Setting the Squelch Threshold
Setting the Squelch is important for recep-
tion of signals you want to hear. There are ten
threshold levels, from 0, which allows all signals
to be received, to 9, which allows only the
strongest signal to be heard through the speaker.
The diagram in Figure 5 demonstrates how
setting the threshold level allows you to hear
only the signals you desire, while weaker,
unintelligible signals are not heard.
To set the Squelch threshold:
