Nooelec HackRF One Software Defined Radio, ANT500 & SMA Adapter Bundle for HF, VHF & UHF. Includes SDR with 1MHz-6GHz Frequency Range & 20MHz Bandwidth, ANT-500, and 4 SMA Adapters

Excellent build quality. Needed adapters included, which is convenient. Intuitive controls via recommended software app make this SDR easy to use right out of the box. Love the 20 Mhz bandwidth which allows you to monitor several different frequencies simultaneously. Works surprisingly well on HF and does really well on trunking systems. While I initially thought this was pricey, after using it I was able to experience the value. It is compatible with many different antennas and SDR software packages so is very flexible. I also feel the sensitivity of the receiver is much better than other offerings. Very satisfied with my purchase.

This is a fantastic SDR for people who like to experiment. It has broad support across software-defined radio applications and can sample 20MHz of spectrum at once. I mainly bought this to use in an educational interactive demo to teach people the basics of RF communication and it worked great for that purpose. I've also used it for a fair amount of "normal" listening across HF, VHF, and UHF as well as decoding of various digital signals and it works really well for those applications as well, though it's definitely not the most cost effective option out there if you don't need the 20MHz bandwidth this unit offers.

Good for Layer 1 OSI shenanigans to show up your uncle who worked on the telemetry for the curiosity rover that went to mars, too bad we didn’t go deep enough to find cold Martians living off the secondary energy source: the center of mars is liquid hot magma, heat is energy, energy is life. The Martians are cold, won’t somebody warm them up? We are water based life forms in this star system if you want to generalize. Just ask the Plutonians if they’re ice based life forms and they’re inclined to say no.

Sorry I returned it to get the new hackrf pro. The adapters where nice.

I ended up getting this as a hobby device to learn about RF. It is a great and flexible tool, but I honestly regret not getting a less expensive option. It works well, but really ended up being a "jack-of-all, master of none" solution. It's definitely fun to play with lower frequency ranges, and I still use it to this day looking at 2.4Ghz ranges, but it has fairly limited bandwidth and is all but useless for wifi analysis anymore (short of just raw spectrum analysis). Great device that has started a legacy, but it's definitely past it's prime and, at this price, there are better options. Great learning tool though.

Cool, tricky to use and way too expensive. I haven't figured out how to turn on the bias-tee yet. Be prepared to do research and download random stuff you have to search for. My Eton Elite 750 (another radio that is a bit expensive) will pull in FM stations that the HackRF One can't on the same very nice outdoor antenna at a pretty good height, but it connects to a computer (and is dependent on a computer) and can pick up high frequencies from satellites so... in the end it will do what I want and more. I'm thinking the Eton was a better value. I'm only about 6 hours into it at this point but I wish it were less expensive and easier to use.

Works great!!! As soon as the pro version is available here Ill buy it too!!!

Haven't had any issues with it. Only occasionally use it, but its always worked. Great if you need to transmit and not overly expensive for what it is.
