I wouldn't mind NASA or maybe C-Span.
~MYB~
I believe NASA is there already, and I picked up C-Span when I got the Dish tech support lady to add the PI channels. A warning there though: You will likely block a lot of those if you block the others you mentioned.
My "free" lifetime sub costs me about $20 to Dish, even though I have no Dish-specific programming beyond the PI channels.
BTW, you might find RFD-TV of interest, depending on your interests. I know my daughter is now watching some of the horse shows there.

There are no "split" locals anymore so the 148 dish really isnt needed in your case
All locals that were "split" between 110/119 & 148 or 61.5 are all now on 110/119
