I think it is a great market for someone to build a 223 mhz. D-STAR radio and repeaters, and the home brew crowd can get there (Yahoo! gmsk_dv_node and pcrepeatercontrolle r) but until you have an "off the shelf" manufacturer it will never grow. Things change over time and people need to be adaptable.

They are different designs for different purposes. Hams are not a managed fleet like public safety systems. That being said, creating a 12.5 kHz. band plan in the portion of the REPEATER sub-band currently used for analog simplex would accommodate more than D-STAR. P25/MotoTurbo/ NXDN/D-STAR all fit into those slots nicely. John D.
