Originally a typical freeform college radio station, it boosted its power to 25,000 watts in 1985, allowing it at least secondary coverage of the entire Baltimore/Washington corridor.
Johns Hopkins put the station up for sale in 2000, due to the expense of maintaining it, as well as a change in focus that no longer included radio.
In 2004, Your Public Radio Corp. bought religious broadcaster WJTM in Frederick, which became a relay of WYPR with the call letters of WYPF.
On July 30, 2007, Your Public Radio Corp. bought Ocean City, Maryland alternative rock station 106.9 WRXS, which began simulcasting WYPR starting September 10, 2007.
