<h3>Usage Instructions</h3>
<p>When in range of MB7VX, send APRS packets on 144.800MHz.</p>
<p>To enable RF-to-RF communication locally, MB7VX may be used as a digipeater.
It will digipeat packets according to the "new n-N Paradigm". In practice, this
means that you should set your path to include at least "WIDE2-1" or at most
"WIDE1-1,WIDE2-1".</p>
<h3>Coverage</h3>
<p>Reports are encouraged and should be sent to <a
href="mailto:irl@hambsd.org">irl@hambsd.org</a> with the subject line "MB7VX
Report".</p>
<h3>Station Details</h3>
<h4>Controller</h4>
<p>While HamBSD matures, this station is currently controlled by the firmware
of the transceiver.</p>
<h4>Transceiver</h4>
<p>MB7VX uses a Kenwood TM-D700 as its transciever.</p>
<h4>Antenna and Feeder</h4>
<p>A resonant feedline dipole is installed on the roof of the building.</p>
<p>22 meters of RG58 coax is used to connect the antenna and the radio.</p>
<h4>Internet Gateway</h4>
<p>A fixed-line internet connection is available at this site, but is not
currently used.</p>
