How are these stats collected?     Do these numbers reflect stations 
heard from RF and igated, or stations actually themselves connected to 
the IS?    Or both since the default would be for the IS to contain both 
Internet-only and RF-gated-to-Internet stations.  


I ask since I am puzzled how APRSdos shows up at all since it lacks 
Internet connectivity.   I assume this must reflect APRSdos stations 
heard over RF by an igate.
