For example, the -N 'LNA:15,MIX:15,IF:15' syntax was something I searched for and found in a RadioReference forum. One of my screenshots below shows "built-in source types:" with what looks like a list of things that can be entered with the --args command. But it doesn't list 'airspymini' as one of the options and I wonder if it should? I think if you just make up something bogus, it'll be ignored.

I tried re-booting and un-plugged both Airspys and plugged only 1 of 'em back in.

So I don't see anyone using this on Windows really contributing anything back to the community.
