ANNUAL ARMED FORCES DAY CROSS-BAND TEST (SAT. MAY 11th 2019)


The Army, Air Force, Navy, Marine Corps and Coast Guard are co-sponsoring the annual Military/Amateur Radio Crossband Communications Test. Although Armed Forces Day had traditionally been celebrated on the third Saturday in May -- this year it will be on May 11th 2019 as to not conflict with the Dayton Hamvention.

The annual celebration features traditional military-to-amateur crossband communications SSB voice and Morse code tests. These tests give Amateur Radio operators and short wave listeners an opportunity to demonstrate their individual technical skills and to receive recognition from the appropriate military radio station for their proven expertise. QSL cards will be provided to stations making contact with the military stations.

ANNUAL ARMED FORCES DAY CROSS-BAND TEST (11 May 2019)

US Army NETCOM will host this year’s Armed Forces Day (AFD) Cross-band Test on Saturday
May 11, 2019. 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 only an exercise scenario, designed to include
hobbyist and government radio operators alike.

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 (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 radio 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.
