 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. With the United States entry to World War II, WINC participated in the war effort on the air and at its studios. The City of Winchester erected an Aircraft Warning Service station, manned by volunteers, beside the WINC facility. The station aired an hour-long special program called "Virginia Schools at War Mobilization" on February 22, 1943. The program involved approximately 618,000 schoolchildren and teachers from around the state, war-savings staff, and state and civic dignitaries. The special, broadcast live from Mount Vernon, was carried on 13 other Virginia stations and on WWDC in Washington, D.C. WINC participated in another wartime broadcast, this one in late January 1944, to encourage the public to buy War Bonds. A total of $ 150,525 in bonds were sold during the two-hour program, broadcast on 13 stations in Virginia and 1 in Washington, D.C.
