Receiver System

The receiver is double conversion superheterodyne. The
frequency configuration is shown in Figure 1.
Front-end RF Amplifier
An incoming signal from the antenna is applied to an RF amplifier (Q353) after passing through a transmit/receive switch circuit (D603, D605 are off) and a band pass filter (L357, L356 and varactor diodes : D353, D354). After the signal is amplified (Q353), the signal is filtered through a band pass filter (L354, L355 and varactor diodes: D351, D352) to eliminate unwanted signals before it is passed to the first mixer.
The voltage of these diodes are controlled by tracking the CPU (IC101) center frequency of the band pass filter. (See Fig. 2.)
First Mixer
The signal from the RF amplifier is heterodyned with the first local oscillator signal from the PLL frequency synthesizer circuit at the first mixer (Q352) to create a 49.95MHz first intermediate frequency (1st IF) signal. The first IF signal is then fed through one pair of monolithic crystal filter (MCF : XF351) to further remove spurious signals.
IF Amplifier
The first IF signal is amplified by Q351, and then goes to IC301 (FM processing IC). The signal is heterodyned again with a second local oscillator signal within IC301 to create a 450kHz second IF signal. The second IF signal is then fed through a 450kHz ceramic filter (Wide : CF301, Narrow : CF302) to further eliminate unwanted signals before it is am­plified and FM detected in IC301.

Wide/Narrow Switching Circuit
The Wide port (pin 65) and Narrow port (pin 64) of the CPU is used to switch between ceramic filters. When the Wide port is high, the ceramic filter SW diodes (D303, D302) cause CF301 to turn on to receive a Wide signal.
When the Narrow port is high, the ceramic filter SW di­odes (D303, D302) cause CF302 to turn on to receive a Nar­row signal. (See Fig. 3.)

AF Signal System
The detection signal from IF IC (IC301) goes to D/A con­verter (IC161) to adjust the gain and is output to AF filter (IC251) for characterizing the signal. The AF signal output from IC251 and the DTMF signal, BEEP signal are summed and the resulting signal goes to the D/A converter (IC161). The AFO output level is adjusted by the D/A converter. The signal output from the D/A converter is input to the audio power amplifier (IC252). The AF signal from IC252 switches between the internal speaker and speaker jack (J1) output. (See Fig. 4.)

Squelch Circuit
The detection output from the FM IF IC (IC301) passes through a noise amplifier (Q301) to detect noise. A voltage is applied to the CPU (IC101). The CPU controls squelch ac­cording to the voltage (SQIN) level. The signal from the RSSI pin of IC301 is used for S-meter. The electric field strength of the receive signal can be known before the SQIN voltage is input to the CPU, and the scan stop speed is improved.
Fig. 5 Squelch circuit

PLL Frequency Synthesizer

The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission.
PLL
The frequency step of the PLL circuit is 5 or 6.25kHz. A
16.8MHz reference oscillator signal is divided at IC401 by a fixed counter to produce the 5 or 6.25kHz reference fre­quency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q410, then divided in IC401 by a dual­module programmable counter. The divided signal is com­pared in phase with the 5 or 6.25kHz reference signal in the phase comparator in IC401. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 6.)
VCO
The operating frequency is generated by Q406 in transmit mode and Q405 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D405 and D406 in transmit mode and D403 and D404 in receive mode). The TX/RX pin is set high in receive mode causing Q408 and Q407 to turn Q406 off, and turn Q405 on. The TX/RX pin is set low in transmit mode. The outputs from Q405 and Q406 are amplified by Q410 and sent to the RF amplifiers. (See Fig.
6.)

CIRCUIT DESCRIPTION
Unlock Circuit
During reception, the 8RC signal goes high, the 8TC signal goes low, and Q34 turns on. Q33 turns on and a voltage is applied to 8R. During transmission, the 8RC signal goes low, the 8TC signal goes high and Q36 turns on. Q35 turns on and a voltage is applied to 8T.
The CPU monitors the PLL (IC401) LD signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this signal and makes the 8TC signal low. When the 8TC signal goes low, no voltage is applied to 8T, and no signal is transmitted. (See Fig. 7.)

