Its broadcasting range extends to western and central Massachusetts, northern Connecticut and southern Vermont and New Hampshire. WFCR's studios for most of its history were located at Hampshire House on the campus of the University of Massachusetts Amherst. However, in 2013, the station moved most of its operations to the Fuller Building in downtown Springfield. It airs a mix of NPR programming and classical music.
The station signed on May 6, 1961 as a repeater of WGBH in Boston. However, by 1964, it had expanded its local programming to 17 hours per day. The call letters represent "Four College Radio" becoming "Five College Radio in 1966". It was a charter member of NPR, and was one of the stations that carried the initial broadcast of All Things Considered.
WFCR claims the distinction of being the first radio station in western Massachusetts to transmit a signal using iBiquity's HD Radio system. It airs two digital streams. The first is a simulcast of the analog signal, the second is a 24-hour classical music station.
Until 2010, WFCR provided the station's programming, while Clear Channel sold underwriting advertisements. However in July 2010, WFCR purchased WNNZ from Clear Channel for $525,000. The sale does not include the transmission towers, but rather has a lease clause in the sale agreement in which Clear Channel will own them and lease them to WFCR. WFCR purchased the license from Clear Channel under the name of "WFCR Foundation Inc." The FCC approved the sale August 25, 2010. Prior to 2007, the programming heard on WNNZ was heard on WPNI, 1430 kHz, in Amherst, which was owned by Pamal Broadcasting.
WFCR, again, under the licensee name of "WFCR Foundation Inc.", acquired the license of WGAJ 91.7 in Deerfield, MA from Deerfield Academy. The license transfer was granted on August 19, 2010. WFCR paid Deerfield Academy $10,000 for the signal. The call letters of the station were changed to WNNZ-FM as of September 1, 2010.
WFCR won the allocation of 98.9 in Adams, MA, in FCC Auction #91 (under the applicant name, WFCR Foundation Inc.) WFCR won it for $189,750. WFCR has filed the application for new station with the FCC, to transmit the new signal from the top of West Summit, in North Adams, MA. (Where the current WUPE-FM transmitter site is located. WFCR already has a translator, W266AW, located there.)
