[aprssig] Appalachian Trail Golden Packet Event update

Bob,

I've been following along on your efforts for this event, and it certainly sounds like an interesting project, but I'm not sure I understand the goal.

The stated purpose of this:
PURPOSE:  To field enough 
amateur radio emergency communications teams on mountain peaks in The Eastern USA
to be able to communicate 
packets and APRS messages
 from end-to-end of The Appalachian Trail.


But the planning that goes in - and the back-channel communications links to allow coordination - make this seem more like a lab experiment than a practical communications system.  

Is the eventual goal setting up an alternate APRS net along the Appalachian Trail using self-sufficient devices?  Or is this just something to demonstrate that with intricate planning and coordination using existing communications methods an APRS network can be built to deliver a message 1200 miles away?

I apologize if this sounds rude; I'm just trying to understand if this is a precursor to something else or just a one-time demonstration.

Thanks,

Kevin

Good news - Bad news - Good news!
AT Trail Golden Packet Planning:
 
The good news is that the silo on the tree covered hill called
Governor Dick Hill in SE PA is not a silo, but is a public
Observation tower!  Piece of cake for operating (after climbing
the 60 feet of 8' vertical ladders between landings.  
See  www.aprs.org/hamtrails/GD-hill.html
 
The bad news is that there are no driving roads to the tops of
the WV mountain station and the mountains are covered in tall
trees..  But the good news is that we found a rock outcroping
called White Rock Cliff that can see both links NE and SW and so
we no longer have to hike-up a 60' mast!  
See www.aprs.org/hamtrails/WV.html
 
Each of the 15 stations now has its own web page and cross links
between them all, so you can move up and down the trail to see
how the project is coming.  The main page is still:
www.aprs.org/at-golden-packet.html
 
This event on Sunday Afternoon 26 July should be lots of fun for
APRS and packet and VHF
folks that like to get out into the great outdoors.  We will
also have voice comms, and an echolink conference for mountain
top coordination over all 2000 miles of the trail!
