Hi John,

Yes, I am familiar. My statement of implementing APRStt was not entirely accurate.

What I ponder is building a very weak transmitter (range under 50 feet) into a pill box with an Arduino (actually a Moteino). It would transmit on 915 MHz the racer id (bib number, sled number).

The receiver at the checkpoints would have a highly directional antenna perpendicular to the route. As a sled passed through the field, its bib number would be received, time-stamped, formated, and transmitted via APRS back to the operations center.

If I got fancy enough, I might "wake up" the sled unit when it was in range of the checkpoint. Filtering would be incorporated into the processing at receiver to capture only one report per sled at each check point.

This is to eliminate standing out all day in  near zero temperatures.

(All this is taking what a group in Tennessee did to the next level of integration.)

Very few hams have portable equipment for APRS but nearly everyone has a handheld radio that can send DTMF tones. APRStt allows a user, equipped with only DTMF (commonly known as Touch Tone) generation capability, to enter information into the global APRS data network. This document explains how the APRStt concept was implemented in the Dire Wolf application.

If you'd like to put a face to the callsign, just look for KJ4ERJ-12 on

I may also have my D72 with me, but may not have it on the whole time.

And of course, my car (probably) will be beaconing KJ4ERJ-11 from its

If the data were in error, I doubt that he would object.

However, the rest stops are double and triple checked prior to the event because they are based of the route instructions, which have to be printed days in advance.

Because some guy in a trailer at the command post may not be able to verify the location where the object needs to be.

See, this is where most people miss the concept that APRS is more than just mapping. It is situational awareness with input from all users, not just some guy in a trailer somewhere.

If the controller doesn't think the updated information is credible, he takes back ownership and puts the object back where it was. However, if the team at the actual location of the incident sees that the object is off, and they have the means with them to move it, they can.  The updated information goes out immediately and doesn't go through a delay to be updated by the controller.

But, you see, that is the whole purpose of having APRS objects to have situational awareness.. ANYONE that has updated information on an object can take ownership of that object, change whatever is needed to keep the object CURRENT and then transmit that information.

That way, it is not reliant on the original owner always updating the object. If the original owner wants the object back, he adopts and can then either keep the amendment or put it back. 

APRSIS32 does not support the adoption and transfer of ownership of an object. As such, if an object is updated by someone other than the owner, and object can appear to jitter between old location/information and new location/information. 

Permanent objects may be an exception, since they are permanent and not expected to change. Just my option on this last bit, I could be wrong.

I thought that APRS allowed for anyone to take ownership of an object and move it around.  So, you can have one (or some) instance of APRSIS32 create them, but any user should be able to move them as needed.  Everyone will then get the update, as you note.

You might still want to have the responsibility for object management centralized, but I don't think it's a requirement of APRS.

Re: A new observation prompts a new question [1 Attachment]

Hi Bob,
I slugged my way through the overlay thing a while back. I finally, and
with the help of several kind folks here, was able to hammer it into my
head. I used it several times to pre-fetch map tiles for an upcoming road
trip. Just about the time I got it down cold, however, googly maps dropped
the mapping feature that allowed the first stage of that process.
Fortunately, the race director provided GPX files of the course, so I was
able to get those overlayed. I have not yet tried to do the .POS files.

73, Ron (KC8SFQ)
++++++++++++++++++

As coordinator of some Half-Marathons for our RACES group, I've used
APRISce/32 to help keep track of our bike rovers on the course over the
last few years. Recently, through the help of this forum, I've learned
how to insert a .gpx overlay file to show the course route (very helpful).
If you don't already have this set up, I've attached a document that
details how to create a course in a .gpx file then insert it into the
program.


In the document, I have used sportrouteplanner.com website to create
the .gpx file. This site was mentioned in another topic in this forum a
month or so ago. Others may have other recommendations for creating .gpx
routes.


Once I inserted the .gpx file into the APRSISCE/32, I then followed the
wiki (again, thanks for help from forum members on this topic) for
creating and inserting a .pos file to overlay on the map in order to show
stationary checkpoints on the course.


Hope this helps.

Curious. In my experience, SAGs are rest stops at fixed locations.
Unless one will be re-positioning the SAGs during the event, what is the
value of equipping them with deaf trackers?

Probably two mobiles, deaf trackers in the SAG's. Two minute beacon rate
and time slotted just to be sure.

Re: Off topic - anyone used the Python APRS libraries

Now there is a potential security issue (SQL injection attack anyone?).

I'd really like to follow your work!  I was thinking about a similar application.  I was wondering if packet can pass SQL statements to update a database.  Custom application on each end.  I just don't have the time to dig into something like that.

Has anyone on this list used the python APRS libraries to build an application?

.

Looking to build a simple interface to transmit event participant data out of the mountains and have an application pick it up and put it in a database down in the valley.
