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.

D 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.

D AGC OFF function

The receiver gain is automatically adjusted accord-
ing to the received signal strength with the AGC (Au-
tomatic 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.

D 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, vary the receive frequency only, using the
[CLARITY] control.
