I've got the BC796D down to a science pretty much. I've gotten them to scan, trunk, and decode P25 system with no issues. I cannot get the 785 to trunk though. It will decode the system when I manually tune to a frequency but it will not trunk or scan the talkgroup on the frequency. It is almost acting like an analog system just working on manually tuning the frequency. Any idea's? The step inside the 785 is limited to 5,7.25,10,12.5, more and auto. There is no 6.25 like their is with the 796 when you do the firmware update.
