If you are in the flat mid west area of the U.S. any ATSC receiver should work for ATSC DXing. The newer A/74 compliant ATSC receivers are what I use now. These tuners have multi signal processing that handle signal delay kind of mimics OFDM type modulation. Unfortunately the ATSC receiver manufacturers dont list if they are A/74 compliant in the the manual. For HDTV DXing I know the Samsung DTB-H260F and the ePVision PHD-205 use A/74 compliant chips all of the coupon approved converter boxes have to be A/74 compliant all dont seem to be equal. I recently purchased an Apex DT250 converter box first day testing the DXing capabilities did 110 miles in Florida. The Samsung DTB-H260F, ePVision PHD-205, and Apex DT250 do have manual channel input.
