    Schematics needed for these AM radio with upd 858

    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...
