According to The National Association for Amateur Radio (ARRL), elements of the US Department of Defense (DOD) will simulate a “communications interoperability” training exercise across the United States on November 04-06. The announcement released on October 24 has not been widely distributed to the media, because the drill is simulating a total grid collapse and could spark public fear.
Back in April 2017, we wrote an article titled ‘Yesterday’s Broad Power Outage Likely Caused By Geomagnetic Storm‘. While everyone thought terrorism was to blame, we correctly pointed out that large power failures in major US cities was due to an intense geomagnetic storm registering 8-10 on K-Planetary Index.
Back to the exercise on November 04-06, the US Department of Defense headquarters entity will work with the US Army and US Air-Force MARS organizations and the Amateur Radio community to request status reports for 3,143 US counties. During the exercise, communication frequencies will use HF NVIS, VHF, UHF, and non-internet linked Amateur Radio repeaters.
