[aprssig] IGate wildcards/Telpac data

I don't think we should stray from the AX.25 specs for convenience or
filtering purposes.

Should we start prefixing weather stations with WX- , balloons with BA- ,
Digi's with DI- , etc. ?  Of course not.  So why do it with Winlink Telpac

As far as IGate wildcards, I also agree that it should be discouraged.  By
restricting the use of wildcards, it encourages IGate operators to monitor
and attend to their stations which is part of network stewardship.  To many
"set it and forget it" abilities when dealing with the tremendous amount of
data on the APRS-IS combined with an unattended IGate just opens up the
network to potential problems.

The discussion is just starting, hopefully more people will chime in. Most
the people that are knowledgeable about APRS are here on this list, and I
this is an issue of considerable import. If in the end only two people care,
then fine, I'll make the change and end my objection...

Again, who is transmitting such callsigns? When someone sends something on
APRS IS and it doesn't appear on findU I have always heard about it pretty
quickly. AFAIK, this proposal to use WL- is the first use of non-AX25
in quite a while. 

Still, I'm really not fighting the 9 character issue, that isn't the opinion
seeking from people. The issue I'm taking up here is using wildcards in
and relying on filtering to reduce the load to the RF network to reasonable

Even if I were to agree that any 9 character callsign is acceptable, that
is quite separate from the issue of usign a wildcard gateable callsign for
Telpac nodes. Do not focus on the 9 character issue, even if findU had
supported any 9 chars as callsigns, I'd be arguing strongly against the
to IGate Telpac nodes based on wildcards. This WILL occasionally result in
to RF networks, and WILL erode the sentiment of APRS users towards internet
originated data.
