Alignment
Noise Blanker Circuit Adjustment
Set the following controls as indicated:
[ANT 1/2] button: ANT 1
[IPO] button: AMP1
[ATT] button: OFF
[AGC] button: "Sub band (VFO-B)"AUTO
[NB] button: "Sub band (VFO-B)" ON
(for short-duration pulse noise)
[NB] knob: Fully clockwise
[RF GAIN] knob: Fully clockwise
[SUB RX] button: ON
Set the Sub Band (VFO-B) frequency to 14.200
MHz in the CW mode.
Connect the DC voltmeter to TP4505 on the RX-2
Unit.
Connect the RF Signal Generator to the "ANT 1"
jack, then set the output level to 30 dBµ at the
14.200 MHz.
Adjust T4508 and T4512 on the RX-2 Unit for
minimum deflection on the DC voltmeter.
Turn the Sub band´s (VFO-B) NB to "OFF" by
pressing the [B] button followed by the [NB] but-
ton.
IF Gain Adjustment
Set the following controls as indicated:
[ANT 1/2] button: ANT 1
[IPO] button: AMP1
[ATT] button: OFF
[AGC] button: "Sub band (VFO-B)"AUTO
[PITCH] knob: 700 Hz
[RF GAIN] knob: Fully clockwise
[SUB RX] button: ON
Connect the AC 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 36 dBµ at the
1.900 MHz.
Set the Sub Band (VFO-B) frequency to 1.900 MHz
in the CW mode.
Press and hold in the [1(1.8)], [2(3.5)], and [3(7)]
keys, while turning the radio on, to enter the
alignment mode.
Adjust the Sub [AF GAIN] knob so that the AC
millivoltmeter reading is "0 dB."
ALIGNMENT-10
Select the appropriate "Alignment Parameter"
using the Main Tuning Dial knob per the chart
below, then set the RF Signal Generator output
to each listed level, and adjust the [SUB(VFO-B)]
knob for the corresponding AC millivoltmeter
reading at each frequency.
