WYPR is a public radio station serving the Baltimore, Maryland metropolitan area. The station broadcasts on 88.1 MHz on the FM band. Its studio is in the Charles Village neighborhood of northern Baltimore, while its transmitter is westward in Park Heights. The station is simulcast in the Frederick and Hagerstown area on WYPF (88.1 FM) and in the Ocean City area on WYPO (106.9 FM). Surprisingly, the two stations on 88.1 are not synchronized. WYPF's sound is about 1/2 second behind WYPR, rendering WYPR almost unlistenable in some portions of Howard and Carroll counties.
