Ats20 Firmware Exclusive Here
The ATS_EX firmware by Goshante (v1.18) significantly upgrades ATS-20/ATS-20+ radios, providing improved signal metering, battery management, and an enhanced visual display. This third-party build resolves SSB noise issues and offers better tuning functionality over stock firmware through an Arduino Nano USB flash process. Detailed installation information and firmware files are available on GitHub . ATS_EX Firmware for ATS-20 DSP Receiver - GitHub
| Issue | Likely Cause | Exclusive Fix | | :--- | :--- | :--- | | | LCD driver mismatch (ILI9341 vs ST7735) | Recompile or find a build with "Auto-detect LCD" flag. | | Volume stuck at max | GPIO pin mapping changed | Open the case; temporary fix: remove R18 resistor. | | No SSB (silent) | BFO (Beat Frequency Oscillator) offset drifted | Use the hidden menu: Press Vol knob 2x, tune BFO to 1200 Hz. | | Encoder spins opposite | Phase A/B swapped | Exclusive builds usually allow "Encoder Reverse" in Config menu. |
One of the biggest complaints about the ATS20 is the backlight noise bleeding into the RF path. Exclusive firmware introduces and a "dark mode" where the screen turns completely off during low signal periods, reducing noise floor by up to 6dBm.
Most users use AVRDUDESS (for Windows) or the Arduino IDE to flash the .hex binary file. ats20 firmware exclusive
The printed on your receiver (e.g., ATS-20+, SI4732 standard, V1.15)?
To get the most out of your newly upgraded ATS20, you may want to explore matching antennas or specific band configurations. I can provide detailed guidance on these next steps.

The custom firmware often ensures the ATmega328P controller runs at its full clock speed for maximum responsiveness.
Includes a Mute button, display on/off toggle, and adjustable CPU Frequency to reduce internal interference and save power.
Set the Baud Rate (usually 115200 for Arduino Nano-based boards). Click . Using Arduino IDE (For Source Code): Open the .ino sketch file. ATS_EX Firmware for ATS-20 DSP Receiver - GitHub
Optimized code reduces the processing overhead on the internal Arduino/ATmega microcontroller. This results in snappier button responses, smoother encoder wheel scrolling, and a noticeable decrease in current draw, which extends the battery life of the portable unit.
