Page 3: Circuit Description
CIRCUIT DESCRIPTION 1) [RX] 1. RX Method: Double Super Heterodyne Method 1st IF FM 39.15 MHz 2nd IF 2. Front End The signal input from antenna passes through the duplexer FL1 and low pass filter, then it is amplified at RF amplifier Q17. The amplified signal is led to band pass filter and band switch D19, then input to the mixer Q16. - Page 4 5. Squelch Q24 determines the gain of AF signal output from pin 12 of IC5 according to the WFM/NFM of IC8. Then the signal is input to pin 19 of IC5. The input signal passes through the noise filter amplifier and rectifier circuit, then output from pin 21 of IC5.
- Page 5 IC2 compares the frequency gained by dividing the signal added to pin 19 of IC2 by the control signal from IC6 with the frequency gained by dividing the reference frequency of 12.9 MHz 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 13 of IC2, then the signal is converted into the DC voltage at the inside circuit for passive filter and added to the cathode side of...

Page 27: Entering And Releasing The Adjustment Mode
2) Entering and releasing the adjustment mode The DJ-596 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 made by using the keys on it while the unit is in the adjustment mode. - Page 28 Reference frequency adjustment 1. In the adjustment mode, select channel 1 by rotating the main tuning dial. 2. Press the key to start transmission. 3. Rotate TC1 on the main board until the value on the frequency counter matches the one displayed on the LCD. UHF high-power adjustment 1.
- Page 29 VHF minimum frequency sensitivity adjustment See “Note on adjusting the sensitivity” later in this section. 1. In the adjustment mode, select channel 6 by rotating the main tuning dial. 2. Set the minimum frequency sensitivity rotating the main tuning dial, while F appears after the key is pressed.
- Page 30 VHF S-meter (FULL) adjustment 1. In the adjustment mode, select channel 13 by rotating the main tuning dial. The S-meter will show all circles ( 2. Enter “+20” dBµ (EMF) with the transceiver tester (SSG). 3. Press the key. The transceiver beeps indicating the new setting has been stored successfully.
- Page 31 UHF narrow deviation adjustment 1. In the adjustment mode, select channel 19 by rotating the main tuning dial. 2. Input a 50mVrms, 1kHz signal with your transceiver tester through the external microphone jack. 3. With the tester, put the transceiver in the transmission mode. 4.
- Page 32 Tone 88.5Hz test 1. In the adjustment mode, select channel 23 by rotating the main tuning dial. 2. Press the key. An 88.5Hz tone is automatically sent. 3. Check the deviation with the transceiver tester, and make sure the deviation level is within 0.4 to 1.2kHz range.
