[4] WGTS began as a 10-watt campus broadcaster in 1957, operating from the basement of the men's dormitory at the then Washington Missionary College in Takoma Park.

A $10 million initial offer by the WGTS board of directors to keep the station within Washington Adventist University was rejected.

[10] In 2018, the Washington Adventist University board voted to spin off WGTS to a new nonprofit, Atlantic Gateway Communications, for a purchase price of $12 million.

[12] In March 2021, AGC and WGTS announced a deal with American University-owned WAMU to acquire the NPR station's Ocean City, Maryland-based repeater, WRAU (88.3 MHz) for $650,000.

[13] WGTS raised some $700,000 from listeners and supporters to fund the sale,[14] giving the station a 50,000-watt repeater service for contemporary Christian programming on the Delmarva Peninsula.
