race and net control and other fixed locations. Mobiles transferred to
provided vehicles mostly run basic transmitter only trackers
co-ordinated with net control, etc. They are connected with the transferred radio to
the vehicle battery, leads secured with "duck" tape, use mag antennas,

<div id="yui_3_16_0_1_1439231958724_196060" dir="ltr">I have been reading all the replies to your question with interest, but kept coming back with a question of my own...why?</div>
<div id="yui_3_16_0_1_1439231958724_196078" dir="ltr">(For some background, for the last 10 years I have been involved with the ADA Tour de Cure/Chicago bike event, the last 5 as Communications & Safety chair)</div>
<div id="yui_3_16_0_1_1439231958724_196082" dir="ltr">You didn't explain, but I am guessing that your SAG vehicles will cover pre-determined areas of the course, and that you have a net control operator(s) that are coordinating operations. While it is a nice idea, if it was me...I want my ops keeping situational awareness of what's going on in their area (i.e., what's happening outside their vehicle). They really don't need to know what's going on over the rest of the course- that's the job of net control (and whoever may be helping them). You are really adding more complexity than necessary to their job. They can't be watching for issues if they are studying another screen...</div>

I've used AvMap, WinBooks, Bluetooth TNCs, and soft TNCs. All have their merits, but if you're looking for something that will be less expensive to procure for multiple assistance vehicles and rest stops, I'd recommend simply hooking an Android tablet or phone via audio cable to a HT. The app APRSDroid has a connection protocol labeled "AFSK via Speaker/Mic" that will decode the received packets heard on the radio and overlay them on a map on the Android device's screen. The option to use an Offline Street Map is there and with the device's built in GPS, you know where you are in relation to the objects that you're receiving. </div><div class="yiv8979615163gmail_extra"> </div><div class="yiv8979615163gmail_extra">Simple. Inexpensive. </div><div class="yiv8979615163gmail_extra"> </div><div class="yiv8979615163gmail_extra">If you wanted to transmit, too, I'd recommend a more capable radio than a HT, but it sounds like you're just trying to bring situational awareness to more people. That being the case, the wattage of the device is irrelevant. Depending on your peer group, it's not hard to find people who have an older Android device gathering dust in their home from the last upgrade cycle or two. That leaves your cost at $4.99 for the app and whatever money you spend making cables. I'm assuming finding HTs and mag mount antennas to borrow will also not be a problem within your local club.</div><div class="yiv8979615163gmail_extra"> </div><div class="yiv8979615163gmail_extra">This setup that I'm describing is the entry level APRS rig that we use to get new amateurs in our club exposed to APRS. After they use it for a few weeks, they tend to upgrade to something with more transmit power. However, for your purposes, it may be ideal.</div><div class="yiv8979615163gmail_extra"> </div><div class="yiv8979615163gmail_extra">Here's the "how-to" we wrote for our club.

We have an ad-hoc network to support our trackers over the course area. I have been turning my attention toward broader use of the info.

For insurance purposes, the bike club provides the cars and drivers. The radio op rides shotgun, using a Go-Box that has battery assist so that the cigarette lighter adapter isn't doing the heavy TX lifting and can be shared for other uses.</div><div><br clear="none"></div><div>I'd like to have simple, non-transmitting display setup so that the operator can "look" around the course as he has need. I'm not sure where to start looking for commercial solutions, if there are any at all. I also have been wondering, given the abundance of R-PI hardware, if a R-PI and display would be enough to run something like YACC. A simple RX and antenna would be enough, and the package could be small enough to occupy little of the precious space in the vehicle and not pose a safety issue. Even nicer if it could be on the dash.</div><div><br clear="none"></div><div>So, what do you folks know?
