<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">The
Golden Packet team is toying with the idea of making our
annual Appalachian mountain digipeater string from Maine to
Georgia permament and making it a 9600 baud network for
emergency and ham radio disaster response and play. We
already have 3 of the 14 sites with approval for
installations…</span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Lets
face it, traditional packet networks are dead and although
APRS is alive and well, it is specific and only operates at
1200 baud. Although all fully integrated APRS radios work
perfectly well at 1200 and 9600 baud, all of the existing
APRS network is 1200 because all the digipeaters (not
integrated APRS radios) operate at 1200 and the majority of
all home APRS stations and IGates use TNC’s that operate at
1200. A huge legacy. Besides, going to 9600 only barely
doubles APRS speeds while degrading link reliability.</span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">So,
since we have already shown for 6 years now, that this long
2000 mile linear chain of mountains and valleys can support
a 2000 mile network with only 14 digis, why not establish a
long haul 9600 baud Node chain from Maine to Georgia which
could be a significant boost to Packet radio emergency
operations. The network would not operate as APRS
digipeaters but as KAnodes. As we all knew back in the
1990’s link-by-link acknowledgment was vastly superior to
end-to-end. </span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">We
already have three sites in MD, and PA … But we need more
than hikers, to get us access to some existing ham radio
maintained sites. We do NOT want nodes to branch off down
into the plains. These nodes would bog down the network.
No, the main backbone would be to support emergency
operations with beams that can point up to the mountains to
pass traffic.</span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">So,
we are splashing this onto the APRSSIG to see if people have
SITE access and/or have unused 9600 baud KPC-9612’s to step
up and lets see what we got. Also will need a freq. I’m
thinking 145.01 but every time I think of it, people give
feedback, and I LOSE or forget the feedback as to what
existing systems are already on 145.01, such as DX clusters,
etc…</span></p>

<p class="MsoNormal"><span
style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Every
day we get MORE AND MORE addicted to our wireless
infrastructure, which we all know, will be hard to access in
a real emergency. We need to keep the Ham radio Plan-B
alive…</span></p>
