I just signed up for local channels today, but I seem to not receive them. The Dish people are sending techs out again to check why Satellite 110 did not come up when I diid Check Switch. I have a Dish 500 and I think a Dish 300. I believe the 500 is setup for use with the International Channels, and I do not get Channel 100 only 101, I have never gotten 100. Should I be able to recieve locals without an upgraded dish? The rep said the one 500 should be enough.
