This manual summarizes the public firmware documentation: supported ATS25 models, first boot, web installation, main screen, digital modes, EiBi database, activation, and common troubleshooting.
GOLDENRADIO targets ATS25-class receivers based on ESP32 and SI473x hardware. Verified targets currently include ATS25X2 and ATS25 MAX Decoder II; other ATS25 variants depend on the real RF front-end, LNA, HIZ, GPIO switching, display, and audio path.
After installation the radio opens with GOLDENRADIO setup. Choose the firmware language on first boot, then use the full trial mode before permanent activation. Activation removes the reminder screen and creates the permanent key for the displayed Program ID.
The recommended update path is the browser web installer. Use Chrome or Edge, a data-capable USB cable, and the correct CP210x or CH340/CH341 driver if your computer does not show a serial port.
The main screen is the control center: mode, bandwidth, tuning step, UTC time, frequency, band position, signal panel, spectrum/waterfall, volume, battery, and touch controls are visible in one workflow.
GOLDENRADIO adds listening workflows for FT8, FT2, CW and RTTY, with spectrum support and a practical EiBi database flow for shortwave station identification.
Most installation problems come from USB drivers, charge-only cables, busy serial ports, touchscreen calibration, or model-specific hardware differences.
