Abstract
ACCORDING to an article in World Radio of January 10, the 75,000 ton Cunard–White Star liner, the Queen Mary, will possess wireless equipment in keeping with the high reputation she has already acquired as a modern trans-Atlantic express liner. The transmitting and receiving rooms are on the boat deck and separated by a distance of about 250 feet. The four transmitters are operated remotely from the receiving end, which acts as the control room for the whole of the ship's radio equipment. This room contains eight operating positions, the radio-telephone exchange and the emergency installation; and it is in direct telephone connexion with the bridge and all other important positions in the ship. The various services to be undertaken by the Queen Mary while at sea will involve the use of thirty-two wave-lengths, eleven of which are for short-wave telegraphy, nine for radio-telephony, seven for long-wave and five for medium-wave telegraphy. By co-operation with the British Post Office and the International Telephone and Telegraph Corporation of New York, two-way radio-telephone conversation to practically any part of the world will be possible at any time; and two independent conversations may take place simultaneously with the aid of the usual devices for ensuring secrecy. This service will be available from any one of the five hundred state-rooms, each of which is fitted with a bedside telephone, while for passengers in all classes, numerous telephone booths in various parts of the ship will be available. In addition to the apparatus for normal radio communication, a music- and speech-amplifying installation is provided for the simultaneous relaying of three different programmes in the public rooms through thirty-eight loud-speakers. An extensive library of gramophone records of all types will be carried in the ship to supplement the orchestral music and broadcasting programmes normally provided.
