I have no doubt that CC partially made the move to protect the mothership (DVE), and it did hurt KDKA to lose Rush Limbaugh, I think we all agree on that, but CC also had an outlet for Rush in this market in 104.7. If 104 was still playing any of the various forms of music that failed on that signal instead of doing talk, they may have just left well enough alone and not bothered with pulling Limbaugh, but since they had a talk outlet, it only makes sense to have that valuable of a property under their own roof.
I don't know how the Boortz program worked over at 104.7. I may be mistaken here but I thought he was live from 10am-1pm, so I don't know if they taped delayed the whole thing or carried the last hour live then replayed the first two hours from 1pm-3pm. If it was all on tape and they let Boortz's meltdown on the air happen anyway, that is near inexcusable.
Hoerth was briefly the morning guy at WPTT for a little less than a year when Bowyer requested he be moved to afternoons to accommodate his now longer drive into the station, after moving from McKees Rocks to Boston PA and the fact he ws doing fill in work for Los Angeles, which left the station juggling its most effective lineup, which was Bowyer,Cullen, Hoerth to Hoerth, Boortz, Cullen, Bowyer. Bowyer then left, making the whole readjustment of the programming schedule to accommodate him a moot point, Hoerth was juggled back to afternoons, and Cullen was moved to mornings. In any incarnation they had however, the best numbers they got were during Cullen's show, and with Cullen doing middays with Bowyer as a lead in and Hoerth on afternoon drive, you had some audience that would tune in early and catch part of Jerry's show and stick around and catch part of Doug's show.
Hoerth actually didn't hate being the morning guy at WPTT, if anything he hated having the schedule bounced around to the point where he couldn't have the opportunity to build an audience. In the span of a year he was pulled from afternoons to mornings and no more than got comfortable doing mornings than he was put back on afternoons. He often on the air talked about his previous run in mornings on 1250, but that had to do with doing a 5 hour morning show (5am-10am) and the fact that station was constantly under threat of being sold and he was the last left of their talk lineup, creating a situation where every day he wondered if he would have a job. But the idea that he didn't want to go on at 7am at WPTT is a flawed one, management made the decision to put Doug back in afternoons and not Hoerth.
In any event, any syndication that WPTT offered for middays never held its audience. Hoerth's show was something that could hold an audience, but wasn't as strong at building one from scratch, which is what is required of a show that has a simulcast of the Channel 4 News as its lead in. You are absolutely correct that the station would have been better served to keep its live talent back to back in that regard. I would argue they would have been better off getting another live talent to replace Bowyer and maintained the idea that they were the only station in the market that was live and local all day long, but that costs money, and money wasn't being spent there. The advertising/promotion budget consisted of the original bus signs when they first started the talk format and nothing after that. Even now, the few billboards that pop up on electronic signs around the area are paid for by Ron Morris, not the station.
