• Functions for receive
<>Squelch
function
This function detects signals with voice components
and
squelches (mutes) unwanted signals such as
non
modulated beat signals. This provides quiet
stand
by.
When
you
need to receive weak signals, the squelch
should
be
turned OFF.
<>Noise blanker
The noise blanker function reduces pulse type noise
such
as that coming from engine ignitions.
The noise blanker may distort reception of strong
signals.
In
such cases, the noise blanker should
be
turned OFF.
<>
AGC
off
function
The receiver gain is automatically adjusted accord-
ing
to
received signal strength with the AGC (Auto-
matic Gain Control) function
to
prevent distortion
from strong signals and to obtain a constant output
level.
When
receiving weak signals with adjacent strong
signals or noise, the
AGC function may reduce the
sensitivity.
In
this situation, the AGC function
should
be
deactivated.
<>
RF gain setting
The receiver gain
can
be reduced with the
RF
gain
setting. This may
help to remove undesired weak
signals
while monitoring strong signals.
Usually, the AGC function reduces the
RF
gain
according
to
the receive signal strength and these
weak signals are removed. However, during periods
of
no
signals, these weak signals may not
be
heard.
In
such cases, the
RF
gain may
be
useful for setting
a minimum
level at which
to
hear signals.
<>
Clarity
control
Voice signals received from other stations may
be
difficult
to
receive. This may sometimes happen if a
station
is
transmitting slightly off frequency.
In
such
cases, compensate the receive frequency
only,
us-
ing
the [CLARITY] control.
