<div>That's a neat idea..... I have my wife's car's tracker set to change modes when the GPS is off. It changes from a car to a runner. There would be no difference in using a PIR motion detector in your ham shack set to a 10 minute on time tied to the mode change pin on a tiny trak or open trac.

<br>><br>> Actually, after Katrina, the ARRL made it an initiative to<br>> come up with a mechanism for determining and distributing the<br>> OPERATING frequency of all stations on the air, so that they<br>> could easily be found when needed. It is called WOTA for
<br>> "Who is On the Air". Since we have always encouraged the<br>> addition of Operating FREQUENCY as a standard field, we tried<br>> to make APRS a big part of that initiative. But I got little<br>> support. But we have now formalized a standard for including
<br>> FREQUENCY in APRS packets to improve this situation down the road...<br>><br>> What I want to see are PIC processors connected up to Home<br>> stations that will MONITOR the operating frequency of the<br>
> main RIG in the hamshack and automatically insert that<br>> frequency in that station's APRS *local* beacon.<br>> I do not want to see these beacons all over the state, but<br>> simply locally, so that if the need arises, that person can
<br>> be contacted.<br>><br>> In fact, I think it would make a nice set of Add-on's to many<br>> client software so that that software could monitor the<br>> stations other radios and include their operating frequencies
<br>> in that stations beacon.<br>><br>> IN fact, a TinyTracker or OT tracker or any PIC device could<br>> be made for the major CAT interfaces for Kenwood, Icom and Yeasu.<br>> Plug this device into the shack radios and plug it into an
<br>> unused HT on the APRS channel, and there you go...<br>><br>> Bob, WB4APR<br>><br>> > -----Original Message-----<br>> > From: <a href="mailto:aprssig-bounces@lists.tapr.org">aprssig-bounces@lists.tapr.org
