Think of the squelch control as a
gate. If you turn Squelch fully
clockwise it raises the ‘Squelch
Gate’ so high that no signals get
through.

If you turn Squelch fully
counterclockwise it lowers the
‘Squelch Gate’ to the extent that
all signals get through - weak,
medium and strong signals and
noise.
To set the ‘Squelch Gate’ to the
desired level, turn the squelch knob
counterclockwise until you hear
noise. Then carefully turn the
Squelch knob clockwise until the
noise fades. Now only strong
signals get through.
