An ultra-low noise software defined radio, capable of receiving nearly ANY RF signal from approximately 25MHz-1700MHz. Includes SDR only! For a full package with an antenna bundle, please see http://www.amazon.com/dp/B079C4S2BT | 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!
