Very cool, this was one of the projects I really wanted to build before I knew better. Trying to understand what was involved taught me so much. I couldn’t find what analog to digital converter and digital to analog converter this uses which would be interesting

I also think a wider bandwidth would be interesting if impractical. Something like recording everything happening on the 2 meter band would be impractical but very cool. I think

I have an RTL-SDR that can cover 3.2mhz -- and with sufficient storage IO could record just about the whole 2m band. I want to see if I could find or develop a SDR app that could visualize like sdrpp, or the other popular ones, but keep a 1-2 minute ring buffer of the data so I could jump back to previously spotted signals when watching a band.

Feels like you could put a PR in on this? https://github.com/SarahRoseLives/rtl_tcp_echo

Possibly -- I think the biggest work is more the UX of the functionality: all the controls and UI for scrubbing around the ring buffer, extending the buffer if you need to work a signal and don't want to lose data, jumping to current, etc.
