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.
This thing and the new FreeDV audio codec BBFM will be a major breakthrough if they can be combined. The codec offers full 8kHz voice deep down into the noise floor without breaking the legacy channel width.
That would bring ham radio back to the top of the food chain in terms of digital radios.
