WMGF broadcasts with an effective radiated power (ERP) of 100,000 watts from a transmitter on Miller Road in Orange City, Florida. The station can be heard as far as Jacksonville to the north, as far as Sebastian to the south, and is one of the few Orlando stations that covers Ocala and parts of Gainesville.

Another subchannel rebroadcasts the talk radio programming of co-owned WFLF 540 AM.
History
WHIY and WORJ
In February 1966, the station first signed on as WHIY, powered at 28,000 watts and owned by the Orlando Radio & TV Company. In 1969, Orlando Radio & TV bought WORL Orlando (now WIWA in Eatonville), operating the two stations together from offices and studios in Orlando. In the early 1970s, 107.7 began airing a Top 40 format, switching to the call letters WORJ, standing for "Orange," a major crop in Central Florida. By the late 70s, the station had switched to an album rock format, calling itself "Zeta 7."

Why this record matters
The phrase “adult contemporary radio station in Mount Dora, Florida, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q7952798. The first chronological checks are 1966, 1969 and 1978.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
