Hello SkySurfer80. While I don't live in the Crossville/Cookeville area or even in Tennessee I do know of your location for another reason. Back in the 70s/80s my Dad worked as a security guard for the Roselon Yarns (Roselon Industries, Inc) plant up here Pennsylvania.
When they stopped...
I've never used that receiver but would think the simplest way to update a channel that has changed frequencies is to just do a manual scan for the channel on the new frequency it is on. If there are no channels left on it's old frequency just delete that transponder or keep it if there are. :)
OK, just tried that and I'm seeing it too. Like, waylew, the information is incorrect. It puts me in Jamison City, PA. Heck, I had to look that up as I had never heard of it but at least it did put me in Pennsylvania! :D
