2.3 PLANNING THE INSTALLATION

When planning the installation for your RAY210, the following conditions

should be considered to insure dependable and trouble-free operation.

1) The mounting location should be easily accessible to allow operation of the

front panel.

2) There should be adequate ventilation.

3) A sufficient space should be secured behind the transceiver to allow cable

connections to the rear panel connectors.

4) The transceiver should be located near a power source.

5) The selected location should be far enough away from devices that may cause

interference, such as motors and generators.

6) Generally speaking, the transceiver should be protected from prolonged direct

exposure to rain and salt spray. It is a good practice to protect your valuable

electronic equipment as much as possible.

The RAY210 can be conveniently mounted on a chart table, bulkhead, overhead

or any other desired location.

2.4.1 DC Power and External Speaker Connections

The 6 foot long power cable assembly consists of the DC power and the external

speaker cable. The DC power cable is composed of RED (+) and BLACK (-)

wires, and the external speaker cable has YELLOW (+) and GREEN (-) wires.

The RED (+) wire with an in-line fuse (10 amps.) and the BLACK (-) wire of

the 4 pin connector cable are used for connecting the RAY210 to the ship's 12

VDC power system. (refer to fig 2-4)

Fig 2-4 POWER / EXTERNAL SPEAKER CABLE AND 4PIN CONNECTOR

CABLE

In most cases this length should be adequate enough to reach the DC power

source. If additional wire length is required, the cable can be extended by adding

more cable as necessary. However, for power cable runs longer than 15 feet,

larger wire diameter size should be used to prevent voltage line loss. Fig 2-5

provides recommended wire sizes to use for various cable run distance.

Fig 2-5 POWER CABLE LENGTH

Your RAY210 radio should be connected to the nearest primary source of ship's

DC power. A typical source may be a circuit breaker on the power panel or a

fuse block near the unit. When connecting to either of these sources, the circuit

breaker or other in-line fuse should be rated at 10 amps.

Download from Www.Somanuals.com. All Manuals Search And Download.

It is recommended that lugs be used to connect the power cable to the DC

supply and that lugs should be both crimped and soldered. This is very important

in order to insure adequate current draw to the equipment. Intermittent operation

may result if an insufficient connection is made to the power source. The

connection terminals should be clean, with no sign of corrosion.

The RED (+) wire is connected to the positive terminal of the power source or

battery. The BLACK (-) wire is connected to the negative (ground) of the power

source or battery. Should the power connector be inadvertently reversed, the 10

amp. in-line fuse located in the RED (+) wire will open. Check the input power

leads for correct polarity with a VOM (volt /ohm meter), reconnect the leads

observing correct polarity, and replace the fuse. Use the same rate and type fuse.

2.4.2 External Speaker Connections

The YELLOW (+) wire and GREEN (-) wire are used for connecting the

RAY210 to the external speaker. (Refer to Fig 2-4)

Four watts of audio output is provided for an external 4 ohm speaker. A suitable

speaker can be purchased from your local marine dealer.

Connect the YELLOW (+) wire and GREEN (-) wire with the speaker. The

internal speaker and the external speaker will sound simultaneously.

2.4.3 Antenna Connections

The coaxial cable to your VHF antenna is intended to be connected to the

antenna jack on the rear panel using a PL259 VHF type connector. The antenna

cable may be cut to the required length at installation. If a longer cable length is

required, RG-58 50-ohm coaxial cable or equivalent cable may be used for runs

up to a maximum of 50 feet. If the distance required is even greater, then we

recommend using low loss RG-213 or equivalent cable for the entire run in

order to avoid excessive losses in power output.

If the antenna connector is likely to be exposed to the marine environment, a

protective coating of grease (similar to Dow Corning DC-4) can be applied to

the connector before connecting it to the radio. Any other extensions or adapters

in the cable run should also be protected by silicon grease and then wrapped

with a waterproofing tape.

2.4.4 Antenna Mounting Suggestions

The best radio in the world is useless without a good antenna location. Mounting

the VHF antenna properly is very important because it will directly affect the

performance of your VHF radio. A standard VHF antenna that is designed for

use aboard boats should be used.

