Flipper Zero 3 in 1
Introduction
The ATS-Decoder SI4732 Full Band Radio is a compact yet powerful receiver designed for radio enthusiasts, engineers, and HAM developers who demand versatility, portability, and precision.
Full Band Reception & Touchscreen Operation
Powered by the advanced SI4732 chip, this pocket-sized radio supports a wide range of frequencies including FM (64–108MHz), MW, LW, SW (150kHz–30MHz), and SSB (LSB/USB). A 2.4-inch full-color touchscreen provides intuitive operation, allowing users to input frequencies directly, view RDS information, and adjust the backlight for optimal visibility in any environment.
Advanced DSP Decoding & Firmware Upgradeability
With support for multiple decoding functions such as CW, RTty, F4, and F8, and four distinct audio spectrum modes, the SI4732 ensures clear and accurate signal processing. The included H-RADIO 4.17 firmware enhances memory usage, improves frequency display accuracy, and delivers a smoother, faster user experience. Users can also perform online firmware upgrades, ensuring the device stays current with future improvements.
Versatile Controls & Rotary Encoder Lock
For seamless tuning and frequency adjustment, the radio incorporates a rotary encoder. A lock function prevents accidental changes, making it suitable for both stationary and field operation. It also supports broadcast search, digital frequency input, HAM fast channels, and adjustable AM/SSB bandwidth settings, giving users flexible control over their listening experience.
Long Battery Life & Modern Connectivity
Equipped with a 3.7V 4000mAh lithium battery, the SI4732 supports extended outdoor use. Its Type-C interface allows for fast charging up to 1.2A, while the built-in Bluetooth functionality offers quick access settings and real-time status indicators. Additionally, the device supports SNR calculation for SSB signals through spectral analysis, further enhancing operational accuracy.
Professional Audio & Interface Design
The radio delivers crisp, clear sound with its 1.5W audio output, complemented by a 3.5mm stereo headphone jack for private listening. For enhanced reception, it includes an FM antenna port, BNC interface, and external antenna connector. Its compact and lightweight design makes it a reliable companion for professionals and hobbyists alike, whether in the lab, in the field, or on the go.
