Dear Bob:

First, let me say I am grateful and appreciative of the work you have 
done developing APRS over the years. That being said...

I know that you are a big proponent of APRS 'doing more' than just 
tracking. I sometimes though get the feeling that you'd like to see all 
trackers just 'go away' and APRS to be used for other things. This part 
of APRS is what I can do right now. I do not have a $300-400 Kenwood 
radio with all the bells and whistles to do messaging and 
auto-switch-freq when a close by signal is detected for voice QSO and 
all that. It is neat, but it costs money, which I need to use for other 
things right now.

I am starting to get a sense here by some that there is an agenda for 
APRS...that unless you can pony up the $, and do it the way some think 
it should be done, that you should not play the game. I didn't think 
that's what ham radio was about.

It appears there is no point in running APRSDroid if the only ones that 
can 'see' me are on -IS, and gosh forbid I should be wasting bandwidth 
with my radio setup spewing full NEMA sentences, especially since all I 
can do right now is run tracking only.

Perhaps I will just put my inefficient, bandwidth wasting APRS gear away 
for now and find something else to do.

Sorry if this seems a bit sour, but it is just the feeling get from some 
of the replies I have gotten here.
