Yes, that seems to be the answer. The packets in question all have 
trailing spaces until they pass through one igate where the spaces 
disappear. I believe the spaces are part of the OT reporting temp and 
voltage in the comment so removing it would require turning off the 
reporting or adding something extra to the comment. As far as I can 
tell, the igate in question is using APRSISCE win32 (APWW08)
