I. I notice if i enter the control channel of a trunking system into direct entry I dont hear anything except the DAT appears in the bottom right of screen. what do I turn on, or off, so that I can actually hear the data sound of the trunked system on the control channel? I like to hear the noise so i can gauge by ear the strength and hearing the sound also helps me recognize the type of system



II. in a favorites list how i browse just the groups i have avoided? when I go to my avoids to unlock something i have to scroll thru all of the conventional channels that i have avoided just to get to what i want to unlock.
