CIRCUIT DESCRIPTION

DISASSEMBLY FOR REPAIR

Beat Shift Circuit

To prevent VGS-1 clock oscillation for the MCU (IC2)

from causing spurious reception to transceivers to which

VGS-1 is connected, the clock oscillator (11.0592MHz) has a

beat shift circuit with a transistor switch (Q1).

■Beat Shift Circuit Off by MCU

When pin 94 of the MCU (IC2) goes Low level, Q2 turns

off and Q1 turns on because a 5V bias is applied to its base.

In this condition, C10 is shorted, so the oscillation frequency

is unchanged.

■Beat Shift Circuit On by MCU

When pin 94 of the MCU goes High level, Q2 turns on

and Q1 turns off because its base is pulled down to GND.

In this condition, C10 is connected in series to the crystal

oscillator and the oscillation frequency increases by approx.

150ppm.

■Beat Shift Circuit On/Off with External Device

When pin 94 of the MCU is in the Low level state, the

beat shift circuit turns on by designating pin 17 of the con-

How to Distinguish Between the Old and

New VGS-1

Precautions When Repairing the VGS-1

• When you repair VGS-1 used by Amateur transceivers,

install it in the Amateur transceiver if it is necessary to

install the VGS-1 in the transceiver.

• When you repair VGS-1 used by Land mobile transceiv-

ers, install it in the Land mobile transceiver if it is neces-

sary to install the VGS-1 in the transceiver.
