3.ABOUT THIS RADIO
3.1ABOUT 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 distances can be greater than 15 miles, for a portable 6 W radio transmission 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 rescue case, or contribute to a collision between passing ships. For VHF Marine channel assignments refer to page 42 section 10.
