Fred - Does your heater stop the dew on the corrector plate of the SCT? I think my problem is that I turn mine on too late... and it takes a while to warm the corrector... mine will fog up, and once it fogs, its pretty much all over, I cant get the corrector to clear up just using the heater.. a hair drier helps, but it generally only buys me some time..
