[Robbie - WA9INF]

I have set up a web page to track my car and the aprs activity within 50 
miles of my travels. Experimenting before a trip..

Now the reason for the post here, is to ask, how long do the nearby 
stations persist after they become out of the filter range, or the 
mobile has shut down? I am using a filter of f/wa9inf-1/50 and it has 
been working really great...

So far, it seems after I shut my mobile down, the stations remain past 
24 hours.. I think that is fine, but just curious for referrence..

Pete??
