notes: label: Description (Brief)
content: An old exhibition label reads: "In March 1934, the Buffalo Evening News which operates the broadcast station WBEN began experiments with this transmitter, as W8XH, to determine the practicability of commercial broadcasting on short wave. In April 1935, W8XH (41 megacycles) was on the air five hours a day with good reception reported from the entire Buffalo city area. The advantages of short wave broadcasting, in addition to extending the broadcast band of wave lengths, are low power and cheapness of operation, freedom from static and fading, simple and cheap antenna installation, and the opportunity to profitably employ station personnel and studio on short wave local broadcasts while the long wave transmitter is occupied by chain programs. This transmitter is a conventional modulated oscillator employing two "800" tubes directly coupled to the two wire transmission line. Operating on 700 volts, the power input was about 35 watts. The antenna, located 300 feet above the ground, was a vertical, half-wave radiator fed in the center through a quarter-wave coupling line acting as a matching transformer."
