Evuguy - WDCX is definitely on the air here in Rochester. Not sure why you're not hearing it across the lake.
As Saul correctly notes, there's no one "official" way to count a new station. From an RF perspective, there's nothing significantly different between the old CFIE 106.5 and the current CKAV, or between CKLN and CIND, even though they're new licenses on paper and using new equipment.
For that matter, CBLA is basically the same signal that was CKO. So you'd have to dig into the legalities of the situation - that an earlier license was shut down and a new one replaced it - to make the plausible argument that those are all new stations.
There's always going to be a fudge factor, because it's always a moving target. When CJBC-FM signed on at 90.3, it was on the CN Tower. Now it's on First Canadian Place. Different signal, to some extent, but nobody would argue it's not the same station.
Same for CHIN 1540. It's definitely a lesser signal than what it was from the island, but still the same station... right?