Download from Www.Somanuals.com. All Manuals Search And Download.

There are several factors to consider in order to maximize the effective

communication range of the radio.

• Since VHF transmissions are essentially Line-of-Sight, mount the antenna at

the highest possible location on the vessel and free of obstruction in order to

obtain maximum range.

• Use an antenna with the highest possible gain characteristics.

• If you must extend the length of the coaxial cable between the antenna and

the radio, use a coaxial cable designed for the least amount of power loss over

the entire cable length.

• Keep the coaxial cable between the radio and antenna as short as possible.

2.4.5 Grounding

While special grounding is not generally required to VHF radiotelephone install-

ations, it is a good marine practice to properly ground all electronic equipment

to the ship's ground system. The RAY210 can be connected to ground by attach-

ing a wire to one of the RF connector screws on the unit's rear panel and then to

the nearest ship's ground connection point. The recommended wire to be used

for such grounding is #10 AWG.

The RAY210's cabinet was specifically designed and die-cast from aluminum to

insure maximum noise rejection from external sources.

SECTION 3

OPERATIONS

3.1 INTRODUCTION

Your RAY210 has the capability to transmit on 51 and receive on 93 Marine

VHF radiotelephone channels. There are channels that are FCC approved but

may only be used by authorized stations for specific purposes, depending on the

type of vessel (commercial or non-commercial). Take a look at Table 3-1 and 2

on page 22-24 which lists all of the marine VHF channels available in your

RAY210 for International and U.S. radiotelephone use. Full familiarization with

this table is essential when selecting your channels. The international

frequencies were agreed upon by the attending countries at the 1968

International Telecommunication Union Meeting in Geneva and are in active

use around the world. The U.S. channels are those channels authorized for use in

the U.S.A. by the FCC.

3.2 CONTROLS AND LCD DISPLAY

Refer to Figure 3-1 for familiarization with the controls and mode display.

3.2.1 Controls

1) On / Off and Volume Control:

This control switches the RAY210 on and off and controls the volume level of

the internal speaker. Turning the radio On will apply power to the radio

circuitry. When the radio is on, rotating this control clockwise will increase

volume to the internal speaker and rotating this control counterclockwise will

decrease volume.

2) CHANNEL Selector Control

This control selects the desired operating channel. When the control is turned in

a clockwise direction, the channel number increases. When the control is turned

in a counterclockwise direction the channel number decreases.

3) SQUELCH Control

Provides an adjustable input signal threshold to eliminate random RF

background noise during “no signal” conditions. This control sets the signal-to-

noise ratio at which a signal will become audible.

4) [16/9] Key

Used to select channel 16 or 9 immediately. This Key enables the following

operating mode;

At the time of shipment

Press for more than 3 sec

Press for more than 6 sec

Press for more than 9 sec

: n

(n = The Previously Monitored Channel)

This key is operative any time and will stop All Scan or Select Scan when

pressed.

5) [FUNC] (Function) Key:

When the [FUNC] key is pressed, an F will appear on the LCD to let the

operator know that a Secondary Function can be selected. To operate a

secondary function, first press the [FUNC] key, then press the desired front

panel key. To cancel a secondary function and return to the previous operating

mode, repeat the same procedure.

The function key enables the following operating modes and operations when

the associated keys are depressed:

• All Scan Mode - press [FUNC] then [SCAN] : SCAN will be displayed on

the LCD.

• TX Power setting mode - press [FUNC] then [1/25] :1W will be displayed on

the LCD.

• DWX mode - press [FUNC] then [DWX] : DWX will be displayed on the

LCD.

• MEM mode - press [FUNC] then [MEM] : MEM will be displayed on the

LCD.

• International mode - press [FUNC] then [INTL] : INTL will be displayed the

LCD.

6) [SCAN] (All Scan) Key:

This key is used as a secondary function to activate the all scan mode. To

activate the all scan mode, press the [FUNC] key, then [SCAN]. SCAN will be

displayed on the LCD and the RAY210 will sequentially scan all USA or INTL

channels (CH 01- CH 88, See Table 3-2 page 23 and 24) except weather

channels. To cancel the scan function, press the [FUNC] key then [SCAN].

