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

1. To set the squelch, press HOLD/RESUME to stop scanning.

If needed, adjust

VOL until you do not hear a signal (see

page 17).

2. Turn

SQL fully clockwise until hiss heard.

This lowers the “squelch gate,” allowing all signals and noise

to get through.

3. Turn

SQL fully counterclockwise just until hiss stops.

This raises the “squelch gate,” allowing only strong signals to

get through.

In the city, you may want to adjust the Squelch even further

counterclockwise to decrease the range of the Highway Warning

Alert signal.

This prevents the alert from sounding unnecessarily due to

farther, less important sources.
