Since there is no downloadable software update, XHDATA has instead released several hardware revisions to address known issues: Original Version: Characterized by a white/blue display backlight charging port. 2021 Update: Introduced a warm orange/amber backlight for better nighttime visibility. Recent Revision (2024): Most new units now feature a USB-C port
Historically, XHDATA has not released official firmware updates, binaries, or "hacked" firmware updates that can be loaded by the end-user via USB. The firmware is flashed onto the internal microcontroller at the factory. 1. How to Check Your Current Firmware Version xhdata d-808 firmware update
For advanced hobbyists who want a truly updateable radio, the radio community frequently uses the same Si4735 chip found inside the D-808 in DIY projects. By pairing a raw Si4735 chip with an Arduino or ESP32 microcontroller, developers load custom "patches" (such as third-party SSB patches) via software. This requires building an entirely new radio project from scratch, but it allows for total firmware control. Summary of Best Practices How-To / Reality Impossible. The USB port is for charging only. Check Version Turn radio off →right arrow Hold AM/BW button for 3 seconds. Fix SSB Chuffing Cannot be fixed; it is an inherent DSP chip behavior. Boost Performance Use the 3.5mm external jack with a wire or loop antenna. Since there is no downloadable software update, XHDATA
Replace the stock battery with a high-capacity, protected 18650 cell from a reputable brand to extend runtime and stabilize voltage during high-volume SSB use. The firmware is flashed onto the internal microcontroller
has earned a reputation as a high-performing, budget-friendly portable radio for enthusiasts of AM, FM, Shortwave (SSB), and Air Band reception
Featured on the official XHDATA website , this version has a USB-C port and revised audio components.
