WMTR-FM
WMTR is also the call sign of an FM station in Archbold, Ohio at 96.1 FM. WMTR-FM is in no way associated with WMTR 1250. They only share call letters. This was not allowed until the late 1980s. Until then, stations that shared call letters had to be co-owned. When co-owned AM, FM, and TV stations were sold to separate owners, call letters for the FM and TV stations would have to change. For example when WOR-TV was sold, WOR 710 kept the original calls while the TV station became WWOR-TV. Today, different companies sharing the same calls is an option.
