XMT-Standby Switch
....
Activates the automatic antenna relay
circu it, also suppl ies power to the receive
ampl ifier circu it.
Receive Amplifier ON-Off Switch
Activates the integrated
circuit receive amplifier.
NOTE: Receive amplifier will only operate when theXMT-Standby.
switch is in the XMT position and the REC AMP switch is ON.
RED Indicator Light
, Visual indication of applied
+12V DC power
Output Meter
Visual indication of relative
RF power output.
Tune Knob
Adjusts resonant frequency of amplifier.
Load Knob
Adjusts coupling of output circuit to antenna.
The ampl ifier can be mou nted either under the dash using the
bracket provided or in the trunk as desired.
When the unit is dash mounted, a fused primary connection to
the battery or fuse block must be provided.
If tru nk mounted, a remote switch must be used, and can be
purchased through your local dealer. Mount the remote switch on
the dash where it is convenient. Remote switch mounting must be
grounded to the vehicle chassis or the indicator
light will
be
inoperative.
Remember the front
panel
and remote switches
are series
connected.
The ampl ifier
wi II not operate
if either
switch
is
in the
OFF position.
Before
beginning
installation,
it is recommended
that the
positive
lead of the battery
be disconnected
to prevent
ac-
cidental
grounds and electrical
system
damage.
Connect the fuse hookup cable to the positive terminal of the
battery or fuse block. The other lead should run under the seats
and carpets in the protected location to the amplifier
primary
power connection.
A length of RG 58/U should be installed
between the transceiver and amplifier. Connect a nominal 50 ohm
antenna to the amplifier.
Connect the ground stud on the amplifier to the negative battery
connection.
Before applying power, make one final check on all wiring and
connections.
Before applying
any RF power to the Linear, pretune the tune
control
knob to the desired
frequency
at which you wish to
operate.
See illustration
on this
page.
For example,
if your desired
operating
frequency
is 28 MHz
then set the tune knob at midpoint
between 26 and 30 as
shown.

•
For operation
on the
50
to
54
MHz band set tune control
to
the
30
MHz position
as shown
above.
Then refer to the 50
to
54
MHz Operation.
It
is assumed that
the bi-Iateral amplifier
has been properly
installed as called for
above. Make sure that all the various
connections have been made.
The following
paragraphs are intended to provide the operator
with
the basic knowledge needed to operate the amplifier
at
maximum performance.
This amplifier
must be used with
a transmitter
or transceiv~
capable of at least one watt output, in the 25-54 MHz range.
First place the function
switch in the AM-FM position. Set the
tune control
in accordance with the warning onthis pageof the
manual. The load control
should be positioned
so that
the
capa'titor is fully
meshed, (dot on knob will then point to the
word "load" on the front panel).
Now push the ON-OFF switch to ON. The red visual indicator
light will light.
After
warm-up,
push the
XMT-Standby
to
XMT.
This will
energize the automatic
antenna
relay
control
circuitry,
and
provide power for the integrated circuit receive amplifier.
Apply
drive
power
by
keying
the
exciter
(transceiver)
microphone and quickly
adjust the tune control
for maximum
reading
on
the
output
meter.
Remove drive
power
after
adjustment.
Do not apply drive power for more than five seconds
without
adjusting
the tune control or damage to the tubes can result.
Reapply drive power and advance (clockwise) the load contr~
note the increase in reading of the output meter. Adjust the
hi
control for maximum reading of the output meter. Now go bacR--
to the tune control and reset for maximum output. Remove drive
power.
