[NLRS] Rain Scatter today

[Donn Baker]

Good show, guys.

But remember, too, Bob, that you don't have a "zero-degree" horizon.  If
you'd been able to operate from, say, Ridgway Park you WOULD have had the
0-degree horizon, and a correspondingly longer range.  Geometry is
everything... wish I'd paid more attention in class !
