Help File: Last-Minute Digital-TV Tuning Tips
Q My digital-television reception has gotten iffy. What should I do to fine-tune it before analog TV goes off the air on Friday?
ANothing. At this point, you might as well give it a rest until after June 12. When analog TV signals go off the air at the end of that day, many broadcasters will make upgrades to their digital signals -- and then you'd have to redo any antenna adjustments.
The biggest changes will come as a minority of stations move their digital signals to airwaves now occupied by their analog broadcasts. In the Washington area, for example, WJLA and WUSA will relocate digital transmissions to their old VHF slots.
You won't have to learn new channel numbers, but you will need to have your TV, converter box or video recorder rescan the airwaves to pick up these and other signal shifts. Usually, you'd do that by pressing the remote control's "menu" button and then navigating to its channel-setup screen.

If you still have reception issues after a week, then consider upgrading antennas. (See http:/
