CIRCUIT DESCRIPTION
1) Reception
1. RX M ethod
[FM/AM]
Double Super Heterodyne Method
1st IF: 50.85MHz
2nd IF: 450kHz
[WFM]
Single Super Heterodyne Method
1st IF: 10.7MHz
2. Fro nt End
[WFM BAND]
The signal input from antenna passes through the low pass filter, and then it is
amplified at RF amplifier Q13. The amplified signal is led to band pass filter
and band switch D17, then input to the mixer IC3.
[VHF BAND]
The signal input from antenna passes through the low pass filter, and then it is
amplified at RF amplifier Q18. The amplified signal is led to band pass filter
and band switch D17, then input to the mixer IC3.
3. M ixer
[UHF BAND]
The signal input from antenna passes through the band pass filter, and then it
is amplified at RF amplifier Q21. The amplified signal is led to band pass
filter and band switch D29, then input to the mixer IC3.
[FM/AM]
The input signal to the mixer IC3 and the 1st local signal are added or
subtracted at mixer IC3, and the crystal filter FL1 selects the signal of 50.85
MHz, then it is amplified at the 1st IF amplifier Q15 after the adjacent signal
is eliminated.
[WFM]
The input signal to the mixer IC3 and the 1st local signal are added or
subtracted at mixer IC3, and the ceramic filter FL2 selects the signal of
10.7MHz, then it is amplified at the 1st IF amplifier Q14 after the adjacent
signal is eliminated.
3
4. IF
[FM/AM]
The signal amplified at the 1st IF amplifier Q15 is supplied to pin 24 of IC7
for demodulation. Also the signal of 12.6 MHz from the reference buffer
output of IC2 is multiplied by 3 at Q12, and then it is led to pin 1 of IC7. 2
input signals are mixed in the mixer circuit inside IC7 and converted into the
2nd IF signal of 450kHz.The converted 2nd IF signal is output from pin 3 of
IC7.
[FM]
The output signal from pin 3 of IC7 is led to pin 7 of IC7 after eliminating the
adjacent channel signal at the ceramic filter FL3. The input 2nd IF signal to
pin 7 of IC7 is demodulated at the limiter amplifier and quadrature detector
circuits inside of IC7, then output from pin 12 of IC7 as an AF signal.
[AM]
The output signal from pin 3 of IC7 is led to the pin 5 of IC7 after eliminating
the adjacent channel signal at the ceramic filter FL3. The 2nd IF signal input
to pin 5 of IC7 is AM-demodulated inside of IC and output from pin 13 of
IC7 as an AF signal. The 1st IF amplifier Q15 is controlled by reverse AGC at
AGC amplifier Q19 to get better audio output even though the input is
changed, and the gain is controlled.
[WFM]
The signal amplified at the 1st IF amplifier Q14 is supplied to pin 7 of IC7 for
demodulation.
The input 2nd IF signal to pin 7 of IC7 is demodulated at the limiter amplifier
and quadrature detector circuits inside of IC7, then output from pin 12 of IC7
as an AF signal.
5. Squelch
6. Audio
The AF signal got from pin 12 of IC7 is fed to pin 19 of IC7. The input signal
is output from pin 21 of IC7 passing through the noise filter amplifier and
rectifier circuits inside of IC7. The rectified signal is added to the A/D port of
the microcomputer IC6. Judging the signal, the microcomputer controls
ON/OFF of the audio output.
[FM/AM/WFM]
The selection of receiving audio output signal between FM/WFM and AM is
performed at IC8. The volume of output audio signal is adjusted at the
electronic volume IC14 via the AF amplifier Q27. The signal is input to pin 2
of audio power amplifier IC12 and output from pin 6 to drive a speaker, etc.

7. VCO
8. P LL
[VHF]
VCO in VHF band consists of the Colpitts oscillator. D3, D4 and L11
determine the oscillating frequency, and the signal is oscillated at the
transistor Q2. The oscillated signal is supplied to pin 8 of PLL-IC2 passing
through the buffer amplifier Q5 and Q4.
[UHF]
VCO in UHF band consists of the Colpitts oscillator. D9, D11 and L18
determine the oscillating frequency, and the signal is oscillated at the
transistor Q7. The oscillated signal is supplied to pin 8 of PLL-IC2 passing
through the buffer amplifier Q5 and Q4.
PLL-IC2 is used to control the oscillating frequency of VCO. IC2 is
controlled by the serial control signal sent from the microprocessor IC6. The
12.6MHz reference frequency of IC2 oscillates the crystal oscillator X1 at the
inside circuit.
[VHF]
IC2 compares the frequency gained by dividing the signal added to pin 8 of
IC2 by the control signal from IC6 with the frequency gained by dividing the
reference frequency of 12.6MHz inside IC2. When the phase difference is
found as a result of phase comparison, the pulse signal is output from the
charge pump output of pin 5 of IC2, then the signal is converted into the DC
voltage at the passive filter and added to the cathode side of VCO
variable-capacitor D3 and D4 to make the phases equal. In result the
stabilized oscillation can be done at the desired frequency.

2) Transmitter
1. M icrophone Amplifier
2. Power Amplifier
The microphone amplifier IC301 has 2 operational amplifiers. The voice is
converted into the electric signal through the microphone, and then supplied
to IC301. The input signal is amplified and pre-emphasized to be output.
[VHF]
The signal output from microphone amplifier is adjusted the maximum
frequency deviation at VR2. The adjusted signal is added to the cathode of
VCO variable-capacitor D4 for deviation to change the capacity of the
oscillation circuit resulting the FM deviation.
[UHF]
The signal output from microphone amplifier is adjusted the maximum
frequency deviation at VR1. The adjusted signal is added to the cathode of
VCO variable-capacitor D10 for deviation to change the capacity of the
oscillation circuit resulting the FM deviation.
The oscillated signal at VCO is supplied to the power amplifier Q3, passing
through buffer amplifier Q5, driver amplifier IC1. The power-amplified signal
is supplied to the antenna through the duplexer after the harmonics are
attenuated enough.

2) Entering and Releasing the Adjustment Mode
The DJ-C7 does not require a serviceperson to manipulate the components on the printed-circuit board, except
the trimmer when adjusting reference frequency and deviation. Most of the adjustments for the transceiver are
mode by using the keys on it while the unit is in the adjustment mode. Because the adjustment mode
temporarily uses the channels, frequency must be set on each channel before adjustments can be mode. For
instructions on how to program the channels, see the “DJ-C7 INSTRUCTION MANUAL” which came with the
product. In consideration of the radio environment, the frequency on each channel must be near the value
(+/-1MHz) listed in the table below. To enter the adjustment mode, set key lock and press [BAND], [V/M],
[SCAN], [V/M], [SCAN], [BAND], and [FUNC] key. “Freq” appears in LCD. When changing the adjustment
parameters, press the [SCAN] or [BAND] key.
To exit the adjustment mode, press the [MONI] key.
