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. Press H to stop scanning. If needed, press < or > until you do not hear a signal. Á Turn until hiss heard. This lowers the "squelch gate," allowing all signals and noise to get through. Á Turn just until hiss stops. This raises the "squelch gate," allowing only strong signals to get through.

This prevents the alert from sounding unnecessarily due to farther, less important sources. 8
