Thanks to everyone who has replied to my enquiry re routing.

Given that my DigiNed digi (vk2tv-10) will become almost transparent 
when the remote digi is installed, I believe that WIDE1-1 is an 
appropriate alias.

As for the remote system for which I suggested WIDE2-2, I'm still not sure.

I seem to be missing something with regard to WIDEn-N routing and have 
been doing lots of reasearch to defuddle my brain. I understand how the 
SSID is decremented after each hop, but what yardstick is used to 
determine the initial numbers used for n and N?

Keith VE7GDH asked about the trend in VK re routing. The answer is I 
don't know. I enquired through some local APRS web pages but didn't get 
replies. But that's a bit irrelevent anyway because I'm more interested 
in doing it right, rather than doing it just because others do it a 
certain way.

Given that the first remote digi is still to be installed, much of this 
is hypothetical. If I start with WIDE2-2 and no other systems are 
installed, there will never be a problem. Even if a second system is 
installed, WIDE2-2 still can't propagate beyond that second system. By 
the time a third system is installed I'll be using a walking frame to 
carry out maintenance :-)
