How to clip and tune

why do you want to clip and tune a radio? Clipping the diode will make the radio modulate higher and unrestricted but if you take that radio and turn the power down to 2 watts give variable 4 a full turn to the right and open the modulation pot it will sound a whole lot better then if you clipped it. when you clip a radio you create a splash box that wipes out all channels lose by and the others will also be effected. the diode you want to clip is D-11. but I advise you not to.

Need to turn rf gain down inside uniden pc66xl c.b.

The radio should have a RF gain control on the front of it that should drop reception to almost nothing unless sitting side by side in very close quarters.

You could have the receiver detuned but that really makes no sense.
