I purchased the Whistler ws1040 and I have been pulling my hair out for 2 days now. I finally figured out how to program channels. However, I would love to listen to Central Falls police and Providence police. I programmed in the frequencies I found but nothing ever comes on those frequencies. After several hours of Google searches I found that they fall under something called riscon and trunking. I watched a YouTube video but didn't seem to work. Can someone please tell me if and how I can hear these channels. I truly appreciate any help as I have been losing my mind trying to figure this out.
