<div dir="ltr"><div>A couple of "Way back..." APRS examples.</div><div>Around 2000 or so, a local business acquired a bunch of OTS ham TNCs (forgot make) that had built-in APRS functions. He installed them in his delivery trucks connected to his business-band commercial radios as trackers. With a TNC connected to the base station in his office, he had a map displaying the instant location of all his delivery trucks. This was at a fraction of the cost of commercially available vehicle tracking products available at that time.</div><div><br></div><div>Around 1999, I met a commercial OTR truck driver on 146.52 coming across New Mexico. We met up at a rest area and he showed me his APRS setup. He had a custom control head that showed his position and beacons from other APRS stations. It was a small box with a dot-matrix type display of about six lines. He had a set of status buttons that beaconed driving, out of truck, and a few other canned messages. It also had a small thermal printer that could print out messages. He said his wife (Technician licensee) could send him a message and it would bounce around through digipeaters and print out in his truck. He said he had it all hooked to a computer at home his wife could look at any time and see exactly where he was at.</div><div><br></div><div>I am still hoping to get my APRS system fully functional with similar quick status buttons and other easy features in my vehicles. I already have my base configured with a large display showing only local RF based data 24/7. All the fancy Internet sourced fluff (airplanes, boats, non-ham weather, etc.) is of little interest to me in this particular application.</div><div><br></div><div>Michael WA7SKG<br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Oct 22, 2020 at 5:09 PM Robert Bruninga <<a href="mailto:bruninga@usna.edu">bruninga@usna.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr">Someone asked me for a quick summary of APRS and I had no answer.<div>There is so much written it is a tidal wave not just a firehose.</div><div><br></div><div>But I did point him to this page which I wrote years ago as a summary </div><div>of what most people simply overlook in APRS.</div><div><br></div><div><a href="http://aprs.org/APRS-tactical.html" target="_blank">http://aprs.org/APRS-tactical.html</a><br></div><div><br></div><div>It is a good thing to revnew now and the.
