Unlocks full access to LW (Long Wave), MW (Medium Wave/AM), SW (Short Wave), and FM bands.
"The radio went from being a toy for SWL listening to a useful receiver for ham operations." — KL7MJ, commenting on his ATS-20+ after a firmware update.
If turning the knob clockwise moves the frequency down instead of up, you need to invert the encoder pins in the software. Look for the encoder pin definitions (typically labeled ENCODER_PIN_A and ENCODER_PIN_B ) and swap their assigned numbers. 4. Severe Distortion on SSB
In many ways, the ATS20 is not a finished radio — it’s a . The community firmware turns it from a toy into a serious portable receiver, sometimes rivaling gear costing ten times more.
Once completed, disconnect the USB, turn the radio off, and then back on. ats20 firmware
Open your PC’s and look under Ports (COM & LPT) to find the assigned COM port number (e.g., COM3). Step 2: Configure XLoader Download and extract XLoader . Launch the XLoader.exe application.
The is more than just code—it’s the "soul" of the radio. By moving away from the stock software, you turn a $40 gadget into a surprisingly capable receiver that rivals much more expensive units in the amateur radio world.
This is often caused by selecting the wrong board type (Uno vs. Nano) in the programming software. Re-flash with the correct setting.

Clone or download the desired ATS20-compatible repository (such as the PU2CLR SI4735 repository) from GitHub.
: Widely regarded as a premier enhancement suite. The Goshante ATS_EX GitHub delivers optimized control interfaces, eliminates interface lag, adds precise frequency steps, and provides an integrated, noise-free layout. Step-by-Step Installation Tutorial
, are remarkably popular SI4732-based all-band radio receivers, but out of the box, they often feel like they are just scratching the surface of their hardware. If you've been using the stock
The SSB patch file failed to load into the microcontroller's EEPROM/Flash memory due to space constraints. Look for the encoder pin definitions (typically labeled
radio and a to USB type-A cable (note: the port dedicated for data, usually marked "USB download," is not the same as the charging port).
: The baseline for most custom software versions. Ricardo's PU2CLR GitHub Repository supplies raw code and examples, optimizing basic chip behaviors and forming a stable development foundation.
