> couldn't someone buy WVIM and WBTG in Brownsville and set up a simulcast that would cover a larger area...
Well, I suppose one could, but, the larger question is why?
Adding Brownsville to the mix would still not accomplish what WVIM desires most -- a signal in Shelby County. While WVIM covers little of Shelby County, Brownsville covers even less. As I mentioned, it does put a 40 dBu over a very small sliver of NE Shelby County, but that's it. 40 dBu contours aren't worth much, at all, and even so, it is subject to horrible co-channel and adjacent channel interference. So, the fact that Brownsville is on 95.3 is merely incidental. Linking the two stations would only add Haywood County.
Further, buying Brownsville and taking it dark still wouldn't allow WVIM to move north. The other factors like adjacent channel stations, and the need to maintain a City Grade over Coldwater (unless or until a new FM signal is allocated there -- and don't hold your breath on this one) still keep it south.
So, again, until something of seismic proportions happens, WVIM will remain a DeSoto station. But, that's not necessarily a bad thing.
