                  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>

                  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>

                digital code filtering features of D-Star that we
