Ats20 Firmware (2024)
Created by RaceNJason, this is a fork of Goshante's firmware that adds serial control via a UART/COM port . This is a game-changer for radio enthusiasts who want to integrate their ATS-20 into a home automation system, run it headlessly (without the screen), or control it from a computer. The caveat is that enabling this feature typically requires disabling RDS and battery monitoring due to memory constraints on the ATmega328P.
Select the appropriate Arduino board preset. Crucial: For the Go to product viewer dialog for this item.
This is widely considered the gold standard of ATS-20 firmware. Created by developer "Goshante," it is based on the foundational work of PU2CLR and draws inspiration from other projects. Many users consider it the best firmware for their needs.
Download the .ino or .hex file from a reputable source like GitHub (search for "SI4735-Arduino-Library-master" by PU2CLR).
The most significant development in the ATS20 ecosystem is the community-developed firmware, often referred to as the . Created by an independent developer, this firmware is widely regarded as the "must-have" upgrade for the ATS-20X (users must verify hardware compatibility before flashing). ats20 firmware

: The most stable and widely used codebase for Si473x radios.
Excellent low-light fonts, primary controls mapped to buttons rather than the encoder.
Here is what you stand to gain by flashing a custom or updated firmware: Created by RaceNJason, this is a fork of
Ensure you performed the EEPROM reset (holding the encoder while turning it on).
Choose a firmware version based on your needs. The ATS-20 typically comes with pre-installed.
Below is a drafted feature proposal for a , designed to enhance the DXing (long-distance) experience without overextending system resources. 📡 Feature: Signal Quality Sniffer (SQS)

This is another popular fork, ported to the PlatformIO environment, which is a more modern development ecosystem than the classic Arduino IDE.
The are incredibly popular among shortwave listeners (SWL) and amateur radio operators due to their affordability and versatile Si4732/Si4735 DSP chips. However, the stock firmware often limits the full hardware potential of these budget-friendly radios. Upgrading your ATS20 firmware unlocks essential features like SSB sync modes, interactive S-meters, precise tuning steps, and improved overall stability.
The ATS20 (often utilizing the SI4732 chip) is one of the most popular portable, budget-friendly shortwave radio receivers on the market. While the hardware offers incredible value out of the box, the stock firmware often leaves a lot to be desired in terms of user interface, tuning stability, and feature availability. Upgrading your ATS20 firmware unlocks the true potential of this powerful little device, transforming it from a basic receiver into a highly customizable DXing machine.
