tracker</DIV>
<DIV><BR></DIV>> I revisited an old project tonight.<BR>> 434 MHz TX and
GPS, easy radio module.<BR>> Sending: <BR>> <BR>>
VK4TEC-12>APRS,WIDE: <<UI>>:=2734.45S/15306.21E'SATS 03<BR>>
RAW,27344551,S,153062152,E<BR>> <BR>> Takes 76 ms on busy pin, or
44 ms of actual data.<BR>> The down side is the power out is only low,
mW<BR><BR>Actually that is perfect! And all you need to send
is:<BR><BR>"VK4TEC"<BR><BR>Which drops it to 4ms of data. AND then the
RECEIVING device<BR>which is located at the door of the clubhouse, EOC, ham
radio<BR>store, local bar, church, jail and everywhere else in town
where<BR>hams might be found adds the following
info:<BR><BR>LAT/LONG<BR>SYMBOL for RFID tag<BR>Local RF Voice Channel at that
location<BR>Comments about that location<BR><BR>And then sends that packet out
on the APRS channel like
this:<BR><BR>VK4TEC-12>APRS,WIDE1-1:=2734.45S/15306.21E'147.105MHz AARC
Radio<BR>Clubhouse<BR><BR>But the hundredths digit of LATITUDE is randomized
so that<BR>everyone at that location will appear as a list at that
location<BR>and not all on top of each other.<BR><BR>Please see the APRS RFID
web page:<BR><A
href="http://www.aprs.org/aprs-rfid.html">http://www.aprs.org/aprs-rfid.html</A><BR><BR>Put
this in a Key Fob and all a Ham has to do is push a button<BR>and he
instantly is seen globally, whwere he is, what he is<BR>doing, and what
frquency to contact him on.<BR><BR>Go for it!<BR>Bob,
