PLL VCV (Varactor Control Voltage)

❒ Connect the DC voltmeter between TP1045 on the

Main Unit and ground.

❒ Set the transceiver to CH 3 (high band edge), and ad-

just L1036 on the Main Unit for 4.0 V ± 0.1 V on the
DC voltmeter.

❒ Set the transceiver to CH 1 (low band edge), and con-

firm the low-end VCV is more than 0.9 V while re-
ceiving.

❒ Set the transceiver to CH 3 (high band edge), and ad-

just L1038 on the Main Unit for 4.0 V ± 0.1 V while
transmitting.

❒ Set the transceiver to CH 1 (low band edge), and con-

firm the low-end VCV is more than 0.9 V while trans-
mitting.

Reference Frequency

❒ Set the transceiver to CH 2 (band center) via the “CH”

box on the “Alignment” window previously.

❒ To adjustment, click the left mouse button on the “RF

Frequency

” box, then press the [ENTER] key to open

the pop-up window.

❒ Use the [ ] or [ ] arrow keys so that the frequency

counter displays the band center frequency (±100 Hz)
for the version being aligned.

❒ Press the “OK” box to lock in the new data.

Transmitter Output Power

❒ Set the transceiver to CH 2 (band center).

❒ To adjustment, click the left mouse button on the “RF

Power {High}

” or “RF Power {Low}” box, then press

the [ENTER] key to open the pop-up window.

❒ Use the [ ] or [ ] arrow keys so that the power meter

reading is 5.0 W (± 0.1 W) (for “RF Power High”) or
1.0 W (± 0.1 W) (for “RF Power Low”). Confirm that
the current consumption is 2.3 A or lower (for “RF
Power High”) or 1.0 A or lower (for “RF Power Low”).

❒ Press the “OK” box to lock in the new data.

MAX Deviation

❒ Set the transceiver to CH 2 (band center).

❒ Inject a 1 kHz tone at –17 dBm to the MIC jack.

❒ To adjustment, click the left mouse button on the “MAX

Deviation

” box, then press the [ENTER] key to open

the pop-up window.

❒ Use the [ ] or [ ] arrow keys so that the deviation

meter reading is ±4.2 kHz (±0.1 kHz) (for 25 kHz steps)
or ±2.1 kHz (±0.1 kHz) (for 12.5 kHz steps) deviation.

❒ Press the “OK” box to lock in the new data.
