PLL & Transmitter
Set up the test equipment as shown for transmitter alignment.
Maintain the supply voltage at 13.6 V DC for all steps.
PLL VCV
･ ･･ ･
Connect the positive lead of the DC voltmeter to the test point TP1007 (VCV) on the Main
Unit, as indicated in the figure, and the negative lead to chassis ground.
･ ･･ ･
Set the transceiver to the high band edge frequency channel, then adjust trimmer-capacitor
L1021 on the Unit for 7.0 V on the voltmeter.
･ ･･ ･
Key the transmitter, and adjust trimmer-capacitor L1022 on the Unit for 7.0 V on the
voltmeter.
･ ･･ ･
Next select to the low edge frequency channel and confirm about 1.8 V (1.5 V to 2.1 V) on
the voltmeter.
･ ･･ ･
Key the transmitter, and confirm about 1.8 V (1.5 V to 2.1 V) on the voltmeter.
PLL Reference Frequency
With the wattmeter, dummy load and frequency counter connected to the antenna jack, and
select band center frequency channel, key the transmitter and adjust TC1001 on the Main Unit,
if necessary, so the counter frequency is within ±100 Hz of the channel center frequency for the
transceiver version.
Transmitter Output Power LVHF
･ ･･ ･ 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
120 ±2 Watts 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
50 ±1 Watts as indicated on the wattmeter.
