Keep in mind this only true for the NJ State 800 system. The NJICS system does not simulcast across all sites/frequencies. At least not yet.
Program the Site frequencies in for the area you live closest to. For example, if you live in North Jersey, program the Site frequencies for North Jersey. However, you can program and hear ALL tallkgroups in the entire system. The TGs simulcast over all sites.

OFF-Topic question for you, do we know yet if the NJICS has plans for a statewide simulcast like NJSP has now?
