You can easily do that in the Profile editor.Look in Sentinel or the RR database at the VIPER system in North Carolina, Guilford, Statewide Systems. There are hundreds of system talk groups and hundreds of matching (and some not so obvious) sites. I want to narrow it down to a few of the local systems in my area and the affiliated sites. I deleted the unwanted talk groups and left the sites because I don't know which sites to delete. It still scans all of the sites even though I deleted the system talk groups. How can I clean out the unnecessary sites?
