Ah, I'd like the IP address you are PINGing. What do you type
after the command "ping"?<br>

</div>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Scott Honaker and I have moved forward
on this project:<o:p></o:p></p>
<ol start="1" type="1">
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l4
level1 lfo5">We have installed a gateway (Linksys
BEFSR41) between the ID-1 and the internal ARES/RACES
subnet (not 44.x.x.x) of the DEM.<o:p></o:p></li>
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l4
level1 lfo5">We have installed a Digi "AnywhereUSB" box
to give us remote access to the ID-1's USB port, and
thus remote control of the ID-1 radio. This not only
allows multiple use of the ID-1 (which has useful 1.2GHz
FM and digital voice modes as well as Ethernet data),
but provides for remote frequency agility and a
diagnostic capability. This works beautifully (eg, to
search for and use a low-noise frequency)!<o:p></o:p></li>
</ol>
<p>Unfortunately, what does not work very well, is the RF
portion of the connection. PINGs failed at a rate of over
99% when using the 1.2GHz antenna at the 70 ft level on
the tower, so we swapped the antenna with the one used for
the Icom 1.2GHz repeater (which wasn't seeing any action
anyway) at 100 ft. That made a "dramatic" improvement, as
PINGs now only fail at a 98% rate (depends upon the time
of day, etc)!<o:p></o:p></p>
<p>Antenna comparison between 1.2GHz and 5.9 GHz for the two
sites:<o:p></o:p></p>
<ol start="1" type="1">
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0
level1 lfo8">On 1.2GHz, both antennas are
omni-directional.<o:p></o:p></li>
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0
level1 lfo8">At the DEM, the 1.2GHz antenna is now at
the 100' level, whereas the 5.9GHz antenna is at 150'.<o:p></o:p></li>
<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0
level1 lfo8">At my home, the 1.2GHz antenna is about 10'
above the 5.9GHz antenna, and it's on the same
line-of-sight path.<o:p></o:p></li>
</ol>
<p>Note that voice communication between the two sites using
the two ID-1 radios, is fine (there is a slight bit of
noise on FM).<o:p></o:p></p>
<p>The big difference, in my opinion? I'll bet that the
wireless protocol used by the MikroTik radios includes an
aggressive error correction and retry protocol, whereas
the ID-1 is like a piece of Ethernet cable, and thus
relies on the standard TCP/IP retry mechanism. The TCP/IP
protocols, while "unreliable" in the technical sense of
the term, require a higher overall reliability than a
typical raw wireless connection.<o:p></o:p></p>
<p>What this says (and I'm a bit surprised to note this), is
that sites considering using ID-1 radios for data
communications, may find that even with the tighter siting
requirements of 5.9GHz, that the latter may be more
successful (whether or not part of HamWAN). In addition
to being a lower-cost radio with a much higher data rate,
the MikroTik radios offer a built-in router, which can
obviate the need for a separate router.<o:p></o:p></p>
<p>-- Dean<o:p></o:p></p>
<p style="margin-bottom:12.0pt">ps: The callsign and digital
code filtering features of D-Star that we previously
discussed, are not available (greyed out in the software)
for digital <b>data</b> mode. Huh? Another fine example
of software of the "seven last words" of poor program
design: <b>"Why would you want to do that?"</b><o:p></o:p></p>
