If anyone is interested I launched a balloon yesterday with a TTN GPS tracker attached. At the time of writing it is heading north over Wales at an altitude of about 9.5km and transmitting on EU868.
Not sure how long it’ll stay afloat and functional for but if anyone under the flight path wants to check for it on their gateway logs then the device address is 260118F6. It’s solar powered so will only TX in the daytime.
The flight can be monitored here:
