On a Dish 625 are there modulated outputs for both tuners. It mentions an agile modulator. Does this mean that one tuner outputs on Ch 3/4 and you can pick any vhf/uhf channnel for tuner 2?
I have a 625. Go into setup and you'll find a modulator setup section. Tuner one is on channel 3 by default and Tuner 2 is on channel 60 by default. You should be able to change those settings once you go into teh modulator setup screen.
