Yes, I'd be happy with an ATSC modulator, if I can't get ATSC directly
out of the Dish/DirectTV satellite box. Steve's suggestion appears to
be NTSC output, not ATSC SD or HD. But thanks for the suggestions.
Roger's suggestion of the Sencor board
(http://www.sencore.com/products/modulators/125) appears to be the
ticket, if price were not a consideration. I filled out their price
quote request, just for fun. I'm expecting $500 per unit.
And Brian (BEWW) leave it to a Electronics Engineer to warn (even in
jest) about impedance mismatches! I'll have to see if I can find my
circular smith chart calculator.
