The value is to about 40,000 existing owners of APRS radios.  The ASTAR REPEATER gives them a gateway into the local and global VOICE connectivity of the DSTAR system.   The APRS radio is necessary on the analog repeater side to ID and DISPLAY all connection and link maintenance data.

Bingo  You just made the point perfectly.  Thanks
