2.3 PLANNING THE INSTALLATION

When planning the installation for your VHF5200, the following conditions should be considered to insure dependable and trouble-free operation.

The mounting location should be easily accessible to allow operation of the front panel.

There should be adequate ventilation for the control unit.

A sufficient space should be secured behind the transceiver to allow for proper cable

connections to the rear panel connectors.

The transceiver should be located as

The selected location should be as far apart as is possible from any devices that may cause

nearto

the power source as possible.

interference such as motors, generators, and other on board electronics.

Generally speaking, the transceiver should be protected from prolonged direct exposure to rain and salt spray. as much

Use adequate sized wire for all DC power connections and make sure to solder all in-line

possible.

It is always a good practice to protect your valuable electronic equipment

connectors or splices.

2.3.1 Typical Mounting Methods

The VHF5200 can be conveniently mounted on a chart table, bulkhead, overhead, or any other desired location. (Refer to Figure 2-1 for typical mounting methods)

Fig. 2-1 TYPICAL MOUNTING METHODS

2.3.2 Flush Mounting In addition to the Typical Mounting Methods, the VHF5200 may also be flush mounted using the

optional Flush Mount kit (M99-113). These kits are available from your Apelco dealer or our Customer Service Department.

1) Select the location for the VHF. A clear, flat area, of sufficient height having at least 6” of clear depth behind the panel is required.

2) Unpack the Flush Mount kit and confirm that all hardware is present.

3) Place the ring at the desired location on the panel. Using the inside of the trim ring, trace

a cutout guide. Remove the trim ring.

4) Drill a pilot hole inside of the cutout guide area.

5) Using an appropriate saw, cut along the outside of the cutout line.

6) Remove the yoke knobs and the bracket from the VHF cabinet. Check that the VHF will

fit into the cutout area.

7) Install the power and antenna cables in the console.

8) Insert the trim ring in the console cutout and secure in place with the countersunk flat

head screws. A suitable sealant may be used between the trim ring and console to prevent moisture entry. Position the radio in the trim ring and secure in place with the two

hex-head bolts and washers supplied.

9) Connect the power/external speaker and antenna cables.

CAUTION

Make sure there are no hidden electrical wires or other items behind the desired location

before proceeding.Check that free access for mounting and cabling is available.

In most cases, the length of the supplied cable should be adequate 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 line loss. Fig 2-5 provides recommended wire sizes to use for various cable run distances.

Fig. 2-6 POWER CABLE LENGTH

Your VHF 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 located near the

unit. When connecting to either of these sources, the circuit breaker or other in-line fuse

should be rated at 10 amps.

It is recommended that terminal lugs be used to connect the power cable to the DC supply and that the lugs should be both adequate current draw to the equipment. Intermittent operation may result if an inadequate connection is made to the power source. The connection terminals should be clean and 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 polarity be inadvertantly reversed, the 10 amp. in-line fuse located in the RED (+) conductor will open. Check the input power leads for correct polarity with a VOM, reconnect the leads observing correct polarity, and replace the fuse. Be sure to use the same rate and type of fuse.

2.4.2 External SpeakerConnections

The YELLOW (+) wire and GREEN (-) wire are used for connecting the VHF5200 to an external speaker. (Refer to Fig. 2-4)

Three 3 watts of audio output power 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 marked on the speaker. When connected, the external speaker will function simultaneously

2.4.3 AntennaConnections

The coaxial cable from your VHF antenna is intended to be connected to the antenna jack on the rear chassis using a PL259 VHF-type connector. The antenna cable may be cut to desired length. If a longer cable length is required, RG-58 50-ohm coaxial or equivalent cable may be used for antenna 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 continuously exposed to the marine environment, pro-

tective coating of silicon grease (similar to Dow Corning DC-4) can always be applied to the

connector before mating it to the radio to help prevent corrosion. Any other extension or adapters in the cable run should also be protected by silicon grease and then wrapped with a

weather-proofing 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 how it is mounted will directly affect the performance of your VHF radio. A standard VHF antenna which is designed for use aboard water craft should be used.

There are several factors to consider so as to maximize the effective communication range of the radio.

SinceVHF transmissions are essentially Line-of Sight, mount the antenna at the highest possible

location on the vessel. The location should also be free of obstructions 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 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.

214.5

Grounding

While special grounding is not generally required for VHF radiotelephone installations, it is a good marine practice to properly ground all electronic equipment to the ship’s ground system. The VHF5200 can be connected to ground by attaching a wire to the screw indicated in the drawing below and then to the nearest ship’s ground connection point. The recommended

wire to be used for grounding is #I 0 AWG.

