This is where you have to start eliminating possible issues.

If it's a tuner issue that is suspect, test reception with another TV. See if any of those signals lock. I notice different behaviors between my two TVs when it comes to what locks and what doesn't.

Co-channel situations can be mysterious things. Even if very weak, an off axis co-channel signal can disrupt your tuner from locking on to a stronger signal.

If that persists with another tuner revising your antenna system might be an option. Going after the UHF signals at magnetic heading 209 with no co-channel issues might yield the reception you want.

Magnetic 209 has K31MD-D (FOX), K44LE-D (NBC) and K29KH-D (CBS) in line of sight conditions.

When you say you receive Anchorage at magnetic 8, are you receiving PBS, NBC and ABC reliably? If so, you may be able to add UHF reception to your existing VHF antenna, combine antennas and get the major networks.

Cheers.
