The driver for some airspy to download is indi-rtlsdr. I think you should build it from source since the debian packages are not ready yet.
There's the need for testers to work on the server/client configuration to connect to an rtl_tcp server.
I can now see how the 3rdparty drivers fit into the hierarchy. ( Specifically Github/indilib/indi-3rdparty)
I realised I needed to BUILD the driver on MY platform ..( a Raspberry Pi running Ubuntu MATE).
Couple of false starts with an incorrect path and missing Indilib-developer library..
But... pleased to say NOW up and running !.. Now for some system tests, and greater understanding of the parameters !
