1. ON/OFF VOLUME CONTROL : This knob controls the volume and power to the radio. To turn
radio on, rotate the knob clockwise. Turning the knob further will increase the volume of the
receiver.

2. SQUELCH CONTROL : This switch is used to eliminate background noise being heard through
the receiver which can be disturbing when no transmission are being heard through the received.
To use this feature, turn the switch fully counterclockwise and then turn clockwise slowly until the
background noise is just eliminated. Further clockwise rotation will increase the threshold level
which a signal must overcome in order to be heard. Only strong signal will be heard at a maximum
clockwise setting.

3. MIC GAIN CONTROL : Adjust the microphone gain in the transmit modes. This controls the
gain to the extent that full talk power is available several inches away from the microphone.

4. RF GAIN CONTROL : This control is used to reduce the gain of the RF amplifier under strong
signal conditions.

5. E-TONE CONTROL : This control is used to control the echo effects.

6. BAND SELECTOR : This band selector allow the user to select the desired band.

3
7. MODE CONTROL : This control allows you to select one of the following operating modes :
CW/FM/AM/USB/LSB.

8. FINE/COARSE CONTROL : Allows variation of the receive operating frequency above or

below the assigned frequency. Although this control is intended primarily to tune in SSB/CW
signals, it may be used to optimize AM/FM signals as described in the Operating Procedure
paragraphs. Coarse operates both TX/RX but Fine only in RX.

9. CHANNEL SELECTOR : This control is used to select a desired transmit and receive channel.

10. FRONT PANEL METER : The Front Panel Meter allows the user to monitor signal strength, RF
output power and SWR level.

11. TX/RX LED : The red LED indicates the unit is in the transmit mode. The green LED indicates
the unit is in the receive mode.

12. FREQUENCY COUNTER : This frequency counter indicates the selected channel frequency
digitally.

13. TALKBACK SWITCH : This switch is used to monitor the sound feedback effects.

14. HI/LOW SWITCH : This switch select HI or LOW band of operation.

15. S-RF/SWR/ SWITCH : In the S-RF position, the meter swings proportionally to the strength of
the received signal. When transmitting, the meter indicates relative RF output power. When in the
SWR position, the standing wave ratio is measured.

16. NB/ANL/OFF SWITCH : When the switch is place in the NB/ANL position, the RF Noise
Blanker (NB) and the Automatic Noise Limiter (ANL) in the audio circuits are activated. The
Noise Blanker is very effective in eliminating repetitive impulse noise such as ignition interference.

17. ROGER BEEP : When this switch is placed in the ROGER BEEP position, the radio automatically
transmits an audio tone at the end of your transmission. This indicates the end of your transmission so
that people who are having trouble hearing you will know that you are done speaking. As a courtesy to
others, use the Roger Beep only when necessary.

18. +10KHz SWITCH : In the +10KHz position, the transmit and receive frequency is shifted 10 KHz
up.

19. CHANNEL DISPLAY : The channel display indicates the current selected channel.

PROCEDURE TO RECEIVE AND TRANSMIT

A. MICROPHONE
The receiver and transmitter are controlled by the push-to-talk switch on the microphone. Press the
switch and the transmitter is activated, release switch to receive. When transmitting, hold the
microphone two inches from the mouth and speak clearly in a normal voice. This transceiver comes
complete with a low impedance dynamic microphone.

B. PROCEDURE TO RECEIVE
1. Be sure that power source, microphone and antenna are connected to the proper connectors before
going to the next step.

2. Turn VOL knob clockwise to apply power to the radio.

3. Set the VOL for a comfortable listening level.

4. Set the MODE switch to the desired mode.

5. Listen to the background noise from the speaker. Turn the SQ knob slowly clockwise until the
noise just disappears. The SQ is now properly adjusted. The receiver will remain quiet until a
signal is actually received. Do not advance the control too far or some of weaker signals will not be
heard.

6. Set the CHANNEL selector switch to the desired channel.

7. Set the RF GAIN control fully clockwise for maximum RF gain.

8. Adjust the FINE/COARSE control to clarify the SSB/CW signals or to optimize AM/FM signals.

C. PROCEDURE TO TANSMIT
1. Select the desired channel of transmission

2. Set the MIC GAIN control fully clockwise.

3. If the channel is clear, depress the push-to-talk switch on the microphone and speak in a normal
voice.

RECEIVING SSB SIGNALS

There are four types of signals presently used for communications in the Citizens Band : FM, AM, USB and LSB. When
the MODE switch on your unit is placed in the AM position, only standard double-side band and in FM position, only
frequency deviation, full carrier signals will be detected. An SSB signal may be recognized while in the AM or FM mode
by its characteristic "Donald Duck" sound and the inability of the detector to produce an intelligible output. The USB and
LSB modes will detect upper side band and lower side band respectively, and standard AM signals.

