Well I don't think I can enter a space using touchtone so it must need to be fixed in the app_rpt software.I am running the latest software as of May 9 2012.  I'm not sure where in the C code to fix this but I think maybe it would be in gps.c

                 sprintf(buf,"%s>APSTAR:;%s-12*%02d%02d%02dz%s%c%sA%s\n",                call,theircall,tm->tm_hour,tm->tm_min,tm->tm_sec,lat,overlay,lon,comment);

if theircall is less than 6 char then theircall-12 needs to be padded on the right with spaces to make it a total of 9 char in length.  
Yes, that's precisely where the fix needs to happen.

APRSTT on my systems works for some call signs but not for some others.  

Here is an example from the aprs.fi raw log.

Can anyone shed some light on why N9DOA shows up as "[Invalid object]"?  

Is it a problem with aprs.fi or with the code in app_rpt, or with the way I setup rpt.conf?

The reason is that APRS object names must be padded on the right to be exactly 9 characters.  WB9UUS-12 is 9 characters, but N9DOA-12 is only 8 --- you need to pad it out with spaces so the payload is:

;N9DOA-12 *151333z4030.28N708859.28WAAsterisk app_rpt user

(note the extra space before the "*")
