That should work fine.

No, that is the jeep symbol and CSE/SPD so they should be just fine.  I would think that that should work.  And if that is being generated by DPRS, then I guess the issue is resolved and things are just peachy in APRSville...

Great!

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.

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.
