Well done everyone involved
This is proper boffinry combined with international cooperation that came together over the Internet and all in the name of fun and science.. It's what a less cynical me from a couple of decades ago was hoping for.
Blighty's two-pronged High Altitude Ballooning (HAB) assault on Europe over the weekend ended dramatically with the rescue of one payload from the slopes of a snow-capped Austrian mountain, while the other is officially AWOL somewhere in France. Low Orbit Helium Assisted Navigator (LOHAN) team members Dave Akerman and Anthony …
Something was clearly (and poorly) edited from the first sky pic, near the bottom right corner. What did they find up there? Evidence of the sky-beasts that roam above us? An intelligence from beyond the stars? The newest project from the marvelous mad scientists at DARPA?
Tinfoil hat is firmly in place. Black choppers are circling. Conspiracy time is go!
One wonders what the (over)reaction would have been 30 years ago to balloons from the UK crossing into Czech airspace and then being rescued by a team of Slovenians. Might have made a good "race to get their first" spy novel though!!

Being an anorak-wearing radio ham, how have you got permission to use the 70cm band for link-back via APRS? Aeronautical mobile operation is strictly prohibited. Even trying to use so-called licence-free radios at 70cm would not cover this activity. This would be bad enough in the UK but across several countries in Europe it would be a licensing nightmare.
We use the license exempt 70cms band to transmit RTTY at 10mW. You don't need a license to do this and it is permitted for airborne usage. The APRS was transmitted on 144.800Mhz but to comply with the legislation in the UK the transmitter wasn't enabled until it left UK airspace. There are other European countries where its not permitted so the code had geofences in to disable the APRS to comply with the local laws.
Additionally the code prefixed my call sign with the correct ITU prefix i.e DL/M0UPU. The law is a little silly in this respect as the transmissions were received by UK stations and igated whilst the payload was over the Netherlands/ Germany.
