A favorites list is composed of one or more systems. If you download from the database, you will get only the service types you have enabled. If those services types are not enabled in the scanner, they will not scan. If you create your own favorites lists from scratch and don't enter service types on conventional frequencies and trunked system talkgroups, the service type of frequencies and talkgroups defaults to Custom 1. In this case, turning off Custom 1 in the Sentinel profile or in the scanner will disable all systems where the frequencies and talkgroups have a service type of Custom 1. How many favorites lists do you have? If you are having problems with one favorites list, highlight the list and go to the File tab in Sentinel and Export to hpe file. You will have to right click on the exported hpe file and send it to a compressed (zipped) folder to be able to attach it. In your post, click on Attach files and Open the zipped file. I will check the favorites list for problems.
