AMSAT/APRS ops needed in Europe to track trans-atlantic balloon! Here is the last position copied on APRS with it 500 miles out to sea headed for Europe.. http://aprs.fi/?call=k6rpt-11&mt=roadmap&z=7&timerange=172800&_s=ss_call
Its on USA freq of 144.39 so will not be heard in Europe except by people specifically tuning for it. Just point your high gain beam east and monitor 144.39 and capture any of the 1200 baud AX.25 packets!

What's the radio range at 107k ft...? My calculations show about 407 miles line-of-sight (over the horizon) to a 30' tower and 470 miles diffraction corrected radio range, it looks reasonable. Anybody know a URL for real-time jet stream maps/plots? Go baby, Go! -- 73, Steve, K9DCI USN (Vet) MOT (Ret) Ham (Yet) -- I served during the cold war, so you can continue to be served a cold one.