OPERATIONS

3.1 INTRODUCTION

Your VHF5200 has the capability to transmit on 53 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 noncommercial). Refer to Table 3-l on pages 16 and 17. These tables list all of the marine VHF channels available in your VHF5200 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.

memorized will be scanned in the Memory Scan mode.

1) Channel Memory: To put a channel into memory, simply select the channel to be stored with the Up or Down arrows. Push and hold the “SCAN” key for approximately two seconds until a

“beep” is heard and “MEMORY” is displayed on the LCD. This procedure can be repeated for all U.S. or International channels.

2) Memory Clear: To clear a channel from memory, select the channel to be cleared with the Up or Down arrows. Press and hold the “SCAN” key for approximately two seconds until a “beep”

is heard and “MEMORY’ disappears from the LCD.

3.3.4 Scan Modes

The VHF5200 is equipped with two types of scan options, All-Scan and Memory Scan. How these options are accessed is dependent upon whether there are any channels stored in memory.

1) All-Scan mode

If no channels are stored in memory, when the SCAN key is pressed once, “SCAN” will begin to flash on the LCD. In three seconds, if no other keys are pressed, the radio will begin scanning all channels (except weather channels) as long as no signal is received. If a signal

is received, the scan will stop and monitor the receiving channel. If the signal is lost for five

seconds, the radio will resume scanning. If the scan has stopped on a received signal, you

may resume scanning by pressing the SCAN key. To cancel the scan mode, press the

SCAN key once while the radio is scanning.

2) Memory Scan mode If one or more channels are stored in memory, when the SCAN key is pressed, “SCAN” and

“MEMORY” will begin to flash simultaneously on the LCD. If no other key is pressed, the

radio will begin scanning all channels currently in memory in three secondsAs with All-

Scan, if a signal is received, the scan will stop on the receiving channel until the signal is lost

for five seconds or the SCAN key is pressed. To cancel memory scan, press the SCAN key

while the radio is scanning. If you have one or more channels in memory and want to initiate Ail-Scan, perform the following:

Press the SCAN key. “SCAN” and “MEMORY’ will flash on the LCD. Press the SCAN key again within three seconds and “MEMORY’ will disappear from the LCD leaving only “SCAN” flashing. All-Scan will begin in three seconds if no other key is pressed.

3.3.5 Master Reset To perform a master reset, press and hold the 16 PLUS key while turning the unit on. This feature

clears all channels from memory and programs the 16 PLUS feature back to channel 16.

3.3.6 Monitor Mode

Before entering the Monitor Mode you must first select the WX channel you wish to monitor for

the weather alert tone. Next, you must also select a working channel to be monitored for traffic.

(Refer to section 3.3 for instructions on channel section) For this example, we will use channel 83 as our working channel and

key and the radio will begin to scan the channel designated for 16 PLUS, 83, and WX2, repetitively. monitored channels. To cancel the Monitor mode, press the MON/1/25 key again.

SECTION 4

TECHNICAL DESCRIPTION

4.1 GENERAL

The VHF5200 can be considered as consisting of two major sections. They are:

The Control Circuitry (consisting of the front panel controls, the LCD display, control

CPU).

l The

Transmitter/Receiver/PLL

circuits.

4.2 THE CONTROL SECTION

The heart of the control section is the CPU, IC201, located on the main PCB. The CPU controls all of the following items:

Controls the Squelch circuit by detecting a busy signal from the second IF circuit

Generates a beep tone when a key is activated on the keyboard.

Mutes the transmitter modulation circuit when receiving.

Controls the output power of the transmitter High/Low.

Controls the dividing ratio N of the PLL circuit.

Switches On/Off the transmitter power.

Mutes AF audio.

Detects a weather alert signal (when in Monitor Mode).

IC5.

Controls the LCD display.

4.3 THE

TRANSMITTERIRECEIVERPLL

SECTION

In reading through the following circuit descriptions, it may be helpful to refer to Figure 4-l Block Diagram of the TX/RX/PLL circuits.

4.3.1 PLL (Phase Lock Loop Circuit)

The PLL circuit is the frequency synthesizer in the VHF5200.

The reference frequency of 12.8 MHz is provided by crystal

XTLI

and IC3. IC3 contains the reference oscillator (12.8 MHz) circuit, the phase comparator, the program counter and the phase detector. The 12.8 MHz reference signal is divided by 512 in the program counter in IC3 to obtain a 25 KHz reference signal. The dividing ratio is determined by CPU

IC201.

output from oscillator Q4 is amplified by buffer amplifier Q3, and returned to IC3 and is divided by the dividing ratio N to obtain a 25 KHz signal. N for 1 N in lC3 is determined by CPU Both of these

25KHz

signals are fed into the phase comparator circuit of IC3.

