Oddly, benale, on two separate casual occasions, I've gotten WDAS up this way recently -- both with the soul-oldies and the newer format. We're about 100 miles NNW of Philly and way out of even their fringe. But if the radio is sensitive enough (and it is), well *something* has to come in. 1480 has been vacant locally since WISL Shamokin went dark. 1480 is a cool DX channel, especially around sunset and just after sunrise.
Anyway, perhaps when the WDAS version of Smooth Jazz doesn't tilt the earth's axis, Clear Channel will try the Quiet Storm format.
Got a question myself about the demo issue. WPPZ shows up pretty well, and has for several years now 6-plus. I remember seeing them around 3.5 in the diary days. What is their chief demo strength?
