Beside the rig and amplifier chips, before ON AIR, because it is the same kind
of fact they report: a link that is either up or it is not. Clicking it opens
the settings that control it, like the amplifier chips do.
Shown ONLY while the opening watch is on. A permanently grey chip for a feature
nobody enabled is clutter, and the bar is 28 px tall — every chip in it has to
earn its width.
Green once decodes are arriving, amber while connected but silent: those are
different states and an operator wondering why no opening has been announced
needs to tell them apart. The count itself is in the tooltip, not on the chip —
it moves several times a second on an open band, and a number flickering in the
corner of the eye is a distraction rather than information.
