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.\n\nThe 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.\n\nKey Features\n\n\n<1 PPM TCXO – Stable frequency reference without drift\n\n500 kHz – 1,766 MHz Range – Wide coverage including HF via direct sampling\n\n4.5 V Bias Tee – USB-powered for active antennas and LNAs\n\nHF Direct Sampling – Receive 500 kHz – 24 MHz without an upconverter\n\nAluminium Case – Passive cooling and improved shielding\n\nR820T2 Tuner – Popular, well-supported tuner IC\n\nDipole Antenna Kit Included – Two sets of telescoping antennas with mounts\n\n\nSpecifications\n\n\nTuner – R820T2\n\nADC – RTL2832U (8-bit)\n\nFrequency Range – 500 kHz – 1,766 MHz (500 kHz – 24 MHz in direct sampling mode)\n\nBandwidth – Up to 2.4 MHz (stable)\n\nAntenna Port – SMA female\n\nInput Impedance – 50 Ω\n\nCurrent Draw – 270–280 mA\n\nCompatibility – Windows (7+), Linux, macOS, Android, Raspberry Pi\n\n\nIdeal For\n\nAmateur radio monitoring and experimentation\nAircraft tracking (ADS-B)\nWeather satellite reception\nLearning about software-defined radio\n\n\nResources\n\nDatasheet (PDF)\n\n\nPackage Contents\n\n1× RTL-SDR Blog V3 USB dongle\n2× Telescoping VHF/UHF antennas (23 cm – 1 m)\n2× Telescoping antennas (5 cm – 13 cm)\n1× Dipole antenna base with 60 cm RG174 cable\n1× 3 m RG174 extension cable\n1× Flexible tripod mount\n1× Suction cup mount\n","vendor":"SparkFun","product_type":"","in_stock":false,"options":[],"variants":[{"id":1398,"title":"Default Title","sku":"SF-WRL-22957","price":180.0,"compare_at_price":220.0,"on_sale":true,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
