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.
