Why we love it
  • Ultra-low noise enhances reception.
  • Unmatched accuracy surpasses competitors.
  • Easy setup, no extra purchases.
Main Highlights
  • An ultra-low noise software defined radio, capable of receiving nearly ANY RF signal from approximately 25MHz-1700MHz. Includes SDR, high-quality antenna base, and 3 antenna masts to get you started right away without any further purchases!
  • Unmatched price & performance--redesigned PCB reduces noise by an average of a full 3dB! Includes all the same fantastic features as the rest of the NESDR SMArt series, including an ultra-low phase noise TCXO, with a guaranteed <0.5PPM tolerance out-of-the-box. This is at least 4x more accurate than units advertised as containing 1PPM TCXOs, which have up to a +/- 2PPM initial offset
  • Same form factor as the other devices in our NESDR SMArt series, which means no USB occlusion issues--run devices side-by-side without messy extension cables or adapters, even on embedded devices like the Raspberry Pi!
  • Always-on, 4.5V bias-tee with independent ultra-low-noise power supply and 250mA power capability allows you to power nearly any active antenna circuitry without messing around with drivers or software
  • Designed and manufactured by Nooelec in North America. Impeccable quality and full 2-year warranty!

Why we love it
  • Wide compatibility with devices.
  • Enhanced signal noise reduction.
  • Extensive frequency coverage range.
Main Highlights
  • Turn your computer, phone or tablet into a radio scanner/ham radio receiver that can receive nearly all RF signals! Compatible with Windows, Mac OS, Linux, and Android
  • NESDR SMArt RTL-SDR v5 can be used for the reception of broadcast AM radio, broadcast FM radio, shortwave radio, CB radio, public security radio, trunked radio, air traffic control, ACARS (plane-ground communications), ADS-B (plane tracking), AIS (ship tracking), POCSAG (pagers), NOAA and GOES weather satellites (weather images), weather balloons, radiosondes, DAB radio, DVB-T video, Inmarsat, Iridium, and so much more!
  • The best-performing low-cost RTL-SDR available anywhere! Compared with RTL-SDR v3, HF SNR is improved by up to 15dB, VHF & UHF SNR is improved by up to 6dB, tuning accuracy is improved by an average of 4x, and the frequency range is expanded all the way down to 100kHz
  • v5 has a frequency capability of 100kHz to 1.75GHz and up to 3.2MHz of instantaneous bandwidth. HF reception below 25MHz is accomplished with direct sampling and requires a suitable antenna. We recommend using a Balun One Nine to make a DIY long wire or dipole antenna (sold separately, product ID B08HGSYB7R or B00R09WHT6)
  • Though the direct sampling implementation of NESDR SMArt v5 is much better than any other RTL-SDR, we still recommend using an upconverter like the Ham It Up for a more fulfilling HF experience (sold separately, product ID B076CYK8XZ)
  • Your purchase includes a NESDR SMArt v5 RTL-SDR. For a version which includes an antenna set, see product ID B01GDN1T4S
  • Proudly built by Nooelec in the USA and Canada! Full 2-year product warranty and product support through our support portal at https//support.nooelec.com
  • Full datasheet available: https://www.nooelec.com/datasheets/100701
