I don't even know how to use the application... was hoping someone could help, that's why i gave gps points. new to 900mhz hardware... total n00b at this :shock:
yeah... place those points into Google earth... and then see the Terian.
The Bay Motor to AP has a 1,500 foot peak in the way. No way anything will work. Period.

The Bay Motor to NW has a 1,000 foot peak in the way. Nope...nothing will work either.
