SetScope(false) sent both 0x27 0x10 00 (scope DISPLAY off) and 0x27 0x11 00
(CI-V data output off), so quitting OpsLog blanked a local IC-7300's own scope
screen. Only the display-on (0x27 0x10 01) is now sent, and only on enable;
disable stops the CI-V stream alone and never touches the radio's display.
