For grins, I took that chart and added the USA and APRS GLOBAL
statistics on it.  And you can see why APRS is still such a tiny
niche, that unless we start getting others involved, we still
are only a side show..

Besides getting more radios and devices and more INFORMATION of
value to the local mobile on the air, getting APRS used at all
local events even by Touchtone users is a step in the right
direction.  Please see the APRS Touch-Tone spec:
