according to GritTV facebook post it is on 46-3
Grit has expanded into new territories! <snip>
Flint, MI-WBSF Channel 46.3
Crap, I can't get that station very well and keep it locked unless I redo my antenna's, which means more money. It's way off from all the others, and only a clone of WSMH-66, which I do get, so I wasn't concerned with also getting this one. Apparently, it's no longer just a clone if it also has Grit.
By the way, it's in Bay City, NOT Flint. They are using the OLD Wnem tv-5 tower in Indiantown.
Ok, I was able to scan it in and lock it long enough to check it. It's nothing but color bars, with no broadcasting or anything else right now.
