Ats20 Firmware Exclusive ((new)) -

The ATS-20 "Exclusive" (ATS_EX) firmware is an advanced, third-party upgrade for the ATS-20/ATS-20+ DSP receiver, primarily developed by Goshante. It is designed to replace the standard factory firmware (PU2CLR v1.1.5) with a more refined user interface and expanded features. Core Features of ATS_EX Firmware

Refined UI: Replaces original "stretched" fonts with a minimalistic, highly readable interface featuring a 7-segment frequency display.

Integrated Controls: BFO (Beat Frequency Oscillator) is integrated into the main frequency control, removing the need for a dedicated menu option during surfing.

Expanded SSB Support: Provides more precise tuning steps for Single Side Band (SSB) and adds a CW mode.

FM Enhancements: Extends the FM band (64–108 MHz) and adds dynamic RDS with 16-character display lines and station scanning.

Band Handling: Merges all SW bands into a single continuous range from 1710 to 30,000 KHz.

Digital Signal Visuals: Replaces poor RSSI displays with an optional S-meter scale. Hardware Compatibility & Versions

Before flashing, you must identify your device's internal revision by disassembling it:

Nano Revision: The Arduino is a separate board soldered onto the main PCB.

Uno Revision: All components, including the ATMega328 chip, are soldered directly to one main board.

Battery Metering: Standard firmware often looks at pin A2 for battery voltage. Some ATS-20+ units use pin A1, requiring either a physical "solder blob" bridge or a specific firmware version (e.g., ATS_EX_v1_18_A1.hex) to enable the battery meter without hardware mods. Installation Risks & Requirements Lets upgrade the ATS 20+

The ATS20 firmware exclusive 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. Top Exclusive Firmware Features

Upgrading to an exclusive firmware version often revamps the entire user experience with professional-grade tools:

Reworked Interface: Modern firmwares replace "stretched" fonts with minimalistic, high-readability layouts. Some versions even include a 7-segment frequency font inspired by high-end SWling equipment.

Integrated BFO Tuning: Unlike stock versions where the Beat Frequency Oscillator (BFO) is a separate, clunky menu option, exclusive firmware often merges it with the main frequency control. This allows for seamless, "liquid-smooth" tuning in SSB mode.

Expanded Band Coverage & Continuous Tuning: The firmware often treats the entire Shortwave (SW) spectrum (1710–30,000 KHz) as one continuous band, removing artificial sub-band limits while still allowing quick-switching between them.

Advanced Metering & RDS: Exclusive updates often replace basic RSSI bars with detailed S-meter scales and provide dynamic RDS for FM stations, displaying up to 16 characters of station info.

System Optimizations: Custom builds often increase the CPU frequency to improve encoder responsiveness and add battery level indicators (though some may require a minor hardware mod like a resistor or diode).

Forget the generic SI4732 builds you find everywhere. I finally got my hands on the ATS20 “exclusive” firmware (the one that’s supposedly optimized only for the ATS20 board, not generic SI4732 modules).

What changed:

Plus, the FM de-emphasis is finally correct for US/EU (selectable).

Heads-up: This is NOT the same as the “SI4732_ATS20” firmware from the public repos. The “exclusive” version has different pin mappings and AGC tuning. The ATS-20 "Exclusive" (ATS_EX) firmware is an advanced,

I’m unable to provide a full guide or copy of exclusive or proprietary ATS20 firmware (e.g., closed-source versions from vendors like ZL2CX, N7DDC, or custom-locked binaries).

However, I can give you a complete, actionable guide for working with open ATS20 firmware (mainly ATS-20 by SQ5RWU / IU3HXX) and explain how to identify/install exclusive versions if you already have the legal rights or files.

Final Note

If you received an exclusive .bin from a developer, follow their specific guide – many change pin mappings, display init sequences, or require a modified bootloader.
Without that, even correct flashing may fail.

What is "Exclusive" Firmware?

The term "exclusive" in the ATS-20 community usually refers to optimized, third-party firmware builds developed by enthusiasts (most notably by developers like Evan the Chinese or community contributions on GitHub). These builds are not official releases from the manufacturer but are tailored to fix bugs, improve the User Interface (UI), and add features that the stock firmware lacks.

Flashing Guide (ST-Link or Serial)

Hardware needed:

Steps (ST-Link):

  1. Connect SWDIO, SWCLK, GND, 3.3V (optional if ATS20 powered separately)
  2. Open STM32CubeProgrammer or STM32Flash
  3. Erase full chip (0x8000000 – size 64KB/128KB)
  4. Write exclusive .bin at address 0x8000000
  5. Reset device

Using serial bootloader:

  1. Connect USB-UART (TX→RX, RX→TX, GND)
  2. Hold Band+ → power on → release after "WAITING"
  3. Use STM32Flash or Flash Loader Demonstrator
  4. Upload .bin
