Signal Strength/R F Power Meter.
During
reception,
the
built-in
meter
provides
a relative
indication
of signal strength
in "S"
units
on the
upper
scale and thus
offers
basis
for
comparison
between
one
incoming
signal
and
another.
During
transmit,
this
will
provide
an
indication
of
antenna
RF
power on the lower scale.
As you speak, the pointer
should
"flicker"
slightly,
indicating
that
you are modulating
the
RF carrier.
AN L/NB
(noise blanker)
Switch.
The noise blanker
will
suppress much of the pulse-type
interference,
"ignition
noise,"
that
is often
a problem.
The depth of the blanking
and its relative effectiveness
are determined
by the signal strength of
the
stations
around
you.
This
is known
as the
"threshold
level"
If any station
is putting
out an S-9 or greater signal on any channel,
the effectiveness
of the blanker
will
be at least partially
blocked.
As
far as when to use the blanker is concerned, generally,
it is left on all
the time
when
you
are operating
mobile.
But when operating
as a
base station,
you may also find
it very helpful.
Don't
confuse
the
action
of
a noise blanker
with
a noise limiter.
Noise limiters
only
clip
off the peaks of the noise so that
it is not
as annoying.
This
is helpfu I, but
a noise blanker
is much
more
effective.
It actually
turns the receiver off
momentarily
so that
no
noise at all is heard.
When this
switch
is placed
in the AN L positIOn,
on Iy atmospheric
"type
noises are reduced.
But when
it is placed in NB position
both
the ANL
and NB circuits
are functioning.
CB Transmitter
Operation
IMPORTANT:
Do not
try
to transmit
without
a CB antenna con-
nected to the antenna connector
on the rear panel.
1.
Connect
the microphone
to the microphone
socket.
2.
Turn
channel selector to a desired channel.
3.
Depress the
push-to-talk
button
on the microphone.
Hold the
microphone
4 to 6 inches from
the mouth.
Speak at a normal
level.
During
periods
of transmission,
the
receiver
is silenced
and reception
is therefore
impossible.
I n the same way, your
signal can not be heard by another station when he is transmitting.
Each must take turns.
4.
To
receive, simply
release the
microphone
push-to-talk
button.
