[aprssig] EchoLink APRS-IS Ojbects Mothballed re re

[rhonda & randy]

Hi Keith, but isn't Xastir a Linix based program? I am almost sure that
these two hams in Vancouver run Xastir, Dave can't remember his 2 letter
call but lives in Kerisdale west side, and his buddy with palm tree in the
downtown east side.
So what's the deal with the mothballing of objects?

Got to run...

I tried entering some stupid settings... you can only enter two digits 
for the the maximum number of tries, so that is limited to 99. With that 
setting, the shortest retry interval it will allow you to enter is 198 
seconds. If you go to the other end of the spectrum, the shortest retry 
interval you can enter is 7 seconds, and with that setting, you can only 
enter a maximum of 3 tries. Neither setting would really clutter the 
network. The help clearly explains the settings and the relationship 
between them, and it won't let you enter settiings outside those 
parameters. My settings of 5 retries with an interval of 10 seems "OK" 
to me.

As mentioned above, you can't really abuse the network with improper 
settings. Improper settings could lead to retries beinig spaced out by a 
ridiculous amount of time.

No problem! When you say "popular clients" or "simplistic clients" or 
"many clients" or "most follow-on APRS" I usually assume that you are 
referring to UI-View - hi! UI-View still works as well as it ever did, 
but I know that eventually someone will write a "replacement" that does 
everything and without needing add-ons, does it better, removes 
limitations in displaying new symbols, doesn't allow you to enter 
abusive settings, has excellent mapping options, and so on. I may not be 
the first to try it, but I would be among the first to urge adoption if 
it worked well. With that said, I've never even used Xastir, but with 
all the good things I hear about it, I'm surprised more people aren't 
recommending it. Maybe the replacement is here and we just don't know it 
yet.
