     Your preaching to the choir. (warning: soapbox comments to follow)

I have tried unsuccesfully to get the digi owners/operators in upper
East TN/Southwest VA to follow the new N paradigm, and have tried to
understand the way they have it set up now. To my knowledge, we only
have 1 fully N compliant digi here (I can't speak for Knoxville, they
do seem to be more compliant then we are here however based on my
observations). I'm not sure what the problem is with getting them
changed, could be lack of manpower, equipment limitations, time, or
resistance to change.

Before I go off on too much of a tirade, there are a couple of
assumptions I have that I believe add to part of the problem here:

1. High level digipeaters (mountaintop) should not respond to Wide1-1,
that is what fill ins are for? We have several that respond to it....
2. Repeater objects. I plan on implementing this myself on a fill-in
digi, not the standard I know, but better than nothing. I am
considering a 2 hop path to blanket the area. I will be setting up a
simplex IRLP/Echolink node soon on 440 that I will be beaconing as
well. Ideally I think just one high level digi should implement this
for the repeater that is used most often in this area.

I've been using APRS for two years now and I still can not understand
my local network. My gripe is that their have been standards put into
place that have been suggested for use and they aren't. It makes it
difficult for end users such as myself to figure out the "best path"
to get a packet out.

</soapbox off>

How can I as a user make APRS better in my area? I encourage everyone
I know that uses APRS to run the suggested settings, but I still feel
like it's a constant uphill battle.....
