1.10 Transmitting

After selecting class of emission and frequency, you can transmit by pressing the PTT (press-

to-talk) switch on the microphone (handset). (“T” appears when the PTT switch is pressed.

Output power can be evaluated on the operation display. Do not transmit any signal other than

emergency during the silence period, 00 to 03 min, and 30 to 33 min of every hour.

Tuning the antenna

Maximum transmission power is achieved only when the antenna impedance and transmitter

impedance match each other. Because the antenna impedance changes with frequency a means

must be provided to match (tune) the antenna impedance with the transmitter impedance. This

is done with the antenna coupler. The antenna coupler automatically tunes the transmitter to a

wide range of different antenna length (6 – 15 m). To initiate the automatic tuning, do the

following:

1. Press the PTT switch on the microphone (handset), or the [TUNE/7] key.

2. “TUNE” appears on the display.

3. Tuning will be completed within 2 to 15 seconds for a newly selected frequency, or less than

0.5 seconds for a once tuned frequency. (A built-in memory remembers coil and capacitor

settings.)

4. When the tuning process is successfully completed “OK” appears.

Using the microphone

Hold the microphone close to your mouth, press the PTT switch and speak clearly.

Monitoring transceiver output power

The meter shows TX filter output level.

Figure 1-9 Meter

Reducing transmitter power

To conserve energy and to minimize possible interference to other stations, reduce the transmis-

sion power. This should be done when using the transceiver in a harbor, near the shore or close to

communication partner (other ship). Each pressing of the [H/L /8] key selects high or low

output power. “LOW” appears on the display when low output power is selected. The output

power on 2182 kHz (distress and calling) is the rated maximum regardless of the position of the

[H/L /8] key.

1.11 Distress Call on 2182 kHz

The frequency 2182 kHz is an International radiotelephony distress, urgency and safety fre-

quency for ship stations, public and private coast stations, and survival craft stations. It is also

used for call and reply by ship stations on a primary basis and by public coast stations on a

secondary basis.

Distress or emergency call is generally initiated by a radiotelephone alarm signal on 2182 kHz.

Watch keeping receivers on other parties will hear your call.

1. Press the [2182] key. 2182 kHz and the class of emission H3E is automatically selected (J3E

may be selected depending on system setting).

When the [2182] key is pressed, the following parameters are set automatically:

AGC: ON

Output power: Maximum

Loudspeaker: ON

Squelch: OFF

1-12

2. While pressing and holding down the [ALM] key, press

the [ENT] key. The alarm signal, modulated at 1300 Hz

and 2200 Hz tones alternately, is emitted at full power

for 45 sec.

The alarm can be monitored from the loudspeaker. The

alarm may be canceled at any time by pressing the [ENT]

key for immediate speech transmission.

3. Distress calls and Distress message

(1) Speak slowly and distinctly, “MAYDAY, MAY-

DAY, MAYDAY, pronounced as the French expres-

sion “m’aider”.

(2) This is;

(3) The name of your vessel and call sign three times.

Then, continue with the distress message, which con-

sists of:

(1) The distress signal MAYDAY;

(2) The name of the mobile station in distress;

(3) Particulars of its position (in latitude and longitude)

(4) The nature of the distress;

(5) The kind of assistance desired;

(6) Any other information which might facilitate rescue, for length, color, and type of

vessels, number of persons on board.

4. Indicate the end of message by saying “Over.”

5. When you receive no answer to a distress message, repeat at intervals over again the radio-

telephone alarm signal, the distress call and the distress message.

Distress frequencies

All distress frequencies including 2182 kHz are shown below:

1.12 Receiving

You can select a receiving frequency by one of the following methods:

- Direct frequency entry, or

- Channel number entry

Adjusting RF gain

In normal use the [RF GAIN] control should be set for maximum. If the audio on the received

channel is unclear or interfered with other signals, adjust (usually reduce) the control to im-

prove clarity.

Clarifier adjustment

If reception is unclear, try to clarify the signal as follows. For manual entry of frequency, sim-

ply turn the [FREQ/CH] control for fine tuning.

1. Press the [CLARI/3] key. (If a frequency is selected by CH No., the cursor which was

located at the channel number, moves under the 10 Hz place and “CLAR” appears on the

display.)

2. Turn the [FREQ/CH] control to fine tune the receiver on the wanted frequency.

3. To terminate this operation, press the [CLARI/3] key again. The cursor returns to the chan-

nel number.

S-meter

During reception, the meter works as a Sensitivity Meter indicating the relative signal strength

coming into the receiver front end. While in transmission, it indicates output level at the trans-

ceiver.

0246810S

Figure 1-11 S-meter

Note: S-meter will not work with AGC off.

Monitoring traffic on intended transmit frequency

When a semi-duplex (two-frequency simplex) channel is selected, it is recommended to moni-

tor it if there is no existing traffic on the frequency you are going to use. To do this, press the

[RX] key followed by the [ENT] key. The transceiver unit monitors traffic on the selected

frequency for three sec. If you want to monitor continuously, press the [TX] key followed by

the [ENT] key.

