Hi Oilmillcharlie....I live in Westerly and most of the frequencies on my scanner in the area have been found just by searching. I listen mostly to the fire/rescue. Plus just the local police in Westerly and Pawcatuck. I dont hear much rail activity. I live right outside of downtown Westerly at a good elevation. I am a ham radio operator, but active only mobile. I am still looking for interesting frequencies in the area. I have heard on 155.415 an agency, probably police from out of Long Island. With just an indoor whip too. I am 100' above sea level with a clear shot to the south. I do have 154.160 in all my radios but dont bother too much with the tone squelch unless its a frequency that has other stuff coming in from a distance that I dont want to hear. I am not familiar with DCS. Do you need a digital capable scanner to use it? bob
