</font>Hi Grant,<br>
<br>
<font face="Arial">I was using a Tiny-2 with DCD option on 145.825
for aprs satellites<font face="Arial"> and <font face="Arial">86
days</font> ago (current uptime) I changed to a<font
face="Arial">n Odroid C1+ running Direwolf</font></font></font>,
and I'm now decoding between <font face="Arial">two and three
times the number of satellite<font face="Arial"> <font
face="Arial">transmisions, this using the same radio, a
Kenwood TM-V71A. The Raspberry Pi is also a suitable
computer but I chose the Odroid because it has a RTC on
board and a battery backup option for it.<br>
<br>
<font face="Arial">Direwolf does something a ha<font
face="Arial">rdware TNC can't do, it compensates for
signals that are over or under deviated and signals with
grossly incorrect pre-emphas<font face="Arial">is</font></font></font>.

<font face="Arial">I'm surprised Glenn didn't try to talk
you into using Direwolf and an Odroid (;->) <br>

<p class="MsoNormal">Folks,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It has long been an idea of mine to see a
high site digipeater on the top of the Adelaide Hills around
Mt Lofty / Crafers / Summertown to provide broad area metro RF
coverage. Adelaide has many I-Gates but the one RF digi we
have for the Adelaide plains isn’t well sited for that role
(VK5RHO) and coverage in the Western and inner SW/SE suburbs
has been poor since VK5TTY lost it’s site a few years ago.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">An opportunity has now arisen to install a
machine at the long time licensed but never activated (on
APRS) VK5RSB site at Summertown using the VHF antennas that
have now been installed for the temporary VK5RAD 2m repeater
(while it’s tower was being refurbished). <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks to Glen 1XX I have obtained a TAIT
radio. I have also dug out of the old SAPUG stores the Tiny-2
TNC that used to run the VK5RAD ROSE node which has a DCD
State Machine built in (allowing open mute operation). <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, before I glue the hardware
together in a case, I would like some suggestions please on
the following:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

style="mso-list:Ignore">1)<span style="font:7.0pt
"Times New Roman""> </span></span><!--[endif]-->If
I stick with the Tiny-2 TNC what EPROM software do people
suggest is best for APRS these days? (version, download source
etc please?)<o:p></o:p></p>
<p class="MsoListParagraph"><o:p> </o:p></p>
<p class="MsoListParagraph"
style="text-indent:-18.0pt;mso-list:l0 level1 lfo1"><!--[if !supportLists]--><span
style="mso-list:Ignore">2)<span style="font:7.0pt
"Times New Roman""> </span></span><!--[endif]-->If
I don’t stick with the Tiny-2 (depends on how serviceable it
is) what alternatives do people suggest for the digital side
that are bulletproof and fit the KISS principle?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The site will be a plain WIDE2-2 digipeater
– no internet connectivity. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
