I'm eager to see if it is more stable than SoapySDR, OsmoSDP, CubicSDR. I find that all three tend to be fickle cross OS.

I use a HackRF One, and I can scan up to 5GHz, but it is painful: the bandwidth depends a lot on the hardware. You need ~$20k in radio hardware to effectively scan a usable part of that domain, and by that point it is better to just invest in a RTSA.

Or use better engineered hardware. HackRF One had some very weird hardware designs that don't perform well for the price.

Do you like any of the lower cost options, or do you think folks should be looking at, say, Ettus Research?

? HackRF is a $100 SDR with TX capability, there is nothing below its price with comparable capability.
