How Squelch Works
Think of “SQUELCH” as a gate. If
the gate is too low (squelch too
low), everything (all noise as well
as signals) gets through.
If the gate is set too high (squelch
too high), nothing gets through.
If the gate is set just right (squelch
set properly), just the desired
signals get through.
Setting the Squelch
No signal should be present when
setting Squelch.

➪
Turn until hiss heard.
This lowers the “squelch gate,”
allowing all signals and noise to get
through.
➪
Turn just until hiss stops.
This raises the “squelch gate,”
allowing only strong signals to get
through.
In the city, you may want to adjust Squelch even further counterclockwise to decrease the range of the Warning Alert.
This prevents the alert from sounding unnecessarily due to farther, less important sources.
