11/24/36 "This new transmitter is similar in its general features to the D-96847 but the use of alterna.ting current for the filaments has made it possible to eliminate the motorgenerator set. Its place is taken by simple transformers to reduce the alternating current supply voltage to a proper value for application to the filaments. Transformers are not only much less expensive than motor generators, but require no atten¬ tion during operation, and their use therefore represents an appreciable simplification. A further distinguishing feature of the new transmitter is the use of the 315-A mercury-vapor rectifier tube in the high-voltage rectifier circuit. This rectifier employs six of the 315-A tubes, and is rated to deliver 1.7 amperes at 11,500 volts. This is the first application of this low-priced tube, which is designed primarily to reduce the cost of furnishing direct current at voltages as high as 12 kilovolts. "Another simplification in the new transmitter is the omission of the one-kilowatt amplifier unit. One complete unit, including tubes and power supply, has been omitted, thus lessen¬ ing the cost of the transmitter and decreasing the space required. "Only twenty-seven tubes are employed in the complete transmitter, which represents a substantial reduction as compared with other equivalent transmitters.

The 50-cent distribution made on July 1st was the first payment since 25 cents was voted on July 1, 1935. XXXXXXXX WXYZ, NBC-Blue network station in Detroit, has begun construction on a new, 474foot vertical antenna. The new structure will mean wider coverage for the station, and also a better signal in Detroit, its suburbs a.nd surroundings. XXXXXXXX 11
