[aprssig] time for APRS second generation network?

[Robert Bruninga]

Greg and Phil

Another idea for the super-sites, is to make them a WIDE
(no relay) and make the lower LA-Basin digis be RELAY 
and no WIDE.

This makes the use of RELAY,WIDE (the universal mobile path)
a two tier system, with minimal dupes.  The mobil hits his local
digi first (usually only one) and then it relays it to the super-site
digi that covers the whole area in one packet.

Then also leave all other APRS paths out of the super-site.
It is not needed for CAn-N or any of the other generic omni
paths. (You may still need it somewher for an interstate LNKn-N
only over on the other side of the mountain, but tht wont be
used much...

Just a thought.
But it solves your concern of supporting RELAY and WIDE
and it solves the multiplle dupes that can result by doingg
it in two tiers.

Conditions have to be really good and the channel has to be relatively

clear, but here are the digipeaters I can regularly hit with my home 
station:

N6EX-4
N6EX-2
N6EX-1
ONYX (K6TVI-1)
WB6JAR-10
W6JPL-2

I can also hit these when mobile down near the Disneyland area where it

is relatively flat.  Along the 22 freeway I can generally hit most of 
these.  If not all six simultaneously, at least three or four.  The 
problem is, it is rare for the channel to be clear enough to hit them 
all or even a majority of them, but they all have the ability to hear 
everything in the basin.  I have even seen my packets digid by K7GIL-1

and W6SCE-10 when the conditions are beautiful.

I agree with your suggestion to move N6EX-2 to a lower location, as 
K7GIL-1 covers the high desert quite well and will spill enough packets

over the hill on most days I think.  ONYX is even higher than N6EX-2 -

perhaps we should look at making that a link digi instead of a WIDE.  I

haven't been able to tell how much N6EX-1 and W6JPL-2 compete, but I've

always wondered if they do compete for a lot of the same packets.  Do 
you have any data on that?
