I have nothing invested in D-Star but about 500 dollars.  My emotion is 
based on my investment in APRS.   People say that D-Star "violates" the 
spirit of ham radio.  Doesn't rooting for the demise of D-Star violate the 
spirit of Ham Radio?   Think of the time, effort, physical labor, and cash, 
put into the already incredible growth of D-Star by other ham radio 
operators.  My point is and was that people here get very upset by APRS 
detractors in the Ham Radio community.   Can't we here on this SIG, be 
better than that?  Apparently not.

You seem to be totally unaware of the incredible growth D-Star has seen in 
the last year.  I spent 3 years in the 1990's to get a dozen people using 
APRS in Phoenix.

You've been the victim of D-Star FUD.

D-Star radios can transmit on standard FM, just like any radio.

Standard repeaters will not work with D-Star mode.  But since we've seen 
that D-Star works very well on AO-27, standard repeaters can be modified to 
deal with D-Star.

The San Diego D-Star repeater on Mt. Woodson which was KE6KRU until last 
Saturday and now KI6KQU under the auspices of PAPA, is a voice repeater 
modified to pass D-Star traffic.  It is by far my favorite D-Star repeater 
as regular users go.

D-Star takes less bandwidth than analog FM.   In marginal conditions D-Star 
works better than FM in many cases.

And if you think Ham Radio will live on - I think you need to look at the 
numbers of people coming into ham radio again and their 
demographics.    People who want to stay the course and stick to a 1998 
model of ham radio are dooming us.
