For those that did not have a chance to track Sunday's 26 mile marathon
I'm enclosing a word picture document of the 30 second reports by the
lead bicycle (see below). This was the result of a three week crash
program to come up with a system to track multiple APRS units in one
event without packet collisions through a process of time-slotting. Two
new digipeaters were installed at La Cumbre Peak and La Vigia Hill. In
addition, the packet positions were fully available within a couple of
seconds on the worldwide web. All packet reports of this event are kept
in storage by for a period of time if anyone is interested in looking at
the total packet picture. I am resending Shaw Takeuchi's email about
using aprs.fi.
A great deal of thanks go to all the individuals who played a big
part in pulling this packet reporting system together. The APRS packet
system on 145.63 will remain intact for future events.

I keep seeing web posts saying “click on aprs.fi” – which will either
take you to somewhere out of USA by default, or sometimes displays Los
Angeles area (don’t know why). You can send people ‘links’, make
bookmarks, or create shortcut on your desktop with the following URL
parameters to make your life easier:
Example 1: Show all stations in 93111 zip code area w/ zoom level 13,
last 15 minutes only -
http://www.aprs.fi/?addr=93111&z=13&timerange=900
Example 2: Same as Example 1 using different overlays -
http://www.aprs.fi/?addr=93111&z=13&timerange=900&mt=m
http://www.aprs.fi/?addr=93111&z=13&timerange=900&mt=k
http://www.aprs.fi/?addr=93111&z=13&timerange=900&mt=h
Example 3: Track and show KI6WEL only w/ zoom level 14 –
http://www.aprs.fi/?call=ki6wel&z=14
Example 4: Track and show N6OLT only w/ zoom level 14 –
http://www.aprs.fi/?call=n6olt&z=14
Note the last two examples will ONLY show your target call-sign movement
– all other trackers, WX in the area are NOT shown (which could be a good
thing on a congested map).
This link describes how to control your initial views such as zoom
level, center lat/lon/zip, set history time, set map types, etc.
