Thank you 3 for replying.

The Polaroid TV was bought in February, 2009. The Tivax tuner (used on the RCA ColorTrak) was bought fall of 2008.. The Sony (the largest TV we have - the "main" unit if you will) is a KD-34XBR970 that was bought March, 2007. It's a CRT-based 250lb monster.

I will certainly try to rescan, but I think y'all are answering my question in that not all digital tuners are created equal. I think I might try the Tivax on the big Sony TV and see what that yields. My biggest peave is the Ion channels on the Sony (including Qubo which my kids love) - some days they are great, other days horrible. I assume that digital TV is affected by weather much like dish-based digital TV can get "rain fade". The other nuisance is the inability to tune anything on PBS with the Sony. Again, I will calibrate my antenna to true North in relation to my antenna rotor's true North.

I apologize - I forgot to mention that I have an antenna rotor (old Permacolor unit). Works good. Even turning the antenna, however, has not fixed these problems with some channels. I will get up there to the antenna, double-check that the unit is tight (wind cannot turn it), and then calibrate to true North. Then I will use tvfool.com data to work my directions. My family is used to the idea of turning the rotor to the correct degrees for the station they want, so that's no big deal.

Thanks again everyone. I will keep you posted as I work my problem. Any other ideas are welcome and appreciated!
