I am familiar with GRE's repeater-finder feature where you can park on an LTR channel in Manual mode and it will tell you the repeater number. Does the BCD396XT do anything like this? Do you even have to program in the LCN when you are programming an LTR system? I am just curious as to what I may run into if I get a BCD396XT and find a new LTR system... Thanks!
