Lawppy's post about 103.7 in Winterset, IA, sounds just like what I'd expect.
About 1310 in Lorain/Sheffield Township -- I'd guess you might hear interference from local WOBL from Oberlin, OH (where I attended college!) on 1320. Otherwise, I'd guess WDTW from Detroit (which I understand is off the air or going off soon) would be what I'd expect to hear maybe along with WDPN from Alliance, OH, which is about 60 miles ESE.
Nighttime, I have no idea. I don't think CIWW, given its pattern, would make it there from Ottawa. If not WDTW, then maybe WTLC from Indianapolis, but that seems like a stretch too.
