Unfortunately I have been unsuccessful in encouraging the DPRS conversion to implement the FFF.FFFMHz part of the APRS format.  I do understand that D* and APRS are apples and oranges, but since the fact that the packet was originated on DSTAR is coded elsewhere in the packet, it could be easy to distinguish.

Yes, that is the "spec" it must be FFF.FF?MHz with the ? being a digit or a space...

My hope is that we have the best integration of D* and APRS as possible.  I do not have any DSTAR equipment, so if you have any ideas how we can better cross communicate these systems, I am all ears.  Especially in light of the Universal HAM Messaging Initiative: www.aprs.org/aprs-messaging.html that is attempting to make sure any ham system can text message any ham on any system from any system.
