<div class=Section1>
<p class=MsoNormal>We have been working on our local very active Search and
Rescue group to start utilizing APRS more for tracking. Some questions
have come up and I was wondering if there were some people who have already
done this stuff:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>1)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>They want to utilize much higher beacon rates on
Mobiles/Portables. To allow for good tracking during a search. The
portable digi (like a d700) will only beacon once per 10mins locally to keep it
legal.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Due to the increased beacon rate (proposed 2minutes) we
think we should maybe use APRSALT frequency of 144.990mhz (it is available in
our area).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My main question is if we utilize 144.990mhz can we somehow
get these people out on 144.390mhz without causing tons of traffic
problems. If I had an igate on 144.990mhz via a 3G network could I then
have the local IGATEs send out on 144.390mhz the callsigns but only like every
10 minutes? Could I use a KPC-4 (dual port 1200bps) or something else to
digi between 144.990mhz and 144.390mhz every 10mins for each station with the
right UIDWAIT?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Should we consider using 9600bps and increase our TX rates
to 1.5minutes? Then I could digi between 144.990mhz on 9600bps and
144.390 on 1200bps, but again it would be too much data. I need to
control it with UIDWAIT or something?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks for any suggestions.<o:p></o:p></p>
