Every Icom streams its waveform differently: the IC-7851 controls a scope it
never streams, and a real IC-7760 stops answering CI-V altogether a few
frames in — taking CAT and the audio down with it, which is this week's whole
dropout saga. Chasing a per-model frame layout for a decoration is not worth
a console that drops the link; the radio's own scope is better anyway. The
backend scope plumbing stays (harmless while nothing enables it); the UI and
its enable path go.
