  • New Version Upgrade: This upgraded receiver is equipped with robust ESD protection at the antenna input and an optimized Hi‑Z circuit for greatly improved signal clarity and noise reduction. It adds PCB‑level IO11 routing, ATS fast tuning, custom CW/RTTY firmware support, and a design that completely eliminates standby power loss. The previous version 3 can be flashed with German firmware to support CW/RTTY decoding, yet it does not have the dedicated hardware pin or ATS fast tuning function
  • Built-in RTTY & CW Decoding: Designed for amateur radio operators and SWL enthusiasts, this full-band radio receiver decodes Morse (CW) and RTTY directly on the device—no laptop, sound card, or cables needed. The decoded text displays clearly on the 1.9" IPS screen, making it ideal for contests, DX, emergency monitoring, and radio education. Skip the complicated setup and focus on the signals you care about
  • High Sensitivity & Sound Quality: Powered by the ESP32 + Si4732 DSP chips, this pocket radio receiver boasts strong anti-interference performance with no obvious birdies or digital RFI. Equipped with a built-in Hi-Z circuit and headphone amplifier—further enhanced by our re-tuned Hi-Z circuit path and shielding upgrades—it delivers clearer sound, higher volume, a much lower noise floor, and superior decoding signal quality. Additionally, the adjustable BFO enables precise fine-tuning in LSB/USB modes, ensuring stable reception even when signal drift occurs
  • ATS Fast Tuning: Blaze through bands instantly for wide-range scanning (saves time on signal hunting) — yet retains the Hz-level fine-tuning precision of slow knob turns (critical for locking SSB nets). Perfect for travel, outdoor listening , or in-depth signal exploration
  • Feature-Packed Design: At just 3×1.4×0.8 inches, this si4732 mini radio is lightweight and perfect for fishing, park outings, car trips, and walks. Boasting a vibrant 1.9-inch adjustable-brightness IPS color screen for clear indoor/outdoor visibility, plus an 800mAh battery delivering 10 hours of non-stop listening, it’s a must-have for radio lovers who value portability and performance
