Raddy Mini Radio All-Band DSP Receiver, FM/AM/SSB

The Raddy Mini Radio is a pocket-sized all-band DSP receiver with Si4732 chip that delivers FM/AM/SW/MW/LW/VHF/CB coverage, SSB support, and firmware upgrades for long-term use.

Compact but capable, the Raddy Mini combines a high-sensitivity Si4732-based front end, an ESP32 controller, and digital signal processing to bring broad-spectrum listening into a pocketable tuner. Whether you want clear FM broadcasts, shortwave DXing, or single-sideband reception of amateur bands, this unit balances portability, audio quality, and upgradeable firmware for hobbyists and travelers.

What bands and modes can this receiver pick up?

The Raddy Mini covers a wide range of frequencies: FM, AM, SW, MW, LW, VHF and CB, and supports professional LSB and USB (single-sideband) demodulation. Digital Signal Processing reduces noise and stabilizes reception across weak or crowded bands.

• FM stereo and analog AM/MW/LW reception
• Shortwave (SW) with SSB capability for LSB/USB signals
• VHF and Citizens Band (CB) monitoring
• DSP filtering for noise reduction and clearer audio

How does the Raddy Mini handle audio and signal clarity?

This model uses a Hi-Z input circuit and a dedicated headphone amplifier to preserve detail at low signal levels and deliver better dynamics through headphones or the built-in speaker. AGC and DSP routines work together to keep volume and tonal balance stable as conditions change.

• Hi-Z circuit improves weak-signal sensitivity
• Headphone amplifier for cleaner private listening
• Automatic Gain Control (AGC) smooths level changes
• 1.9" color screen shows signal strength and tuning info

Is the device portable and easy to update?

The Raddy Mini is intentionally pocket-sized and lightweight (about 4.2 oz), making it convenient for travel, fieldwork, and outdoor use. Firmware upgrades are supported via USB-C, and open-source friendly firmware paths let you add community-driven features over time.

• Compact dimensions fit pockets and small packs
• Telescopic and donut antenna options for flexible reception
• USB-C port for power and firmware updates
• Open-source compatibility for custom feature additions

What accessories and display info assist day-to-day use?

The radio includes both a telescopic whip antenna and a small donut receiver antenna so you can choose the best setup for home or travel. The color display gives real-time readouts—frequency, signal strength, battery state—so you always know what you’re listening to.

• Telescopic antenna for outdoor and long-range pickup
• Donut antenna for compact indoor use
• 1.9" color screen with frequency and meter readouts
• Rechargeable battery status shown on-screen

Who is this for? The Raddy Mini Radio is aimed at radio hobbyists, shortwave listeners, amateur operators, and travelers who want full-band capability without lugging a bulky rig. It’s also a practical choice for anyone who needs a versatile, upgradeable receiver for on-the-go monitoring—campers, DXers, and tech tinkerers who appreciate an open firmware path will get the most value from this pocket-sized DSP radio.
