Press 'Band+' to illuminate 'SW' and scroll through bands.
By applying the latest , you can maximize the capability of your radio, making it a powerful tool for shortwave listening (SWL) and ham radio exploration in 2026. Need Help? If you tell me what specific version of the
Various modified hex files circulate on amateur radio forums (such as RadioReceiver groups and CQHAM). These builds often come pre-compiled and feature highly customized UI graphics, retro signal meters, and expanded frequency ranges that bypass standard regulatory limits. Step-by-Step Firmware Flashing Guide
A short press of BAND- opens the settings menu, where you can navigate options using the encoder button. ats20 firmware
Never flash firmware if your battery is low, as a power failure during the process can "brick" the microcontroller. Conclusion
: The foundational community firmware that many others are built upon. It provides reliable SSB support and expanded band coverage. Key Feature Improvements Lets upgrade the ATS 20+

Ensure you performed the EEPROM reset (holding the encoder while turning it on).
This allows for better SSB demodulation, reducing "chipmunk voices" and making voice transmissions clear.

: Version v1.18 offers more features but is considered "advanced" and can be trickier to install.
However, the factory firmware is often just the starting point. To truly unlock the hardware’s potential—from improved audio fidelity to extended frequency ranges—you need to dive into the world of .
