RAD|OPHONE PATH
 TRIANGULAR ONE
S60 Miles of Land Wire and
 6,SO0 Miles Of Ether
New York, Jan. P-The radio

New York and London yesterday went over $50 land miles of wire and $500 miles of ether path, com- ing and going. | The circuit involved describes a triangle, with it's broad base resting at Houlton, Maine, and New Torn city. Between these two points are land wires, carrying London's mes- saages into New York. There are two imaginary lines go- ing out of the United States north cast to peak in England. One is 5000 meter wave length. The other is short-wave of 9 meters.
 The 5000 meter wave goes over the telephone wires to Rocky Point, | Long Island. At Rocky Point rise the delicate tracery of antennae, and six towers, 1,250 feet apart. There is a Cooper house" at the base of each of the towers, and in the cop- per houses are the tuning coils for the radio telephone. Here the voice is projected along the imaginary line to Wroughton receiving station, in England. There land wires carry the voice into Lon don.
 Tlle parallel line on Americas southern side of the triangle circuit. | and using the short wave, starts at | Deal Beach, New Jersey. There the voice is picked up from land wires out of New York. From Deal | Beach, the shore wave passes by the | Wroughton receiving station without repeating and is picked up at Lon- don first hand.
 Both long and short waves arc rushing eastward simultaneously l and London, getting the product of l the two may tune out which ever is weaker or static-affected. London, having no short wave | sending equipment al present, sends it's voice over land wires to the Rug | by radio transmitting station, where | it is shot northwest to Maine, cut | ting across Ireland to get there. Equipment used represents $5.- GOO, ,000, an outlay covering many | years.
 The high power radio telephone transmitter is declared to be a mar vel of technical cooperation. To bring it to its present state the la 1 boratories of the A. T. & T. com pany have utilized the services of hundreds of it's 5000 technical en- gineers.
 To the layman, the room at Rocky Point where three banks" of voice simplifying tubes are housed might appear somewhat like an engine room. Spotless glass, steel castings, dials, levers and other parapherna lia of an engine room grace the sides of two huge boxes, containing the high power water cooled amp:i- fiers. Behind these is a circular bank of 15 water cooled power ann pliier tubes
 Then there is the low power DOT tion of the transmitter, with its speech input. modulating filters and amplifying apparatus"
 Similar equipment has been in- stalled by the British post office at it's rugby transmitting station.
 To the telephone user, the miracle of trans Atlantic speech is likely not comprehensive technically. He takes down the receiver, asks for a num- Der, and shortly later is talking from Broadway to Trafalgar Square.
 A girl. seated before a switch board, can effect the connection. with no more effort than ringing up a suburb.
 Behind these external simplicities however, were problems, each one of which took years of experiment. They were:
 The problem of suitable appara- tus and systems for putting the voice waves into such Q condition that they may be radiated into space.
 Suitable apparatus and systems for receiving the voice waves from space.
 Apparatus for separating differ ent radio messages and providing secrecy.
 The study of transmission char of the space through which the radio waves travel.
 Today the problem of static" a sputtering demon, has not been wholly mastered, and secrecy of is not entirely h. sured.
 But sending apparatus and re- Ceiving apparatus, engineers say, have been brought to high point of development.
 In a mans hand now, an object only a few pounds may be held, 23 of which so amplify the voice as to make transatlantic communication possible. It is that water cooled tube used in three stages of amplification. Twelve years ago, it took 500 tubes to send ong distances, and the effect was only promising.
