It does start over, but it doesn’t have to. It could keep the averaged data for the portion that used to be in the window and build up an average for the new portion. It would look odd for a moment, but operators would get used to it.

Yes, the programming is harder and I know the processor hits the wall at some point. But it would be worth it. With frequency bins, you could even save some averaging information on a scan change. Plus, as soon as Elecraft did this, every other bandscope would be obsolete.

My first rig was a borrowed IC-756. It was really nice, but losing the averaging on the band scope bugged the snot out of me every single time I turned the big knob.
