The ATS_EX firmware by Goshante (v1.18) significantly upgrades ATS-20/ATS-20+ radios, providing improved signal metering, battery management, and an enhanced visual display. This third-party build resolves SSB noise issues and offers better tuning functionality over stock firmware through an Arduino Nano USB flash process. Detailed installation information and firmware files are available on GitHub . ATS_EX Firmware for ATS-20 DSP Receiver - GitHub
: The base for many versions (including factory V1.1.5), this library-based firmware supports a wide range of SI473X chips and is often used by developers to create custom variants.
: Considered a major "exclusive" upgrade, it features a completely reimagined, minimalistic interface that replaces the stock "stretched" fonts with a 7-segment style frequency display. It also integrates BFO (Beat Frequency Oscillator) directly into the main tuning process and adds an S-meter. radio receiver has garnered a cult following among
The stock signal meter is notoriously inaccurate. The new firmware update implements a calibrated Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR) readout in real-time. This allows you to precisely align external antennas and calculate propagation metrics. Dynamic Bandwidth Filtering
If the radio freezes on the splash screen, the firmware layout might conflict with your specific OLED screen driver (I2C address mismatch). Reflash a version optimized for SSD1306 screens.
At its core, the ATS-20 is a compact, battery-powered SDR (Software Defined Radio) receiver. It builds its impressive capabilities around the high-sensitivity ——a popular, high-performance integrated circuit also found in many commercial portable radios. This chip gives the ATS-20 excellent reception and the flexibility to be re-programmed through its firmware.
