8 GETTING STARTED

8.1 ABOUT VHF 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 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.

8.2 SELECTING AN ANTENNA

Marine antennas are made to radiate signals equally in all horizontal directions, but not straight up. The objective of a marine antenna is to enhance the signal toward the 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.

Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The longer 8 foot 6dB fiberglass whip is primarily used on power boats that require the additional gain.

3dB

6dB

9dB

Page 10		GX1150

8.3 COAXIAL CABLE

VHF antennas are connected to the transceiver 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-8X should be used.

For cable runs over 50 feet RG-213 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 are supplied with the connector. Be sure to make good soldered connections.

GX1150		Page 11

8.4 EMERGENCY (CHANNEL 16 USE)

Channel 16 is known as the Hail and Distress Channel. An emergency is defined as a threat to life or property. In such instances, be sure the transceiver is on and set to CHANNEL 16. Then use the following procedure:

1.	Press the microphone 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 magnetic bearing (state which) to a well-known landmark such as a navigation aid or geographic feature such as an island or harbour entry.

4.Explain the nature of your distress (sinking, collision, aground, fire, heart attack, life-threatening injury, etc.).

5.State the kind of assistance you desire (pumps, medical aid, etc.).

6.Report the number of persons aboard and condition of any injured.

7.Estimate the present seaworthiness and condition of your vessel.

8.Give your vessel’s description: length, design (power or sail), color and other distinguishing marks. The total transmission should not exceed 1 minute.

9.End the message by saying “OVER.” Release the microphone button and listen.

10.If there is no answer, repeat the above procedure. If there is still no response, try another channel.

8.5 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)

Channel 16 may be used for initial contact (hailing) with another vessel.

However, its most important use is for emergency messages. This channel must be monitored at all times except when actually using another channel.

It is monitored by the European, 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-emer- gency communications. Here, also, calling time should not exceed 30 seconds but may be repeated 3 times at 2-minute intervals.

Prior to making contact with another vessel, refer to the channel charts in this manual, and select an appropriate channel for communications after initial contact. For example, Channels 68 and 69 are some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to make sure you will not be interrupting other traffic, and then go back to either

Page 12		GX1150

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 Sign and the word “out.” Note that 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.

8.6 MAKING TELEPHONE CALLS

To make a radiotelephone call, use a channel designated for this purpose, The fastest way to learn which channels are used for radiotelephone traffic is to ask at a local marina. Channels available for such traffic are designated Public

Correspondence channels on the channel charts in this manual. Some examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call the marine operator and identify yourself by your vessel’s name, The marine operator will then ask you how you will pay for the call (telephone credit card, collect, etc.) and then link your radio transmission to the telephone lines.

The marine telephone company managing the VHF channel you are using may charge a link-up fee in addition to the cost of the call.

8.7 OPERATING ON CHANNELS 13 AND 67

Channel 13 is used at docks and bridges and by vessels manoeuvering in port.

Messages on this channel must concern navigation only, such as meeting and passing in restricted waters.

Channel 67 is used for navigational traffic between vessels.

By regulation, power is normally limited to 1 Watt on these channels. Your radio is programmed to automatically reduce power to this limit on these channels. However, in certain situations it may be necessary to temporarily use a higher power. See page 23 ( key) for means to temporarily override the low-power limit on these two channels.

GX1150		Page 13

Rear Panel

DC INPUT CABLE

Connects the radio to a DC power supply capable of delivering 12V DC.

EXTERNAL SPEAKER CONNECTION CABLE

Connects the GX1150 to an external speaker.

GPS RECEIVER CONNECTION CABLE

Connects the GX1150 to a GPS receiver.

GND TERMINAL

Connects the GX1150 to a good ground, for safety and optimum performance.

Normally, the GND connection to the heat sink is not needed. However, when the DC power cable connection to the radio has a long run, the transmitter may become unstable and the receiving audio may be noisy. In such a case, connect a large diameter, short cable between this terminal on the heat sink and battery ground.

Install only the supplied screw or similar size (M3x6, Stainless Steel) screw.

ANTENNA JACK

Connects an antenna to the transceiver. Use a marine VHF antenna with an impedance of 50 ohms.

11BASIC OPERATION

11.1RECEPTION

1.After the GX1150 has been installed, ensure that the power supply and antenna are properly connected.

2.Turn the VOL/PWR knob clockwise to turn the transceiver on.

3.Turn the SQL knob fully counterclockwise. This state is known as “squelch off”.

4.Turn up the VOL knob until noise or audio from the speaker is at a comfortable level.

5.Turn the SQL knob clockwise until the random noise disappears. This state is known as the “squelch threshold.”

6.Press the or keys to select the desired channel. Refer to the channel chart on page 70 for available channels.

7.When a message is received, adjust the volume to the desired listening level. The “” indicator on the LCD is displayed indicating that the channel is being used.

11.2 TRANSMISSION

1.Perform steps 1 through 6 of RECEPTION.

2.Before transmitting, monitor the channel to ensure it is clear.

THIS IS AN FCC REQUIREMENT!

3Press the PTT (push-to-talk) switch. The “” indicator in the LCD is displayed.

4. Speak slowly and clearly into the microphone.

NOTE

This is a noise cancelling microphone. The oval slot on the microphone should be positioned within 1/2 inch (1.3 cm) from the mouth for optimum performance.

5. When the transmission is finished, release the PTT switch.

11.3 TRANSMIT TIME - OUT TIMER (TOT)

When the PTT switch on the microphone is held down, transmit time is limited to 5 minutes. This limits unintentional transmissions due to a stuck microphone.

About 10 seconds before automatic transmitter shutdown, a warning beep will be heard from the speaker(s). The transceiver will automatically go to receive mode, even if the PTT switch is continually held down. Before transmitting again, the PTT switch must first be released and then pressed again.

NOTE

When a transmission was shut down by the TOT, the GX1150 can not transmit afterwards for 10 seconds.
