[Xastir] faster radar image updates?

[Richard Polivka, N6NKO]

The DOW (Doppler On Wheels) trucks have been using the phased array 
systems for some time and the results are fascinating.

Yes, bandwidth issues are going to be the bottleneck. With the poor data 
comm infrastructure that we have here in the States is going to be a 
killer to getting these services online and available for usage.

It would be great if there was symmetrical 100MBit/sec DSL available but 
I don't see the telco companies doing it anytime soon but that is 
another story all together.

73 from 807,

Richard, N6NKO
