The FCC has clarified that stations using the Ibiquity Digital IBOC system may apply for experimental authorizations to split their digital signal into multiple channels. The commission notes in its Public Notice that "several" public radio stations have tested the concept, although the agency is not restricting multiple channel use to noncoms.
"We ... recognize that the extremely encouraging Tomorrow Radio test results establish the feasibility of multiple audio transmissions in the hybrid mode," states the commission.
To apply for an experimental authorization, stations may file an informal application, such as a letter. The FCC staff normally approves such requests within a week, the agency said.
While NPR had hoped the commission would expand the digital notification procedures to include multicasting, the agency said that doesn't fall within the current IBOC Report and Order allowing interim operation in the hybrid mode.
