Back in December 2021 I came across a Black Friday sale at Airspy. I saw the HF Discovery on sale for $125 so I bought one. I don't regret the decision.
It's a small SDR but slightly larger than the Airspy Mini. You can use the 9 volt battery for comparison. The SDR does not overload even when I aim directly at WAQY 102.1 or WMAS 94.7. I was also very impressed by Medium Wave reception, which is as good as, or maybe better than, the Elad FDM-S2. But what impressed me even more than the SDR itself, is the SDR# software that you use with it. The FM Canceller is actually a phaser, but using just one antenna. It really works (I haven't tried it on AM so I can't tell you about that.) It works great on FM. I have been using the HF Discovery over the winter and I've heard some new stations with it. I intend to keep using it. And, by the way, SDR# really helps the Airspy Mini. Note: You can only view a little over 700khz of spectrum max with the Discovery on the FM band. This fact could be a deal breaker for some people.
