: The heart of the radio is the Silicon Labs Si4735-D60 . This chip handles the majority of the signal processing for FM and AM (LW/MW/SW), including the selectable bandwidth filters (6K to 1K for AM and 4K to 500Hz for SSB).
: Sound quality (specifically bass response) can be improved by replacing the two electrolytic capacitors at the sound amplifier with higher-capacity versions. Antenna Upgrades
There are anecdotal reports of the D-808 getting hot during charging. A clear schematic would show the topology of the TP4056 (or clone) charging circuit, allowing users to verify the charge current resistor (Rprog) and safely install larger heatsinks or swap to higher-quality 18650 cells.
To improve the device's performance beyond factory standards, users often focus on the following areas: Audio Enhancement
: Highly regarded for DXing. It features a more robust front-end filtering section.
