WBUR, a Boston public radio station, said Tuesday that it has agreed to acquire the license to broadcast its programming on the 92.7 FM radio signal in Tisbury, a move that should expand WBUR’s geographical reach and bring its programming to listeners on Martha’s Vineyard and most of Cape Cod and Nantucket, as well as Southeastern Massachusetts, by early next year.

The seller is Aritaur Communications, which owns WMVY, a commercial FM radio station whose play list includes the likes of Neil Young, Stevie Ray Vaughan, Norah Jones, and Mumford & Sons. WMVY programming is currently broadcast on the 92.7 FM signal.
