Which (AM, FM, Shortwave, SSB, or Airband) do you listen to the most?
Tips to "Update" Your XHDATA D-808 Performance Without Software
One persistent topic of discussion is the . A user on SWLing Post pointed out that you can't simply scroll through stored memories with the tuning knob鈥攁 feature many other radios offer. This is likely a fundamental firmware design choice that hasn't been changed through revisions.
Updating the XHDATA D-808 firmware is a niche but useful process for enthusiasts wanting to resolve specific bugs. While it requires technical comfort with opening electronics and using serial adapters, following the correct steps carefully can breathe new life into an already excellent radio. If you鈥檙e not experiencing any issues, however, the old rule applies: xhdata d-808 firmware update
This is the biggest win. Early D-808s had terrible BFO (Beat Frequency Oscillator) drift. The 8832 firmware implements a temperature compensation algorithm. After a 10-minute warmup, SSB holds steady for 30+ minutes.
Because the D-808 relies on the Silicon Labs Si4735 DSP chip, some extreme hardware hackers completely replace or augment the internal microcontroller.
While you cannot update the software yourself, the manufacturer has released several hardware revisions over the years with internal "factory firmware" changes. How to Identify Your Version Which (AM, FM, Shortwave, SSB, or Airband) do
2. Changing the Temperature Display (Celsius vs. Fahrenheit) Turn the radio . Press and hold the 7 button to toggle between 掳C and 掳F . 3. Adjusting the FM Tuning Step (9 kHz vs. 10 kHz)
Many users power the radio via batteries and only connect GND, TXD, and RXD.
I will cite all the sources I found, including the radiojayallen article, the radiomuseum.org page, the tech360.pl review, and others. I'll now proceed to write the article. XHDATA D-808 is a model that has cemented itself as a favorite among radio enthusiasts and is often described as the "pocket rocket" of portable receivers. Since its release, this DSP-based, multi-band portable has garnered a strong following due to its excellent performance-to-price ratio and a comprehensive feature set that includes FM, AM, Shortwave, Longwave, SSB (Single Sideband), and the AIR band. Given the dynamic nature of digital technology, a common question among both new and seasoned owners is about the process of performing a "firmware update." This article explores everything you need to know about firmware updates for the XHDATA D-808, including the reality of the process, the concept of hardware revisions, and how to best manage your device. This is likely a fundamental firmware design choice
Since its release, the D-808 has seen several firmware iterations. Users have reported the following versions:
Locate the small, pin-hole sized on the back of the radio.
Notable changes included a shift in the circuit board design (from MV02 to MV04) and adjustments to how the battery level indicator and charging management behave鈥攅ffectively a "firmware correction" that was built into the new chips. 2023 "Modern" Version: The most significant "update" introduced a
