They can't move it in, as there's the 93.7 in Georgetown that simulcasts I-100 out of Myrtle Beach and comes in well in northern Charleston county.
Mr. Hess didn't run that station well. The jingles have been the same for at least a decade, probably more. A big hodgepodge of stuff (country music, almost all automated except for morning show), local and national news (for several years ran hourly network news), lots of sports (Braves, NASCAR, South Carolina, Phil Kornblut), the swap shop every morning, obituaries, and a lot of syndication.
Colleton County football was the only thing that made money there, and that dates back to the WONO days. Another owner would help that signal a lot.
Kirkman could buy it and simulcast one of their sports stations (FM sports?) or maybe WJNI. Apex could buy or LMA it, and do several things with it. If they could pair it with 99.3, that translator, you could have a very good signal. 93.7 covers most of Colleton, western Charleston, and a good amount of Dorchester well, while 99.3 is good inside 526 and in West Ashley. It probably would be just as good as 98.9 in the metro.
You could run any number of formats with Apex, or another local owner could get it and run it the way they want it. This signal shouldn't go away.
Most of your suggestions would drive yet another local radio station straight into irrelevance.
