Last week i took a screenshot of some RS signal on the local 10GHz WebSDR (http://microwavesdr.hopto.org:8901).
The picture shows the signal of DM0TUD with some strong rainscatter reflection with some doppler offset and frequency spread.
The spread and the shift are caused by reflection at falling raindrops during some local rain.
The clouds where high enough to give also some reflections from the beacons DM0UB (Berlin) and OK0EA (Prague) which can be seen as lines in the waterfall display.
