It should always be ready.  I'm caching the data to make sure I can respond to 
google earth immediately.

If that station sent a non-position packet, it's position will be 0/0.  I don't 
return such stations in the KML because that would then place them in a 
non-obvious place.  Primarily this was done because it allows you to double 
click on the folder of the net-link and get a zoom to cover the area of all 
stations.  If you have 0/0 stations in there too, it shows you the whole planet.
