[aprssig] APRS data dump for a month or two

[James Jefferson Jarvis]

Go ahead and grab it all as fast as you can! That machine is on an internet2 
connection, so it has way more bandwidth than you have :-)

There appears to be about 4.9 gigabytes of position data going back to 
December of 2003. That's in gzip -9 form, so expect this to use a lot of disk 
space. Probably at least 50 gigabytes. :-)

I would imagine that by looking at all of that data you'll get a pretty good 
picture of what APRS coverage is in California. It might even be neat to make 
some graphics and show how APRS coverage has changed over the last two years.

I'm not aware of anyone that has a long term database of every single packet 
available for use. I purge my raw packets fairly regularly and my position 
data gets purged at least every 6 months.
