No, and no. TMISU are definitely stretching things a bit.
KTAR wasn't even the first station in Phoenix, let alone Arizona. Depending on the interpretation, that honor goes to the short-lived KDYW (5/15/22-4/4/24) or 6BBH, which started broadcasting under an Amateur license in October 1921, but became officially licensed as KFCB (now KOY) on 9/16/22.
KDZA Tucson also preceded KTAR, having been licensed on 5/19/22. It was owned by the Arizona Daily Star. Like KDYW it didn't last long. According to Barry Mishkind, KFDH, another short-lived station owned by UofA, started broadcasting as ham station 5YP (shouldn't that be 6YP?), but it wasn't licensed as a broadcaster until December 1922.
KFAD (now KTAR) came on the air on 6/21/22. They can legitimately claim that they're the oldest active broadcast license in Arizona (KOY and the late KFDH were still licensed as Amateur stations in June 1922). But the first station in the state? Not by a long shot.

And KT'R has the state's largest radio audience? Doubtful. If they don't have metro Phoenix's largest audience, how could they have the largest audience in the entire state? Methinks TMISU are playing fast and loose with the facts.
