adjacent
signals.
The
PBT
has
no
effect
on
the
transmitter
frequency
or
bandwidth.
The
NOTCH
control
adjusts
the
center
frequency
of
the
audio
notch
across
the
pass-
band.
The
notch
depth
is
at
least
40
dB
and
will
reduce
carrier
interference
by
this
amount
or
more.
To
use
the
NOTCH,
rotate
the
control
slowly
until
the
unwanted
signal
is
reduced.
The
notch
circuit
is
effectively
removed
by
turning
the
control
fully
counter-clockwise.
3-4.8
MIC/RFPWR
The
RFPWR
control
varies
the
amount
of
power
output
for
all
modes.
This
allows
you
to
set
your
output
power
to
any
value
from
25
to
100
Watts.
The
MIC
control
varies
the
amount
of
audio
ap-
plied
to
the
transmit
balanced
modulator.
To
set
these
controls,
place
the
METER
switch
in
the
FWD
power
position
and
place
the
transceiver
in
transmit
using
the
TUNE
function.
Advance
the
RF
PWR
control
to
the
desired
power
level.
The
CW
level
is
now
set.
For
SSB
operation,
continue
by
placing
the
transceiver
in
either
the
USB
or
LSB
mode
and
while
speaking
into
the
microphone
in
a
nor-
mal
voice,
advance
the
MIC
control
until
the
ALC
LED
lights
on
voice
peaks.
NOTE:
The
ALC
LED
will
light
at
all
RF
PWR
settings
when
operating
in
CW
or
TUNE
modes.
Increasing the MIC setting over that
required to just light the ALC LED will not
result
in
any
appreciable
increase
in
power
out.
However,
overdrive
will
produce
SSB,
AFSK, or SSTV distortion products.
The PARAGON uses a “current-limit”
protection system where the drive level is
automatically
reduced
to
prevent
the
final
transistors from drawing more than 20 am-
peres.
If
full
power
output
сап
not
be
obtained,
it
is
an
indication
that
the
antenna
is
not
pre-
senting a 50 Q impedance. Refer to PARA-
GRAPH 4-1.4 for more information.
3-4.9
PROC
The
PROCess
switch
and
control
activates
the
speech
processor
and
de-
termines
the
processing
level.
The
processor
increases
the
average
speech
power
and
al-
lows
a
greater
range
of
voice
levels
to
attain
peak
ALC
level.
An
LED
below
the
switch
indicates
when
the
processor
has
been
se-
lected.
The processing level will affect the MIC
control
to
some
extent.
To
set
the
processor,
turn
it
off
and
adjust
the
RF
PWR
and
MIC
as
described above. Turn the PROCess switch on
and
advance
the
control
until
the
meter
needle
moves
into
the
center
of
the
black
band
(on
the
PROC
scale)
on
voice
peaks.
More
processing
is
available
by
further
clockwise
rotation
of
the
control,
but
the
MIC
control
must
be
re-
duced
to
keep
the
ALC
action
constant.
Severe distortion, objectionable back-
ground noise, and transmitted splatter will
occur
if
the
MIC
control
is
not
adjusted
so
that
the
ALC
LED
just
lights
on
voice
peaks.
The
processed audio may be monitored to prevent
this
distortion
by
using
the
MONITOR
control
on
the
rear
pancl.
The
use
of
headphones
is
recommended to prevent feedback from the
speaker. See PARAGRAPH 3-5.7.
3-4.10 RF/SQL The RF gain control varies
the gain ofthe I-F stages. The АССіз depend-
ent on the setting of this control and therefore
the S meteris calibrated only when the RF gain
control is fully clockwise.
The
SQL
control
sets
the
squelch
thresh-
old
level.
The
squelch
level
is
determined
by
Ше
AGC
circuits.
To
adjust
the
squelch,
rotate
the
control
clockwise
until
the
received
audio
becomes
quiet.
To
turn
the
squelch
function
off,
rotate
the
control
fully
counter-clockwise.
3-4.11
AGC
FAST
/
SLOW
&
ON/
OFF
These
switches
control
the
automatic
gain
control
(AGC)
system.
In
the
FAST
position,
the
recovery
time
of
the
AGC
system
is
ap-
proximately
.2
seconds
and
in
the
SLOW
position
approximately
2
seconds.
The ON/OFF switch defeats the AGC
