    Re: HD Radio

    From Wikipedia:

    HD Radio is the trademark for iBiquity's in-band on-channel (IBOC) digital radio technology used by AM and FM radio stations to transmit audio and data via a digital signal in conjunction with their analog signals. It was selected by the United States Federal Communications Commission (FCC) in 2002 as a digital audio broadcasting method for the United States,[1][2] and is the only digital system approved by the FCC for digital AM/FM broadcasts in the United States.

    I was also interested in the details of this feature and went searching. Here's what I found:


    HD Radio explained:

    HD Radio in vehicles explained:

    From the XTS owner's manual:

    HD Radio Technology

    HD Radio™ Technology is a free service with features such as static-free sound, more programming choices on local FM HD2, HD3, and higher, and on-screen information such as artist and song title.

    HD Radio Technology Channel Access

    To access HD Radio channels:
    1. Tune the radio to the channel.
    If the channel is broadcasting
    HD Radio Technology, the radio
    will automatically switch to digital
    audio, indicated with an HD logo.

    HD Radio channels can be saved
    as favorites. Songs can be tagged
    for download to a connected
    iPhone® or iPod touch.

    If the HD Radio signal loses
    reception while listening to channel
    HD1, the radio will go back to the
    main non-HD Radio channel.
