Mass amateur radio balloon launch by USA schools


On October 9 amateur radio balloons were launched from schools across the USA each with APRS on either 144.390 MHz FM or 144.340 MHz FM. They are heading East around the world

The 11 balloons seem to be floating at an altitude just above 20,000 feet (6-7,000m) and it’s expected they will take a few days to cross the Atlantic.

The Smithsonian National Air and Space Museum site reports:
“Families can follow along as the balloons are launched into the air and travel across the globe. The balloons will be tracked by HAM radio and their locations will be updated online!”

One of the balloons is KE0LYF-1 from Minnesota; its real-time track can be seen at!mt=roadmap&mz=4&qm=1_day&f=KE0LYF-1&q=!RS_*;
