The github as well as the wiki seem to be entirely devoid of the "this program does X, Y and Z", and no, "explore the electromagnetic spectrum" does not cut it.
Thread hijack: I dream of a TUI SDR Linux app, so I can SSH into a box with an sdr, control it, and somehow get audio back, either through some streaming port or somehow over the SSH link itself. I've looked but failed to find it - is the cli version of this app what I'm looking for?
Bonus points for waterfall display nicely rendered
Possibly close to what you describe, gqrx (a GUI SDR Linux app) has a remote control protocol that can be typed by hand or scripted over telnet. And it has the option to stream the audio over UDP to a remote host.
For a demo of the remote control protocol, see this video: "Ham Radio - Network sockets and remote control of GQRX SDR with telnet and python"[1]
SDR Sharp has a good server implementation. It doesn't send the entire I/Q stream (which is 2 megabytes / second for each MSPS at 8 bit precision), but rather sends the FFT processed waterfall plus only whatever you are currently tuned to. Works really well even on weaker network links. If bandwidth is not a problem you can of course just stream the entire I/Q, SoapySDR has that option.
It's like a radio signal workstation, cribbing from the "digital audio workstation" term in the music world.
