The 2022 running of the Armed Forces Day (AFD) Cross-Band exercise will 
be held on May 14, 1300 – 2200 UTC. A complete list of participating 
stations,modes, frequencies, times, and other detailswill be announced 
<https://www.dodmars.org/mars-comex-information-website/armed-forces-day>on 
April 1.The event is open to all radio amateurs. Armed Forces Day is May 
21, but the AFD Cross-band military-amateur radio event traditionally 
takes place 1 week earlier, in order to avoid conflicting with Dayton 
Hamvention®. During the exercise, radio amateurs listen for stations on 
military operating frequencies and transmit on frequencies in adjacent 
amateur bands.

Military and amateur stations have taken part in this event for more 
than 50 years. It’s an exercise scenario, designed to include ham radio 
and government radio operators alike.

Per previous announcements: “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.

An AFD message will 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. The AFD message will 
also be sent in CW and RTTY.

Full details will be released on April 1.
