Subject: favor at Dayton?

I was supposed to go to dayton this year and made arrangements to go with a
friend from germany. As luck would have it, my job has required that I must
work and can't go. (side note: very angry about this, it's the 2nd year in
a row). I'm presently stuck in a hotel for 4 to 6 weeks on the road.
My question for the qroup is: Is anyone staying near the Super 8 who
wouldn't mind giving my friend a ride to the hamfest. It would save him
from renting a car, which I was to bring with me. Please contact off SIG
and I'll get him in touch with you.
Thanks
Wes

Does it work? Sort of. It is definitely NOT plug and play.
The Earthmates I'm somewhat familiar with output Rockwell binary data,
while the various APRS devices expect to see NMEA format data.
Byonics http://www.byonics.com makes a device called the GST- 1, which
converts Rockwell binary from the Earthmate into NMEA that can be
understood by trackers such as the TinyTrak.
If you are wanting to build a tracker and have some Earthmates, you can
read about the GST-1 at http://www.byonics.com/gst-1/index.html
and of course the TInyTrak3 with its smart beaconing and corner pegging
features gives beautiful bread crumb tracks driving around town as well as
on the open highway.

Many thanks for this detailed reply which I found extremely interesting
as well as being educational.
I will keep an eye on this and if I can find the originating station Ill
inform him of the clock problem.
Again, many thanks to those who replied.

My tnc lost its config, so I have to reconfigure it. Hence, my APRS was
not running. You couldn't get Keenan 'cause there weren't any digipeters
nearby. Nor were there cell phone towers much of the time, either.

Subject: Appalachain Trail
From: Bob Bruninga <bruninga@usna.edu>

More on my Appalachain Trial Project, but first a Travelog:
I was able to get a posit out from just about anywwhere along the 12 mile
stretch of the Appalachian trail this weekend. (washington Monument State
Park to Wolfsville rd, past Annapolis Rocks)(all in Maryland).
But my battery planning missed the mark, because we had not gone 100 yards
along the trail than I ran into a "radio" picnic table which appeard to
have some "official" capacity. On inquiry, there was a Marathon on the
trail and this was Checkpoint 6 along the way. The radio OP was someone I
knew 20 years ago from the AMRAD crew back when AX.25 was first develped
when we switched from RTTY to ASCII.
So, now, instead of turning my HT on for only 5 minutes for posits every
half hour or so, I left it on for the first 3 hours so that I could be a
"roving" APRS equipped trail monitor as the only HAM so equipped. Still
my D7 battery lasted the entire weekend. (and the second time I used the
GPS, I somehow put it back in the pack and left it ON, putting another 3
hours on its battery.)
The 10 minute suprise visit with the Checkpoint ops put my kids WAY out in
front and I was playing catch-up-elder for the next 3 hours. Adults and
kids all used FRS so each person could go at their own pace.
Good news is that at TWO places, I found perfect spots with AC power to
place one of my APRS trail kiosks. The first was in the shelter right
where these radio Ops were operating, the second was in the side yard of
the only house we passed along the way. A retired guy lives there and he
had placed a little garden along the trail with a weather-proof kiosk and
Sign-up log. I explained about my idea for an APRS kiosk and he said he
would be happy to supply it with power.
Hikers simply would raise the lid, type in their Initials and direction of
travel to identity themselves. This would update their Dead Reckoned
position. THey only answer one other question (hours remaining today) to
update their moving deadreckoned ICON.
See the concept:
A-Trail idea: http://web.usna.navy.mil/~bruninga/ham-trails.html
On initial entry into the system at any Kiosk they enter additional
information so that the APRS object will be more meningful:
Initials (XYZ)
Direction of travel (N/S)
Type of hiker (X) (THrough, Section, Weekender, or dayhiker)
ICON (hiker, scout, horse, dog, triangle (with overlay), bike, etc)
These are concatenated to form his UNIQUE hiker identifier (Callsign)
To this he can add additional information such as his starting point, and
destination and the usual 20 characters of free text.
From then on, think of it as a "flight plan" where APRS dead-rekons his
ICON along the trail to the next APRS Kiosk where all he has to do is type
in his "Identifier" and his posit and dead reckoning are updated. It
caontains a APRSdos map of the AT trail with all features included so
anyone can zoom in anywhere along the trail and find his fellow hikers.
Of course, This is only a dream. Ill have to wait to retire to find the
time to build the Kiosks. But the good news is that I have most of the
codw written and it runs on a single 1.4M floppy on ANY old
throw-away laptop (even without a hard drive). So there is little risk in
keeping the kiosks suppled with old monochrome laptops that loook GREAT in
the full sun...
Just someday...

Investigating. Further discussion moved to Xastir list.

I like your older hardware idea better, with the alphanumeric LCD. Not sure
how well those laptop screens will hold up to long-term UV exposure.
Terminals don't need to be any more complex than a KPC3. I think I'd have
the hikers pre-register on the website to get a numeric ID assigned so you
can use a small weatherproof keypad for data entry. Maybe even a barcode
reader. How about the ability for a hiker to pick up waiting messages at
any terminal, so those watching their progress can contact them?

How about a swipe card reader, hiker uses a drivers license or any available
personal plastic card with a mag stripe? That plus a PIC, plus a radio
could be a minimalist kiosk..

I can give you that in an 8 pin chip, coupled with a cheap "light pen" and
you're there.

How do you type in messages with a barcode pen?
