3. ABOUT THIS RADIO
3.1 ABOUT THE VHF MARINE BAND
WARNING
The radio frequencies used in the VHF marine band lie between 156 and
158 MHz with NOAA Weather stations available between 161 and 163
MHz. The marine VHF band provides communications over distances
that are essentially “Line of sight” Actual transmission range depends
much more on antenna type, gain and height than on the power output of
the transmitter. On a fixed mount 25 W radio transmission expected dis-
tances can be greater than 15 miles, for a portable 6 W radio transmis-
sion the expected distance can be greater than 5 miles in “Line of sight”.
The user of a Marine VHF radio is subject to severe fines if the radio is
used on land. The reasoning for this is you may be near an inland water-
way, or propagation anomalies may cause your transmission to be heard
in a waterway. If this occurs, depending upon the marine VHF channel
on which you are transmitting, you could interfere with a search and res-
cue case, or contribute to a collision between passing ships. For VHF
Marine channel assignments refer to page 38 section 10.
