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.
