PLL & Transmitter
Set up the test equipment as shown for transmitter alignment.
Maintain the supply voltage at 13.8 V DC for all steps.
PLL VCV
Connect the positive lead of the DC voltmeter to the test point TP1010(VCV) on the Main Unit, as
indicated in the figure, and the negative lead to chassis ground.
Set the transceiver to the band high edge（center） frequency channel(CH2), then adjust T1011 on the
Unit for 7 V on the voltmeter.
Key the transmitter to the band high edge frequency channel(CH4)and adjust T1006 on the Unit for 7 V
on the voltmeter.
Next select to the band high edge frequency channel(CH4), then adjust T1005 on the Unit for 7V on the
voltmeter.
Next select to the band low edge frequency channel(CH1) and confirm about 3.1 V (2.8V – 3.4V) on the
voltmeter.
Next select to the high band (low edge ) frequency channel(CH3) and confirm about 3.7 V (3.4V – 4.0V)
on the voltmeter.
Key the transmitter, and confirm about 7 V (6.9 V – 7.1 V) on the voltmeter.
Transmitter Output Power
Select band center frequency channel, and select high power output level.
Key the transmitter and adjust by control commands for high power from the computer for 70 ± 2 W as
indicated on the wattmeter.
Select band center frequency channel, and select low power output level.
Key the transmitter and adjust by control commands for low power from the computer for 30 ± 1 W as
indicated on the wattmeter.
Transmitter Deviation
Microphone Audio Modulation Level
Select band center frequency channel, and adjust the AF generator for 25 mV (-30 dBm) output at 1 kHz
to the microphone jack.
Key the transmitter and adjust by control commands for maximum deviation from the computer for 4.2 kHz
± 0.2 kHz deviation as indicated on the deviation meter.
