Bad news....he DOES want low def radio....
"Adelstein is proposing that the companies be required to include a digital radio tuner in any radios they subsidize that also include regular, non-digital AM-FM service."

This 
could be construed to mean that 
only the radios SIRI/XM subsidizes which 
already contain a standard AM/FM band would be required to
 also contain (the failing) HD radio as well. 
 
We are accustomed to these kinds of odd phrases, they seem to abound in all sirius matters. 
Also, I do not quite understand what Adelstein means by the word 
subsidize  in the context he is using.
