[aprssig] WIDE settings

Thank you Gary for such a good explanation of the settings.  Mobile
stations should use both "WIDE" statement, and base stations should
only use the single "WIDE" statement.

The first "WIDE1-1" will allow 1 hop from "any digi". If this first
digi does not get the packet to an Igate, then the second "WIDE2-1"
will allow a second hop only if needed to find an Igate, but the max
is 2 hops with this setting - s this correct?

IF a mobile station with the "WIDE1-1,WIDE2-1" setting is heard by a
"high digi" first, then there would only be a single hop because the
"high digi" will ignore the first "WIDE1-1" and only act on the second
"WIDE2-1" statement and allow only a single hop - is my understanding
correct??

Then a mobile running WIDE1-1, WIDE2-2 could have a possible 3 hops,
the first from any local "fill in digi".  The second WIDE2-2 will
allow a "high digi"up to 2 hops (if needed) to reach an Igate.  Once
the packet reaches an Igate, there are no further repeats of the
packet.

I think I understand the meaning of your term "high digi" (major
digi?) vs "fill in digi" - In as I said, I'm just learning this stuff
so I am not familiar with the old RELAY setting).  A "high digi" is a
digi that has a large coverage area, while a "fill in digi" is more
like a home station setup to digi, and would have a much smaller
coverage area.  The settings for these digi's depend on the station
owner to correctly set the parameters of his station depending on the
coverage area each digi is expected to have. (am I correct here?)

When looking at an APRS map, sometimes I see a solid green star - that
is a "fill in digi" and the green star with the yellow "D" is
considered a "high digi"???

Thanks to all for any and all help with my quest for greater
understanding of this very interesting aspect of ham radio called
APRS.
