ALIGNMENT

The FT-23R has been carefully aligned by

highly skilled techniciens ai the factory, and

is designed so that no further alignment

should ever be required. However, in the

unlikely event of a component failure, re-

alignment may be necessary. Ali component

replacement and service should be pcrformed

only by an authorized Yaesu représentative, or

the warranty pollcy may be voided.

The following test equipment is required for

alignment:

RF Signal Generator:

calibrated output level at 150 MHz

Deviation Meter (linear detector)

Oscilloscope

AF Millivoltmeter

SIN AD Meter

Inline Wattmeter: 150 MHz

Regulated D Power Supply:

adjustable from 4 to 17V, 2A

50-ohm Non-reactive Dummy Load: I0W at 150 MHz

Frequency ounter: 0.2ppm accuracy at 150 MHz

AF Signal Generator

D Voltmeter: high impédance

ASE D1SASSEMBLY

Make sure the transceiver is off. Remove

the hard or soft case, if used, and remove

the battery pack.

Remove the four screws affixing the battery

spring plate on the bottom of the transcei

ver, and carefully remove the plate.

Remove the four screws affixing the top

panel, and carefully remove the panel.

Remove the two screws affixing the front

and rear halves of the case, and gently

separate the halves, using care not to

stress the interconnecting wires.

I. PLL & TRANSMITTER

Set up the test equlpment as shown in the

diagram below for transmuter alignment. Ad

just the supply voltage to 12.0V for all steps

except Transmitter Output Power alignment (В).

Л. PLL V V (Varactor ontrol Voltage)

(1) onnect the D Voltmeter between 416 on

the PLL Unit and chassis ground.

(2) Whlle transmitting on 144.000 MHz adjust

transformer T501 on the V O Unit for 1.35

:0.05 VD .

(3) While receiving on 144.000 MHz adjust

trimmer T 501 on the V O Unit for 1.1

гО.05 VD .

(4) Retune the transceiver and confirm the

high-end V V for the transceiver version

being aligned, as follows:

Version Frequency Tx V V Kx V V

A. . K 148.000 1.8 V 1.6 V

B. D 146.000 1.7 V 1.5 V

PLL & TRANSMITTER ALIGNMENT SETUP

Sampling

B. Transmitter Output Power

(1) Tune the transceiver to band center (145

or 146 MHz), and set the LOW switch to

the undepressed position.

(2) Increase the supply voltage to 12.5V.

(3) Adjust T I0I on the Mother Board for peak

output power on the Wattmeter (at least

5W with less than 1.5A supply current).

(4) Press the LOW switch on the top panel,

and adjust VR105 on the Mother Board for

0.5 watts output.

(5) Return the supply voltage to 12.0V.

. PLL Reference Frequency

With the transceiver tuned to band center (145

or 146 MHz), adjust T 40I on the PLL Unit, if

necessary, so that the display frequency mat-

ches the frequency counter when transmitting.

D. Modulation Level

( I ) With the transceiver tuned to band center

(145 or 146 MHz), adjust the AF generator

for 25mV output ai 1 kHz to the MI Jack.

(2) Adjust VRI04 on the Mother Board for ±4.5

kHz déviation on the déviation meter.

S-meter Sensitiviiy

Set up the test equipment as shown above for

receiver allgnment.

A. Sensitivlty

(1) With the transceiver and RF signal gen

erator both tuned to band center (145 or

146 MHz), set the generator for ±3.5 kHz

déviation of I kHz tone modulation, and

set the output level for 40 dBu at the

antenna jack.

(2) Preset VR103 on the Mother Board fully

clockwise.

(3) Adjust TI01 through T104 on the Mother

Board for maximum S-meter Indication,

reducing the generator level If more than

four bargraph segments turn on.

After step (3), generator level should be 0.2

uV or less for !2dB SINAD. Perform the follow-

ing adjust ment next.

II. RECEIVER

(1) With the transceiver and RF signal gen

erator set up as in step ( 1 ) of the above

Sensitivity adjustment procedure, set the

signal generator for 20 dBu output.

(2) Adjust VR103 on the Mother Board so that

all bargraph segments are just turned on.

(3) Reduce the generator output so that only

two bargraph segments are on, and conflrm

that the generator output level is now 5

dBu or less.