• If signal is present on the channel that is being scanned, the scanning will

stop until the station clears. After the station clears and no signal is received for

five seconds, the scanning will resume. Pressing [SC] (scan continue) will

reactivate the scanning if the radio has stopped on a particular channel and the

operator wants to continue.

Download from Www.Somanuals.com. All Manuals Search And Download.

• If the radio has stopped on a channel, and the operator wants to transmit on

that channel, pressing the PTT switch will cancel the scan function and the

RAY210 will remain on that channel.

• If the radio stops on a channel during the scan mode due to a received signal,

the operator can cancel the scan function and the RAY210 will remain on that

channel. If no signal was present when the All Scan is deactivated, the radio will

revert to the channel in use prior to the selection of All Scan.

When the radio is in the All Scan mode, the keyboard is inoperative except for

the following keys: [SC], [DIM], [VOLT], and [16]. The transmitter is inhibited

in the All Scan mode.

NOTE: During scanning operations, a VHF radio will sometimes stop on a

particular channel for no obvious reason. This can be caused by electrical noise

and interference that may be common to a particular port or harbour area.

7) [1/25] (high / low power) key:

This secondary function is used to toggle the transmit power setting between 25

watts and 1 watt. To set the transmitter to low power setting (1 watt), press the

[FUNC] key, then [1/25]. 1W will then be displayed on the LCD and your

RAY210 will apply approximately 1 watt of power to the antenna during

transmit operation. When 1W is not displayed on the LCD, the radio is set to

provide 25 watts of power to the antenna. The low power setting is provided for

situations where the parties communicating are close to each other. This reduces

radio channel congestion in distant areas, allowing more individuals to use the

same channel at a given time.

Some VHF channels are required by the FCC to be automatically set to transmit

on low power (Refer to Table 3-2 on pages 23 and 24). The operator may

override this automatic setting on some of these channels. To override the

automatic low power setting on authorized channels, press the [FUNC] key then

[1/25] key and hold.

8) [DWX] (Dual Watch Plus Weather) Key:

This secondary function key activates Dual Watch plus Weather Mode and

illuminates the DWX symbol on the LCD. In this mode, the RAY210 will scan

(monitor) priority channel 16, a user selected channel, and selected weather

channel (monitor weather alert warnings). To operate this mode, first select a

working channel, then select a weather channel by pressing the [WX] key and

set to desired channel. Pressing [FUNC] key and then the [DWX] key will

activate the DWX mode. Pressing the [FUNC] and then the [DWX] key again

cancels the DWX mode.

Download from Www.Somanuals.com. All Manuals Search And Download.

• If a signal is received on either channel 16 or the selected working station

while in the DWX mode, the operator can communicate with the calling party

and still remain in this mode.

• If a weather warning is received on the weather station being monitored, the

RAY210 will emit a series of tones. The radio will then automatically switch to

the WX mode in order to monitor the emergency broadcast.

The radio will no longer be in the DWX mode.

9) [MEM] (Memory) key:

This secondary function key stores channels into memory for select scan

functions. To store a channel using the memory, select the desired channel using

the selector knob, press the [FUNC] key, then [MEM]. The MEM symbol will

illuminate on the LCD and the displayed channel will be stored into memory.

The same procedure is used to remove a channel from memory. To view all

channels that are stored in memory, press the [RCL] key. RAY210 will display

each channel in memory, then return to the previously selected channel.

10) [INTL] (International) key:

This key causes the synthesizer to program international frequencies and

illuminates the INTL symbol on the LCD. To change to international

frequencies, press [FUNC] key, then [INTL]. To return to U.S. channel

frequencies, repeat this same procedure.

11) [WX] (Weather) key:

When pressed, puts the radio into the weather receiving mode. A WX indicator

will be displayed on the LCD along with the weather channel number (0-9).

Rotate the channel selector knob until the desired WX channel is displayed.

Refer to Table 3-1 (page 22) for weather channel frequencies. Pressing the [WX]

key a second time returns the RAY210 to the operating channel previously used.

