I know some of you have used APRS as part of the communications plan for
marathon and other foot race events.
I would like to know how you used APRS at these events.
I worked a 17 mile off-road foot race this past weekend and did not see that
APRS would have been of much value to the communications network.

Who here has used the VHF data radios from Maxon? I'm trying to get some

Did you have any kind of central "gathering place" for runners when they
came in and spectators? When we did the Shamrock Marathon in Virginia
Beach, Va, we had a start/finnish line/pavillon where we could put a LCD
projector. We projected the map on the wall, about 30' wide for friends
and family to see where the lead, tail end, support crews and any other key
movers were on the course. Worked very well. We even had trackers on the
pick up cars. Anytime there was a call for a pickup, at a glance we could
see which pickup vehical was closest to the drop-out. Streamlined the whol
operation.
My personal suggestion is, no matter the public event, if you look hard
enough, you can find a use for APRS.

Scott,
These aren't the VHF, but it's what I was able to find:
http://www.febo.com/packet/cheap-9k6/index.html
Our local University club (W5AC) bought these from Mr. Ackermann a little
over a year ago and began converting them from the voice version to the
data version, including building enclosures.
I can put you in touch with the folks at the club who are working on it
(besides myself) if you want.

Here is the top down priority list of how we use it:
1) Tracker on Lead vehicle
2) Tracker on tail vehicle
3) Tracker on VIP in charge and other VIP's
4) Trackers on SAG wagons and other important support vehicles.
That covers the logistics items.
Then for the entertainment value to the thousands watching, we used the
special APRSdos dead-reckoning version that allows all manner of humans in
the race to be tracked, without needing any RF trackers. It simple
dead-reckons the position of any special runner around the course.
TYpically then we add these moving objects to the race too:
Lead Female
The PACK
Lead Wheel chair
The Juggler (he juggles as he runs)
Any other easy to recognize runner.
These runners are transmitted by the APRSdos DR program and appear to all
OTHER APRS programs as if these runners had trackers on them. This lets
eveyrone see where these key "runners" are too. Only one person with
headphones runs the APRS-DR program and keeps objects updated with his
cursor as new reports come in. The progam keeps them moving...

Maxon has been absorbed into Tekk Radio at
http://www.tekk-radios.com
The data radios are at this page:
http://www.tekk-radios.com/Data_Radios.htm
including a link to a PDF spec sheet. Unfortunately they seem to be
listing only UHF data radios. Perhaps the special orders solicited on
the page might include a VHF version.

Subject: Re: [aprssig] 9600b UHF APRS IS THE FUTURE OF APRS
IMHO, no.
APRS succeeded because there was tons of 2 meter 1200 bps gear sitting
around about to be thrown away. When was the last time you used 2 meter
packet to check your email? APRS brilliantly used this cheap stuff to do
something new and amazing. I am one of the many that would not likely
invest in 9600 bps equipment. My pet peeve is that there is no 10 meter
FM 1200 BPS packet frequency. For rural areas *that* is the ticket with
plenty of surplus hi power "low band" commercial stuff available.

Subject: [aprssig] RE: Maxon data radios
Actually, Maxon America spun their sales group off to Topaz3. A few years
after that happened, Maxon America's engineering team was eliminated and
the group spun off to form SeMax engineering. The Topaz3 group remained in
business for some time after that and eventually was merged with Midland
Radio. As there web site is not going beyond the opening page for me today,
I can't say what remains of the Maxon line of radios. Tekk radios are not
the same as Maxon radios. They have many of the same features in common as
many of the employees worked at each of the companies. The Tekk company was
started from what I remember as some former employees of Maxon. If you look
at the older crystal radios, the multiplier chains are slightly different.
To answer your question, Scott, I have used some of the Maxon data radios
for APRS but it has been a couple of years ago and I don't remember how
they performed other than the 5 watt output didn't seem to make the grade
for me. Is there something specific that you are looking for, contact me
off list and I may be able to help.

Does it have to be 10 meters? 10 meters can get crowded when the band
opens up. It's bad enough that there's no "official" FM simplex channel
other than the calling channel.
How about 6 meters? BNSF Railway is doing some pretty interesting digital
stuff with a company called Meteorcomm. They are doing meteor scatter
communications on 44.58 MHz for monitoring hot box data and enforcing
"track and time" warrants for their GPS-equipped hy-rail vehicles. I think
Bob has talked about the possibility of meteor-scatter APRS in the past and
now there's a similar commercial application to prove it can be done
reliably.
(See http://www.meteorcomm.com/wireless/hlcs.aspx for the BNSF application.)
Just a thought... Of course, if you've been hoarding low band radios for
the lower bandsplit, you've got the wrong hardware and will need to start
hoarding upper bandsplit radios as well.
