“SCA radio”

This is one of the special radios that is used by reading-impaired listeners who hear my volunteer reading of newspapers. From the FCC, www.fcc.gov/media/radio/subcarriers-sca » “A subcarrier, known also as Subsidiary Communications Authority or SCA, is a separate audio or data channel that is transmitted along with the main audio signal over a broadcast station. These subcarrier channels are not receivable with a regular radio; special receivers are required. Subcarriers are used for many different purposes, including (but not limited to) paging, inventory distribution, bus dispatching, stock market reports, traffic control signal switching, point-to-point or multipoint messages, foreign language programming, radio reading services (see the Policy Statement and earlier MO&O and NOI in MM Docket 87-9), radio broadcast data systems (RBDS), station control and meter reading, utility load management, and muzak. A broadcast station may transmit more than one subcarrier signal. Licensing of subcarrier operations ended in 1983 when the service was deregulated.”

And now I've learned how to include links and bold in the same post…
