N1IN writes "Ham operators are invited to join the 51st celebration of U.S. Armed Forces Day by exchanging contacts with Army, Air Force, Navy-Marine Corps and Coast Guard radio stations during the weekend of May 12-13, 2001. The military holiday actually falls on May 19, but the office of Secretary of Defense Donald Rumsfeld rescheduled the traditional cross-band communications test so it would not conflict with a major ham event, the Dayton Hamvention which takes place May 18-20. During the cross-band test, military stations in the U.S., Europe and Pacific will listen on the ham bands and transmit on government frequencies, a mode of operation similar to the split operation used by many DX stations. Amateur stations can determine where to transmit by listening on the predesignated government frequencies. The full listing of stations, frequencies, hours of operation and operating instructions will be available on the Internet. From 7 a.m.EDT (1100Z) on Saturday (individual stations' hours will vary), 14 military stations will be on the air on sideband and will exchange QSL cards. Nine additional stations will transmit the Secretary of Defense's Armed Forces Day message at stated intervals via digital modes including Pactor, Amtor, GTor and Clover. Special commemorative certificates will be awarded hams who submit successful reception in hard copy. See the Internet for full information. "These tests give amateur radio operators and short wave listeners an opportunity to demonstrate their individual technical skills and receive recognition from the Secretary of Defense or the appropriate military station for their proven expertise," the chiefs of the Army, Air Force and Navy-Marine Corp MARS (Military Affiliate Radio System) said in their announcement of the event. Full text of the announcement is available at the following regional Army MARS web sites: www.angelfire.com/mt/armymars2/AFD_1_.txt "
