"The Cambridge SoundWorks Radio 820HD, as the name implies, is a HD Radio device. HD Radio, as Cambridge describes it, "allows AM and FM stations to broadcast digital signals in tandem with their analog signals, providing broadcasters with a platform to offer multiple channels of programming on the same frequency (multicasting). " These extra channels typically come through in CD quality sound, deliver services such as real-time weather and traffic updates, and provide scrolling text and graphics content to compatible radios. There are also no monthly fees associated with this content. Besides HD Radio support, the SoundWorks Radio 820HD offers features like dual alarms, auxiliary input to connect other audio sources such as an iPod and a stereo headphone jack."This is a nice looking tabletop radio and it looks like it will play most sources of audio. An addition of an internet connection to play internet radio streams would nicely round out the package.
