If you are asking about the DV3000 or the ThumbDV, then yes I have done this. I am in the middle of working on an application that allows one to use the DV3000/ThumbDV just like the DummyRepeater mode works for DStar. I have been using it for a while and it works very well on both TX and RX. This is part code is an outgrowth of a project to create a gateway between DMR and ALLStar/Asterisk and that project is nearing its completion. Once I get a chance, I will open source the code and others can build on my efforts.
A bad youtube video:
The quality was not up to what I wanted so I never released it, but I am tied up with some family things at the moment and this will have to do. I will do a better one at some point.
