<DIV><FONT size=2 face=Arial>Perhaps one of the smart guys that make TNC"s from
uP can include some search and replace code in the digi path ?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Add another option "Satellite SGATE
DIGI"</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Search for "SGATE" replace with "WIDE2-1" or
preserve the "SGATE" as well.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Maybe a satellite "robot" can be made like I did
years ago with a PIC chip</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>It listened for "SGATE" to come in on the serial
line , (ie satellite in range) and the TX for 10 minutes every minute then went
back to sleep.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Maybe we need to launch a satellite that "triggers"
ground stations, and then relays the list ? </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The ground unit could be considered a "transponder"
itself.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Maybe the sat could have some smarts and "POLL"
heard ground stations ?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Maybe the ground transponders could have a "lock"
light.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I see the ground device as being a simple radio and
a uP style TNC</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Just a few ideas.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The best satellite I liked was dove i thnk its was
?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Just straight packet down ?</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>What would be cool is a satellite that sends it
position LAT and LON.</FONT></DIV>
