2.0 INTRODUCTION
This section explains the basic operating procedures for the TR-127GK or TR-127DX mobile CB radio.
2.1 CONTROLS AND CONNECTIONS
2.1.1 FRONT PANEL
Refer to the above Figure 2-1 for the location of the following controls.
1. MICROPHONE JACK: Used to connect microphone for voice source.
2. MIC GAIN CONTROL: Adjust the microphone gain in the transmit and PA modes. This controls
the gain to the extent that full talk power is available several inches away from the microphone. In
the Public Address (PA) mode, the control function as the volume control.
3. 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.
4. SQUELCH CONTROL: This knob is used to eliminate background noise being heard through the
receiver, which can be disturbing when no transmissions are being heard through the receiver. To
use this feature, turn the knob 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 signals will be heard at a maximum
clockwise setting.
5. RF GAIN CONTROL: This control is used to reduce the gain of the RF (receive) amplifier under
strong signal conditions.
6. SWR CAL CONTROL: This SWR CAL control allows the user to calibrate the SWR meter.
7. CLARIFY CONTROL: Allows tuning of the receive frequency above or below the channel
frequency.
8. CHANNEL SELECTOR: This control is used to select the desired transmit and receive channel.
9. FRONT PANEL METER: The front panel meter allows the user to monitor incoming signal
strength, RF output power and SWR level.
10. S-RF/CAL/SWR SWITCH: In the S-RF position, the meter will indicate the strength of the signal
being received, as well as the relative RF output of transmission. When calibrating the SWR meter,
you need to put this switch in the CAL position. To use the meter to measure the standing wave
ratio, turn the switch to the SWR position.
11. ANL/OFF SWITCH: In the ANL position, the Automatic Noise Limiter (ANL) in the audio
circuits is activated.
12. NB/OFF SWITCH: In the NB position, the Noise Blanker (NB) is activated. The NB is very
effective in eliminating repetitive impulse noise such as ignition interference.
13. PA/CB SWITCH: Select the mode of operation. In the PA position, the radio acts as public address
amplifier. Your voice will come out of the speaker that is plugged into the PA. SP. jack on the rear
panel. The radio does not operate when you are in the PA mode. In the CB position, the PA function
is disabled and the radio will transmit and receive on the speaker that is connected.
14. TONE SWITCH HI/LO: This switch changes tone quality in receive only. In LO position, bass is
increased and in HI position, treble is increased.
15. CH19/NORMAL SWITCH: Channel 19 switch is used for instant to information channel 19.
16. 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.
17. ANT LED: This LED lights red when your SWR is higher than about 3:1. This is not an exact
indicator of 3:1 SWR, but it is an indication that you should check your SWR reading.
18. CHANNEL DISPLAY: The channel display indicates the current selected channel.

2.2 MICROPHONE
The push-to-talk switch on the microphone controls the receiver and transmitter. Press the switch and
the transmitter is activated, release switch to receive. When transmitting, hold the microphone two
inches from your mouth and speak clearly in a normal voice. This transceiver comes complete with a
low impedance dynamic microphone.
2.3 OPERATION
2.3.1 PROCEDURE TO RECEIVE
1. Be sure that the 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 to a comfortable listening level.
4. Set the MODE switch to the desired mode.
5. Listen to the background noise from the speaker. Turn the SQUELCH knob slowly clockwise until
the noise just disappears. The SQUELCH 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 CLARIFY control to optimize AM signals.
2.3.2 PROCEDURE TO TRANSMIT
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.

2.4 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 a low output impedance characteristic. 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 the fourth is for receiving control.
The microphone should provide the functions shown in the schematic below (Figure 2-3).

CHAPTER 3
CIRCUIT
TR-127GK/DX
DESCRIPTION
3.0 INTRODUCTION
This section explains the technical theory of operation for the TR-127GK or TR-127DX mobile CB
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, and Q23. The
PLL circuit is programmed by the rotary channel switch GPS-668. The GPS-668 communicates the
correct binary data information to the programmable divider inside of IC2. IC2 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, Q12. The
RF signal is fed into the mixer circuit of Q13 and then into the AM IF section of the receiver. The
signal is then detected by the AM detector and then fed to the audio amplifier 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) The AF power amplifier modulates the last RF amplifier, which produces a true amplitude
modulated RF signal.
3.4 TRANSMITTER AMPLIFIER CIRCUIT
The transmitter takes the basic exciter signal from IC4 of the TX mixer and amplifies it through a series
of amplifiers consisting of Q18, Q17 and Q16 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 (option) If cracked or broken, replace it.
Coaxial cable
If sheath is cracked or immersed
in water, install new coaxial
cable.
Coaxial & power plug If loosened, reconnect. If
connections
Battery connection
corroded, clean contacts.
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.
