For WAMU and its listeners, HD Radio means more slices of pie to go around

As a self-proclaimed evangelist for HD Radio, I am often asked why I have inculcated it so deeply in the workings of WAMU in Washington. We devote several full-time employees to produce more than 50 hours a week of live original programming for our multicast channels — bluegrass and Americana music on Channel 2, and news and information on Channel 3. We further demonstrate our commitment to multicasting on our main channel. For the first year after we started multicasting three HD Radio channels, we spent at least 15 seconds of every hour on our flagship signal cross-promoting Channels 2 and 3, and our hosts still give them at least four spots a day. Reminding listeners of the other offerings in our “radio community” requires a sizable investment in airtime, as well as the traffic department’s writing and logging.
