ATS-20 and its successor, the ATS-20+, are popular, low-cost, pocket-sized SDR receivers that have captured the attention of the radio enthusiast and hacker community. While functional out of the box, their true potential is unlocked by replacing the stock software with custom community-developed firmware. This article provides a detailed guide to the world of , covering the key projects, the installation process, and the advanced features they bring.
All components, including the ATMega328P chip, are soldered directly to the main board. Use "Arduino Uno (ATmega328P)" presets. ats20 firmware
The stock firmware is limited in features and can have quirks, such as audio pops or clicks, or less-than-ideal tuning mechanisms. This is where custom ATS20 firmware excels. The open-source nature of the Arduino platform allows developers to completely reimagine the radio's interface and functionality, turning a good receiver into an excellent one.
: Replaces basic signal layouts with a responsive S-meter to easily read incoming signal strength.
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.
Upgrading your ATS20 firmware is the single best modification you can make to this budget shortwave radio. It transforms a clunky, basic receiver into a highly capable, smooth-tuning tool for DXing, monitoring amateur bands, and listening to global broadcasts. Whether you choose to compile your own custom features via the Arduino IDE or quickly flash a community .hex file, the upgrade process breathe new life into your portable radio setup. : Tweak Soft Mute, De-Emphasis constants, Automatic Gain
The Ultimate Guide to ATS20 Firmware: Updates, Features, and Installation
However, the core principle remains the same: by controlling the microcontroller, you control the radio. This is where custom firmware comes in.
The ATS20 (often utilizing the SI4732 microchip) has become a staple for shortwave listening (SWL) enthusiasts, amateur radio operators, and casual radio hobbyists. This compact, budget-friendly All-Band Radio Receiver offers impressive coverage across FM, AM, MW, LW, and SSB (Single Sideband) modes. However, the hardware is only half the story. The true potential of this device is unlocked through its firmware.
Custom firmware introduces "speed-sensitive tuning." Turn the encoder slowly for 10 Hz steps (fine tuning for SSB) or spin it fast for 1 MHz jumps. This likely refers to firmware for the ATS-20 radio receiver

The most exciting feature added by firmware like PU2CLR's SSB library is a rudimentary . Using the radio’s internal ADC, the screen can display a live waterfall of signals up/down the band.
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. Why Upgrade Your ATS20 Firmware?
Ensure that you have applied the correct SI4732 SSB patch file if you are using an advanced firmware build. The radio requires a specific binary patch loaded into memory to process SSB signals correctly. Conclusion
