Silly SDR question for people.

At the moment [@vk4msl_sstv](https://mastodon.longlandclan.id.au/@vk4msl_sstv ) is down because I had to grab the radio I use for it to run a number of WICEN events… e.g. it was the base packet station radio at Kilkivan.

Using a full-blooded 100W rig like a FT-897D is a bit overkill too.

I have a headless Raspberry Pi 4 that I use for that SSTV bot. Headless meaning not only does it not have a monitor, it also doesn't run X or Wayland. That rules out anything GUI-based like GQRX, and no, I'm not going to run VNC/RDP/NX/Spice/<insert GUI remote desktop protocol here>.

Is there a SDR receiver that can drive a RTL-SDR dongle and decode SSB audio for piping to another application (either via Pipewire or TCP sockets) and be controlled via a CLI? I have an upverter to shift HF into VHF, I just need something to decode the I/Q data and control the VCO in the RTL-SDR.
