Welcome to the world of HD broadcasting or rather reception. It would be helpful if you could offer up some information on your antenna (type, height, obstructions...).
I personally live on the westside of Kokomo and have no trouble receiving Indianapolis HD. I didn't even realize WXIN had a blip until I read this thread.
You can read my antenna configuration in my signature. It is up about 12 feet above a 1 story home with a walk-out basement. I can pick up stations from South Bend/Elkhart and am looking forward to Ft. Wayne being on air soon.
Naturally, I had no problems receiving channel 18 out of Lafayette when they were doing digital braodcasting. (I think they are still off the air.) I have read in these forums that they will be doing HD by Jan 1.
Don't forget to fill us in on your Antenna. Here is an old thread I started asking about antenna suggestions. It might give you some help...http://www.avsforum.com/avs-vb/showt...hreadid=156104
