Hi Liz,
I hope you have MY CALL = VK2XSE (you do not show a value against it in the
list below!).
My 2c worth.

I just took a little drive, and while I got packets to VK2XSE-1 and
apparently onto VK2RGF-1 (data from radios) none of them reached the
internet that way, just two packets which were received by VK2RGF-1 direct.
Obviously something on the radio at home isn't set correctly so I'm thinking
of getting the computer on the job as I understand its programming a little
Home Radio currently
Digipeat ON, my call
UIDIGI on, wide1-1, wide2-1
UITRACE on, wide
will try
UIDIGI wide1-1, wide2-2
as there are actually five or six hops to the iGates, just that the Wagga
linked repeater system only counts itself once.
