I'm currently running Buster on a Pi 4 decoding a busy Smartnet system. Unfortunately, its CPU is about maxed out all the time according to htop. I'm not sure if the device is thermally throttled (although it's mounted in an active heatsink case,) or the processing of an mostly analog simulcast system is just too much work for the hardware (a similar setup runs much better on an old NUC.) The audio is several seconds behind a hardware radio sitting next to it, which is to be expected. The interesting thing is that digital tgs are more reliably reproduced than the analog tgs. In other words, many analog transmissions are simply missed. Anyway, I want to cut down on running processes as much as possible. I'm probably going to reflash the OS - but what OS to use?
