Dish Network installer here,
I don't know how close you are to where you live compared to where the local station is broadcast from.. but connect an off air antenna to the rear of your receiver and do a local scan. If you are able to pick it up it will add the network to your channel guide..
if your close you can use bunny ears.. if you have a great distance to go.. try a larger off air antenna on your roof or something. Again, not knowing the situation your in .. dont know if this is an option for you.
