Nooelec NESDR Smart V5 R820T2 SDR key + TCXO + Box + SMA antenna (optional)

rating Read the 4 reviews
Average rating: 4.5/5 Number of reviews: 4

The key NESDR SMART v5 is the new and improved version of the famous USB RTL-SDR dongle with the RTL2832U chipset and the R820T2/R860tuner, to receive all frequencies without gaps from 100kHz to 1.75GHz with up to 3.2MHz instant bandwidth.

Improvements in the NESDR Smart 5 version:

  • TCXO 0.5ppm for improved stability and accuracy
  • RF voltage regulator and shielded inductor
  • Integratedradiator to cool the SDR key
  • SMA female antenna connector
  • Aluminium casing to protect the key from parasitic interference
  • R820T2/R860 tuner
  • Phase noise @1kHz offset: -138dBc/Hz (or better)
  • Phase noise @10kHz : -150dBc/Hz (or better)
  • Phase noise @100kHz : -152dBc/Hz (or better)

RF 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 extended to 100kHz.

RF reception below 25MHz is direct sampling and requires a suitable antenna. We recommend using the Balun 1:9 (One Nine) to make a dipole antenna or a long wire.

We always recommend using a converter such as the upconverter HF SDR Nano Ham It Up for a more satisfying HF experience and even better performance for frequencies from 0.1 to 65MHz.

Optional: Antenna pack with magnetic base and 2m RG58 cable with male SMA connector and 1 telescopic 75-1000MHz variable-frequency lead, 1 433MHz antenna lead (ISM band) and 1 fixed antenna lead for UHF frequency (GSM).

Supplied with : 1 Nooelec NESDR Smart V5 SDR dongle, without antenna or CD. With optional antenna pack, to be chosen below.

Other similar model if out of stock: V3 dongle.

Data sheet

The USB key NESDR SMART is equipped with a 0.5ppm TCXO, ensuring frequency stability whatever the environment and temperature. In the quest for the lowest possible frequency noise, the power supply has been redesigned with a high-quality RF voltage regulator with less than 10μVRMS noise, around 10 times lower than the standard RTL2832+R820T2.

The inductor in the power supply is shielded to block as much ambient interference and noise as possible. The case also provides additional protection against interference.

A suitable heat sink has been added to dissipate heat away from the printed circuit board.Power consumption has been reduced by an average of 10mA, which means less heat is generated. Lhe result is an operating temperature well below the usual level, with improved stability and sensitivity.

With a SDR software for Windows linux or Mac, associated to other third-party software for decoding, this dongle can be used, for example, to decode a video signal.

Can be used, for example, to receive AM, FM, short-wave, ham radio, CB, ACARS (air-to-ground communications), ADS-B (aircraft tracking), AIS (ship tracking), POCSAG (pagers), NOAA and GOES weather satellites (weather images), weather balloons, radiosondes, DAB radio, DVB-T video, Inmarsat, Iridium, and much more!

What are the key differences between v4 and v5?

  • The HF frequency bands (0.1 to 25 MHz) are now available natively by direct sampling (Q branch) without any hardware or software modifications.
  • The reception range has been extended to 100 kHz, so that the frequency coverage of the NESDR Smart V5 key now extends from 0.1 MHz to 1750 MHz
  • Improved SNR and noise floor at VHF and UHF
  • Reduced spurs and visible harmonics in the spectrum
  • Compared with RTL-SDR v3, HF SNR is improved by up to 15 dB, VHF & UHF SNR is improved by up to 6 dB and tuning accuracy is improved by an average of 4x.

How do I know if I have an SMArt v5?

The NESDR SMArt v5 was officially launched in 2022 and you may already have a V5 in your hands.

You can check that you have a v5 by looking at the underside of the SDR key and looking for the v5 logo. If you don't see a logo, you have a version between v1 and v4.

Bon matériel

Il faut cependant une bonne antenne bien dégagée quand il n'est pas possible d'en installer je pense que l'antenne télescopique intérieure n'est pas suffisante quand on est situé en campagne .

très bon produit

Le ppm testé avec kalibrate-rtl est conforme à la description. Plus cher mais bien plus précis que tous les modèles vendus aux alentours de 20€ dans d'autres boutiques.
