Noise Blanker Circuit Adjustment
Set the following controls as indicated:
[IPO] button: AMP1
[ATT] button: OFF
[R.FLT] button: AUTO
[AGC] button: AUTO
[NB] button: ON (for short-duration pulse noise)
[NB] knob: 12 o' clock
[RF GAIN] knob: Fully clockwise
[VRF] button: THRU
Set the Main Band (VFO-A) frequency to 14.200
MHz in the CW mode.
Connect the DC voltmeter to TP3020 on the
MAIN Unit.
Connect the RF Signal Generator to the “ANT 1”
jack, then set the output level to 20 dBµ at 14.200
MHz.
Adjust T1019, T3023 and T3028 on the RX-1 Unit
for minimum deflection on the DC voltmeter.
Turn the NB to “OFF” by pressing the [NB] but-
ton.
Disconnect the RF millivoltmeter from TP3020.
IF Trap (9MHz) Adjustment
Set the following controls as indicated:
[IPO] button: AMP2
[ATT] button: OFF
[R.FLT] button: AUTO
[AGC] button: AUTO
[RF GAIN] knob: Fully clockwise
[VRF] button: THRU
Set the Main Band (VFO-A) frequency to 10.000
MHz in the CW mode.
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 60 dBµ ~ 90 dBµ
at 9.000 MHz.
Adjust T3005 on the MAIN Unit for minimum
deflection on the AC millivoltmeter.
If the Main S-meter deflects while adjusting, re-
duce the RF Signal Generator output so that the
Main S-meter does not deflect.
IF OUT Adjustment
Set the following controls as indicated:
Menu item: 109 RGEN IF OUT (ENABLE)

[VRF] button: THRU
Connect the RF millivoltmeter to TP3037 on the
RX-1 Unit.
Set the Main Band (VFO-A) frequency to 14.200
MHz in the CW mode.
Then set the output level to 80 dBµ ~ 100 dBµ at
14.200 MHz.
Adjust T3034 on the MAIN Unit for minimum
deflection on the RF millivoltmeter.
Disconnect the RF millivoltmeter from TP3037.
IF Trap (Scope) Adjustment
Set the following controls as indicated:
[IPO] button: AMP2
[ATT] button: OFF
[R.FLT] button: AUTO
[AGC] button: AUTO
[RF GAIN] knob: Fully clockwise
[VRF] button: THRU
Set the Main Band (VFO-A) frequency to 40.455
MHz in the CW mode.
Disconnect the coaxial cable from J3015 on the
RX-1 Unit, then connect the RF millivoltmeter to
J3015.
Connect the RF Signal Generator to the “ANT 1”
jack, then set the output level to 100 dBµ ~ 130
dBµ at 40.455 MHz.
Adjust T3003 on the MAIN Unit for maximum
deflection on the RF millivoltmeter.
Disconnect the RF millivoltmeter from J3015, then
re-connect the coaxial cable to J3015.
