Imagine the APRS map that day showing a clustering of mobile and portable positions all along the totality line. Please use the station symbol SUNNY (\U) for this event so these stations will stand out among all others on the national tracking page <a href="http://aprs.fi">http://aprs.fi</a></p><p class="MsoNormal" style="margin-bottom:12.0pt">In addition to this position reporting, APRS also supports real-time messaging. Not only will this be used by individuals for station-to-station texting, there will also be an announcement server that will give national connectivity for announcements. To use it, all one has to do is send an APRS message to ANSRVR and begin the message with CQ ECLIPSE… Such a message will be sent to every other station in the event that has also sent a similar message. Due to the load, limit transmissions to no more often than once every half hour.</p><p class="MsoNormal" style="margin-bottom:12.0pt">For other Ham Radio experiments during the eclipse please see: <a href="http://HamSCI.org">http://HamSCI.org</a></p><p class="MsoNormal" style="margin-bottom:12.0pt">Bob Bruninga, <a href="mailto:WB4APR@amsat.org">WB4APR@amsat.org</a></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> </span></p></div></body></html>
