■r 20, 1923 RADIO DIGEST — Illustrated PRINCE OF WALE'S RANCH TO GET SET HEIR TO BRITISH THRONE ARDENT RADIOPHAN Will Equip Canadian Farm— Has Desire for Broadcaster at Buckingham Palace, Too TORONTO, CAN. — The "R. P." ranch, tie Prince of Wale's ranch near High liver, Alberta, is to be equipped with one of the best sets obtainable soon according to a statement given Radio Digest by the Prince's private secretary in Winnipeg, prior to the Royal party entraining ior Quebec. The ranch is twenty-eight miles from High River, the nearest town, and on his recent visit to the ranch the Prince missed the use of a Radio set. "The Prince, his father, King George, and in fact all members of the Royal family are very enthusiastic Radiophans," 6aid the private secretary. "They have several sets in their many residences throughout the British Isles and the Prince has a high powered one of his own. He follows with great interest all the activities in the Radio world and while on his trip to the ranch expressed regret that the ranch was not equipped with a high powered set. Prince Wants Broadcaster Too "He stated that before he returns on his next visit he will have one installed so that he can keep in touch with the outside ■world. While in England he has spoken on three occasions at a broadcasting station to hundreds of Radiophans all over the British Isles and has already expressed a desire to have a broadcasting station installed at Buckingham palace where King George and other members of the Royal family can broadcast messages from time to time. "A few months ago a large hosiptal in Scotland was opened by the Prince via Radio. It was his intention to open the hospital personally but at the last minute his plans were changed and he was required to cancel many functions. He was approached, however, and requested to open the hospital by Radio as a large set had been installed in the hospital for the use of the patients." Radio Grows in Britain According to the Prince's secretary, Radio is gaining greatly in popularity in the British Isles. He predicted that this DEVICE GIVES TRUE PIANO TONES ____ : : The remarkable instrument shown in the center insert is the new piano microphone developed and now used by the General Electric Company at their Schenectady station, WGY. Three of the devices are attached to the piano sounding board to pick up the high, middle and low notes respectively. The vibrations of the piano jar the floating armature of the three microphones, which are really miniature alternating current generators of special design. The jarring of the armatures makes^plectric currents that correspond in amplitude and frequency with the original piano tones. These electric currents are then superposed and used to modulate the high frequency carrier wave radiated by WGY. By individual control of each of the three "dynamo" microphones it is possible to blend the low, middle and high notes together so as to produce on the air an almost exact reproduction of the original piano sound winter would see the new science at its height. All British plants manufacturing equipment are operating day and night to meet the demand. Asked if there is much demand for American made goods the secretary stated that as far as he knew there was a better demand for the American made goods than those produced by the British manufacturer chiefly because the American made goods were more up-to-date and comparatively cheaper. He attributed this GIVE that boy of yours the keenest ears in radio this Christmas — the receiving set that brings in the broadcast of half the continent as clearly as it was sent out.

Reduce CHICAGO. — Thousands of Radiophane all over the United States and Canada were agreeably surprised, they reported, when they received recently, more clearly than ever, the programs broadcast by Station KYW of this city. Since May 15, when the wave length of the station was reduced by governmental order from 400 to 345, listeners in experienced difficulty in receiving KYW. The sending power of the plant had been obstructed so as to reduce considerably the area of its audiences. Buildings Absorb Power Investigation by engineers in the employ of KYW showed that surrounding steel buildings, attuned to the 345-meter wave length, absorbed a great part of the radiation. Steps were then taken to correct the condition. A series of tests gradually reduced the amount of sending power lost. But the greatest step forward was that in which Station KYW, by authority from Washington to A. B. Beane, federal Radio supervisor for this district, was enabled to increase its wave length to 536 meters or 560 kilocycles. Marked improvement in transmission was immediately noted by listeners in. The new wave length will be tested during a 30-day period. Asfcyour Dealer (Trade Mark) AUDIO TRANSFORMER $3.50 This little wonder is the surprise and talk of Radio Engineers everywhere.
