[SJDXA] Armed Forces Day Crossband Test

Fri Apr 1 09:05:15 EDT 2022

The Army Military Auxiliary Radio System will host this year's Armed Forces
Day (AFD) Crossband Test on May 14, 2022. This annual event is open to all
licensed amateur radio operators and will not impact any public or private
communications. For more than 50 years, military and amateur stations have
taken part in this event, which is an interoperability exercise between
hobbyist and government radio stations.

The AFD Crossband Test is a unique opportunity to test two-way
communications between military communicators and radio stations in the
Amateur Radio Service (ARS), 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 will transmit on selected military frequencies and will
announce the specific ARS frequencies monitored. All times are ZULU (Z), and
all frequencies are Upper Side Band (USB) unless otherwise noted. The
frequencies used for the test will not impact any public or private
communications and will not stray outside the confines of the exercise.

The following stations will be making two-way radiotelephone contacts with
stations in the ARS between the time periods listed on the frequencies
listed in Kilohertz below.
