On the LNB setting there are three settings. One has no voltage, the second has 13 volts (Vertical Transponders) and the third has 18 volts (Horizontal Transponders). Since Dish Network/Directv uses circular polarization then you would go by the next sentence on voltages. I believe the odd transponders are 13 volts and the even transponders are 18 volts.
You are very welcome. The signal meters are really nice once you figure out the settings. A lot better to customize the meter with the frequencies you are looking for instead of trying to use the preset ones.
