The station's studios are located in Winchester while the transmitter (shared with WXVA) resides south of the city in nearby Kernstown.

WINC had difficulty renewing its license in the early 1970s, as it was airing 22 minutes of commercials per hour—in excess of what the Federal Communications Commission (FCC) permitted.

WINC began simulcasting full-time over 104.9 FM (then WZFC) on January 31, 2018,[19] but this ended in mid-November 2020[20] when Centennial sold the first WINC-FM, in operation since 1946, to Educational Media Foundation.

[26][28] However, the pending implementation of the North American Regional Broadcasting Agreement (NARBA) mandated that on March 29, 1941, most stations on 1370 AM would move to 1400 AM, so the authorization specified this adjusted frequency.

[9][30][31] Two weeks later, on July 13, Virginia Senator Harry F. Byrd and Governor James Hubert Price attended the dedication of the station.

[37] Less than six months after the station's first broadcast, WINC carried live descriptions of the attack on Pearl Harbor and President Roosevelt's "Infamy Speech" the following day.

[57] Mark Sheeler, a disc jockey at WINC, gave a "wolf whistle" as the signal for Winchester area "housewives" to call the studio.

[60] Fourteen-year-old country music singer Virginia "Ginny" Hensley, who later became Patsy Cline, began her career by making her broadcast debut on WINC in 1948.

[16][61][62] Hensley asked "Joltin'" Jim McCoy, the leader of a "hillbilly band" called "The Melody Playboys", about to perform on the station, for a chance to sing with them.

[73] The station applied for and received a construction permit on August 9, 1958, to increase its broadcasting power from 250 to 1,000 watts, both day and night.

Paul Harvey, in town for a speaking engagement, broadcast his "News and Comment" program from WINC studios on April 14, 1962.

[83] WINC remained an ABC Radio affiliate in 1978, carrying its American Contemporary Network with a middle of the road music format.

[17] A license plate number of a car with a WINC bumper sticker was announced over the air, and the owner was given 92 minutes to call in and choose to accept a prize of $92 or give up the money for a chance of winning $9,200.

[17] On December 19, 1988, Winchester Circuit Court Judge Perry Sarver ruled in favor of WINC stating he did not believe "promotional plans such as was used ... are in violation of the lottery statute".

[105] The price of the sale, initially reported at $36 million, also included WINC-FM, WWRT and WWRE in Winchester and WBQB and WFVA in Fredericksburg.

[106] Centennial CEO Allen B. Shaw, commenting in a Winchester Star interview on the sale, said he had been considering buying the company for several months.

[19][111][112] The addition of the FM simulcast was something operations manager Mike Herald had considered "for quite some time" but only brought to fruition due to the current political climate.

[113] Herald felt the "conservative lean" of the hosts aired by WINC would "resonate really well with the folks here in the valley" as "Mr. Trump has made things very exciting".

[20] Following that realignment, Centennial agreed to sell WINC-FM and WZFC to Fairfax, Virginia–based Metro Radio, Inc. for $225,000,[22][116] a deal made mostly out of "financial considerations".

[117] As a result, WINC and its long-time studio facility which the station has been in since its launch were now the only remaining pieces of the original Lewis cluster.

[37][38][116] Allen Shaw said in a May 2021 interview with the Star that WINC hadn't experienced "great financial success" further compounded with the recent death of Rush Limbaugh, whose syndicated show had been a long-time fixture on the station.

While Shaw said he would "hate for" WINC to "go dark", he "[couldn't] rule it out", but hoped to either donate the station to a nonprofit organization or sell it "if the right buyer came along".

[7] The next day, on July 1, 2021, Colonial Radio Group of Williamsport, LLC, began operating WZFC via a local marketing agreement with an option to purchase for $25,000.

[6][7][118][119] Colonial owner Todd Bartley told the Star, "it's a tremendous honor to take a legacy [station] like this one forward".

[6][7] Had Colonial not purchased WZFC, the station would have ceased broadcasting with the license returned to the FCC, a possibility Shaw felt "would have been bad" for the region.

[120][121] Under the Colonial name, Bartley previously owned WEJS and WLYC in Williamsport, Pennsylvania, but the two stations were taken under receivership and divested by a bankruptcy trustee in 2020.

[7] WZFC's studios and transmitter site were not included in the sale; Centennial disclosed that the building would either be sold or demolished, while the tower would be taken down "eventually".

[123] Bartley went on to say while Colonial intends for WZFC to carry additional local fare, the station's existing talk format would be retained.

[125] Jones, a certified public accountant by trade, organized the purchase on referral from Bartley in reaction to Metro operating WINC-FM as a Leesburg station from Chantilly[123] with no Winchester-based programming.

[130][131] Weekend programming on WINC includes home-improvement shows In the Garden with Andre Viette and At Home with Gary Sullivan.
