A lot of radio amateurs bemoaning the recent spate of poor HF conditions would love to have a way to improve propagation — perhaps without even having to rely on the whims of the Sun. The US Department of Defense is thinking along the same lines. An August 9 article in New Scientist reports that the US Air Force is exploring a plan to bombard Earth’s upper atmosphere with ionized gas dispersed from CubeSats. According to the New Scientist article by David Hambling, the Air Force hopes to improve long-distance radio communication by “detonating plasma bombs” in the upper atmosphere, and the military branch has contracted with corporate and university researchers to figure out how to make this a reality.