1-14

Receiving AM broadcasting stations

1. Press the [MODE/1] key repeatedly to select H3E.

2. To tune in a 15,260 kHz shortwave station, for instance, press as below:

[RX], [1], [5], [2], [6], [0], [0], [ENT]. Be sure to enter the last zero.

Squelch control

Squelch is used to mute the receiver audio output when the receiver input is less than a preset

value or dominant noise is higher than a preset (1000 Hz) frequency. To switch the squelch

function ON, press the [SQL/5] key. Make sure the label “SQ” appears on the display. To pick

up a weak signal at high audio frequencies, you should remove the squelch function notwith-

standing a possible increase of background noise. To do this, press the [SQL/5] key again.

Make sure the label “SQ” goes off.

Noise blanker (NB)

The noise blanker clips inputs of noise resulting from an engine ignition or motor brush sparks.

It can be enabled or disabled through the system settings.

1.13 Frequency Scan

Channel scan

Scan is the function where the receiver watches 10/group user or ITU channels in succession at

predetermined intervals. The scan-stop signal level and scan-stop time can be changed on sys-

tem codes 9951 and 9952, respectively. AGC is automatically turned on when scanning is acti-

vated.

1. Recall user or ITU channel.

User channels

User channels are divided into 20 groups in the scan mode as below.

ITU channels

To select the scan group (band or channel, including user channels), shift the cursor to either the

position of the band or channel number by pressing the [CURS/2] key. (Band scan is useful to

watch frequencies on the same channel in different bands.)

2. Press the [SCAN/6] key, and “SCAN” appears. The receiver starts scanning, stopping at a

channel where the signal is stronger than the scan-stop level. The receiver will restart scan-

ning when the traffic goes out of that channel or designated time elapses, depending on

system setting 9952.

For example, the scan group is “channel” and scan starts at ITU 1203, as shown in Figure 1-

12.

1.14 Frequency Sweep

Sweep is the function where the receiver searches for a signal within a selected frequency

coverage. AGC is automatically turned on in frequency sweep.

The defaults of respective parameters are as follows:

Sweep stop signal level: 3

Sweep stop time: 2 sec

Sweep width: 100 kHz

Step frequency: 1 kHz

These can be adjusted on system codes 9951 through 9954.

Note: Sweep width is the frequency width to sweep on both sides of the selected frequency.

Sweep step is the frequency interval at which the receiver sweeps the sweep width.

Procedure

1. Select the sweep center by key operation.

2. Press the [SCAN/6] key. “SWEEP” appears and the receiver starts sweeping. To stop sweep-

ing, press the [SCAN/6] key.

2.2 Remote Station RB-500 (requires optional Remote-B

Board)

Priority

The Remote Station RB-500 usually has higher priority than the FS-1503. This means that opera-

tion of the FS-1503 is disabled when the handset of the RB-500 is picked up. The indication

“REM” appears on the FS-1503 display when the remote station is in operation and the PTT

switch on the microphone of the FS-1503 is inoperative.

Communication on 2182 kHz

When 2182 kHz is selected on the FS-1503, the FS-1503 takes priority.

2.3 Intercom

9951 Scan/sweep-stop signal level

When the receiver detects a signal whose level is stronger than the preset

level it stops scanning and receives the signal. The setting on system code

9955 is available only when “0” (SQ working condition) is selected here.

Setting range: 0 (Squelch working condition is effective as set on code

9955), 1-10 (S-meter level); Factory setting: 3

9952 Scan/sweep-stop time

When a signal is detected, the receiver stops scanning/sweeping and dwells

on this channel frequency. When “0” (RX) is selected, the receiver keeps

receiving until the traffic goes out of this channel frequency. Define the

dwell time between 1 and 99 sec.

Setting range: 0 (RX), 1-99 sec; Factory setting: 2

9953 Sweep width setting range: 0.01-30000.00 kHz; Factory setting: 100.0

9954 Sweep step frequency

Setting range: 0.01-30000.00 kHz; Factory setting: 1.00

9955 Squelch activation

“Squelch activation” is the method by which the squelch is activated.

Setting range: 0, 1, 2, 3; Factory setting: 3

0: Voice

The squelch is opened by signal frequency less than 1000 Hz (factory set-

ting). This frequency can be changed between 500 – 2000 Hz on system

code 9958. The loudspeaker reproduces a sound when the signal is lower

than the preset frequency.

Squelch OPEN:

Audio signal is detected and a sound is reproduced through the loudspeaker.

Squelch CLOSED:

No input signal but only noise is coming into the receiver. The receiver is

muted.

1: Level

The squelch is activated depending on “signal strength”. The factory setting

is “5”. You can change the level between 0 - 10 on system code 9956.

2: And

The squelch opens when both “voice” and “signal strength” meet the set-

ting.

3: Or

The squelch opens by either “voice” or “signal strength”, whichever meets

the setting.

9956 Squelch level. Setting range: 0-10; Factory setting: 5
