Modc1884
The
Model
884
FM
Modulation
and
Stereo Monitor
contains
a
low
level
RF preselector,
FM
monitor, stereo
baseband
monitor,
and
a peak detector. Four major circuit boards per•
form
these
functions:
RF
Preselector A
1,
FM
Demodulator
A3,
FM
Stereo
A4,
and
Display
Driver
A6.
The
block
diagram,
Figure
6-1,
is
located
in
Section
6of
this
manual.
RF
input
from
either transmitter
or
antenna enters the
884
rear panel
and
is
routed
to
RF
Preselector A
1.
Here
the
signal
is
padded through
the
attenuated circuit to a balanced
mixer.
The
900
kHz
IF
signal
is
sent
to
a
low
pass
filter.
This
IF
is
then routed
to
the
Demodulator
Board
A3.
.
FM
Demodulator
A3
receives
the
900
kHz
IF,
demodulates
the
signal,
and
delivers a pulsed
output
that
is
filtered
and
amplified.
The resulting
signal
is
filtered
and
routed
to
the
FM
Stereo
Board.
On
A4
the
composite
signal
is
filtered
and
returned
to
A3
and
to
the
front
panel
monitors
and
test
outputs.
Separation adjust
is
also
performed
on
A4.
Positive
and
negative
modulation
are
used
to
drive
the
front
panel
PEAK
flashers
on
A6,
the
Display
Driver.
Each
modulation
peak
is
compared
in
a
peak
detector
to
a
voltage
ob-
tained
from
a
constant
current
source
by
means
of
resistances
selected
by
pushbutton
switches
on
the
··
PEAK
MODULATION
flashers.
The
pulse
outputs produced
by
the
peak
detectors
when
modulation
exceeds
user
preset values are
applied
to
the
front
panel LED
flashers,
which
light
for
approximately
2 seconds..
4.2
RF
Preselector
Al
(Figure
6-3)
The
RF
input
to
the
monitor
comes
from
the
sampling
point
of
the transmitter
as
a high;
level
signal
or
from
an
antenna. The
high
input
level
enters
the
884
through the rear panel
RF INPUT HI
LEVEL
(50
ohm)
connector
J7.
The
signal
is
fed
through the adjustable
at•
tenuator
HI
LEVEL
RF
INPUT
SET
R2
on
the rear
panel.
This
high
level
input
signal
is
adjusted
for
a
constant
level
and
goes
to
the
AM
NOISE
detector,
which
is
routed
to
the
front
panel
TOTAL
MODULATION/TEST
meter. The
high
level
also
lights
the
rear panel
HI
LEVEL RF
INPUT
SET
LED
(21)
when
the
~F
level
adjust
is
correct. The RF
signal
goes
to
the
ANTENNA
INPUT
jack
(24
),
4-1
www.SteamPoweredRadio.Com
Model
884
When
an
antenna
signal
is
fed
to
the
ANfENNA INPUT,
JS,
it
is
routed
to
Zl
and
mixed
with
the
frequency
synthesizer
L.O.
(local
oscillator)
and
becomes
a
10.7
MHz
IF. This IF
is
fed
to
linear
phase
filter
FLl
and
then the IF amplifier Ul.
At
Ul,
the
level
detectors
detect the antenna
level
as
the
de
component.
When
detected,
the
antenna level
is
fed
to
US,
the
mute
detector.
The
factory
sets
the
mute
level
for
40
µY RF input. When the mute
level
is
less
than
the
factory
-set
level,
US
shuts
off
the
demodulator. This level also goes
to
the
rear panel terminal strip,
TB
2.
The IF
from
Ul
is
also
fed
to
Tl,
the
IF transformer,
and
then
to
U17,
the
balanced
mixer.
The
10.7
MHz
signal
mixes
with
the second LO.,
10
MHz,
from
the
timebase
crystal
oscil-
lator. The
mixed
signal
goes
to
the
low
pass
filter
which
looks
for
the
700
kHz
second IF.
This
700
kHz
is
routed
to
the
Q7
and
Q8
switch
and
fed
to
A3,
the
FM
Demodulator Board.
The
10
MHz
timebase
is
crystal-controlled oscillator Yl
and
its
associated components. It
is
the
refere
nee
for
the
PLL
frequency
synthesizer
and
is
also
the
second
LO.
4.3
FM
Demodulator
A3
(Figure
6-5)
The
900
kHz
IF
signal
which
is
applied
to
the
FM
Demodulator
Board
A3
through a
relay
to
a pulse
counting
FM
demodulator circuit. The
limiting
amplifier, Ul,
is
driven into
saturation
to
provide
limiting
.
U2
is
a one-shot multivibrator
acting
as
a pulse averaging
dis-
criminator.
It
delivers
a
pulsed
output
whose
frequency
is
the
same
as
the IF but
with
a
fixed
pulse
width.
The
duty
cycle
in
the output pulse train
varies
with
the modulation
and
the
audio
is
recovered
by
passing
the discriminator output
through
a
low
pass
filter. Transis-
tors
Ql
thru
Q4
make
up
the
clamping circuit.
The
low
pass
filter
consists
of l.2
and
LJ
and
amplifier
U7.
This
ci
rcuit provides a
flat
response
to
100
kHz
and
linear phase
in
order
to
give
good
stereo measurements. The
fre•
quency
response
rolls
off
after
100
kHz
to
eliminate
any
resiual
900
kHz.
Amplifier
UlO
raises
the
audio
level
to
1
Vrms.
The monitor calibration
circuit
consists
of
U3
thru
U6.
The
358
kHz output
o(
the timebase
is
divided
down
to
4.48
kHz,
which
is
then
used
to
gate
the
200
kHz
on
and
off at a
4.48
kHz
rate. This simulates a
100%
modulated input. When
the
front
panel
METER
CAL
switch
is
depressed,
this
calibration
signal
is
fed
into limiting amplifier
Ul
and discriminator
U2
in
place of the
900
kHz
IF.
After passing through a
7.5
kHz
calibration
low
pass filter,
it
is
amplified
by
U8,
which
is
adjusted
by
CAL LEVEL ADJUST
R29
to
give
a
100%
reading
on
the
TOTAL MODULATION/fEST meter. The
signal
can
also
be
used
to
check meter
and
flasher calibration.
The
circuit
is
very
stable and
can
be
·
used
to
correct drifts
in
the
one-shot discriminator
U2
and
the meter amplifiers.
