Review on NooElec NESDR Nano 3: Premium Tiny RTL-SDR with Aluminum Enclosure, 0.5PPM 📻 TCXO, SMA & MCX Input, and Custom Heatsink. RTL2832U & R820T2-Based Software Defined Radio by Geoffrey Graham

I've had a lot of RTL-SDR dongles over the years and these tiny ones are by far the best. I can actually swap out the old ones for these - ceteris paribus - and see the difference in terms of ADS-B and 433MHz pins. Virtually no PPM drift. So not only are they smaller; They are better. nits are common; They get untouchably hot and have unwanted MCX connectors. MCX connectors are the only reason I'm giving 4 stars instead of 5. If you like MCX connectors then consider this product a Best in Class 5 Star. I had some crashes after the first work and NooElec was very helpful and provided parts. If you use an outdoor antenna, I recommend protecting your devices from RF interference. Even a bandpass filter is better than nothing.
