TV presenter Jason Bradbury 2E0JAB was among those present at a mass launch of 25 balloons transmitting in 434 MHz on Thursday, May 12, 2016.
Balloons from 25 schools were launched in batches of five from RAF Cosford. Each balloon carried a payload incorporating two small cameras and the Raspberry Pi In The Sky telemetry tracker. The balloons transmitted on unique frequencies ranging from 434.040 to 434.790 MHz.
Jason Bradbury’s balloon reached an altitude of 33 km before it burst and the payload parachuted back to Earth. The next problem was finding it. He tweeted:
Call out to my radio amateur friends. Need help finding 434.04mhz telemetry binary code
The balloon was eventually found stuck up a tall tree.
