[MENU+3+9] Squelch Level A
（
SQL A
）
The squelch circuit allows you to only hear desired
signals. If a strong enough signal is not present, the
squelch circuit is closed, and you will hear no
background noise. Higher levels of the Squelch level
setting require stronger signals to open the squelch
circuit. Set the squelch level to one appropriate to the
amount of RF noise in your environment. A squelch
setting that is too high may cause you to miss
receiving a weaker signal, while too low a setting may
cause you to hear more noise than you might want.
Set the Squelch Level of channel A using Menu 39.
There are nine levels of squelch setting; the default
level is 2.
