Dish 1000 will not pick up 61.5. I used to live in Baltimore and had a SuperDish to get 110, 119, & 105 for locals. I had some neighbors that had a SuperDish and a 61.5 for foreign language programming. If you look at Dish's site, each channel will tell you which sat it's on, so you can tell which sats you'll need to "see".
Since Baltimore locals are now on 110, I believe the only dish you'd need for basic would be a Dish 500. Currently, HD channels are not available from Dish in Baltimore. The CSR might know where they'll be at such time they become available. I would think a Dish 1000 wouldn't hurt, just so you're ready, but you probably don't need it for your standard package.
