The RTL-SDR Blog V3 is a low-cost software-defined radio (SDR) USB dongle bundled with a multipurpose VHF/UHF dipole antenna kit. It receives radio signals across a wide frequency range — from 500 kHz to 1,766 MHz — and processes them in software on your computer, making it an accessible entry point into SDR experimentation.

The V3 dongle features a temperature-compensated oscillator (TCXO) for frequency stability, a 4.5 V bias tee for powering active antennas, and an aluminium case for passive cooling. HF direct sampling mode extends reception down to 500 kHz without an upconverter.

Key Features

  • <1 PPM TCXO – Stable frequency reference without drift
  • 500 kHz – 1,766 MHz Range – Wide coverage including HF via direct sampling
  • 4.5 V Bias Tee – USB-powered for active antennas and LNAs
  • HF Direct Sampling – Receive 500 kHz – 24 MHz without an upconverter
  • Aluminium Case – Passive cooling and improved shielding
  • R820T2 Tuner – Popular, well-supported tuner IC
  • Dipole Antenna Kit Included – Two sets of telescoping antennas with mounts

Specifications

  • Tuner – R820T2
  • ADC – RTL2832U (8-bit)
  • Frequency Range – 500 kHz – 1,766 MHz (500 kHz – 24 MHz in direct sampling mode)
  • Bandwidth – Up to 2.4 MHz (stable)
  • Antenna PortSMA female
  • Input Impedance – 50 Ω
  • Current Draw – 270–280 mA
  • Compatibility – Windows (7+), Linux, macOS, Android, Raspberry Pi

Ideal For

  • Amateur radio monitoring and experimentation
  • Aircraft tracking (ADS-B)
  • Weather satellite reception
  • Learning about software-defined radio

Jargon buster

Plain-language definitions for the technical terms used above.

ADC
An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
ppm
ppm means parts per million, a common way to express very small gas concentrations in air. For CO₂ sensors, the ppm range tells you what levels the sensor can measure, such as normal indoor air through to poorly ventilated spaces.
SMA
A threaded coaxial connector commonly used for antennas. It matters because you need antennas with matching SMA connectors, or suitable adapters, for the LTE and GNSS antenna ports.
