3. ABOUT THIS RADIO
3.1 ABOUT THE VHF MARINE BAND
The radio frequencies used in the VHF marine band lie between 156 and 162
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 5 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 waterway, or
propagation anomalies may cause your transmission to be heard in a water-
way. 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 32 section 9.
3.2 ABOUT THE LMR CHANNELS
The HX380 is capable of being programmed with 40 LMR (Land Mobile Ra-
dio) channels by a dealer. The frequency range is 134 to 174MHz which may
be setup for 25 kHz (wide) or 12.5 kHz (narrow) channel stepping with CTCSS
and DCS signaling. Contact your dealer for further details.
3.3 ABOUT WATER RESISTANCE
Water resistance of the transceiver is ensured only when the battery pack is
attached to the transceiver and MIC/SP cap is installed in the MIC/SP jack.
3.4 EMERGENCY
(
CHANNEL 16 USE
)
Channel 16 is known as the Hail and Distress Channel. An emergency may be
defined as a threat to life or property. In such instances, be sure the transceiv -
er is on and set to “Channel 16”. Then use the following procedure:
1. Press the
PTT
(Push-To-Talk: ) switch and say “ Mayday , Mayday , May-
day . This is _____, _____, _____” (your vessel’s name).
2. Then repeat once: “ Mayday , _____” (your vessel’s name).
3. Now report your position in latitude/longitude, or by giving a true or magnet-
ic bearing (state which) to a well-known landmark such as a navigation aid
or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, fire, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance your desire (pumps, medical aid, etc.).
6. Report the number of persons aboard and condition of any injured.
