Greetings, I am near the Loon Mountain ski area in Lincoln, NH and am hearing several control channels come across the scanner which sounds like Motorola. I have tried to search RadioReference but I find no such system listed. I have entered a trunk system into my Uniden SDS100 and tried Motorola and P25 Trunk to no avail. MotoTRBO wants an Input LCN which I do not know. How do you set up an unknown trunking system if you do not know what system they are on? Is there a way of mapping it out?
