain and height than on the power output of the transmitter. The approximate distance a portable 5W radio may communicate is about 5 miles in if there are no obstructions (build- ings, hills etc.) restricting line of sight transmission.

ABOUT LMR CHANNELS

The HX370S is capable of PC programming 40 LMR (Land Mobile Ra- dio) channels by a dealer. The frequency range is 137 to 174MHz which may be setup for 25kHz (wide) or 12.5kHz (narrow) channel stepping with CTCSS and DCS signaling. Contact your dealer or Standard Horizon Product Support (800-767-2450) for further details.
