Here is the annual 2009 update on the state of the APRS
digipeater network.  It shows much better penetration of the
New-N paradigm and the optimum "S" digis...

New-N-Paradigm Digis change from Jan 2008 to Jan 2009

 S digis 1342, was 1400 New-N's that support SSn-N 
 L digis  100, was  130 Limited New-N's 
 F digis   18, was   32 KPC3 old ver 8.2 FLOOD only
 P digis   10, was   35 New-N   Paccomms 
 1 digis  198, was  180 New-N   one-hop digis 

Obsolete digis:

 N  308, was 520  Old -N's that flood and bad timings
 T   50, was 140  obsolete PacComm Trace digis
 U   92, was 184  UIDIGI ROMS needing updating to "S"
 D   61, was  90  DIGI_NED needing updating to "S"
 R   36, was  95  obsolete RELAY. Should be WIDE1-1
 W   15, was  28  obsolete WIDE.  Should be WIDE1-1

Considering that Europe only in October adopted the New-N
paradigm, this is showing excellent progress and reduction of
obsolete digis.

For further comparison, here is l ast years January 2008 report:

> Notice the big jump in "S" digipeaters. 
> And phase out of "L"'s which do not

>  New-N-Paradigm Digis as of Jan 2008:
>  S digis 840, was 490  New-N's that support SSn-N 
>  L digis  63, was  75  New-N's (should be S's)
>  F digis  20, was  20  KPC3 old ver 8.2 FLOOD only
>  P digis  17, was  20  New-N   Paccomms 
>  1 digis  61, was  30  New-N   one-hop digis

>  Old style digis:
>  N  380, was 515  Old -N's that flood and bad timings
>  T  100, was 115  obsolete PacComm Trace digis
>  U  110, was 135  UIDIGI ROMS needing updating to "S"
>  D   46, was  75  DIGI_NED needing updating to "S"
>  R   72, was  95  obsolete RELAY. Change to WIDE1-1
>  W   12, was  12  obsolete WIDE.  Change to WIDE1-1

>  1) still show an "N" or a "T"
>  2) dont show the type of TNC in the TOCALL
>  3) dont show the "Wn,SSn-N" in the posit text
>  4) Are not using proportional-Pathing 
>  5) Are using more than 2 hops
>  6) Don't show a PHG value
>  7) ID text not condensed for best 10x10x+ display 

P.S.  Its not just simply changing the Overlay byte!  It is
adopting ALL of the New-N settings throughout the digi.  "S" is
not set until ALL of the parameters are correctly set.
