I hope i have the right page. I can receive police dept signal.
OK, so the radio receives. That's a good sign.
but i can not find any one talking if i am scanning
What is it you are scanning? If you are scanning the amateur radio frequencies, it can really be hit and miss for finding active traffic. Try around rush hour (if there is such a thing in your area right now).
i do pick up the station idenifter on reapeater
OK, so you are hearing the repeaters, but no one is talking. Not surprising. In some areas of the country, there are a lot of amateur radio repeaters, but not enough users around to keep them busy. You just have to keep listening until you hear someone. Maybe check with local amateurs and see which repeaters are most active.
no one answer or i guess can not hear me. i appreciate any help
Well, that could mean that there is no one listening, or no one wants to talk to you, or you are not getting enough signal to the repeater to make it understandable. Hard for us to know. Try making sure you are outside and away from buildings. That'll give you transmitted signal the best chance of reaching the repeater. Looks like there is a 2 meter repeater in your town, do you know if it's working properly, and is there someone you can arrange to talk to on it?
Not sure what kind of radio you have, but maybe find a local amateur radio operator that can help you get started. Baofengs are not great radios, so it's possible there are some issues with it. Having a knowledgeable person assist you in testing it would help sort things out. Kind of hard for us to do over the internet.
