Further explanation for the ID interest
1: The network's website lists 20+ full-power affiliates. More than a few are missing from said ID. Having listened to your clip (thanks) I now wonder if some have local-insert capacity.
2: Call me odd, but in an era of when most stations' real City_of_License (I know, what's that?) ID is hidden somewhere deep in the programming clock, it's a charming throwback to hear 40+ seconds of real ID at the top of the hour.
3: This poster goes back to when JS had one wheezy AM daytimer here in Baton Rouge. JSM website lists 78 current stations and translators, most of them FM.
4: When $3M+ (that's 3 Million dollars, folks) changes hands for a non-commercial, unbuilt CP, that gets my attention.
