Fast HAB Imaging in the 868 MHz band
These days much radio experiment work takes place in license-exempt bands which are free of some of the restrictions of the amateur radio license

In his blog Dave Akerman M0RPI writes about his experiments using high-speed data transfer in 868 MHz to download images from High Altitude Balloons.

By using the the 250 kHz bandwidth option on the readily available LoRa modules a data rate of around 17,000 bps might be achieved enabling a 1280×640 image to be downloaded in about 70 seconds.
