1. Not a chance in hell. First off, KBEH (and KWHY) operate on RF 4, and their over-the-air signal is weak at best. It'll be asinine just to move The CW off of KTLA, just to put it on a signal that no one doesn't (or can't) watch. Why do you think KBEH has gone through multiple programming format changes over the years, since the change to Spanish-language programming and its re-allocation as a Los Angeles DMA station years ago? All said that, especially for Los Angeles market prices, I don't think Meruelo wants to spend the programming costs to stock-up KBEH (or KWHY) with viable programming, beside the junk pay-for-play they already air on 63.
2. I think Weigel is content with operating the diginet setups they have outside of their core Midwest base (Chicago, Milwaukee, South Bend). Here with their KAZA/KVME/KPOM/KSFV setup, at least they don't have to pay any syndication dollars to air programming. This isn't like the three aforementioned cities where Weigel had years of establishing presence which enabled them to compete with the big stations in those cities, and even that took years for that to work.
3. LOL...again, not a chance in hell. Besides, if the McKinnons were to ever sell KUSI to Nexstar (personally don't see it happening for a couple reasons), that station would operate alongside KSWB, not KTLA, even though the latter two stations do share some of the management team. And why would KUSI, the
ONLY English-language independent station in the San Diego market, want to vacate there to become just another station in Los Angeles, especially being KTLA's dumping ground?
One of the reasons why we won't see this scenario play-out are those pesky "programming rights" issues...you know, the kind of issue where a TV provider would have to blackout certain shows because other stations in
THAT DMA are airing the exact same shows. Secondly, and the most important reason--duopoly rules. San Diego only has five full-power English commercial stations--KFMB, KGTV, KNSD, KUSI, and KSWB, and although KGTV and KNSD are a part of duopolies of their own, the sister stations to both are low-power licenses (KZSD and KUAN, respectively). So, in other words, unless one of those stations files a failing station waiver to stay in business, or KFMB (Tegna), KUSI, or KSWB (Nexstar) acquires a low-power signal to complement them, you will never see an English-language duopoly established in San Diego.
In some many words, your idea is a pipedream, and has no realistic chance in hell of ever happening. I'm done