12) [DW] (Dual Watch) key:

Pressing this key puts the radio into the Dual Watch mode and DW is

illuminated on the LCD. The RAY210 will then monitor the current selected

channel and channel 16. If a signal breaks squelch on either channel, the radio

will change to that channel. After the channel clears, and no transmission is

received for five seconds, the radio will return to the Dual Watch operation.

13) [SC] (Scan Continue) key:

During scanning mode, if a signal breaks squelch on a certain channel, the

scanning will stop on that channel. Pressing the Scan Continue [SC] key will

resume the scan operation.

14) [SS] (Select Scan) key:

Pressing this key puts the radio into the Select Scan Mode, and MEM SCAN

will be illuminated on the LCD. In this mode the RAY210 will scan only those

channels which have been stored into memory by the operator.

• If a signal breaks squelch during the scan operation, the radio will stop on

that channel and will resume scanning only after a signal is no longer received

and the channel remains clear for five seconds.

• If a signal breaks squelch during the scan operation and you wish to comm-

unicate with the other party, when the PTT switch is depressed, the scan mode

will deactivate and the radio will operate normally on the channel.

If a signal is present when the Select Scan is deactivated, the radio will remain

on that channel. If no signal is present when the Select Scan is deactivated, the

radio will revert to the channel in use prior to the selection of the Select Scan

Mode.

When the radio is in the Select Scan mode, the only keyboard buttons that pre-

empt the scan are [SS] and [16]. Note that two separate sets of programmed

memory channels are possible, one set of International channels and one set of

USA channels. The transmitter is inhibited in the SS mode.

15) [M1] through [M5] "quick" memory keys:

Using these keys, the operator can store up to five channels in memory for quick

and convenient access any time. To store a channel in the Ml through M5 quick

memory:

• Select the desired channel with channel selector knob.

• Press and hold the desired quick memory key for approximately three

seconds until two beeps are heard.

• The memory location number will then be displayed on the LCD.

16) [RCL] (Memory Recall) key:

When this key is pressed, the RAY210 will display each of the channels that are

currently stored in memory for the Select Scan mode.

Upon completion, the radio will return to the previously selected channel.

3.3 OPERATING PROCEDURES

Specific operating procedures for the RAY 210 are presented on this section.

General information regarding correct marine channel usage may be found in the

Appendix section. Refer to the Controls section 3.2.1 beginning on page!2 for a

thorough description of all functions.

3.3.1 Turning the power on ( Transmit/Receive)

Turn the ON/OFF/Volume control to switch the radio on. Rotate the knob

clockwise and set it at approximately the mid point of it's range.

3.3.2 Setting the volume

Rotate the Squelch control fully counterclockwise, and set the ON/OFF/Volume

control to the desired listening level.

3.3.3 Setting the Squelch

Rotate the Squelch control clockwise until the receiver becomes "quiet" and the

audible noise coming from the internal speaker ceases.

3.3.4 Selecting a Channel

Rotate the channel selector switch to the desired channel. See Table 3-2 (Page

23 and 24) for available U.S.A. and International channels and their frequencies.

To transmit and receive on channel 16/9, press the "quick" 16/9 key. If the

[16/9] is pressed again, the RAY 210 will return to the previous channel.

NOTE: Initial communication contacts are usually made on channel 16 as all

ships and shore stations monitor this channel. Then switch to a working

frequency for general communications.

3.3.5 Setting the Power Output

Press the [FUNC] and then the [1/25] key to select the power output. Power

setting is dependent on the distance the message is to be transmitted, and

transmitting conditions. In certain U.S. harbours and on certain channels, the

FCC requires the power to be limited to 1W. On these "required" channels, the

RAY 210 automatically selects 1 watt operation when the channel is selected

1W will appear beside the channel number.

3.3.6 To Transmit

To transmit, press the Push-To-Talk switch on the side of the RAY 210

microphone. Speak into the microphone using a clear, normal voice.

The RAY 210 is designed to meet the FCC Rules Part 80.203. This rule requires

transmitter time out circuitry which will automatically disable the transmitter

after 5 minutes of continuous transmit.

