EDACS - Unitrunking unkeyed mic end beep

[Bear15]

I was using a BCT15 to monitor my local FD on EDACS96 and never really notice the end four beep (unkeyed mic) until I have setup two SDR dongle with unitrunker, is there a way to silence these four end beeps and still able to follow a conversation? all LCN numbers and frequencies are right.

Thanks!
