r
Connect the RF Signal Generator to ANT jack, and connect
the DC voltmeter to
TP1005
on the MAIN Unit.
r
Select the “
RX IF
” channel (10.15000 MHz, CW).
r
Inject a signal from the RF Signal Generator to 10.15100
MHz, then adjust the RF Signal Generator output level so
that the DC voltmeter reading is approximately 3 V.

RX Gain Alignment
r
Connect the RF Signal Generator to ANT jack, and connect
the DC voltmeter to
TP1005
on the MAIN Unit.
r
Select the “
RX IF
” channel (10.15000 MHz, CW), and recall
the [
RX GAIN
] parameter on the computer.
r
Inject a signal from the RF Signal Generator to 10.15100
MHz, then adjust the RF Signal Generator output level for 6
dBµ.
r
Press the [
F10
] key to activate the
SPOT-ADJ
mode, then
press the [
S
HIFT
] + [
p
]/[
q
] keys so that the difference of the
DC Voltmeter reading is 0.1 V ±0.05 V when the RF Signal
Generator on and off.
r
Press the [
F2
] key to save the alignment value to the trans-
ceiver.
Noise Blanker Alignment
r
Connect the RF Signal Generator to ANT jack, and connect
the DC voltmeter to
TP1004
on the MAIN Unit.
r
Select the “
RX IF
” channel (10.15000 MHz, CW).
r
Inject a signal from the RF Signal Generator to 10.15100
MHz, then adjust the RF Signal Generator output level so
that the DC voltmeter reading is approximately 3 V.
r
Adjust
T1013
and
T1014
for minimum indication on the
DC Voltmeter.
