Looking for some schematics for these radios with the pll upd858.
All Am radios and dont need all just 1 of each if possible.

Im looking for the 36.380 tripler crystal circuit location in the radio a copy of that location would be great if possible.

I searched the internet and hard to find.
Looked on Cb tricks and nothing.

Yo do know that many of these radios you've mentioned are re-badged Unidens and use previous schematics of other versions of these radios?
Not always exactly the same, but in effect - similar.
Unless I am missing something here?
 
I have all the cobra XLR 858s schematics I just needed the 36.380 section just in case there is a difference in the listed radios. Seems cb tricks does not have these models. Was wondering if there is another place to find.

thanks tom
 
The 36.380 is a trippler circuit and the 36.380 divide by 3 = 12.126. So that is the actual frequency of the xtal even though its marked 36.380 most trippler xtals are marked this way. This is why I need some of the schematics to see the pll in these radios. Might of been wrong thinking it was the upd 858pll. Thanks for posting the schematic.

    Hello I have a old school 2950 receives great on all modes and transmits great on AM but no transmit on SSB. Does anyone have any idea?
