Dish network receivers arent meant for tuning there meant for checking signal. Alot of the time you will pass a good signal before it will even show up on screen. Now before some one gets a big stick and tries to hit me i will say it can still be done but you have to be very very slow, just remember your aming 2ft of metal thats 23000 miles away from something thats the size of a dinner plate. So stop being cheap and buy a cheap meter.
