Xhdata D-808 Schematic [hot] Guide

The heart of the D-808 is the DSP chip. This is the same chip found in the Tecsun PL-330 and PL-990. Luckily, Silicon Labs publishes the official datasheet and application notes for the Si4735 (easily found via PDF search). This datasheet acts as a pseudo-schematic for ~70% of the D-808's functionality, including:

The most prized document floating around the internet is a "reverse-engineered schematic" created by a collaborative effort of users. While it lacks the polish of an official engineering document, it reveals the radio's secrets: xhdata d-808 schematic