Download from Www.Somanuals.com. All Manuals Search And Download.

After 4 minutes of continuous transmit, the RAY 210 will emit two warning

tones. If the transmitter remains engaged for an additional minute, or 5 minutes

total, the RAY 210 will automatically disable the transmit operation.

At this time, the RAY 210 will cease transmitting, emit an alarm, and “ot” will

be displayed on the LCD. To return to normal operation, the microphone FIT

switch must be disengaged.

3.3.7 To Transmit and Receive on INTL Frequencies

To transmit and receive on International frequencies, press the [FUNC] and then

the [INTL] key, then select the desired channel. INTL will appear on the display

to indicate International operation.

3.3.8 Selecting a Weather Channel

To select and receive a weather channel, press the [WX] key and then rotate the

channel selector switch to the desired channel (0-9). Refer to the below Table 3-

1 for specific weather channel frequencies. When in the weather mode, the

transmitter is disabled.

SECTION 4

TECHNICAL

4.1 RECEIVING CIRCUIT OPERATION:

4.1.1 Antenna Switching Circuit:

A signal received at the antenna connector J1 goes to the antenna switching

circuit composed of pin diode Dl and D2 via the low pass filter.

4.1.2 High Frequency Amplifier Circuit:

After being amplified by transistors RF AMP1 (Q21) and RF AMP2 (Q22),the

high frequency signal which is sent from the antenna switching circuit goes

through BPF to suppress the undesired signals . Then the high frequency signal

is added to the 1st mixer of the next step diode (D15, D16).

A local oscillating signal from PLL unit (134MHz range) is input to this 1st

mixer, mixed with the receiving signal to make the 1st intermediate frequency

(21.6MHz).

4.1.3 1st Intermediate Frequency Amplifier Circuit

After undesired signals have been removed by a pair of crystal filters (FIL101),

the 1st intermediate frequency signal generated in the 1st mixer is amplified at

the 1st IF AMP (Q30).

4.1.4 2nd Intermediate Frequency Circuit:

The 1st intermediate frequency signal is added to IC307, which is composed of a

local oscillating circuit, a mixer circuit, a limiter amplifier circuit, a

remodulation circuit and a squelch circuit.

The 1st intermediate frequency signal is converted to 455KHz 2nd intermediate

frequency signal after being mixed with 21.145MHz signal which is output from

the local oscillating circuit in IC307 and a crystal oscillator (XTAL4). Undesired

signals are removed from this signal by a ceramic filter (FIL3), and the signal is

subjected to amplification in the limiter amplifier circuit.

The amplified 2nd intermediate frequency signal is re-modulated by the re-

modulation circuit composed of a circuit in the IC307 and a ceramic

discriminate element (FIL4).

Then it is output as a low frequency signal.

Download from Www.Somanuals.com. All Manuals Search And Download.

4.1.5 Low Frequency Circuit:

The low frequency signal re-modulated by IC307 obtains -6dB/oct characteristic

by going through the de-emphasis circuit which contains BUFF (IC13A) and

LPF (Q25). Then the signal is input to the low frequency section of CPU AF

board.

4.1.6 Squelch Circuit:

If no signal is input to the antenna, noise signal is amplified by the amplifier (IC

13B), As the result of receiving the amplified noise signal, the squelch circuit of

IC307 outputs BUSY signal. Squelch level is controlled by VR101.

4.1.7 Low Frequency Treatment Circuit (CPU AF Board):

The re-modulated low frequency signal is amplified in AMP (Q7). Its volume

can be adjusted by the tone volume (VR 102).

BUSY signal, output from the squelch circuit (6), becomes a MUTE signal after

being conditioned in CPU circuit. The low frequency signal is turned on and off

by the transistor switch (Q6) which is driven by this MUTE signal.

The low frequency signal further undergoes power-amplification in the low-

frequency-power-amplifier (IC 305) to drive the speaker. With the amplifier

circuit (IC6, Q8, Q10), which drives the microphone speaker, it is possible to

monitor the receiving tone heard from the microphone speaker. This driving

circuit can be turned on and off by key operation.

