This has been my experience many times:
Pull into campground, run a scan, select channel X with the remote.
Go to another campground that is out of the service area of channel X.
Do not run a scan.
Turn TV on and select channel X. A program with good quality video and audio is displayed. It is not the same channel as it was at my previous location, but I did get a channel without doing a scan.
Also, I can arrive at a new rv park and without doing a scan, pull up every channel on the park's cable guide by just selecting the channel on the remote.
Do you still think this is not possible?
