indicate the center position.
5.8.
ADJUSTMENT OF
16
MHz GENERATOR.
5.8.1.
Enter fRx
: 11111
kHz to the KEYBOARD,
(press
1
and C simultaneously) and exe-
cute 5.2.
5.6.2.
Connect the diode probe to TP4.
5.8.3.
Adjust
LlOOl
to max. voltage (approx.
2V).
5.9.
ADJUSTMENT OF IF AMPLIFIER DETECTOR.
5.9.1.
Connect the signal generator to TP7
through a
10
nF capacitor, execute
5.2.2., 5.2.3.,
5.2.4., 5.2.5., 5.2.6.,
set the signal generator to fG
q
599 kHz
and VG z
10
mV.
5.9.2.
Set MODE SWITCH to A3J.
5.9.3.
Slowly
reduce
VG until noise starts to
dim the AF tone; then increase VG 20 dB.
5.9.4.
Connect voltmeter to HEADPHONES via a
screened cable, and adjust AF GAIN so
that the meter reads 0 dB in the 1V
AC range.
5.9.5.
Adjust L805 for max. meter reading and
at the same time keep this on 0 dB by
reducing AF GAIN.
5.9.6.
Set AGC SWITCH to OFF.
5.9.7.
Reduce RF GAIN until meter reading
again is 0 dB in the 1V range.
5.9.8.
Adjust L801 for max. meter reading and
at the same time keep this on 0 dB by
reducing RF GAIN.
5.10.
ADJUSTMENT OF IF FILTER.
5.10.1.
Execute 5.2. with fG = 600,O kHz,
VG
=
VG max.
&
fRx
= 11111
kHz.
5.10.2.
Connect the signal generator to TP7
through a
10
nF capacitor.
5.10.3.
Set the MODE SWITCH to A3H.
