ReceivingⅡ
Chart II
(1) The front end of U Band (RFAmplifier)
The signal which is received from the antenna enters the transmission/receive change-over switch
diode circuit (D332, D333, D338 and D339), then goes through BPF(L1560, L561 and L562), and is
enlarged by RF amplifier (T539). The signal goes through the BPF (L544 and L545), and then enters
the mixing. These BPF is adjusted by the variable condenser(D531，D532，D533，D534 ). Input
voltage through the the variodencer is adjust to output voltage by the D/A switch (U723).(See Chart II)
(2)The front end of V Band(RF Amplifier)
The signal which is received from the antenna enters the transmission/receive change-over switch
diode circuit (D335，D336，D527 and D528), then goes through BPF(L568, L543 and L546), and is
enlarged by RF amplifier (T540).The signal goes through the BPF(L566), and then enters the mixing.
These BPF (D541, D542, D535 and D536)adjusted by the variable condenser. The input voltage by
variable condenser is adjusted by the outputting voltage by D/A switch (U723).( See Chart 2)
(3) The 1st Mixer
The signals from the front end of U Band and the Rx LO prouduced by PLL electro circuit creat the 1st
intermediate frequency signal of 38.850MHz on T537 Mixing. The 1st intermediate frequency signal
enters the crystal filter FL519 and FL50（UM5-3P 38.85M）to eliminate the signals from the adjacent
channels.
The signals from the front end of V Band and the Rx LO prouduced by PLL electro circuit creat the 1st
intermediate frequency signal of 29.250MHz on T323 Mixing. The 1st intermediate frequency signal
enters the crystal filter FL521 and FL522（UM5-3P 29.25M）to eliminate the signals from the adjacent
channels.(See Chart II)
www.wouxun.com

(4)Intermediate Frequency Enlarging Circuit
For U band, the 1st intermediate frequency signal via filter enters the 1st intermediate frequency
amplifier T527(2SC4215) to amplify and enter the intermediate frequency system IC U524. The
intermediate frequency system chip provides 2nd mixer, 2nd local oscillations’ signals, limiting
amplifier, orthogonal intersection detector and RSSI(Receiving Signal Strength Indicator). The 2nd
mixer mixes the 1st intermediate frequency signal and the 2nd local oscillations’ signals output, and
then creates the 2nd intermediate frequency signal 450KHz. The 2nd intermediate frequency signal
continuously eliminate the signals from the adjacent channels via ceramic filter(FL515). The 2nd
intermediate signal through filter is enlarged by limiting amplifier and demodulated by orthogonal
detector with chinaware discriminator (CR514). The demodulated signal enters the tone circuit.
For V band, the 1st intermediate frequency signal via filter enters the 1st intermediate frequency
amplifier T528 (2SC4215) to amplify and enter the intermediate frequency system IC U525. The
intermediate frequency system chip provides 2nd mixer, 2nd local oscillations’ signals, limiting
amplifier, orthogonal intersection detector and RSSI(Receiving Signal Strength Indicator). The 2nd
mixer mixes the 1st intermediate frequency signal and the 2nd local oscillations’ signals output, and
then creates the 2nd intermediate frequency signal 450KHz. The 2nd intermediate frequency signal
continuously eliminate the signals from the adjacent channels via ceramic filter(FL5156). The 2nd
intermediate signal through filter is enlarged by limiting amplifier and demodulated by orthogonal
detector with chinaware discriminator (CR515). The demodulated signal enters the tone circuit.(See
Chart II)
（5）ToneAmplifier Circuit
For U band, after transmitting to the tone processor U512 to process the circuit, the demodulated
signal outputs to U723 volume control IC from the 23rd foot tube, and outputs to speaker after being
enlarged by tone power amplifier (U742).
For V band, after transmitting to the tone processor U460 to process the circuit, the demodulated
signal outputs to U723 volume control IC from the 23rd foot tube, and outputs to speaker after being
enlarged by tone power amplifier (U742).（See Chart II）
(6) Squelch
For U band, FM IC (U524) and V band, a part of AF signal outputted by FM IC(U460) enters IC again.
Noise components are amplified and amended via filter and amplifier, and creates the appropriate DC
voltage with the noise PWL.
DC signal is sent to the 18th foot analogue port of tone processor IC (U512) via FM IC. U912
determines if outputs the voice via speaker by checking the inputted data by the tone processor IC
(U512). When the speaker outputs voice, the 14th foot of microprocessor (U912) transmits the high
level signals to P-SPK1 line, and opens AF AMP (U742) via T737. See Chart III

