An airspy can digitize 12MHz of bandwidth at once. Even without a gpu you can spit out easily over a dozen digitally subtuned channels. The bandwidth for all that raw signal data going out would be the problem. Only one person can control where that 12MHz is centred, but people can pick where in it they want to listen just like they do with websdr now.

Even a $30 RTL-SDR dongle can record 2Mhz of bandwidth reliably. I've recorded hours of signals just in case it sometime later becomes interesting, and it all lives in a little corner of my hard drive.

Damn! Yes, you would need to have one user center the spectrum read and you can mux the output to users wanting specific bands but I had no idea an airspy had such a wide audio capture.

Edit: I looked it up. You are indeed correct. 10MSPS IQ output. 10Mhz panorama spectrum view. That’s ridiculous! I just bought one.

I think the boxy one, the r2 not the mini, had some hacky way to get 80msps but it didn't specify how that made it over usb or why that wasn't the normal operational mode.
