Ats20 Firmware Jun 2026

For the first time, you have granular control over how the radio sounds, including a built-in adjustable AGC (Automatic Gain Control) and Noise Blanker . You can also adjust the De-Emphasis for FM stations, optimizing the sound quality for your region.

For casual broadcast listening (AM), the stock firmware is adequate. But for amateur radio operators hunting Morse code (CW) or voice (SSB), an upgrade is often necessary.

If you are searching for firmware today, you’ll likely encounter the . This version often features a larger battery, better filtering, and, crucially, firmware that supports a wider frequency range (sometimes down to 150kHz for Longwave).

The process of flashing (installing) new firmware is surprisingly straightforward. Many users were intimidated by the process, but community tools and guides have made it accessible. The example below uses , a simple graphical tool. ats20 firmware

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)

In many radio designs, the Beat Frequency Oscillator (BFO) used for SSB is a separate control that makes tuning a frustrating experience. Goshante has integrated the BFO into the main frequency control . This means you can tune SSB signals just as smoothly and naturally as AM or FM stations. The firmware includes fine-tuning steps as low as 1Hz, 10Hz, 25Hz, 50Hz, and 100Hz for precise adjustments.

Because the ATS20 uses a small 0.91 or 0.96-inch OLED screen, standard text can be incredibly difficult to read. Specific community firmware variants overhaul the display layout, featuring massive frequency numbers and clear, readable status icons for battery life and volume. Technical Prerequisites for Flashing For the first time, you have granular control

Advanced firmware adjusts the rotary encoder behavior, offering step sizes from 1 kHz up to 100 kHz, making fine-tuning a weak SSB signal much easier.

The firmware was compiled for a different display driver or I2C address (e.g., 0x3C vs 0x3D ).

The ATS-20+'s built-in features already provide a solid listening experience. Out of the box, it supports FM, AM (MW & SW), LW (Long Wave), and SSB (LSB & USB). It also includes a 0.96-inch OLED display, 22 pre-configured commercial and amateur radio bands, and audio bandwidth filters from 0.5 to 6 kHz. But for amateur radio operators hunting Morse code

. While functional, it is often viewed as basic, providing standard broadcast AM/FM and shortwave reception. The Game Changer (Goshante/ATS_EX):

The ATS20 is built on the Arduino hardware ecosystem, typically using an ATmega328P microcontroller connected to an SI4732 radio chip and an OLED display. Because it uses open-source architecture, independent developers have rewritten the code to fix factory bugs and add premium features.

What are you hoping to add? (e.g., better SSB tuning, a spectrum display, or a larger font?) What operating system are you using to flash the radio?

The ATS20 is a popular device used for various applications, and its firmware plays a crucial role in its functionality. Firmware is the software that controls the device's hardware components and provides the necessary instructions for its operation. In this content, we will explore the ATS20 firmware, its features, and the process of updating or modifying it.
