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		467.8500
1.	To set the squelch, press HOLD/RESUME to stop	467.8500
	scanning.
2.	Turn SQL fully counterclockwise until hiss heard.
	This lowers the “squelch gate,” allowing all signals and
	noise to get through.

3. Turn SQL fully clockwise just until hiss stops.

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