Would it be possible for you to post a couple screen shots of what you are talking about?If you are entering it in as a conventional freq and selecting DMR then you can only enter in the color code. I have recently found that many DMR systems simplex or repeatered have a TG (talk group). to recieve these systems properly you will need to create a one freq trunked system even though the channel is not trunked. This will let you create a department and enter in both the TG and the timeslot.
The TG can be located by using the trunked discovery mode.
