[aprssig] What settings for igate?

Hi folks,

Getting back to this project after being distracted...  It's still not quite 

I found a web page which lists internet servers, and configured a new 
interface on XASTIR for socal.aprs2.net, port 14580.  Checked "activate on 
startup" and "reconnect on net failure".  The three fields "pass-code", 
"filter", and "comments" are blank.

The interface is shown as "UP", and I can see that I'm listed on the server 
as connected, and the statistics are are incrementing.  But I'm not seeing 
anything local show up on Findu.  (I tried sending a packet from my D7 on 
low power - it shows up on my XASTIR map, but not on Findu.)

I note that the server lists me (and some other stations) as "No" under 
"Verified".  Is that the problem - is there another step that I need to take 
in order to have traffic show up?  What is the procedure?

The first option will change your _own_ transmitted objects to
Base-91 Compressed format, instead of Standard APRS non-compressed
format.  Your choice on that one.

Don't activate "Alternate Net" unless you want to only see people
that are also using that same Net.  This is mostly for events or
other instances where a group of people want to interoperate yet get
rid of other stations/objects off their map.

The third will drop any duplicate packets received so that
tracklines don't do weird reversals on you.  This is mostly for when
you have an digi in your area that is holding packets for a while so
that tracklines start doing weird things on your maps.

That's for the ALTNET setting.  If you change it to "APX"
temporarily and then turn on ALTNET, you'll see how many Xastir
stations are in your area.  Remember to turn off ALTNET when done

Probably more QRM.  I'd just gate to the internet then in that case.

You have to create an internet server interface and connect up

Doesn't matter in your case.  If you're running APRS software and/or
not running as a digi, you can use old hardware just fine.

You do want to use the new paradism paths though.  WIDE2-2 or
WIDE1-1,WIDE2-1 are the usual recommendations.  You can also put in
specific digipeaters if you have one best path away from your house.
