[NLRS] Rain scatter and doppler shift

[Andrew T. Flowers, K0SM]

Scott,

With the storm between the two stations you'll have some spreading of 
the frequency depending upon how turbulent the cell is, but the main 
contributor to doppler shift in that case is wind that is perpendicular 
to the radio path.  When working backscatter you will have much more 
significant frequency translation and spreading because the storm is 
moving toward (or away from) both stations at the same time.  From my 
experience SSB is pretty useless on backscatter paths anyway.
