John, thanks.
You're right....  the 30 vs 28 wont filter the crazy moving mobile.
And glad you are trying SSn-N.  The neat thing about it
is that a digi can try SSn-N without any impact on WIDEn-N if he
wants by just swapping it for UITRACE.

Thought the whole advantage of it, however, is in actually getting
rid of the WIDEn-N that is presumably brining in too much junk.

Hi Bob,

I'm not sure that this is really the way to go (verses

Some thoughts leap to mind.

1) I believe that Marco's code looks for "exact" dups;
which of course a mobile tracker will not give. No
match, and it's repeated.

2) Remember that we have on 32K of RAM to play with, and
a lot of that is gone for the base code, and other buffers;
So, for a busy digipeater, extending the time, may cause
additional grief. (I'll look into this one further, once
the holiday are behind us.) I think it's FIFO, but I'd
like to run some tests before making any statements.

We're also testing our a "LAN" for the big machines in
S. Ontario. We're using "SONT n-n" to see if that improves
things. ("We" being Phil VE3RD and myself, BTW.)
