NESDR Nano 2 Dual-Band ADS-B Bundle; Compatible with Stratux, Avare, Foreflight, FlightAware, and Other ADS-B Applications. 2 SDRs, 4 978MHz(UAT) & 1090MHz(ADSB) Antennas + Adapters and Cables

Works as expected. It is a niche product but it is a lot of fun. Skywave. Telive. Tetra. P25.

Bit over priced. And the usb x 2 do not fit into ras pi usb sockets. U need to remove the housings to make them fit...

produit très complet avec toutes les configurations matériel possible , livraison très rapide , je recommande ce vendeur !Félicitations ;-)

even with version 2..... version 3 would be fantastic......... still the seller is a pro ....the print on the antennas could be bolder but that is semantics

This SDR has been working very well for me. I have been using it with a variety of software packages including AirSpy gqrx. I have also created a couple of designs with Gnuradio. I have used the SDR with my desktop and a Raspberry Pi 3 with very good results. I originally bought this to make a dedicated ADS-B receiver, but it turned out to be too useful to use for just one thing.I have been using to study the design of software radios and digital filters. I also use it as a general purpose radio. I added a HamItUp converter also with excellent results. With it I can receive AM broadcast, HF, FM broadcast, air traffic, weather, and the various amateur radio bands of interest to me. When I want add features, I simply create a new design in Gnuradio or modify what I already have.I live in an area with several powerful broadcast transmitters within a mile or so. Overloading can be problem. I know others have had a problem with this. It’s important to control the gain. If the gain is too high, I sometimes don’t hear anything and the SDR appears to not work. This not a defect in the SDR. The solution is to use a gain that maximizes the signal quality. The optimum gain might be quite low. I sometimes turn the gain down to three or four dB with good results. I also use a sample rate of 2.4 MS/s even for narrowband applications. This causes the spurious signals to be farther apart and easier to filter out in software. Filters can be added between the antenna and the SDR, but this adds cost and I haven’t found it necessary.

Worked well

I'm still testing these out with a Stratux setup. I had been using the full size SDRs and they worked well but wouldn't fit the white Stratux case. Tried the more expensive Nano 3s but they seemed much less sensitive than the "full size" SDRs and ran extremely hot even with the case fan. Sensitivity on the Nano 2s seems good in both ADS-B use and with radio software on a home computer. Yes, cases must be removed to make them fit a Stratux setup and this version has a bright white LED that would be a distraction for night flying. It could be painted over or even removed if you're bold enough (or mount the unit where it won't bother your night vision).
