AntennaWeb.org shows Channel 36 is on RF 25
It also shows the compass direction from my house the same as for most of the other Atlanta stations such as chanels 5, 46, 17, and 34. These stations are all SE 113 degrees from my house in zipcode 30127, and I can pick up all these with an RCA ANT1500 with no problem.
TVFool shows it at about SE 170 degrees.
and doesn't show 57 (RF 41) at all?
