Frank Alvin Delle Jr. and Eugene Joseph Gosselin, doing business as Radio Voice of Dover-Foxcroft, was granted a construction permit for a new station on 1340 AM on February 8, 1967;[4] it signed on August 13 as WDME.

[7] Radio Voice of Dover-Foxcroft also requested the addition of an FM allocation on 103.1 MHz on January 13, 1967;[8] a construction permit for a station on this frequency was issued to Delle on February 28, 1980.

[12] The new owners were Jim Ganley, who had worked at WWFX in Belfast before joining the May Company as a credit portfolio manager, and his brother Rick, an on-air host at WHEB in Portsmouth, New Hampshire.

[22] In November 1998, Thau moved WDME-FM's studios from the "Gulf Stream" rail car, which could not be expanded, to a former bank building in downtown Dover-Foxcroft's Union Square.

[24] After initially announcing a $175,000 sale to Taildragger Communications in May 2000,[24] Mid-Maine Media sold WDME-FM to the Zone Corporation—the broadcasting company owned by authors Stephen and Tabitha King[25]—for $175,100[26] in a deal completed on March 1, 2001.

Shortly after WZON (AM) began simulcasting WZON-FM on November 1, 2010, Red Sox games were moved exclusively to the AM station (which previously shared the broadcasts with WDME/WZON-FM).

The call letters were changed to WZLO on November 23,[31] and the station returned to an adult album alternative format, initially branded as "103.1 The Loft", on December 26, 2012.

[33] In late 2014, WZLO began to simulcast on the second HD Radio channel of WKIT; the subchannel, in turn, was relayed on Bangor FM translator W252CT (98.3), which had previously carried WZON.

[35] While King subsequently reached a deal to sell WKIT to Jeff Solari and Greg Hawes’ Rock Lobster Radio,[36] no announcements were made regarding WZLO or WZON,[37] and their December 31 closure went forward.

[38] In February 2025, the Zone Corporation agreed to sell WZLO, W252CT, and WZON to J Hanson's Mix Maine Media, operator of WBAN and WGUY in Veazie and owner of WFMX and WSKW in Skowhegan and WCTB in Fairfield.
