This makes sense.  Since rain drops fall vertically, pointing up would 
mean you are scattering off raindrops that are moving faster relative to 
the transmitter (and receiver for that matter).  This should push the 
pitch upward.  If the scattering volume were centered on the line 
between the TX and RX you shouldn't see any dopler shift.  Of course in 
reality, I would guess that there would always be a little doppler 
upward in frequency when doing rainscatter since it's nearly impossible 
to have rain drops that are moving away from the transmitter at any 
significant distance because the ground gets in the way.  Makes me think 
that doppler should be more in a storm with precipitation that falls 
faster (heavy rain/hail vs. snowflakes).  I'm hoping to have my 10G 
stuff running by August (1w to 18" dish) so I can play with some of this 
stuff...and bring it back to the cornfields of Nebraska every now and again.

Neato.
