Air Force Research Laboratory Tracks Sporadic E
KIRTLAND AIR FORCE BASE — Researchers at Air Force Research Laboratory (AFRL) in New Mexico, have discovered a new way to track and characterize a phenomenon called “Sporadic E” naturally occurring in the upper atmosphere, where large structures of dense plasma form. These plasma structures, which occur at mid latitude locations around the world, disrupt radio frequency (RF) electromagnetic waves (or simply “radio waves”) and impact both DoD and civilian radio systems in positive and negative ways, depending on the application.

Plant protein responds to radio waves by making seedlings grow faster
A dose of radio waves seems to encourage plant seedlings to grow slightly faster, a find that, if confirmed, could have applications from farming to medicine. Margaret Ahmad at Sorbonne University in Paris, France, and her colleagues exposed thale cress seedlings (Arabidopsis thaliana) to weak pulses of radio frequency (RF) radiation at 7 megahertz, a frequency normally used by amateur radio operators.
I love events like this, and I love lighthouses, but I’m not sure that we should be holding these events just now, especially without masks….Dan
Lighthouse becomes a beacon for ham radio event
Local radio amateurs with the Bayouland Emergency Amateur Radio Service say the Aug. 21-23 events at Lighthouse Park in Berwick kicked off the most successful special event station ever at the park. The special event station put Berwick on the map for International Lighthouse and Lightship Weekend, during which ham radio operators at those facilities around the world try to contact one another. At the end of the weekend Aug. 23, BEARS operators had logged in and spoken to 310 ham operators from London, Portugal, Ireland, Mexico and Brussels in addition to stations throughout the United States and five lighthouses.
