RECEIVE AND TRANSMIT
■
Functions for receive
D
Squelch function
The squelch function detects signals with voice com-
ponents and squelches (mutes) unwanted signals
such as unmodulated beat signals. This provides
quiet standby.
When you need to receive weak signals, the squelch
should be turned off.
Push [SQL] to toggle the function on and off.
• “SQL” appears when the squelch function is turned on.

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 sig-
nals. In such cases, the noise blanker should be
turned off.
Push [NB] to toggle the function on and off.
• “NB” appears when the noise blanker function is turned
on.

AGC off function
The receiver gain is automatically adjusted according
to received signal strength with the AGC (Automatic
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.
Push [AGC] to toggle the function on and off.
• “

Clarity control
Voice signals received from other stations may be dif-
ficult to receive. This may sometimes happen if a sta-
tion is transmitting slightly off frequency. In such
cases, compensate the receive frequency only, using
the [CLARITY] control.
Adjust [CLARITY] to improve the audio signal.
