Ats20 Firmware Exclusive 🎉

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

exclusive community-driven firmware

The magic isn't in the hardware—it's in the firmware. While the stock firmware offers basic VFO (Variable Frequency Oscillator) functionality, the unlocks capabilities that even some $500 radios lack. ats20 firmware exclusive

  1. Identify your chip: Open the ATS20 back case. Check if you have the STM32F103C8 (Blue Pill) or the newer CKS32 clone. Exclusive firmware is usually for the genuine STM32.
  2. Backup the stock firmware. Use STM32CubeProgrammer to read the existing flash. Save it as stock_backup.bin. Do not skip this.
  3. Connect the pins: SWDIO to SWDIO, SWCLK to SWCLK. Do not plug in USB power. Use the programmer's 3.3V rail.
  4. Erase the chip: Full chip erase (not just mass erase) to remove bootloader conflicts.
  5. Load the exclusive .bin file: Set the start address to 0x8000000.
  6. Verify: After flashing, disconnect the ST-Link, power via USB, and hold the encoder button to reset.

ATS20 firmware exclusive

The ecosystem has transformed the affordable Si4732-based radio receiver from a basic entry-level device into a feature-rich tool for radio enthusiasts. While the stock firmware (typically PU2CLR V1.1.5) provides a solid foundation, exclusive community-developed updates like the ATS_EX by Goshante on GitHub unlock capabilities that were previously unavailable.
