This manual covers standard ATS-20 hardware revision v2.1 – v2.3. For firmware updates, schematics, and community support, visit: If you would like to explore deeper custom

Controlled via the menu or a direct shortcut, depending on the firmware version.

The ATS-20 is a popular, compact, software-defined radio (SDR) receiver celebrated for its wide frequency coverage, digital display, and portable design. However, like any feature-rich SDR, its true potential is unlocked only by understanding its controls and menus. This is where the becomes an essential tool.

Select the correct COM port and board layout (usually Arduino Pro Mini or Nano, depending on the internal clone board). Flash the compiled sketch to the radio. Troubleshooting Common Issues Robotic or Distorted SSB Voices Open the case to verify the processor model

What are you most interested in listening to (e.g., local FM, international shortwave, ham radio operators)?

Many ATS-20 radios ship with basic, unoptimized firmware. Upgrading to community-developed Arduino firmware completely transforms the user interface and performance. Benefits of Custom Firmware Smoother rotary encoder scanning. Additional frequency step options. Improved RSSI (signal strength) meters. Expanded frequency coverage unlocked by the SI4732 chip. Quick Upgrade Steps Connect the ATS-20 to your PC via a USB data cable.
