@ David :
Perhaps this might not be too much into legal-ese. Your post made me wonder if a radio station located in a neutral zone -- an unrated market -- could use some positioner that was occupie/dtaken, and maybe even nationally copyrighted, by a station in an adjacent/rated market *if the newer station didn't stream*.
How far might the cease-and-desist writ run if the copyrighted station puts a decently listenable signal into the unrated county or counties?
The broadcast dials and the internet are two separate sources of entertainment in 2018, no? Yet, of course, there's bound to be some overlap and conflict while two sides argue as to which station, service-marked or grandfathered or not, is allowed to use The Vulture, or Magic, or The Goose, or Mellow, or Fuming, or The Stork. I'm thinking that a non-streaming local station should be clear to be whoever they want to be -- especially if they do not stream nationally.

Several of us consigned an attorney up this way to outfit the group with a company name for a non-profit organization. The enterorise was a small one ... voice work .... maybe a small licensed station .... impeccable references for all involved .... beer money .... a hobby, etc. All the priorities (although not necessarily in that order). It cost several hundred bucks, but we wound up chartered in two different states with the name.
We had expected some Perry Mason type of research .... he with a two-fisted Bulldog Drummond aura and some law clerk poring through mesas of books in a vast law library.
Nope. The attorney, who looked like David Ogden Stiers, instead went to a flippin' COMPUTER and looked up the group's desired name.
'Nope. Nothing,' he said, after a few scratched ear-lobes and mouse clicks and screens showed up. 'You guys are cleared. Nothing with that name is taken.'
