         I have no reproducable schematic on the PRC-8. As far as I know the difference with the PCR-9 and PRC-10 is in the matching circuit to the whip antenna. Anyway it should have its own schematic, because my neat schematics refer only to to the PRC-9 and PRC-10.
The PRC8 omits C-12, an extra antenna-tuning varco, that is worm-geared connected to the reduction-gear of the 5-section tuning-varco in the PRC-9 and PRC-10. The difference can be seen in the attachments.
