This is a waterfall recording of off-axis rainscatter from GB3FNY. The thin vertical lines are reflections from a wind turbine 3km SW from here. FNY is about 20km south of me, the storms were to the SW as well. 600Hz doppler shift is about 10 m/sec or about 20 mph. Carrier frequency is at around 940 Hz. Interesting to see the frequency-domain pattern change with drop size, wind speed and rain intensity. Graph covers about two hours this afternoon, 24th August 2018. I am in IO93NR, beacon is in IO93NN on 10368.952 MHz
