Wikipedia has an article on HD Radio:
http://en.wikipedia.org/wiki/Hd_radio

It puts some remarks on the subjects you mention:

With both DVB-T and a new DAB rising as competing open standards, I don't see proprietary HD Radio being launched in Europe.

Thus, although an analog radio from one continent can be taken to another and it will work to some degree, the differences between HD Radio and DAB/DRM make listening to the other system impossible."

and

"HD Radio has been criticized for being incompatible with the standards selected by most other countries; hence overseas travel with an HD Radio, or the sale of radios to or from countries that don't use HD Radio is not possible. Manufacturers presently must design and build separate radios for the U.S. market."

Maybe Streetdeck should stop seeing the HQCT as competition and do international customers a favour by properly supporting it.
