Around here (greater metro Los Angeles area) the overwhelming amount of 
APRS operation is mobile.  They are simply not going to be exchanging 
text messages, even if they DO have a two-way station.   

[Indeed mobile text messaging in CA is now explicitly illegal as of Jan  
2009, after the hand-held  voice cellphone ban  of a year or two ago 
resulted in an upsurge of text messaging as an alternative.]

Since he can't receive, how is the tracker owner supposed to know what 
he is missing?

Once again, let me point out that I have been beaconing my Echolink node 
in Pasadena as an APRS object in one of the busiest  APRS "markets" in 
the country (greater Los Angeles, CA area).  I have had exactly ONE user 
access it as a result of APRS  announcements.    

(The others found it through the Echolink website "currrently active" 
listings, or from my talking  it up at  local ham club meetings.)

Further, I have been using UI-Events to announce the monthly meetings of 
four different local ham club meetings in the San Gabriel Valley  (the 
20 miles or so east of downtown Los Angeles)  for about 8 months now.  
(I beacon each bulletin once every 29 minutes, starting at 3:00 PM the 
day before the meeting until about half-way through the meeting the next 
evening  . The idea is to get two shots at the afternoon "drive time" 
rush hour "audience" before a given meeting.)

So far, not one person has appeared at any of these meetings as a result.  

Note that this is in an area where a population of at least *4 million* 
is within the footprint of the N6EX-3 digipeater I use to send these 


I think one has to face the fact that, like it or not,  everyday APRS 
operation *HAS*  been "hijacked" into  primarily an AVL (Automatic 
Vehicle Location) system........
