The US Department of Defense will host this year's Armed Forces Day (AFD) Cross-Band Test on Saturday, May 14. While Armed Forces Day is May 21, the AFD cross-band military-amateur radio event traditionally takes place 1 week earlier to avoid any conflict with the Dayton Hamvention^®.

In addition to the two way communications exercise, an AFD Secretary of Defense message will also be sent in RTTY, and an AFD message will also be transmitted utilizing the Military Standard (MIL-STD) serial PSK waveform (M110), followed by MIL-STD Wide Shift FSK (850 Hz RTTY), as described in MIL-STD 188-110A/B.

A detailed list of modes and frequencies for military/government stations taking part in the Armed Forces Day Cross-Band Test and information on the AFD message is available at www.dodmars.org. In the upper right corner is a dropdown with all the information.
