Quick update... Finally got WSB-DT. Funniest thing how I got it.
I had about 10 extra feet of RG6 in the attic so I cut it out, rebooted the RCA receiver, did a channel scan and there to my surpise was WSB-DT!!
I am now getting all the major networks out of Atlanta in HD. ABC, FOX, NBC, CBS, WTBS, WB, UPN, and PBS. All have a signal level of 80% or better.
Not bad considering I am about 30 miles from the towers, have 100 foot tall hardwoods about 50 feet from the Winegard non-amplified "Bat Wing" antenna which is mounted on my roof right next to the DirecTV dish.
Next purchase... HD Tivo. I almost have the green light from the wife too. The more and more she watches HD the more and more I hear "I wish I could record in HD!" I imagine we'll have one ordered within a couple weeks.
