"Nine PBS" seems to be <https://www.ninepbs.org/>, A/K/A KETC, St. Louis, MO.
<https://en.wikipedia.org/wiki/KETC>
The upstream cited article which should be subbed in for this submission does clearly identify the station in the first line of its report: <https://current.org/2026/08/nine-pbs-sues-iron-mountain-over...>.
(I've submitted this to HN's mods via email. The original submission was to a very poor TomsHardware link.)
OT: The tendency of local broadcasters to fail to identify either on websites OR QUITE OFTEN ON BROADCASTS THEMSELVES even vaguely where they operate is ... a long-standing annoyance of mine. Sure, local audiences may know, but those passing through, or catching the signal at a distance, likely won't.
I've spent more than a few nights at higher elevations (campgrounds, highways) listening to clear channel stations reporting on weather and traffic "in the local area", sometimes for hours, without ever hearing what "the local area" is. That for signals travelling hundreds of km, and not infrequently multiple thousands of km.
(Don't get me started on entire countries where stations are identified simply by number, e.g., "Channel 4" in the UK.)
