 Then I learned about the messaging and weather components of APRS, and it started to look useful, not just fun!
-Be warned - learning about APRS can be a lot like drinking from a firehose. There are trackers to understand, RF infrastructure to look for or build, an Internt component that vastly extends the RF infrastructure, and lots and lots of websites with often conflicting (or seriously out of date) advice.

-The basic things you should know: APRS stations periodically send packets with information about their position or other status. Those packets are (hopefully) heard by digipeaters, which repeat the packets to get them heard over a wider geographic range. ARPS stations can be stationary or mobile: hikers, cars, truck, boats, planes, even the International Space Station!

APRS stations can be stationary or mobile: hikers, cars, truck, boats, planes, even the International Space Station!
 That was the end of the original concept; people hooked up packet stations and watched the activity on their computers and, eventually, on specialized radios like the [[Kenwood TM-D700]] [[http://www.eham.net/reviews/detail/1118 1]], [[TH-D7]] [[http://www.eham.net/reviews/detail/1332 2]], and the [[HamHUD]] [[http://www.hamhud.net 3]].
-Eventually, someone got the idea to connect an APRS packet station to the Internet. That makes it possible to watch, track and communicate with ARPS stations pretty much anywhere in the world, not just within a couple of RF hops. (I recently exchanged text message traffic between Fresno Dome and Oslo using my [[TH-D7]] handheld.)

 If any of that sounds like fun, then APRS might be for you. If you have an old packet station, you can get started right away.  The basics of getting a glimpse of local activity is captured in a very nice article by Richard Parry, W9IF, on the ARRL website [[http://www.arrl.org/tis/info/HTML/aprs/pos-reporting.html 4]].  Even if you just have a connection to the Internet, you can get involved.

 Which leads back to "why?". It's kind of fun to put a tracker in your vehicle, at least if you're of a certain bent. It might let your OM or XYL know where you are when you're out of repeater/cell phone range. As you drive around, a rig like the [[TM-D700]] or [[HamHUD]] will let you see what other APRS activity is nearby, including what repeaters are good to use nearby. SAR teams use trackers and APRS to manage rescue efforts[[http://wetnet.net/~we7u/search_and_rescue.html 11]].  If you carry a [[TH-D7]] with you while hiking or climbing, you can get local weather information and send email!
-People continue to come up with new uses: high altitude balloon pilots use APRS for tracking and recovery. Distant repeaters can transmit telemetry and receive control commands. Many government agencies post earthquake, flood and severe weather alerts via APRS objects.

 But a great place to start is the way many people seem to: connect an [[OpenTracker]] [[http://n1vg.net/opentracker/ 12]] or [[TinyTrak]] [[http://byonics.com/tinytrak 13]], a [[GPS]] and a 5W HT to a mag-mount antenna on top of your car or truck, and drive around with it for a while. See if it's useful or at least fun, and then decide if you'd like to go farther with this aspect of the hobby.

-In addition to the sites and mailing lists mentioned there, you should be aware of http://www.findu.com and http://aprs.he.fi, which will let you look up individual stations or watch all the activity in an area, without any software except a web browser.

-For example, start with http://map.findu.com/okhrst or http://aprs.he.fi/?call=okhrst to get a peek at what's going on with APRS around Oakhurst. (You'll want to click on "stop tracking" in the aprs.he.fi popup box.) Those two websites will provide you hours of fun just by clicking around. (If you use dialup, you may find these a bit challenging.)

 Those sites, as well as programs like [[Xastir]] [[http://www.xastir.org/ 5]], [[UI-View]] [[http://www.ui-view.org/ 6]], [[WinAPRS]] [[http://www.winaprs.org/ 7]] and many others [[http://www.eskimo.com/~archer/aprs_capabilities.html 8]] will let you see what activity is being reported via the APRS-IS system [[http://www.aprs-is.net/ 9]] - that is, the Internet side of APRS.  If you add a TNC and radio to your computer, you can watch the RF activity as well - some of it probably doesn't make it to APRS-IS.  If you're in a good location, you can help fill in a coverage gap with the same software!

 However, if you look at the local activity, you'll see that there isn't much. That's partially because, until recently, there has been no APRS infrastructure (no digipeaters) around Oakhurst. Jeff KF6CNV and Chris K6DBG have been working to change that - there is now pretty good coverage along 41 and 49 through our valley, and more to come[10]. Now that packets are getting out, we hope to attract some users.
