At 1200Z today, Jonathan Trappe KJ4GQV took off from Caribou Maine beneath a cluster of 370 helium-filled balloons in an attempt to cross the Atlantic Ocean.
Ham that he is, he’s carrying beacons transmitting on 14.0956 MHz (110 Baud ASCII RTTY using the callsign NG0X) and 144.390 MHz APRS (using KJ4GQV).
The trip could be as long as 2,500 miles (4,000km) and take between three and five days. Depending on the weather, he could land anywhere between Iceland and Morocco and will fly at altitudes up to 25,000 feet (7600m).
UPDATE: He’s landed safely in Newfoundland – well short of Europe…
