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.

Alignment

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.
