PA Unit Adjustment
Preparation
Connect the 50-Ohm Dummy Load and Watt-
meter to the “ANT 1” jack.
Disconnect the coaxial cables from J5001 and
J5007 on the PA Unit, then terminate J5001 and
J5007, each with a 50-Ohm resistor.
Disconnect the jumper plugs from J5003 and
J5005 on the PA-A Unit.
Pre-Drive Stage Idling Current Adjustment
Connect the DC ammeter to J5003 on the PA
Unit.
Press and hold in the [1.8(1)], [3.5(2)], and [7(3)]
keys, while turning the radio on, to enter the
alignment mode.
Rotate the Main Tuning Dial knob to select the
alignment parameter “8-01 PDR”.
Press and hold the PTT button, while adjusting
the [VFO-B/CLAR] knob so the DC ammeter
reading is “100 mA (±5 mA)”.
Release the PTT button.
Drive Stage Idling Current Adjustment
Connect the DC ammeter to J5005 on the PA
Unit.
Rotate the Main Tuning Dial knob to select the
alignment parameter “8-02 DR1”.
Press and hold the PTT button, while adjusting
the [VFO-B/CLAR] knob so the DC ammeter
reading is “700 mA (±50 mA)”.
Release the PTT button.
Rotate the Main Tuning Dial knob to select the
alignment parameter “8-03 DR2”.
Press the PTT button, then adjust the [VFO-B/
CLAR] knob so that the DC ammeter reading is
“700 mA (±50 mA)”.
Release the PTT button.
