I believe 93.9-2 was running from a web stream in it's final months, so that would make sense that WGCI HD2 was turned off earlier. It's the same one showcased in this article from April of last year. WLIT HD2 cut from it's own local feed to this one at some point last year. The fact that it was from a stream would make sense as to why it ran longer. This feed is the one that has been shutdown nationwide.
