The Army Military Auxiliary Radio System will host the 2022 Armed Forces Day (AFD) Crossband Test on May 14, 2022.
A list of participating stations, modes, frequencies, and times will be published April 1, 2022, on the DoD MARS - Armed Forces Day page
The AFD Cross-band Test is a unique opportunity to test two-way communications between military communicators and radio stations in the Amateur Radio Service, as authorized in 47 CFR 97.111. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly controlled exercise scenario that does not impact any public or private communications."
Military stations in various locations will transmit on selected military frequencies and announce the specific ham band frequencies they are monitoring. 1
