I have just installed a Winegard HD8200P antenna. On my HDTV I can pick up all the analog/digital signals fine, however, on the 622, (digital only), one of the stations only shows up at 66 signal strength and is basically unusable. Are there any issues with the 622's tuner? Or should I just delete that channel and rescan to see if it would pick up OK? Again, this channel WTHR 13 out of Indianapolis, IN comes in perfectly fine if I connect directly to the HDTV. Thanks for any insight or advice on this problem.
