    ANNUAL ARMED FORCES DAY CROSSBAND TEST (07-08 May 2021)

    The Department of Defense will host this year’s Armed Forces Day (AFD) Cross-Band Test, scheduled for May 7-8, 2021. 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 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.

    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. Technical
    information regarding these waveforms is provided at:

    Are SHARES stations permitted to make contact on the MARS (non ham radio) frequencies listed. I have my old ax.25 Navy Mars call assigned as my SHARES call sign.

    You bet and please do! Same here, my AFMARS is my SHARES call.

    Thanks for the reminder Peter. :) Would you know if they establish any hierarchy or NTS system this year?

    I know in 2019 they was some trouble with different regions bumping into each other, and a few big power stations dominating the frequencies.

    Well, they pretty well destroyed any other activity of 60 meters.

    One day on 60M is that important?
