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
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 better.
Home Radio currently
Digipeat ON, my call
UIDIGI on, wide1-1, wide2-1
UITRACE on, wide
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.
