FCC Seeks Comment on AM IBOC

FCC Seeks Comment on AM IBOC

The FCC has, in record time, sought public comment on the report by the National Radio Systems Committee about Ibiquity’s AM IBOC system. The NRSC’s report evaluates the lab and field-testing of Ibiquity’s system in the hybrid mode.
The comments are due by June 18 to MM Docket 99-325.
Additional testing is required to assess IBOC’s performance during AM nighttime skywave propagation conditions and when Ibiquity finishes re-doing some tests with its Perceptual Audio Coder or PAC. Earlier tests were conducted with its former codec, AAC. The commission will seek further public comments when it receives the results of the additional tests.
