Squelch
This control is used to cut off or eliminate receiver background noise in the absence
of an incoming signal. Adjust until the receiver noise disappears. This will require the
incoming signal to be slightly stronger than average receiver noise. Further clockwise
rotation will increase the threshold level which a signal must overcome in order to be
heard. Only strong signals will be heard at a maximum clockwise setting.
Squelch is the “control gate” for incoming signals.
To squelch your radio:
1.
Full clockwise rotation closes the gate,
allowing only ver
y strong signals to enter.
2. Full counterclockwise rotation opens
the “gate,” allowing all signals in.
3. To achieve the Desired Squelch Setting (DSS),
turn the Squelch control counterclockwise until
you hear noise. Now turn the control clockwise
just until the noise stops. This is the DSS setting.
RF Gain
This control is used to adjust receiver sensitivity
. Maximum sensitivity allows
weak signals to be received. However, very strong signals (such as from a nearby
transmitter) can cause distortion at that setting. Adjust until the distortion disappears.
Reducing the receiver’s RF Gain eliminates distortion from very strong incoming signals.
To set RF Gain:
1.
Full counterclockwise rotation minimizes
gain for maximum distortion control.
2. To achieve the desired level of distortion control,
turn the RF Gain knob counterclockwise until
the distortion is eliminated.
3. After moving away from the strong signal,
turn the RF Gain knob fully clockwise to
receive all possible signals.