Transmitter System

Outline
The transmitter circuit produces and amplifies the desired frequency directly. It FM-modulates the carrier signal by means of a varicap diode.
Power Amplifier Circuit
The transmit output signal from the VCO passes through the transmission/reception selection diode (D409) and ampli­fied by Q501, Q502 and Q503. The amplified signal goes to the final amplifier (Q504) through a low-pass filter. The low­pass filter removes unwanted high-frequency harmonic com­ponents, and the resulting signal is transmitted through the antenna terminal. (See Fig. 8.)
APC Circuit
The automatic transmission power control (APC) circuit detects part of a final amplifier output with a diode (D606, D607) and applies a voltage to IC501. IC501 compares the APC control voltage (PC) generated by the D/A converter (IC161) and DC amplifier (IC203) with the detection output voltage. IC501 generates the voltage to control Q503 and Q504 and stabilizes transmission output.
The APC circuit is configured to protect over current of Q503 and Q504 due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage and tem­perature variations. (See Fig. 9.)

The DCS and CTCSS signals are output from QT/DQT of the CPU (IC101) and summed with the external pin DI line by the summing amplifier (IC203) and the resulting signal goes to the D/A converter (IC161). The DTMF signal is output from DTMF pin of the CPU and summed with a MIC signal by the summing amplifier (IC203), and the resulting signal goes to the D/A converter (IC161).
The D/A converter (IC161) adjusts the MOD level and the balance between the MOD and CTCSS/DCS levels. Part of a CTCSS/DCS signal is summed with MOD and the resulting signal goes to the VCOMOD pin of the VCO. This signal is applied to a varicap diode in the VCO for direct FM modula­tion.

D/A Converter
The D/A converter (IC161) is used to adjust MO modula­tion, AF volume, TV voltage, FC reference voltage, and PC POWER CONTROL voltage level.
Adjustment values are sent from the CPU as serial data. The D/A converter has a resolution of 256 and the following relationship is valid:
D/A output = (Vin – VDAref) / 256 x n + VDAref
Vin: Analog input
VDAref: D/A reference voltage
n: Serial data value from the microprocessor (CPU)

Power Supply Circuit

When the power switch on the display unit is pressed, the power port on the display unit which is connected port 17 (POWER), goes low, then port 82 (SBC) goes high, Q32 turns on, SB SW (Q31) turns on and power (SB) is supplied to the radio.
When the DC power supplied to the radio, the voltage regulator IC (IC33) supply into the CPU VDD and reset voltage detect IC (IC34). IC34 will generate signal (RESET) in to the reset terminal on the CPU (IC101) to carry out a power ON reset. If DC power is less than about 9.5V, the radio is unable to power on.
When the DC power voltage deceases from normal volt­age, the INT voltage detector IC (IC35) will set to high on CPU port 18 (INT) if B line will became less than about 9.5V. Then CPU send to EEPROM (IC66) the backup data and go into STOP mode.
This circuit has an overvoltage protection circuit. If a DC voltage of 18V or higher is applied to the base of Q61, this voltage turns Q61 on and will set to high on CPU port 18 (INT). Then CPU send to EEPROM (IC66) the backup data and go into stop mode. (See Fig. 16.)

Data Terminal and Peripheral Circuits

CN2 (data terminal) is the data communications terminal on the TX/RX PCB. It handles transmission control, data in­put/output, and squelch signals.
There are two data communications modes : 9600bps mode and 1200bps mode. Unlike with 1200bps AFSK, with this type of high-speed modulation, frequency modulation is carried out after the digital base band signals (rectangular wave) are passed through a band limiting filter. For 9600bps GMSK for example, compared to 4800Hz signals (nearly sine wave signals passed through a filter), these signals have a hissing sound like digital modulation when listened to by ear. Different types of modulation, such as GMSK is distin­guished by the type of band limiting filter.

CIRCUIT DESCRIPTION
TM-271A/271E
Transmission Signals
Transmission modulation signals enter from PKD of the data terminal (CN2). The path to the modulation depends on whether communications are 1200bps or 9600bps mode.
For 1200bps mode, the transmission modulation signals from single analog switch (IC204) pass through MIC amplifier (IC201,202) and summing amplifier (IC203), and go to VCO (X401) through D/A converter (IC161).
For 9600bps mode, the transmission modulation signals from single analog switch (IC205) pass through summing amplifier (IC303), go to TCXO (X401) and VCO through D/A converter (IC161). (See Fig. 17.)
Reception Signals
PR9 is the 9600bps data communications reception out­put. It outputs the FM detection circuit output through an AF filter (IC251). These signals are always output whether the squelch is open or closed.

Squelch Signal Output Circuit
The squelch circuits is input to the TNC to prevents con­flicts from occurring between simultaneous receive mode and transmit mode traffic during packet communications (only during 1200bps). The signal is output from pin 29 of IC101 to the data terminal. The logic is as shown in the table below.
