IF Gain
r
Turn the transceiver off, then press and hold in the
FAST
and
LOCK buttons (near the main VFO knob), and turn the trans-
ceiver on again.
r
Connect the RF signal generator to the antenna jack, and inject
a +11 dBµ signal. Select
menu function 9-1 , and adjust the
main VFO knob for a 1-segment S-meter deflection.
S-meter Full Scale
r
Connect the RF signal generator to the antenna jack, and inject
a +100 dBµ signal.
r
Tune for peak indication on the S-meter. Now adjust
VR2002
for S9+60 dB on the S-meter.
Noise Blanker
r
Set menu function 2-8 to “ A15 ,” then press the NB switch on,
and connect the DC voltmeter to TP2001 .
r
Connect the RF signal generator to the antenna jack and inject
a +40 dBµ signal, then adjust
T2001
and
T2002
in succession
several times for minimum DC voltmeter indication.
r
Reduce the RF signal level to +20 dBµ, and confirm at least
2.8 V on the DC voltmeter.
IF Notch
r
Preset the
NOTCH
control to 12-o’clock, then inject a +30
dBµ signal at 14.2000 MHz to the antenna jack. Select USB ,
then tune the transceiver to 14.20150 MHz (so that a 1500 Hz
tone is heard).
r
Press the
NOTCH
button, then adjust
VR2005
and
L2004
for
minimum S-meter indication.
FM Squelch Threshold
r
With the FM mode selected, and no signal present, set the SQL
control to the 11-o’clock position, then adjust
VR2001
so that
the squelch just closes.
