I regret that I can not receive images from ramsat satellite in Europe. My DSSTV transmitter is based on a raspberry pi 0, The camera takes images in the stratosphere to jpg format. Over this is superimposed telemetry information from sensors connected to the rpi. This image is then subjected to additional processing adding redundant reed-salomon information. And transmitted using the SA828 module or rpitx software directly from the GPIO pin on the raspberry. Receiving and decoding is done in the publicly available easypal software. In the news - I recently built a DVB-S digital TV transmitter, which transmitted from a height of 32km video in full HD resolution 1920x1080.
