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.
