Field Expedient SDR: Introduction to Software Defined Radio (black and white version)

  • ...ges), 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, a magnetic antenna base with a 2m (6.5′) RG-58 feed cable, and 3 different antenna masts for UHF and VHF operation, including a variable-frequency telescopic antenna.
  • Proudly built by Nooelec in the USA and Canada! Full 2-year product warranty and product support through our support porta....
