1) Get on the air. Talk to your fellow APRS ops. Let APRS show
you when they are available. Keyboard. Chat... Re-discover
2) Put really good and useful LOCAL information out on the local
APRS channel for all those 2-way users and mobiles and visitors
so that the tracker owner will feel he is missing out on all
this real-time info, and will at least add ab audio receiver so
he can hear a call or APRStt announcements and messages.
3) Once we get APRStt (touchtone) going which includes Voice
Synthesis announcements about APRS key objects and messages/
bulletin/ announcements, then the 1-way trackers can get their
data by listening on the APRStt channel.
The French version of APRStt has stagnated, we still need a
dedicated programmer to consider taking on this really vital
