Expert hobbyists have developed "supercharged" versions by installing high-performance 7.5-inch (19cm) external loopstick antennas to drastically improve AM (Medium Wave) and Longwave sensitivity. Antenna Matching: Note: The Si4735 datasheet is public, but the

The XHData D808 schematic can be divided into several key stages: Note: The Si4735 datasheet is public

Recent teardowns have revealed significant changes between the "Original" (pre-2021) and "New" versions of the D-808.
