I remember Dick Kemp, "The Wild Child". I always thought he was Gordon McLendon's idea of an answer to Dick Biondi. I don't know where he came from or where he went after WYNR w vai as blown up. My memory of the stunting when the station was that the various jocks that were hired were working their regular shifts. But repeating the same song, I could br wrong, but I remember multiple jocks. Also, IIRC Floyd Brown, before his WGN days was one of them. As was his brother Bruce, along with a few guys who evventually wound up at WVON. Yvonne Daniels also came on board early, but I'm not sure if she was there at the very beginning.
But, of course, 5kw directional at 1390 was no match for WLS. When WYNR was launched, I was starting my freshman year at Wauconda High School. The signal in Wauconda (11 miles east of where I live now) was fair at best, but usually listenable 24/7. On the one mile drive from the high school to my home there were 2 or 3 dead spots. Still, WYNR did manage to attract a following.
