Despite the station's transmitter location, WXRV attempts to primarily serve the Greater Boston area; its signal also reaches into the nearby Manchester and Portsmouth markets.

[4][5] For several months after Northeast Broadcasting acquired WKBR (1250 AM) in Manchester, New Hampshire, in 1997, that station offered a temporary simulcast of WXRV.

In February 1999, WXRV began simulcasting on WVFM (105.7 FM) in Campton, New Hampshire,[7] which Northeast Broadcasting had just acquired.

[8] For a brief time during 2012 and 2013, the station—which in 2005 had been renamed first WUSX[9] and then WLKC[10]—was programmed separately (though retaining the "River" branding and AAA format), before returning to the WXRV simulcast.

WFNX continued simulcasting WXRV until 2020, when it was sold to the Educational Media Foundation[20] and became K-Love station WKMY.

[21] In late May 2014, WXRV added a translator in Needham, Massachusetts, W243DC (96.5 FM);[22] the initial application for this facility had been made in 2003.
