Clarification, looks like KFAN changed hands and is now KTLK news talk,
transmitter is still at the same location and daytime power is at 50 Kw,
nighttime switches to 25 Kw.
It's difficult to keep up with these stations, call letters and ownership
changes hands so often. At least they're news talk, rather than sports talk
all day long must have gotten real old. Clear Channel owns the station now.
That's all.
