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

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.
