Making tracking of the high-altitude balloon flight OH3HAB 7 a community effort. Watch the epic landing in a river!

The high-altitude balloon flight OH3HAB #7, launched on September 2nd 2023 by amateur radio club OH3AA in Hämeenlinna, Finland, was a special flight with two new technical experiments: a RadSens radiation sensor based on a Geiger tube and an image transmitter using the Wenet modulation. The flight payloads included a Vaisala RS41 radiosonde that was repurposed for amateur radio use and a Raspberry Pi Zero W with a Uputronics LoRa board to transmit photographs. With the transmissions of the position and image data available for anyone to receive easily, tracking of the flight became a true community effort!
