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-A
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".
P r e s s t h e P T T b u t t o n , t h e n a d j u s t t h e
[CLAR(VFO-B)] knob so that the DC ammeter
reading is "100 mA (±5 mA)".
Release the PTT button.
J5007
Drive Stage Idling Current Adjustment
Connect the DC ammeter to J5005 on the PA-A
Unit.
Rotate the Main Tuning Dial knob to select the
alignment parameter "8-02 DR1".
P r e s s t h e P T T b u t t o n , t h e n a d j u s t t h e
[CLAR(VFO-B)] knob so that 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".
P r e s s t h e P T T b u t t o n , t h e n a d j u s t t h e
[CLAR(VFO-B)] knob so that the DC ammeter
reading is "700 mA (±50 mA)".
Release the PTT button.
