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:
