Mario Roessler DH5YM has made available a video showing amateur radio laser communications over a distance of 48 km
You can see the green Laser of DK5WMA Marcel and hear the demodulated telegraphy signal. The fading by humid air is clearly visible and audible. Unfortunately the autofocus of the camera does not like the dark environment.
The distance was about 48km between JO60LK and JO60MT.
