Radio shack people are not trained to help you. They exist solely to sell you cell phones and extended warranties. Most have no clue as to the electronics they display - let alone help you understand your new purchase. Talk groups are not limited to a single frequency. Select the site that is closest to you, define the bank as MOT, enter each of the control channels, and then hit trunk and enter the talk groups desired. Communications are shared among the frequencies listed, permitting greater flexibility for multiple users and simultaneous transmissions. PS You won't hear a whole lot on that TG. If you live in Morris County, you may wish to monitor some of the municipal action that is analog in nature. Check out the Morris County Database here.
