Xhdata D-808 Schematic -

The chip handles all AM, FM, and SSB demodulation digitally.

At the heart of the XHDATA D-808 is a Digital Signal Processing (DSP) architecture. Unlike traditional analog superheterodyne radios that rely heavily on mechanical intermediate frequency (IF) filters and complex alignment tuning, the D-808 digitizes RF signals early in the reception chain.
