Hi Alan;

A mixed mode FM / D-STAR repeater is quite feasible! - if you connect to 
Allstar node 2200 you will be cross-connected to D-STAR reflector XRF005A.

The FREE STAR* team offers a solution, where you can leverage an 
existing app_rpt installation and add an open source D-STAR (FREE STAR*) 
solution on top.

You can use a separate sound fob or GMSK modem board, etc., then with an 
external multiplexer switch between DV and FM mode into a common (true 
FM) repeater.

Please contact me off-list for further info.

Thanks to Jim, Steve and others for providing a superb FM platform!
