Radio should be everywhere

At the recent Radio Advertising Bureau convention, RAB CEO and President Jeff Haley outlined his vision of radio’s future, which includes audio delivery beyond the traditional transmission systems that we have used for 80+ plus years. Online streaming, podcasting, Wimax and more are part of his vision. Haley also called for broadcasters to work together to ensure that a radio receiver is in every consumer portable device within the next five years.

Read a summary of Haley’s speech at this link.

What caught my attention is that I noted a similar goal for radio more than a year ago (How to Make HD Radio Succeed: Do Nothing, Dec 2006). Haley’s challenge is a broader approach, and it has the correct goal in mind. Listeners have grown and evolved. Radio needs to grow and evolve as well.

HD Radio: More Power!

By now you have heard that there is a quiet movement to increase the power level of the digital portion of the HD Radio hybrid signal. You can read something about that in the Feb.6 Digital Radio Update newsletter.

On the surface, increasing the level of the digital carriers sounds like a good idea. More power means a better digital signal. But increasing the power raises other questions, with concerns of first-adjacent channel interference being at the top.

The results of the study have not yet been posted. I’m looking forward to reading them.

What’s your opinion of the power increase?

HD Radio Everywhere

As the digital radio rollout continues — regardless of the flavor, whether it’s HD Radio, FM Extra, Cam-D, DRM or anything else, the one obstacle continues to be the availability of receivers. There were more HD Radio receivers shown at CES2008 than ever before, but it’s still hard to find them on the shelves at the local electronics box house.

Digital Radio Express was touting its shipments of FM Extra receivers for several months, but that attention has also died down.

What’s the answer? A year ago in my Viewpoint column (Dec 2006) I noted that the real success of a digital radio format will be seen when the consumer does not have to make a conscious choice in buying a digital radio of any flavor. (Read that article:

Granted, we’re not there yet.

What’s your view? What steps should be taken to help digital radio take off?
