![]() "J. Severyn" wrote in message ... Thanks!!!! This APRS system is outta-sight. As a retired EE, I've toyed with getting a ham ticket since I was a kid...and this might just do it. This has wide coverage....and does not depend on a G-switch like an ELT.....even the new 406MHz units depend on a G-switch to trip if the victim cannot trigger the unit manually. I like the continual tracking feature.....just look where the signal stopped. I've spent some time in the past half-hour and understand the electronics. But has someone put together a small transmitter with an embedded GPS, to make the whole unit a "one box" solution? I have no problem building a APRS transmitter myself, but it seems a single small package has a better chance of always being in the plane, say mounted on a door post or under a glass turtledeck. Maybe with a rechargable battery, external power plug (to keep it charged from the ship's power). OK..... tell me more. What class ham license do I need? John Severyn KLVK Livermore, Ca. wrote in message ups.com... Fairly simple. The (2m) tracking unit has a small gps that feeds digital signals to the attached transmitter. The signals include latitude, longitude, speed, altitude, direction and are picked up by a host of volunteer ham towers - digital repeaters and/or iGates. That info is transferred to internet servers and you can easily see the results on a Google (or other type) map on places like www.findu.com - simplicity itself for users. I suggest that you pay another $15/yr for a private website YourPlaneName.com where your relatives or FAA can go to find the latest tracking. A lot of automobile users use the system so their wives can tell where they are (hmm?) . But their signals are often blocked by terrain. The best performance is from aircraft - any ham digi or igate tower within couple of hundred miles can see the signal. I have flown cross country - remote areas - and there is rarely a break in 1 or 2 minute reporting intervals. Are you still gawking around. Memorize answers to some 100 ham questions, pay the $20? fee and get a APRS tracker. It may save your life. Check out these folks: http://www.byonics.com/ In particular: http://www.byonics.com/microtrak/mt8000.php You only need the Technician license. Details at www.arrl.org Lots of study guides are available on-line. |
