Seen as a complete failure - and down trending the last 4 books, WKNL "Roxy 100.9" switched formats to oldies (70's/80's) today at noon. The new K-Hits features songs from the 70's and 80's. This is the third format change for the frequency in 5 years, after abandoning the successful "Kool 100.9" 60's/70's format.
