RF AGC Adjustment
Set the following controls as indicated:
[ANT 1/2] button: ANT 1
[IPO] button: AMP1
[ATT] button: OFF
[R.FLT] button: AUTO
[AGC] button: AUTO
[RF GAIN] knob: Fully clockwise
[FLT] button: THRU
[MODE] button: CW
Connect the RF Signal Generator to the “ANT 1”
jack, and connect the Digital DC voltmeter (high-
Z) to J3016 pin 5 on the RX-1 Unit.
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.
Select the appropriate “Alignment Parameter”
using the (VFO-A)[SELECT] knob per the chart
below, then set the RF Signal Generator output
to each frequency & level, and adjust the (VFO-
B)[SELECT] knob for the corresponding DC volt-
meter reading at each frequency.
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
alignment mode.
IF Gain Adjustment
Set the following controls as indicated:
[IPO] button: AMP1
[ATT] button: OFF
[R.FLT] button: 3 kHz
[AGC] button: AUTO
[PITCH] knob: 700 Hz
[RF GAIN] knob: Fully clockwise
[FLT] button: THRU
[MODE] button: CW
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 1.900
MHz.
Set the Main Band (VFO-A) 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 Main [AF GAIN] knob so that the AC
millivoltmeter reading is “0 dB.”
Select the appropriate “Alignment Parameter”
using the (VFO-A)[SELECT] knob per the chart
below, then set the RF Signal Generator output
to each frequency & level, and adjust the (VFO-
B)[SELECT] knob for the corresponding AC
millivoltmeter reading at each frequency.
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
