Briefly, the system used for this (called in technical circles "multiplex stereo") consists of a coded signal combined with the station's regular broadcast. And unscrambler attached to your FM set (called a "multiplex adapter") will allow separation of the two stereo signals, which are then fed through the system as any other source would...
...need for civil defense preparations; THE NATION'S definitive report on the military and political decisions during World War II that led to the partitioning of Germany; THE WORLD'S report from South Viet Nam on the renewed jungle warfare in South Viet Nam, which may signal a new Communist drive in all of Southeast Asia...
...believes that the attack may well be the signal for a new Red drive against South Viet Nam, part of an overall, constant movement to infiltrate and encircle the whole area (see map). The Viet Cong guerrillas get their seasoned cadres and supplies from Communist North Viet Nam via the Ho Chi Minh Trail, which parallels the borders of neighboring Laos and Cambodia.

...obvious improvement over recent AM-FM experimental broadcasting in stereo, by which a station would broadcast the left signal on an FM frequency and the right signal on an AM frequency; the listener needed a separate radio for each signal, and, moreover, received poor-quality stereo because ordinary AM radio has a limited frequency range and is subject to static and other kinds of interference. MPX, on the other hand, uses a single transmitter that carries two sets of signals simultaneously to a single FM stereo tuner. The main carrier contains a combination of left and right (L+R) signals...
