The message you received is incorrect, then. It isn't clear from your posts whether you are adding a conventional (non-trunked) or trunked channel to the FL, and what happens (as I've tried to describe above) differs based on that information. If a trunked channel, it also matters whether it is a single-site trunked system or a multi-site trunked system.
I suspect that you are adding a trunked channel from a multi-site trunked radio system. If that is the case, then you need to give the scanner a bit more information to work from. First is to make sure that the Favorites List has been set to pay attention to your location (so that it will automatically ignore sites that are too far away to be received). By default, location control is off. To turn on location control for the Favorites List:
MENU --> Manage Favorites --> (select the FL to modify) --> Use Location Control --> Set to On
If you are familiar enough with the system to know which site carries the traffic for the channel you are interested in monitoring, you can further (or alternatively) limit scanning to that specific site by:
MENU --> Manage Favorites --> (select the FL to modify) --> Review/Edit System --> (select System to modify) --> Edit Site --> (select a site to avoid) --> Set Avoid --> Permanent Avoid
(repeat the last portion for each site you want to avoid until you have limited the sites to just what you want the scanner to use)