SSB reception differs from standard AM reception in that an SSB receiver does not require a carrier or opposite side band
to produce an intelligible signal. A single-side band transmitted signal consists only of the upper or the lower side band and
no carrier is transmitted. The elimination of the carrier from the AM signal helps to eliminate the biggest cause of whistles
and tones heard on channels which make even moderately strong AM signals unreadable. Also, SSB takes only half the
space of an AM channel, therefore two SSB conversations will fit into each channel, expanding the 40 AM channels to 80
SSB channels. The reduction in channel space required also helps in the receiver because only half of the noise and
interference can be received with 100% of the SSB signal.

An SSB signal may be received only when the listening receiver is functioning in the same mode.
In other words, an upper side band signal (USB) may be made intelligible only if the receiver is
functioning in the USB position.

If a lower side band (LSB) signal is heard when the receiver is in the USB mode, no amount of tuning will make the signal
intelligible. The reason for this may be understood if you consider that when the modulation is applied to the transmitter's
microphone in the USB mode, the transmitter output frequency is increased whereas in the LSB mode the transmitter's
output frequency is decreased.

The result in listening to the receiver is that when the MODE switch is in the proper position (either USB or LSB), a true
reproduction of a single tone of modulation will result, and if the tone is increased in frequency (such as a low-pitched
whistle or a high-pitched whistle) you will hear the increase in the output tone of the receiver. If the incorrect mode is
selected, an increase in tone of a whistle applied to the transmitter will cause a decrease in the resultant tone from the
receiver.

Thus when a voice is used in place of a whistle or tone, in the proper listening mode the voice will
be received correctly whereas in the incorrect mode, the voice will be translated backwards and
cannot be made intelligible by the FINE/COARSE control.

When listening to an AM transmission, a correct side band is heard in either mode since both upper and lower side bands
are received.

7
Once the desired SSB mode has been selected, frequency adjustment may be necessary in order to make the incoming
signal intelligible. The FINE/COARSE control allows the operator to vary frequency above or below the exact frequency
of the channel. If the sound of the incoming signal is high or low pitched, adjust the operation of the FINE/COARSE.

Consider it as performing the same function as a phonograph speed control. When the speed is set
too high, voices will be high-pitched and if set too low, voice will be low-pitched. Also, there is
only one correct speed that will make a particular record produce the same sound that was recorded.
If the record is played on a turntable that is rotated in the wrong direction (opposite side band) no
amount of speed control (FINE/COARSE) will produce an intelligible sound.

An AM signal received while listening in one of the SSB modes will produce a steady tone (carrier) in addition to the
intelligence, unless the SSB receiver is tuned to exactly the same frequency by the FINE/COARSE control. For simplicity,
it is recommended that the AM modes be used to listen to AM signals.

 ALTERNATE MICROPHONES AND INSTALLATION

For best results, the user should select a low-impedance dynamic type microphone or a transistorized microphone.
Transistorized type microphones have low output impedance characteristics. The microphones must be provided with a
four-lead cable. The audio conductor and its shielded lead comprise two of the leads. The third lead is for transmit control
and fourth is for receiving control.

The microphone should provide the functions shown in schematic below.

4 WIRE MIC CABLE

Pin Number Mic Cable Lead

1 Audio Shield
2 Audio Lead
3 Transmit Control
4 Receive Control

Fig. 1 Your transceiver microphone schematic.

If the microphone to be used is provided with precut leads, they must be revised as follows.

1. Cut leads so that they extend 7/16" beyond the plastic insulating jacket of the microphone cable.

2. All leads should be cut to the same length. Strip the ends of each wire 1/8" and tin the exposed
wire.

Before beginning the actual wiring, read carefully the circuit and wiring information provided
with the microphone you select. Use the minimum heat required in soldering

9
 the connections. Keep the exposed wire lengths to a minimum to avoid shorting when the microphone
plug is reassembled.

Fig. 2 Microphone plug wiring

To wire the microphone cable to the plug provided, proceed as follows :

1. Remove the retaining screw.

2. Unscrew the housing from the pin receptacle body.

3. Loosen the two cable clamp retainer screws.

4. Feed the microphone cable through the housing, knurled ring and washer as shown Figure 2.

The wires must now be soldered to the pins as indicated in the above wiring tables. If a vise or
clamping tool is available it should be used to hold the pin receptacle body during the soldering
operation, so that both hands are free to perform the soldering. If a vise or clamping tool is not
available, the pin receptacle body can be held in a stationary position by inserting it into the
microphone jack on the front panel. The numbers of the microphone plug are shown in Fig. 3, as
viewed from

5. the back of the plug. Before soldering the wire to the pins, pre-tin the wire receptacle of each pin of
the plug.
10
 Fig. 3 Microphone plug pin numbers viewed from rear of pin receptacle.

6. Be sure that the housing and the knurled ring of Figure 2 are pushed back onto the microphone
cable before starting to solder. If the washer is not captive to the pin receptacle body, make sure
that it is placed on the threaded portion of the pin receptacle body before soldering.

