Licensed to Miami, Florida, USA, the stations serves Miami-Dade, Broward, and most of Palm Beach Counties. WHDR is currently owned by Cox Radio, Inc..[1]  WHDR was originally WAFM, then WKAT-FM, then Classical WTMI, which ran from 1971 to noon, New Year's Eve 2001, when it flipped to a Pure Dance format and became WPYM, Party 93.1, South Florida's Pure Dance Channel. During its three year run, the station was popular with the area's dance music fans. The station earned an Innovators Award from Billboard magazine in 2002 and a Best Dance Radio Station Award at the 2004 Dancestar USA honors.

WHDR is South Florida's only pure rock station. The playlist ranges from 70's, 80's & 90's mainstream rock to newly released mainstream rock & active rock.
