25 WX NW ST Manual 3.3 6/15/99 1:10 PM Page 16 Operation Setting Squelch Operation Gate set to Desired Squelch Setting (DSS) Setting Squelch Squelch is the “control gate” for incoming signals. Gate closed 3 1 Full clockwise rotation closes the gate allowing only very strong signals to enter. 2 Full counterclockwise rotation opens the “gate” allowing all signals in. To achieve the Desired Squelch Setting (DSS), turn the Squelch control counterclockwise until you hear noise.
