While it cannot decode the raw digital packets due to CPU limitations, the exclusive "Scout" mode listens for the 1090MHz carrier bursts. It tracks the signal strength and timing, allowing the user to triangulate overhead aircraft using the doppler shift heard through the speaker. No other sub-$50 radio does this without external hardware.
: This indicates an EEPROM mismatch. Turn off the device, hold down the main rotary encoder button, and turn it back on to trigger a hard factory reset.
Because exclusive firmware increases the chip's internal gain thresholds, a strong local signal can occasionally overload the receiver. A simple manual attenuator prevents clipping. Conclusion
You tune to a ham radio RTTY signal (usually around 14.080 MHz or 21.080 MHz). The firmware shifts the audio internally, filters it to 170Hz shift, and prints the decoded text directly onto the OLED screen. No external phone, no PC, no audio cable. The ATS20 becomes a standalone digital mode station. This is unheard of at this price point.

Tired of the generic text layout? Premium community firmware redesigns the layout of the 0.96-inch OLED screen, offering larger frequency fonts, retro signal meters, and cleaner menu navigation. 3. EEPROM Memory Banks : This indicates an EEPROM mismatch
This is the crown jewel of exclusive ATS20 firmware. Using the onboard processor's spare cycles, advanced builds include a .
: Some developers have released updates like V3.0.7g or specific versions by creators like CT2JWF , which may prioritize button-based controls over the rotary encoder. Exclusive Feature Enhancements ATS-20 Si4732 receiver firmware update
What changed:
: Displays up to 16 characters of Radio Data System info (station names, song titles) with toggleable information lines. Advanced Settings & Customization Power & Signal Management : Includes settings for Soft Mute (SM) Automatic Volume Control (AVC) SSB Cutoff Filters (COF) to refine audio quality. Hardware Control : Users can adjust screen brightness and even the CPU frequency to reduce internal radio interference or save battery life. New Operation Modes : Adds a dedicated CW (Continuous Wave) mode for Morse code listening. Installation & Constraints Flash Memory Limit
The display layout is often updated to show crucial information more clearly, including: AGC on/off status. Stereo/Mono setting. Signal Strength Meter (often improved in accuracy). 5. Increased Band Presets
