ANTENNAS
Апу
antenna
presenting
50
to
75
Q
impedance
will
load
satisfactorily.
Random
length
and
balanced
antennas
will
require
an
antenna
tuner.
Most
popular
mobile
antennas
will
operate
at
their
resonant
fre-
quency
without
special
matching.
When
they
are
used
as
portable
antennas,
a
good
ground
system
or
Counterpoise
should
be
provided.
The
PARAGON
is
designed
for
use
with
an
unbalanced
feed
system.
Although
improper
antennas
will
not
damage
the
final
output
transistors,
it
is
sug-
gestedthat
an
SWR
of2
to
1
orless
be
achieved
for
maximum
performance.
In
cases
where
the
antenna
cannot
be
matched
to
a
better
SWR,
the
PARAGON
can
be
operated
at
re-
duced
input
power
by
adjusting
the
RF
PWR
control.
Be
sure
to
readjust
the
MIC
control
after
reducing
the
RF
PWR
level.

MICROPHONE
For
SSB
operation,
plug
a
low
impedance
dynamic,
or
electret
microphone
into
this
jack.
Amplified
micro-
phones
can
be
used
if
the
output
level
is
ad-
justed
to
а
low
enough
value
to
prevent
the
microphone
circuit
from
overloading.
High
impedance
mics
(above
25КО)
will
not
work.

KEY
For
СУУ
operation,
connect
a
straight
key,
bug,
or
electronic
keyer
to
this
jack.
When
using
electronic
keyers,
they
should
be
configured
for
positive
keying,
not
"grid
block"
or
negative.
If
configured
for
negative
keying,
no
damage
will
occur,
but
the
keying
circuit
will
not
operate.

GROUND
In
the
interest
of
personal
safety
and
to
reduce
the
possibility
of
stray
RF
pickup
on
interconnecting
cables
which
may
cause
parasitic
oscillations,
all
station
equip-
ment
should
be
well
grounded
to
earth.
It
is
also
important
to
strap
all
equipment
chassis
together
with
short,
heavy
leads.
The
strap
between
the
power
supply
and
the
transceiver
also
serves
to
reduce
the
voltage
drop
on
the
negative
lead
caused
by
wire
and
connector
resistance.
In
mobile
installations,
connect
a
ground
strap
between
the
rear
panel
ground
lug
and
the
automobile
chassis.

BATTERY
BACKUP
As
long
as
the
PARAGON
is
connected
to
a
source
of
13.8
VDC,
the
microprocessor
and
memory
RAM
circuits
will
retain
all
memories,
last
fre-
quency
used,
and
date
&
clock
information.
The
front
panel
POWER
switch
does
not
re-
move
power
to
the
logic
circuits.
To
prevent
loss
of
memory
during
power
failures
or
while
transporting
the
PARAGON,
a
backup
battery
(9
volt
alkaline
or
Ni-Cad)
can
be
installed
in
the
PARAGON.
Refer
to
PARAGRAPH

for

mation
on
removing
the
top
cover.
Located
in
the
center
of
the
chassis
is
the
battery
holder.
A
battery
clip
is
included
in
the
packing
kit
shipped
with
the
PARAGON.
With
the
POWER switch in the ON position, and the
PARAGON operating, install the battery in the
holder
and
plug
the
battery
cable
into
the
49V
connector
located
on
the
left
rear
corner
of
the
