[aprssig] DSTAR Freq in Status text?

[Michael J. Wolthuis]

What about using the Tone spaces to put DST for D-Star maybe?

ie. FFF.FFFMHz TDST or FFF.FFFMHz T d*

Note, I am not trying to send this from a D-Star radio (well that too), 
but for this status text it is from RC-710 connected to a D-Star 2820.

>>> 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.

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.
