I have live on-line maps showing APRS activity, as monitored off-the-air in central Michigan. Separate maps show ONLY off-the-air RX on 2-meters, , the ISS digi, 30-meters HF and 60-meters HF -- not the Internet feed. Go to:<o:p></o:p></p><p> <a href="http://WA8LMF.net/map"><http://WA8LMF.net/map></a> <o:p></o:p></p><p>to view the various mapping webservers. Actually one display does show the Internet and off-air reception combined. The map called "2 Meters VHF" shows the off-the-air RX only. The one called "Special Events Webserver" uses the identical map image, but shows off-air and APRS-IS Internet feed combined. It's a dramatic demonstration of the diversity receive effect of combining multiple receive sites via the APRS-IS vs a single receive site. <o:p></o:p></p><div class=MsoNormal align=center style='text-align:center'><hr size=2 width="100%" align=center></div><p style='margin-bottom:12.0pt'>Stephen H.
