Starting in Seattle early next month, Harris Corp. will sponsor a series of “roadshows” about IBOC digital radio in the six cities designated by Ibiquity Digital for its initial rollout. The manufacturer hopes to attract general managers and radio executives as well as engineers to the one-day presentations. Topics include business models as well as technical discussions. Representatives of Ibiquity Digital and Impulse Radio will take part. The first seminar will take place in Seattle on Sept. 10, two days prior to the NAB Radio Show. Subsequent presentations will be made in New York, Miami, San Francisco, Los Angeles and Chicago. Info or to register: www.harris.com.
