WQXI is LMA'd to Big League, so it's in good hands for now--no rush. However, WSTR needs help--and like most unintentional owners of any kind of property (Lincoln got the radio stations when they bought Jefferson-Pilot), they probably don't want to put much into it. However, the longer it sits without maintenance, the less it will be worth. And, as oftentimes is the case when selling a house, your first offer is often your best offer. I think Lincoln is being greedy and the 5 C's know it, and they're keeping their powder dry.
Did you see that survey in allaccess.com of CHR station ratings in the what, top 25 markets--and WSTR was dead last (not counting CHR stations new this book).
Does Big League own any stations outright? If so, they would be a logical buyer for Quixie. No compelling reason to sell them both as a unit, especially if Lincoln wants top dollar.
If WWWQ @ 99.7 does well, and Z90-Dave picks up a point's worth of 99x listeners, WSTR may be next on the format rotisserie.
