This equipment has been tested and found to co mply with the limits for a Clas s B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio

INTRODUCTION

1.1 1.1

INTRODUCTIONINTRODUCTION
The STANDARD HORIZON GX1255S is a VHF/FM transceiver designed for use in the
frequency range of 156.025 to 163.275 MHz. The GX1255S requires 13.8V for operation
and has a switchable RF output power of 1 watt or 25 watts.

The transceiver is capable of RTCM SC101 DSC (Digital Selective Calling) operation.

The transceiver operates on all currently-allocated marine channels which are
switchable for use with either USA, International, or Canadian regulations. It has an
emergency channel 16 w hich can be immediately selected from any chan nel by pressing
the red 16/9 key. NOAA Weather channels can al so be acces sed imm ed iately by pres si ng
the WX key.

Other features of the transceiver include: scanning, priority scanning, submersible mic,
high and low voltage warning, and GPS repeatability.

CONTROLS AND CONNECTIONSCONTROLS AND CONNECTIONS
(1) POWER SWIT CH /VOLUME CONTROL

T urns the transceiver on and off as well as adjusts the audio volume.
T u rn this control clockwise to turn the radio o n and to increase the volume.
Counterclockwise rotation into the c lick-stop will turn the radio off.
Secondary Use
When the transceiver is turned on while the SCAN and WX keys are held down, the
internal microprocessor is reset. This clears the memory and all user-programmed
settings, such as scan memory. This condition is known as the default condition, the
same as when shipped from the factory. For a list of these defaults, see the section
on Resetting the Transceiver’s Microprocessor.
NOTE
Resetting the microprocessor will not erase DSC MMSI and Directory Call
information.

(2) SQUELCH CONTROL (S QL)

Sets the point at which random noise on the channel does not activate the audio
circuits but a received signal does. This point is called the squelch threshold.
Further adjustment of the squelch control will degrade reception of wanted

DSC will eventually replace aural watches on distress frequencies and will be used to
announce routine and urgent m aritime safety information broadca sts.

This new system will allow mariners to instantly send a distress call with GPS position
(when connected to the transceiver) to the US Coast Guard and other vessels within
range of the transmission. DSC will also allow mariners to initiate or receive distress,
urgency, safety routine, POS Request, POS Send and Group calls to or from another
vessel equipped with a DSC transceiver.

It is monitored by the U.S. and Canadian Coast Guards and by other vessels. Use of
channel 16 for hailing must be limited to initial contact only. Calling should not exceed
30 seconds, but may be repeated 3 times at 2-minute intervals. In areas of heavy radio
traffic, congestion on channel 16 resulting from its use as a hailing channel can be
reduced significantly in U.S. waters by using channel 9 as the initial contact (hailing)
channel for non-emergency communications. Here, also, calling time should not exceed
30 seconds but may be repeated 3 times at 2-mi nute intervals.

Prior to making contact with another vessel, refer to the channel charts in this manual,
and select an appropriate c hannel for comm unicati ons after init ial contact. F or exampl e,
Channels 68 and 69 of the U.S. VHF Charts are some of the channels available to non­commercial (recreational) boaters. Monitor your desired channel in advance to make
sure you will not be interrupting other traffic, and then go back to either channel 16 or 9
for your initial contact.

When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish
to call and then “this is” followed by the name of your vessel and your Station License
(Call Sign). When the other vessel returns your call, immediately request another
channel by saying “go to,” the number of the other channel, and “over.” Then switch to
the new channel. When the new channel is not busy, call the other vessel.

After a transmission, say “over,” and release the microphone's push-to-talk (PTT)
switch. When all communication with the other vessel is completed, end the last
transmission by stating your Call S ign and the word “out.” Note t hat it is not necessary
to state your Call Sign with each transmission, only at the beginning and end of the
contact.

Remember to return to Channel 16 when not using another channel. Some radios
automatically monitor Channel 16 even when set to other channels or when scanning;

ABOUT VHF RADIOABOUT VHF RADIO
The radio frequencies use d in the VH F marine band lie between 156 and 158 MHz with
some shore stations available between 161 and 163 MHz. The marine VHF band
provides communications ove r distances that are essent ially “line of sight” (VHF sig nals
do not travel well through objects such as buildings, hills or trees). Actual transmission
range depends much more on antenna type, gain and height than on the power output
of the transmitter. On a fixed mount 25W radio transmission expected distances can be
greater than 15 miles, for a portable 5W radio transmission the expected distance can
be greater than 5 miles in “line of sig ht”.

horizon. The degree to which this is accomplished is called the antenna’s gain. It is
measured in decibels (dB) and is one of the major factors in choosing an antenna. In
terms of effective radiated power (ERP), antennas are rated on the basis of how much
gain they have over a theoretical antenna with zero gain. A 3 foot, 3dB gain antenna
represents twice as much gain over the imaginary antenna. The length of the antenna
you choose, however, must also be related to the size of your boat.

COAXIAL CABLE

.13.13

COAXIAL CABLE COAXIAL CABLE
VHF antennas are connected to the tran sceiver by means of a coaxial cable – a shielded
transmission line. Coaxial cable is specified by it’s diameter and construction.

For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice. For
runs over 20 feet but less than 50 feet, the larger RG-8 or RG-213/U should be used for
cable runs over 50 feet RG-8 should be used. For installation of the connector onto the
coaxial cable refer to the figure below.

To get your coax cable through a fitting and into your boat's interior, you may have to
cut off the end plug and reattach it later. You can do this if you follow the directions that
come with the connector. Be sure to make good soldered connections.
