DMR to Analog Bridge PTT assert quirk


David Ranch
 

Hello Everyone,

I have a working Brandmeister talk group to Analog Bridge setup working here but I see a PTT quirk that I'm curious if someone can comment on. 


If I key up the local DMR repeater that's in the Brandmeister talk group, this Raspberry Pi 3B+ setup using a URI-X sound card will light up the PTT LED on the URIX but then go off, then light back up and stay lit.  Beyond that, everything works as it should.  I see this behavior regardless if I use the SW IMBE vocoder or if I use a NW Digital THumbDV.  

Any thoughts on how to fix this "ACTIVE_FLAP" issue?

I've also attached a 7.7MB video of this behavior though I don't know if the Groups.IO system will accept it.  Let's see.