The phase detected signal, obtained by comparing the phase difference between these two

signals, is applied to LPF between pins 11 and 12 of IC4 to get a DC voltage correlated with the phase difference.

The DC voltage acts on the VCO to make the two 25 KHz signals the same phase. When this condition is met, the PLL circuit is locked. If the two signals have a large phase difference, the PLL is unlocked. In this condition, the unlocked signal is fed to CPU IC201 from lC3 and the transmitter is compelled to stop.

The VCO output from Q4 is fed to the TX amplifier Q2 and the first RX mixer

Ql9

buffer amplifier Q3.

4.3.2 Transmitter Circuit

A signal from the microphone is fed to a pre-emphasis operations amplifier IC3, and modulates VCO(Q4) through active LPF IC2.

The VCO output signal from Q4 is sent to the RF power amplifiers ICI, Ql and Q2 through buffer amplifier Q3. The RF signal from ICI is fed to the antenna through a low pass titter.

The DC voltage correlative to the RF output is detected by 02 and Q9. amplified by Q24 and

fed to ICI .The output voltage from ICI controls the RF power to keep the RF output at a con

stant level.

The VCO

IC201.

through

4.3.3 Receiver Circuit

1) RF Circiut The signal from the antenna passes through the single tuned band pass filter, and is amplified by RF amplifier Q17, and is fed into a triple tuned band pass filter. The signal is then mixed by (first mixer) and produces the first IF signal of 21.6 MHz. This signal is sent to a crystal filter (21.6 MHz) and first IF amplifier Q20, mixed by IC4 , the second mixer, and becomes an

audio signal after detection.

2) IF Circuit The output of the first IF amplifer Q20 is fed into IC4. IC4 contains the second mixer, second

local oscillator, 455KHz amplifer, quadrature detector and DC switching amplifer.

A455 KHz ceramic filter is installed between pins 3 and 5 of IC4 to examine the selectivity of this unit.

The detector output is separated into audio and noise components by an RC filter. The noise component is fed back to the noise amplifer section of 164. Its output is rectified by a diode in IC4 and then fed to the switching amplifer in IC4.

3) AF Circuit The AF signal from IC4 is amplified by IC5 to drive the speaker while the receiver is in the

squelched condition. Muting control of IC5 is carried out by the CPU IC 201.

4) Weather Alert Tone Detecting Circuit If a weather alert tone is included in the AF signal from IC4 while receiving the weather service broadcast, IC6 detects it and notifies an alert condition to CPU

Q19

IC201.

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 REVISED EDITION February 1991 and FCC Fact Sheet PR-5000 March 1990.

REMEMBER:

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

Use VHF Channel 70 only for Digital Selective Calling (DSC). It may be used for general-purpose calling using DSC. Your cooperation in not using Channel 70 for general intership com-

munications 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 messages, and never use profanity on the air.

OTHER REMINDERS:

Do not install or operate your radio until it is licensed. You can obtain a station license and call sign by completing FCC Form 506 and mailing it with the required fee to the FCC, Marine Ship Service, PO. Box 358275, Pittsburgh, PA 15251-5275. Form 506-A provides you with immediate operating authority, valid for 90 days after you mail your license application.

You need a radio operator license to operate a VHF Marine Radio only if you plan to dock in a foreign port or leave a foreign port to dock in a U.S. port.

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

tion 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 Requirements for Hand Held Portable VHF Marine Transceivers

10 Watts Power or Less

All transceivers, hand helds included, operated in the Maritime Radio Services are required to be operated under an appropriate maritime station license.

Operation of hand held VHF Marine trans-

ceivers without proper station license can lead to fines and/or administrative sanctions issued against its user and/or owner.

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

Associated Ship Unit: A hand held VHF Marine transceiver can be operated under an exist-

ing valid ship station license under the following conditions only:

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.

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:

The station will be operated aboard a vessel.

ii)

A station license for portable equipment is necessary to eliminate separate applications to operate a ship station aboard different vessels.

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 autho-

rized:

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.

Calling

Channel 16 & Working Channel

If-you wish to establish communications with another station

And-you know which working channel the station is monitoring

Then-initiate the call directly on that working channel

If-you wish to establish communications with another station

And-you do not know what working channel the station may be monitoring

Theninitiate the call on channel 16. After contact is made switch to a working channel.

NOTE: Due to congestion on channel 16 caused by frequent hailing of other vessels,

the FCC has approved channel 9 as a second

hailing channel.

Caution Every ship at sea is obliged to give absolute prior-

ity to radio communications relating to ships in distress-it is vital that false distress calls or messages not be broadcast.

Avoid excessive calling and radio checks

Always monitor before transmitting

Never interrupt emergency communications
