I don't think Dish provisions sats; they just provision (authorize) channels, regardless of the sat it's on.
It's a "modified" Turbo HD dish with the EA LNBF for 61.5/72/77.
I've never been able to find 77, but there's only a bunch of locals on it.
Do you get good readings on all transponders on 61.5? How about TP13? I am about as far north as you are but farther west.Unless things have changed sat 77 could not be used for Maine so I don't think it will reach N.S. I have 2 Dish 500's in Rangeley Maine with single lnb's for 62.5 and 72.
