That may help. I live about 75 miles from the PBS station transmitter I would like to watch after 17 Feb. I do have an external antenna pointed in the direction of the transmitter. As a former broadcast engineer, I am familiar with coverage contours, and I know I am currently outside of the PBS station's. Of course, that doesn't mean I don't want to watch it. I can receive closer DTV transmissions, and I have to agree with others, the picture looks fantastic! Craig...
