KG-UVD1 Dual-Band Maintenance Manual

Introduction

The Scope for the Manual

This manual is for the technicians who know well about the communication and have some experiences of maintenance. All necessary information of maintenance and actual published date are included in this manual.

If there is any change after publishing, we will complement it by “Maintenance Aviso” or “Manual Revision” according to the requirements.

Personal Safety

● Please pay attention to the below proceedings for your safety:

Don’t transmit before you carefully check all plugs for TX Frequency, or any of the unfolded plugs doesn’t connect to the relative ends.

● Please turn off the power, and don’t operate the equipment when you are near the electric detonator or on flammability gas station.

●Only the qualified technicians can maintain the equipment.

Maintenance Service

In order to maintain the equipment easily and establish the complete maintenance system, we supply the information including principium chart, printing circuitry chart and the settings of the equipment.

Duplication Mode

1. “Duplication Mode” can copy the data of a handheld transceiver to another one.

The dealers can do this duplication without a personal computer.

2. Operating Method

①Connectting the duplicated source radio with waiting-duplicated target radio by cloning Line

（The waiting-duplicated target radio need to be putting through the power source）



When duplicating, the flickering red light means sending data. After duplicating successfully, the red light extinguishes, and the source radio enters the standby mode. If the red light keeps flickering, it means the duplication failed.

The green light flickers when the target radio duplicates. The duplication finishes when the green light extinguishes.

WOUXUN

(1) The front end of U Band (RF Amplifier)

The signal which is received from the antenna enters the transmission/receive change-over switch diode circuit

(D148, D137, D138 and D147), then goes through BPF (L191 and L192), and is enlarged by RF amplifier (T322).

The signal goes through the BPF(L185,L189,L187,L188), and then enters the mixing. These BPF (D142, D143,

D144, D145) is adjusted by the variable condenser. The input voltage by variable condenser is adjusted by the outputting voltage by microprocessor (IC811).( See PIC 2)

(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

(D322，D315，D316 和 D443), then goes through BPF(L344 and L345), and is enlarged by RF amplifier (T324).The signal goes through the BPF(L320，L342,L341 L340), and then enters the mixing. These BPF (D318

(3) The 1 st

Mixer

The signals from the front end of U Band and the Rx LO prouduced by PLL electrocircuit creat the 1 st

immediate frequency signal of 29.250MHz on T144 Mixing. The created signal is sent to the changeover on-off on U/V Band.

The signals from the front end of V Band and the Rx LO prouduced by PLL electrocircuit creat the 1 st

immediate frequency signal of 29.250MHz on T323 Mixing. The created signal is sent to the changeover on-off on U/V Band.

The changeover on-off switches the signals according to the working state of U/V Band on microprocessor (IC811).

After switching, the signals are sent to MCF(FL515,FL516) (See PIC2)

（ 4 ） The enlarging circuit on Intermediate Frequency

The first signal from intermediate frequency eliminate the signals from adjacent channels through

MCF(FL515,FL516). The amplifier (T520) enlarges and enters the I-F system chip (U516). The I-F system chip provides the second mixer, the second LO signal, limiting amplifier, orthogonal detector and RSSI (received signal intensity indicator).The second mixer sends and mixes the first intermediate frequency signal and the second LO signal of 28.8MHz, and then creates the second LO signal of 450kHz.

The second intermediate frequency signal keeps eliminating the signals of the adjacent channels by the chinaware wave filter. The second signal through filter is enlarged by limiting amplifier and demodulated by orthogonal detector with chinaware discriminator. The demodulated signal enters the tone circuit on microprocessor (IC811) and processes.(See PIC2)

T528 is disconnected when receiving the data from NARROW (high level).

T528 is connected/ disconnected by WIDE/NARROW data.The regular changing level from U516 detector is used to maintain the constant output level on WIDE/NARROW signals. (See PIC3)

Squelch

A part of AF signals from FM IC (U516) enter IC again. The noise components are enlarged and revised by the filter, and then creates the DC voltage corresponded to the noise level.

The DC signal is sent to the simulated port （Pin28） of microprocessor through FM IC. IC405 decides whether outputs the sound from the speaker by testing the outputted voltage is higher or lower than the default value.

The signal from the oscillator (VCO) is cushioned and enlarged by T130 and T311 separately, and is divided frequency by programmable double modulation arithmometer separately in U112. In the U112 phase comparator, the frequency division processes compare. After being filtered by the different lowpass, the two created signals separately are sent to the two independent VCO controlling frequency of oscillator. See PIC 5

(T141). The output of drive amplifier is enlarged to 4.0W by the RF power amplifier (T142) (works as when low power is 1W). The output of RF power amplifier is through the harmonic filter (LPF) and the antenna switch (D148), and is sent to the terminal of the antenna .

（3）Automatic Power Control Circuit (APC)

APC circuit always monitor the circuit that is through the radio frequency RF amplifier (T142 or T322),and maintain the stable electric current. The diversification of electronic current that is enlarged by radio frequency power amplifier can cause the lower voltage of R615, R616, R659 and R660. The voltage is sent to difference amplifier

U612(2/2) U612(1/2), and compares the outputting voltage of IC101(2/2) with the reference voltage from IC405.

The output voltage of U612 (1/2) control the radio frequency RF amplifier, drive amplifier, VG of pre-drive amplifier to keep the voltage consistent.

The changes of high/low power are realized by changing the reference voltage.

The two terminal amplifiers of this transceiver use the same APC circuit. So they are switched on the output VG voltage from APC. When U Band transmitting, the VG voltage that sends APC to V Band
