I did step by step you instructions .The system have 15 Frequencies but no hearing no one of them , i programmed it as trunked dmr . thanks for the help!
OK, my appologies, I though you did something else.
So you are monitoring in analog mode and you don't hear a thing on any of those channels, no reception at all, but other systems are working.
One thing possible are attenuation set on the system than you cannot receive, or your location are pretty much dead RF wise from that particular system. That can happen. I have one watertower in metal in the direct line to big site across town and I'm lucky if I can monitor anything from there by receiving reflections from objects behind me and at the sides. If I go out and move just some 100 meters at the side I get almost full signal strenght.
Try open squelch, set it to 0 so you'll hear the noise and move around and see if you can get any kind of data signal in analog mode from the control channel frequency.
Is it a huge TierIII DMR system with 15 frequencies or is it different sites? Do you know where the nearest site are located? Use the map that tells you if you have some obstruction in the way to the site. Remember to set the antenna hights. A radio site probably has a 20-50 meters height.
RF Line-of-Sight provides radio path information for mapping long distance SCADA radio communications by using antenna height and topography.
