Ah, ok.  I had changed it to the max (60min) to lessen the load on the
system, since my info doesn't change much.  Guess I went too far.

Ok, found that.  But, there are three options in the next frame down
that are currently not checked:
  - Transmit compressed objects/items
  - Activate Alternate Net
  - Disable posit dupe-check
I assume I leave them off?

There is also a field for typing in a string, but it's not labeled.
What goes there?  Currently is says "XASTIR".

I guess I'm skeptical about how much value this would have, since I
live in a bit of a hole.  We're by a creek, so by definition I have hills
on two sides.  The antenna currently is a twin lead Jpole hanging
on the wall in the shack, on the first floor of the house.  Height above
ground is maybe 8', depending on where you measure to.  Height
above the street level is about zero (the lot slopes down).  Power is
5 watts.  There is a good digi and igate 21.3 miles from here (K6FGA-1)
on Banner Mt.  Fortunately, it is down stream, so I can hit it reliably.
Is adding my little 5w station to the RF clutter a benefit or just more
QRM?

I guess the program knows where on the Internet to aim the traffic,
as I see no place to configure it.

One more question:  A number of the postings related to old vs new
addressing (wide vs wide n-n) talk about needing to upgrade the
hardware (TNC, presumably).  Is my MFJ TNC ok, needing new
software, or does this even matter when using XASTIR?
