[HamWAN PSDR] Questions

I discovered a clever technique for initially orienting the antenna:  
Using Google Earth, I draw a line from the Node (in this case the DEM 
antenna at Paine field), to my house (5.02 miles 149.89 degrees).  No 
only does that give me a pretty good initial bearing (300), but I get to 
see what obstacles are in my way (it isn't pretty) for various 
prospective antenna locations.  So, I see I'm squarely in the DEM SE 
(60-180 degree) sector.

Which brings me to my next question:  Where is this "scan list" and 
where do I set it?

Is there a way to configure the radio to get the date/time from a local 
NTP server?  That would make its logs a little more meaningful ...
