NooElec NESDR Nano 2+ Dual-Band ADS-B Bundle for Stratux, Avare, Foreflight, FlightAware - Includes 2 SDRs, 4 Antennas, 5 Adapters, Radio Frequency, 25MHz-1700MHz

I bought this kit to build a Stratux ADSB-In device for my vintage PA28. While priced a bit higher than I would have liked, I was pleasantly surprised when I had to contact support months after the Amazon return period had closed. One of the antennas turned out to be defective, so I emailed the vendor, and within a week Tasha had gotten me a replacement antenna to my door. The unit works well now, and despite the SDRs getting quite hot, the Swiss cheese style case I made is able to keep processor temperatures around 60°C without active cooling. I'm happy.

The 1090 chip never picked up any traffic despite switching USB ports, antenna cables, antennas, etc. Very little troubleshooting out there on the internet. Finally, I noticed that the LED inside under the black diode was not as bright as the 978 chip so ordered another set and long behold the led was brighter on this 1090 receiver and it worked perfectly.An item to note: Once you remove the plastic covers on the receivers to fit them into an RPi there is no easy way to tell the 978 from the 1090, except plugging them into a windows PC and looking at details under device manager for hardware id which reveals 1090 or 978.

I used this set to make a police scanner streamer. I use OP25 software to stream 2 P25 police scanner networks to Broadcastify. I did but different antennas that were better tuned, but the included antennas were close enough for initial setup.* Temperature sensors help with frequency offset* Small enough to fit side-by-side (must remove shell)I removed the shells, and cut off the infra-red sensor to put a heatsink on the module. I installed the Pi, radio modules, and antennas into this 3D printed case. I added 2 fans to keep everything cool, was pushing over 80° C (175° F) but with the fans & heatsinks it stays down around 40° C (105° F).This setup does the work of 2 $400 scanners, plus a PC for streaming. All for under $150 and significantly less power consumption.

They appear to work well. I've not gone all technical on them yet to see if the + has better tolerance really or if they are properly calibrated (they are sold as being for Stratux).My complaints are as follow:One came with a busted case. Not a big deal I guess as it let me see how to remove the case from the other one.They get VERY hot. That results in making the connectors and USB socket also get VERY hot. Like burn your finger style.So far they seem to work but just am amazed at the heat.The should mount some sort of mini aluminum or copper heat-sync on whatever part is getting so warm.The heat has me worried about them not lasting too long but time will tell.Overall this was the best value I found for stratux. You can get antennas and similar SDR for Stratux but they aren't using the better components that are said to help with drift in temperature swings so my thought is this is the better bundle and wasn't really any more price wise.

If you are looking for a starter set of SDRs (even if not interested in ADS-B) this kit with the Nano 2+ is the way to go. For just over the cost of 2 receivers you get the adapters, cabling, and antennas that are ok in VHF but good in UHF. You cannot go wrong with this.

This is a really good solution for a home made ADS-B receiver. The only minor problem is high power dissipation (and heat) due to the linear voltage regulators, so they need good air circulation.

These SDRs worked well. They run quite warm and the form factor limits your installation choices on the Raspberry Pi. I did have good results, I just found them awkward hanging out of the Raspberry Pi.

I only needed two parts out of this whole bunch, but it was not available.I wanted the two radio frequency dongles, but had to buy all of this.
