Broadcasting Telecasting (Jan-Mar 1960)

NAB ..PREVIEW EXHIBITS CONTINUED A toggle switch triggers zoom lenses. The round-the-clock automation system grew out of a predecessor capable of handling up to 25 switching functions during a 60-second station break, the "panic period" when a variety of slides, film clips, tapes and spot announcements are broadcast. RCA's tv tape recorder now includes a transistorized processing amplifier and expanded monitoring facilities. The new 1 kw BTF-1D and 10 kw BTF-10C fm transmitters are designed for conventional broadcasting and multiplex operation. The 5 kw BTF-5B unit completes the fm line. New high-efficiency circuitry is claimed for the BTA-5T am transmitter, "built to make possible an annual power input saving of 15,000 kw hours in a continuous program operation."
