WAAF, a staple of rock radio in the Worcester and Boston markets, has been sold for $10.7 million to Educational Media Foundation, Entercom Communications announced Tuesday afternoon.

Entercom said it will continue to air WAAF on its existing HD stations 104.1 HD2 and 93.7 HD2 and on RADIO.COM.

Educational Media Foundation will begin programing on 107.3 FM on Saturday. The transaction is expected to be completed in the second quarter of 2020. It’s unclear what plans Educational Media Foundation has for 107.3 FM.

WAAF lost one of its biggest names, Greg Hill, last year when Entercom announced he would join the morning show on WEEI.

Hill served as the host of WAAF’s “Hill-Man” morning show for more than 28 years. He joined WAAF in 1986. “The Greg Hill Show” currently airs mornings from 6 a.m. to 10 a.m. on WEEI.

At the end of last November, WAAF announced a 50th anniversary concert that included performances by Godsmack, Halestorm, Dinosaur Pileup, Dirty Honey and Theory of a Deadman.

The concert is scheduled for April 16 at the DCU Center in Worcester.