4.1.8 WX Alert Detection:

The tone selector (IC10 RF Board) detects the 1050Hz alert tone if it is

contained in the re-modulated receiving signal. The operating mode is changed

to WX receiving mode when CPU confirms that the alert tone has been detected.

4.2 TRANSMITTING CIRCUIT OPERATION

4.2.1 Microphone Amplifier Circuit:

Voice signal from the microphone is amplified by TX MIC AMP (IC5AJC5B)

in the CPU AF Board. At the same time, the voice signal obtains pre-emphasis

characteristic of 6 dB/oct in the range from 300Hz to 3KHz. The oscillation

width of this signal is limited by LIMITER circuit (D5) of the RF board. The

harmonic wave distortion generated by this oscillation width limitation is

removed by TX MOD LPF (IC31). Then the voice signal is input to VCO

section of PLL circuit as a modulation signal. This modulation signal frequency

is modulated directly by the variable capacity diode D11 of VCO.

Download from Www.Somanuals.com. All Manuals Search And Download.

4.2.2 High Frequency Power Amplifier Circuit:

When the mode turns to be in a state of transmitting by turning the PTT switch

of the microphone, frequency of PLL is set up to the transmitting frequency .The

range of oscillation frequency of VCO is shifted by this transmitting/receiving

shift circuit (Q31). This high frequency signal of VCO undergoes the

amplification in the buffer amplifier Q17 and driving amplifiers Q4, Q3. After

being power-amplified to a maximum output power of 25W by the power

module (IC1), it is transmitted as a transmitting output power from the antenna

connector J1) via the antenna switching circuit

4.2.3 APC Circuit:

The output power is detected as a direct current signal by APC detecting circuit

(D3). APC control circuit composed of Q1, Q2 and IC2 controls the transmitting

output power, together with 25W/1W switching circuit (Q5).

4.2.4 Antenna Monitoring Circuit:

After passing through LPE which depresses harmonic waves, the amplified

transmitting output power is outputted as an antenna output power via a split

line on the PC board pattern and an antenna monitoring circuit composed of

D311 and D312. After being detected at D311 and D312, the direct current

signals are amplified at SWR REF AMP (IC30B) and SWR FWD AMP

(IC30A) respectively. Then they are converted to digital signals by the A/D

converter in CPU. The antenna monitoring circuit always watches the condition

of the antenna by observing these digital signals.

If the antenna is normal:

VSWR - R < VSWR - F

If the antenna is open or short:

VSWR - R ≥ VSWR - F

4.3. PLL CIRCUIT OPERATION

The oscillation circuit of PLL IC (IC9) oscillates 12.8MHz frequency by the

crystal oscillator (XTAL1) attached to it. This 12.8MHz frequency is divided

into 1/512 by the divider inside the IC to make 25KHz frequency, which is the

reference frequency of PLL. Frequencies are set up at the time of transmitting

and receiving respectively by data from CPU (DATA, CLK, STB). Error signals

from PLL pass through the loop filter (LPF). Frequencies of these error signals

are controlled by variable capacity diode (DIG) of VCO (Q15).

Frequency: 162.550MHz with no modulation

Output level: 60dB µ

2) Select the weather channel WX1.

3) Connect a frequency counter to TP1 on the RF Board and adjust RV6 to

obtain 1050kHz +/-5Hz on the frequency counter.

5.4 TROUBLE SHOOTING GUIDE

Table 5-4 provides a general trouble-shooting chart for use by a technician to

isolate circuitry failures to specific functional areas within the RAY 210.

5.4.1 Master Reset

The first step in attempting to clear a problem associated with the general

operation of this radio is to perform a MASTER RESET. This can be done by

pressing the [FUNC] and [16] keys simultaneously, and while holding, turning

the power on. This should be performed anytime a component or PCB within the

radio is replaced. This function will clear the RAY210 memory and will return it

to its factory settings.

It should be noted that micro-components within the radio are generally not field

replaceable, therefore, repairs to the radio typically go down to the board level

only. A replacement parts list for the RAY210 can be found in Section 6.

