Uniden pc66xl

[Dorian]

Does anyone know the value of d-9, I'm guessing it's the diode in the modulation circuit? I want to restore this radio to original specs. Also need a readable schematic. Thx for your help. Dorian

this is the only schematic I have ever seen for one. Uniden stopped making any service manuals for their radios years ago. not sure just how accurate this one is.

Uniden stopped making any service manuals publicly available for their ̶R̶a̶d̶i̶o̶s̶ products years ago.

Fixed that for you.

But yeah the Cobra 25 LTD is close enough to a PC68 XL(don't know about ur 66) .
The part labels may be different, example TR43 in a Cobra may be Q43 (Q23 or w/e) in the Uniden PC68 XL.
