It's actually the whole NE coastline in Queensland, from Brisbane all the way up north to Cooktown. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Queensland is supposedly better where it's served by Energex but even if you asked a lineman in Brisbane it might be all nice and dandy there while it's very different up north. However, I did ask my client to request info via their Australian people. BTW, the poster in the AU group measured the current voltage and got a reading of nearly 258V (!). -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
