[aprssig] I almost understand WIDEn-N

[Joseph M. Durnal]

Hello, I've enjoyed reading the archives from this list, I think I've
learned a lot about using APRS.

WIDEn-N, I understand what the second N is for, I think.  Basically
after each digi the value of N goes down by one.  What is the purpose
of the first n?

I'm curious what the difference would be between WIDE2-2 or WIDE3-2.

Thanks,
