There is a new standard of radio broadcasting.  Like HD-TV, HD-Radio
allows current stations to both broadcast new signals with higher
quality and have sub-stations within the carrier.  One of my local
stations in Boston (WROR) is now identifying themselves as WROR-HD-1.
The programming they broadcast on their old FM station is the same as
their primary HD-Radio broadcast.  The only difference is that the HD
broadcast is supposed to be CD quality and digital.  In addition, they
also have new special interest channels.  Since WROR is a Classic Rock
(60s, 70s, &80s), some of their sub-channels is "Nothing but the 70s"
radio.  If you are interested in learning more, you might start by
visiting:  http://hdradioboston.com

Now you know as much as I do.

(Warning, I don't yet own a new HD-radio receiver, heck, I don't even
own a radio that has a text display which can print out broadcasted text
concerning the song currently being played.)

They've been hyping HD-Radio quite heavily in the Boston area.

This is now quite OT from MythTV....
