[Xastir] USRadar data

[Dale Seaburg]

Thanks for the USRadar maps. We will be using that when doing Storm 
Spotting.

I have a couple of questions:

  1. How frequently is the data - radar image - updated?  Every x minutes?

  2. When an update occurs, is the new image current, or is it "delayed" 
by x minutes, like WunderMaps from Wunderground?

Thanks again for this great service.