7. If the microphone jack is used to hold the pin receptacle during soldering operation, best results are
obtained when the connections to pin 1 and 3 are made first and then the connections to pins 2 and
4. Use a minimum amount of soldering and be careful to prevent excessive solder accumulation on
pins, which could cause a short between the pin and the microphone plug housing.

8. When all soldering connections to the pins of the microphone are completed, push the knurled ring
and the housing forward and screw the housing onto the threaded portion of the pin receptacle
body. Note the location of the screw clearance hole in the plug housing with respect to the threaded
hole in the pin receptacle body. When the housing is completely threaded into the pin receptacle
body, a final fraction of a turn either clockwise or counterclockwise may be required to align the
screw hole with the threaded hole in the pin receptacle body. When these are aligned, the retaining
screw is then screwed into place to secure the housing to the pin receptacle body.
9. The two cable clamp retainer screws should now be tightened to secure the housing to the
microphone cord. If the cutting directions have been carefully followed, the cable clamp should
secure to the insulation jacket of the microphone cable.

10. Upon completion of the microphone plug wiring, connect and secure the microphone plug in the
transceiver.

 CHAPTER 3 CIRCUIT DESCRIPTION

3.0 INTRODUCTION
This section explains the technical theory of operation for the SS－158 EDX mobile
AMATEUR radio.

3.1 PLL CIRCUIT

The Phase Lock Loop (PLL) circuit is responsible for developing the receiver’s first
local oscillator signal and the transmitter’s exciter signal. The PLL circuit consists
primarily of IC2, IC3, IC4, IC5, Q25, Q27, Q28 and Q29. The PLL circuit is
programmed by the rotary channel switch GPS-501. The GPS-501 & Band switch
communicates the correct binary data information to the into IC4&IC5. Sum binary
code inside IC3 then controls the VCO (Voltage Controlled Oscillator) to oscillate on
the correct frequency. This signal is fed either into the receiver’s first mixer (for
receive operation) or the transmitter’s mixer (for transmit operation).

3.2 RECEIVER CIRCUIT

The incoming RF signal comes into the radio via the antenna and into the front-end
pre-amp, Q17. The RF signal is fed into the mixer circuit of Q18/Q19 and then into
the AM/FM/SSB IF section of the receiver. AM/FM IF signal is into FL2 by
Q10,Q11,Q12 AMP,AM signal then detected by the AM detector(D30,D31) and then
fed to the audio amplifier(IC8) section of the receiver and finally out to the
speaker.FM signal then detected by the FM detector(Q12,L4) fed to the audio
amplifier(IC8) section of the receiver and finally out to the speaker.SSB IF signal is
into FL3 by Q20, Q21, Q22, Q23 AMP,SSB signal then mix with be from X4’
frequency and then fed to the audio amplifier(IC8) section of the receiver and finally
out to the speaker.

3.3 TRANSMITTER MODULATION CIRCUIT

(1) The transmitter modulation circuit modulates the low-level RF signal from the
PLL exciter circuit with the user’s audio voice signal from the microphone. The
audio from the microphone is then amplified and fed into the transmit amplifier
circuit.

(2) If the transceiver is in the AM mode, the AF power amplifier modulates the last
RF amplifier, which produces a true amplitude modulated RF signal.

(3) If the transceiver is in the SSB mode, the audio signal is mixed with the
10.6975MHz oscillator in IC6.

(4) If the transceiver is in the FM mode, the audio signal is mixed with the
oscillator in IC2.
12
3.4 TRANSMITTER AMPLIFIER CIRCUIT
The transmitter takes the basic exciter signal from IC9 of the TX mixer and amplifies
it through a series of amplifiers consisting of Q52, Q51, Q49 ,Q47and Q48 where it is
sent out to the antenna connector.

MAINTENANCE

5.0 PRECAUTIONS
The inherent quality of the solid-state components used in this transceiver will
provide many years of continuous use. Taking the following precautions will prevent
damage to the transceiver.

(i) Never key the transmitter unless an antenna or suitable dummy load is connected
to the antenna receptacle.

(ii) Ensure that the input voltage does not exceed 16 VDC or fall below 11.

(iii) Transmitting over long periods can cause heat built-up and cause transmitter
damage.

5.1 PERIODIC INSPECTION

This unit is aligned at the factory to deliver maximum performance. However,
continued performance cannot be expected without periodic inspection and
maintenance. Important points to be checked regularly are as follows;

Check Item Action

Whip antenna If cracked or broken, replace it.
(option)
Coaxial cable If sheath is cracked or immersed
in water, install new coaxial
cable.
Coaxial & power If loosened, reconnect. If
plug connections corroded, clean contacts.
Battery connection If corroded, clean power
terminals.
Ground terminal If corroded, clean terminal.

5.2 FUSE REPLACEMENT

To protect the equipment from serious damage, a fuse is provided on the power
supply lines. The fuse protects against over voltage / reverse polarity or internal fault
of the equipment. If the fuse has blown, first find out the cause of the trouble before
replacing it. A fuse rated for more than the transceiver requirement should not be
used, since it may permanently damage the equipment. Damage due to over fusing is
not covered by the warranty.
