Why choose GOLDENRADIO
Not just an ATS25 update, but a complete evolution of your receiver. Features normally missing from low-cost portable receivers, integrated into GoldenRadio to make ATS25 much more complete and versatile.
First and only FT2 decoder on ESP32
GOLDENRADIO was the first firmware in the world for ESP32 to decode FT2 directly on the radio, and it remains the only official firmware to support it. FT2 uses 3.8 second T/R cycles for ultra-fast digital communications.
Country identification in FT8 and FT2
The only ESP32-based firmware that decodes the callsign prefix in FT8 or FT2 and instantly shows the country of origin of the signal. DX hunting has never been this immediate.
Spectrum & waterfall
Adaptive spectrum analyzer with waterfall lets you "see" weak signals your ears might miss. FT8 decoding over a full 3 kHz bandwidth — double what stock firmware offers.
Extended ATS25 compatibility
Tested on ATS25, ATS25+, X1, X2, max, max-Decoder, max-Decoder II, ATS25 PRO+ Air, ATS25-XF, ATS25AMP, ATS25 Ultra and variants with digital-modes modifications. ESP32 + SI473x hardware with ILI9341 and ST7789 DIY displays.
