But the message got to you via an SSn-N and your device/software is 
just acknowledging the message.  So if you're in a border area it's 
not going to propagate out of your SS so that's a good thing.  Or am 
I confused?  Which I probably am.

That said I can see border digi's responding to both, or more, SSn-Ns 
as well as WIDE2-2.    We've got one digi set  for that we for 
experimenting.   LLOYD with SK and AB. Trouble is that the nearest SK 
digi is not in reliable range of the LLOYD digi.    So I'm hoping to 
setup an intervening house digi at a relatives house in a village 
along the main highway which will work nicely.
