HAVERFORD, Pa. (AP) – A tiny high school radio station outside Philadelphia is turning 60.

WHHS at Haverford High School turned 60 years old on Sunday. Founded in 1949, the 10-watt station is the oldest high school FM station in the country.

The station has had three different spots on the FM dial, settling at 99.9 since the 2005-06 school year.

Faculty advisor Ed Weiss calls the station the school’s “hidden gem’’ that always has a waitinglist of student applicants.

The station threw a party Friday to mark the anniversary.
