Now that is a great story for the use of APRS, and the use of
messaging on top of the presence data is a great idea, well it is
all AX25 in the end, great story and keep up the great work.<br>

have... just on principal....<br>

love to take ACARS and AIS and have the option of
converting to same format.. .interleave them into the
serial stream and have that too.... we had one of the

might be a lake or harbor so tracking those with existing

thoughts).... I worked on an system 18 years ago that had
two speed (1200 and 9600) digis to accommodate trackers
and digi relay on one freq... when you go back, I believe
this was the first time - time slot APRS happened... using
PACCOMM TNCs... those of you who've been around for 18
plus years on APRS (like me) possibly recall the effort
I'm talking about...you can have the pain of two speeds on
same freq.... same system tried to do ROSE network to
control movement of data back to command center... no way
I'll go that route any time soon.... the world has changed
in 18 years. But we continue to saddle APRS with backwards
compatibility... I don't need the baggage.... messaging...
don't need it.... auto QSY... don't need it...
bulletins... don't need.... this is about TRACKERS.... for
tracking acute care patient transport and maybe other
critical asset tracking... where no cellular exists.... or
where crowd density precludes cellular being reliab</span></font></blockquote>

Ambulance drivers don't need to message some of the odd
vanity ego stuff that I see with some APRS users.... I did
AVL that predates APRS - APRS wasn't the first GPS tracking
approach over RF by a long shot....but I give Bob credit...his
baby has moved some of the common use forward at a low
cost.... I just don't need everything and the kitchen
