Di adiós a los puertos USB bloqueados. El pequeño NESDR Nano 3 es el SDR ideal para aplicaciones portátiles e integradas. Quad SDR en una Raspberry Pi? USB OTG? No es un problema para el NESDR Nano 3. El Nano 3 es de solo 17 mm x 8 mm x 20 mm pesa solo 15 g.
El Nano 3 está integrado en una carcasa de aluminio cepillado de alta calidad. Junto con las 2 almohadillas para orejas térmicas internas de silicona, esto garantiza que el calor se elimine del nivel de la placa y al exterior donde pertenece. La carcasa de aluminio garantiza que EMI se mantenga fuera de los circuitos SDR sensibles, y las emisiones de los circuitos digitales están contenidas dentro de la carcasa SDR. Este último es especialmente importante en entornos sensibles a EMI como aplicaciones automotrices y de vuelo.
Se incluye un conector SMA hembra articulado en ángulo recto para permitirle conectar tanto antenas SMA macho como MCX macho directamente a su SDR.
El NESDR Nano 3 contiene el mismo TCXO personalizado que incluimos en nuestra serie NESDR. Este TCXO de ruido de fase ultra bajo de 0,5 PPM, es, con mucho, el TCXO de más alto rendimiento disponible en cualquier SDR de bajo coste.
Estamos tan seguros de la fiabilidad y estabilidad de este SDR que ofrecemos una garantía completa de 2 años, la más larga de la industria.
Precaución: la carcasa se calentará. Esto es por diseño y no afectará al rendimiento de la SDR. Ten cuidado al tocar el SDR después de un uso prolongado. Un disipador de calor personalizado, que opcionalmente se puede fijar a cada lado del SDR para mejorar aún más la disipación del calor, está incluido con su compra.
Este RTL-SDR se basa en el CI de sintonizador R820T2 fabricado por Rafael Micro, lo que significa un rango de sintonización aproximado de 25MHz-1700MHz. También hay un IC RTL2832U a bordo para proporcionar demodulación básica y funcionalidad de interfaz USB.
Compatibilidad total con una amplia variedad de paquetes de software SDR populares, como Matlab, CubicSDR, HDSDR, SDR Touch, Planeplotter para Windows, Mac, Linux, Android y Raspberry Pi.

Works very well. For the software, I'm usingCubicSDR.Yes, it gets quite warm, but it does not seem to affect performance.

I am impressed by the tiny size and performance of this. I like the fact they designed it with the raspberry pi usb port dimensions in mind such that they fit perfectly even with 4 installed (not sure if this would be possible due to power requirements however) i know 2 is possible though. The heat sink shows that you get 2, which would have been nice because these puppies get HOT when in use. I came up with a way to drain even more heat though by using a solid aluminum case by FLIRC and slipping a piece of thermal pad/tape in between the FLIRC case and the radio's aluminum case where they meet. It's designed with very close tolerances so this works very well almost meant to be! you get a little bit more heat dissipation that way. Just search for FLIRC raspberry pi case on amazon and you'll find it. Anyway, this is Nooelecs best sdr design so far, imho. Some people did mention that the screws holding on the case can become stripped and loose easily, i haven't experienced this but it makes sense considering how little surface area there was for cutting threads and how soft aluminum is, so be careful with that or add a drop or two of thread locker, or super glue if you want and it should be alright. Mcx to sma adapter included, the mcx to type N I have snapped in though fits snugly and there is no wiggle. This is reassuring compared to some previous models that were sometimes loose.

I’m a fan of NooElec’s products. I own two NESDR SMArt receivers and a Ham it Up 1.3 with a Balun One Nine on its input. The price-to-performance ratio on their SDR modules—built in the US and Canada, no less—is excellent, as is their customer service. Emailed support queries are answered promptly, sometimes within minutes, by knowledgeable and friendly staff. When I had questions regarding the resonsance point of the fixed whips included with the SMArt bundle (I don’t own a UHF antenna analyzer), I received an honest “I don’t know, but I’ve escalated your question to an engineer”, followed up with an answer. When I needed an end panel for the aluminum Ham it Up enclosure, tapped for the optional noise source jack, they shipped it out promptly at no cost. I could go on.I recently acquired a handheld QRP HF transceiver with an IF tap, and I immediately knew the Nano 3 would make the perfect panadapter interface for my Netbook. My first impression upon unpacking the Nano 3 was, “man, this thing is tiny”. An 90° MCX to SMA adapter and optional heat sink are included in a small antistatic bag. Without the heat sink, the Nano 3 is designed to fit 2x2 in a Raspberry Pi’s USB ports.I need some time to decide if I feel like installing the heat sink myself, but I expect tuning to remain within the TXCO’s 0.5ppm spec, same as the SMArt, at least until the device is used outdoors in the heat. Out of the box, tuning is indeed as stable as advertised; my unit needed no compensation within in SDR#.This is a very affordable, very cool device.