III Synthesis of PLL Frequency
PLL circuit creates the local oscillator signals for receiving and RF signals for transmitting.
Chart IV
(1) PLL
The step frequency for PLL circuit is 5KHz or 6.25KHz.
Reference oscillation signals of 14.4MHz and 19.2MHz are split frequencies by a fixed counter on
U111 and U114. The outputted signals from VCO of V/U band oscillator are respectively buffered and
amplified by T116 and T115, and then are split frequencies by a programmable two-module counter on
U111 and U114. The signals of splitting frequencies are separately compared in the phase comparator
of U111 and U114. The two created signals go through different low pass to filter, and then separately
transmits to U/V VCO to control the oscillation frequencies.( See Chart IV)
(2) VCO
cVCO for U Band
For U band, the used frequency points are created by T113 for transmitting and receiving.
Transmit the VCO controlling voltage that is obtained from the phase comparator to variable diode
(D116, D112) to control oscillation frequency. The signals from the oscillated frequency are amplified

by T116 and T117, and then are transmitted to RF amplifier and receiver separately via D142 and
D135. ( See Chart IV)
dVCO for V Band
For V band, the used frequency points are generated by T134 for transmitting and receiving.
Transmit the VCO controlling voltage that is obtained from the phase comparator to variable diode
(D116, D114) to control oscillation frequency. The signals from the oscillated frequency are amplified
by T116 and T117, and then are transmitted to RF amplifier and receiver separately via D144 and
D122. ( See Chart IV)
IV Transmitting Segment System
(1) Speaker Amplifier
The signals from the speaker via U611 are adjusted maximum frequency deviation by U band tone
processor (U512) and V band tone processor (U460), and then are sent to VCO of U or V band to
modulate and input. (See Chart V)
Chart V
(2) Driver and Terminal Amplifier
cThe signals from U band T/R switch (D142 ON) are amplified by pre-driver amplifier (T139,
T2140). The signals from V band T/R switch (D144 ON) are amplified by pre-driver amplifier (T138).
The amplified U/V signals are separately transmitted to the driver amplifier (T325, T326) to 5W.
The output of the driver amplifier is amplifier to 50W（when on low power level, it is 25W）by RF
power amplifier (T331). For U band, the output of RF power amplifier passes harmonic filter(LPF)
and antenna switch(D332, D333), and then is sent to antenna terminal. For V band, the output of RF
power amplifier passes harmonic filter (LPF) and antenna switch (D335, D335), and then is sent to
antenna terminal.(See Chart VI)

ChartVI
(3) Auto Power Control (APC) Circuit
For U band, a part of the output from RF power amplifier is commuted to DC voltage by D340, D341
and T336, and then is sent to APC IC312. APC IC312 produces a controlled voltage by comparing DC
voltage and the 3rd output reference voltage from U723 D/A converter. And the controlled voltage is
provided by auto power controlled tube T327, T328, pre-driver amplifier T325, driver amplifier T326
and power amplifier T331.So that it still can continuously output stable power under the changing
antenna loading condition.
For V band, a part of the output from RF power amplifier is commuted to DC voltage by D341, D342
and T336, and then is sent to APC IC312. APC IC312 produces a controlled voltage by comparing DC
voltage and the 3rd output reference voltage from U723 D/A converter. And the controlled voltage is
provided by auto power controlled tube T327, T328, pre-driver amplifier T325, driver amplifier T326
and power amplifier T331.So that it still can continuously output stable power under the changing
antenna loading condition. (See Chart VI)
(4) Encoding Signaling
QT/DQT
For U band, DQT/QT data is outputted by the 13th tube foot of tone processor IC U512. A part of
signals are sent to TCXO CR111 via IC U523B. Another part of signals are mixed with tone signals,
and then separately is inputted to VCO of U band.
For V band, DQT/QT data is outputted by the 13th tube foot of tone processor IC U460. A part of
signals are sent to TCXO CR111 via IC U523A. Another part of signals are mixed with tone signals,
and then separately is inputted to VCO of V band.
V Power Supply
The radio can control the power supply via the POWER key on the panel.
There are most-used power supplies 8V and 5V.
5C-V is the public 5V for V band, which keeps outputting in the un-saving mode.
5R-V is the public 5V, which keeps outputting during receiving. 5R-U is 5V for receiving on U band,
and keeping outputting during receiving.
8T-V is the 5V for transmitting on V band, which keeps outputting during transmitting. 8T-V is also
