Back when there was debate about the Sirius and XM satellite radio merger, various groups suggested potential conditions that might be made part of the deal. Some were discarded but others were agreed upon. For example, both companies made an open device pledge that will allow manufacturers to add features to their receivers.
One frequently suggested condition was a requirement that all new satellite radios be capable of receiving terrestrial HD Radio stations. The FCC didn’t make that part of the deal, although they are still requesting public comments on the idea. Now Rep. Edward Markey (D-MA) has introduced the “Radio All Digital Channel Receiver Act”, which would make the FCC implement that HD Radio requirement.
