So I’m trying to program Lebanon NH Fire Dept into my icom portable radio. I’m a little new to this, so please be easy! I know their frequency is 151.235 with an NAC of 800. So my question is, do I need the unit ID(hex & dec) and the talk group ID? And if I do need these as well, does anyone here have that Information available?
thanks for your help!
