It appears all the stations you listed are analog, won't do you any good to tune any of them in if you are looking for digital/HD.
I did a lookup at tvfool using 16662 and the nearest digital fox station is WWCP approximately 44 miles away. I suggest you use tvfool.com and enter your address then select Digital Only results.
You may want to check the HDTV Local Reception Info section here to see if there is a thread for your viewing area also, would put you in touch with people local to you to see what they are using for reception.
