> APRS Message contents are limited to 67; add in the addressing and you get
> up to 84.
> :[DESTCALL+PADDING]:[MESSAGE]{[MESSAGEID]
> 1+9+1+67+1+5 = 84
>
> 84 is way less than 214... Where in the world did this 67 come from? Even
> including 8 digipeater hops in the third party header, I still haven't been
> able to justify why we constrain the APRS messages so badly.
>
> 7. Where did this 67 character limit on messages come from?! This really
> bothers me now.
