Hi. I do not like wires going to my phone, so i wrote LAN remote access to radio hardware. Just install windows version QuestaSDR, choose app type - "SDR Server". Choose hardware - sound card, rtlsdr dongle, airspy or other hardware, supported extio lib.
On another computer, or tablet, phone, choose "LAN remote". If server and client are in the same local network, server detect automatically.
So, for example, now we have 10 MHz bandwidth spectrum overview AirSpy on android phone! https://twitter.com/questasdr/status/989934809387536384 and the ability to view the spectrum in detail using new plugin - "IF Spectrum"
