Alignment
ALIGNMENT-6

Rotate the [VFO-B/CLAR] knob so that the DC
voltmeter reading is “0.620 – 0.625 V”.

Rotate the Main Tuning Dial knob to select the
alignment parameter “2-04 Local14”.

Rotate the [VFO-B/CLAR] knob so that the DC
voltmeter reading is “0.640 – 0.645 V”.

Rotate the Main Tuning Dial knob to select the
alignment parameter “2-05 Local21”.

Rotate the [VFO-B/CLAR] knob so that the DC
voltmeter reading is “0.620 – 0.625 V”.

Rotate the Main Tuning Dial knob to select the
alignment parameter “2-06 Local28”.

Rotate the [VFO-B/CLAR] knob so that the DC
voltmeter reading is “0.600 – 0.605 V”.

Rotate the Main Tuning Dial knob to select the
alignment parameter “2-07 Local50”.
(Set the VFO-A frequency to 28.850 MHz.)

Rotate the [VFO-B/CLAR] knob so that the DC
voltmeter reading is “0.520 – 0.525 V”.
(Set the VFO-A frequency to 50.500 MHz)

Press and hold in the [MENU] button for one
second to save the new settings and exit the
alignment mode.
2nd Local Level Adjustment

Connect the RF millivoltmeter to TP1062 on the
MAIN Unit.

Adjust T1032 on the MAIN Unit for maximum
deflection on the RF millivoltmeter (+6 - 14
dBm).
3rd Local Level Adjustment

Connect the RF millivoltmeter to TP1058 on the
MAIN Unit.

Adjust T1029 on the MAIN Unit for maximum
deflection on the RF millivoltmeter (+6 to 14
dBm).
IF Transformer Adjustment

Set the VFO-A frequency to 14.200 MHz in the
CW-USB mode.

Set the following controls as indicated:
[ANT] : ANT 1
[IPO] : AMP1
[ATT] : OFF
[R.FLT] : 3 kHz
[AGC] : AUTO
[RF GAIN] : Fully clockwise

Connect the AF millivoltmeter and 4 Ohm
dummy load to the EXT SP jack.

Connect the RF Signal Generator to the “ANT 1”
jack, then set the output level to +5 - -10 dBµ at
the 14.200 MHz.

Adjust T1034 and T1025 on the MAIN Unit
in succession several times for maximum
deflection on the AF millivoltmeter.
Note : If the S-meter deflects while adjusting,
reduce the RF Signal Generator output so that the
S-meter does not deflect.