SECTION 7

APPENDIX

7.1 VHF MARINE CHANNEL USAGE GUIDE AND LICENSING

REQUIREMENTS

Most of the information found in this section is reprinted in whole or in part from

FCC Information Bulletin No. 2 February 1991 and FCC Fact Sheet PR-5000 March

1990.

REMEMBER:

• Maintain a radio watch on Channel 16. Channel 16 is for distress and purposes

only.

• Use VHF Channel 70 only for Digital Selective Calling (DSC), It may be for gen-

eral-purpose calling using DSC. Your cooperation in not using Channel 70 for

intership communications is necessary to prevent interference.

• Your VHF transceiver has a high-low power switch. Use low power whenever

feasible. Unnecessary high-power operations can interfere with other important

communications

• Always use your radio call sign at the beginning and end of each transmission.

• Be sure only qualified persons operate your radio. You are responsible for control

of your radio. Know the rules.

• Limit calls to other vessels to 30 seconds. If you receive no reply, wait 2 minutes;

then try again. Keep communications brief and avoid chit-chat.

• Never transmit false distress and never use profanity on the air.

OTHER REMINDERS

“The FCC has revised its policy on radio licensing requirements for certain ships and

stations in the 1996 Telecommunications Act Maritime Provisions (FCC96-145).

This new rule eliminates the individual licensing requirement for recreational ships

and private aircraft operating domestically which are not required by law to carry a

radio. But, the operator is still bound to abide by the FCC rules governing the

operation of a marine VHF transceiver and is subject to the penalties for non-

compliance. Even though the station license is now not mandatory for recreational

boaters, we still strongly recommend that one be obtained. The FCC station license

application fee is $75.00 and the license term is 10 years. If you plan to dock in a

foreign port or leave a foreign port to dock in a U.S. port, however, you will need a

station license as well as a radio operator license to operate a VHF marine radio.”

Download from Www.Somanuals.com. All Manuals Search And Download.

• Your radio license is not transferable. If you sell your boat, request the FCC to

cancel your station license.

If you replace your radio, you do not need to change your license unless the new

radio operates on another frequency band. If you install equipment to operate on

another frequency band, apply for modification of your license.

• If you carry more than six passengers for hire, your vessel must be certified as a

passenger-carrying vessel by the FCC and the Coast Guard.

Licensing Options for Hand Held Portable VHF Marine Transceivers 10 Watts

Power or Less

VHF Marine hand held transceivers can be operated and licensed as follows:

a) Associated Ship Unit:

A hand held VHF Marine transceiver can be operated under an existing valid

ship station license under the following conditions only:

i) Except for safety purposes, the hand held transceivers must be used only to

communicate with the ship station with which it is associated. Such associated

ship units MAY NOT be operated from shore.

ii) The transmitting power is limited to ONE WATT only.

iii) The hand held transceiver must be identified by the call sign of the ship

station along with its associated unit designator.

b) Portable Ship Station:

The Commission may grant a station license permitting operation of a portable

ship station aboard different vessels of the United States. Each application (FCC

Form 506-Application for a Ship Radio Station License) for a portable ship

station license must include a showing that:

i) The station will be operated aboard aboard a vessel.

ii) A station license for portable equipment is necessary to eliminate separate

applications to a ship station aboard different vessels.

Download from Www.Somanuals.com. All Manuals Search And Download.

c) Marine Utility Station:

A utility station in the maritime mobile service consists of one or more hand

held transceiver units licensed under a single authorization. Each unit is capable

of operating while being hand carried by an individual. There are two types of

stations authorized:

i) Marine Utility Coast- when transmitters are located on land; may

communicate directly to vessels only.

ii) Marine Utility Coast/Ship- transmitters from land may communicate with

vessels or when aboard a vessel, may communicate with other vessels or coast

stations.

NOTE: A Marine Utility Ship license will not be authorized.

The station operates under the rules applicable to a private coast station when the unit

(s) are on land and under the rules applicable to a ship station when the unit(s) are

aboard a vessel. FCC Form 503, application for Land Radio Station License is used

when applying for a marine utility License.
