Hi Robin and all,

A great email thanks Robin, very interesting information. Unfortunately
using the 'coverage' url you kindly provided "NodeMobile coverage check
Coverage results.. Sorry, 3G service is not currently available in your 
area, however, we're continually working to expand our coverage. Please 
try again soon."  However, Optus are currently in negotiations with our
footy club, etc, to put their tower (Rah! A non-Telstra option at last!)
at the football grounds, being, as you'd guess, sort of central in town

This sounds an ideal solution thanks again Robin. Will be first in line
when Optus is radiating, and receiving, locally. Hopefully, fairly soon.

Cheers, Robin
Stephen Loosley
