HIERE is more than one way for a radio wave to get to -Africa. WGY and its shore wave station, 2XAP and 2XAD, have travelled the 8000 miles to Johannesburg direct on many occasions, but according to the "Rand Daily Mail," of Johannesburg, the waye on January 2, 1928, was rerouted by way of Daventry, and a double rebroadcast was accomplished. Daventry picked up and. rebroadcast 2XAl", of Schenectady, and JB, of Johannesburg, picked up Daventry’s rebroadcast, and rebroadcast that signal. The "Rand Daily Mail’s" story, and the heading, "Unique Broadeasting Feat-A Triumph of Relaying," follows: "A unique achievement in the history of wireless reception in South Africa was achieved by JB last night. WGY (Schenectady) broadcast a speeial programme for Europe, which was picked up by Daventry. (England), relayed by this station, and received clearly by JB, where it was again broadeast for the benefit of enthusiasts in South Africa. Thus the American programme had travelled across the Atlantic to England, and from there down to South. Africa, where it was distributed to every listener-in, Other items caught from Daventry by J5 were ‘Fitchy-Koo," from Katinka, and musical selections." TPHuE editor of the New York "Radio News" is optimistic regarding television. He says: "What will happen in the future and during the next eycle of radio progress, no one can foretell exactly; but, for one thing, it is quite certain that during the next two years a new adjunct to radio’s utility will come along in the form of television. You will have a television attaehment, just as you have a laudspeaker to-day, You. will plug it in to your radio set at the same time you plug in your radio loudspeaker ;

and you will see the distant events on your television ‘screen’ as you hear them on your londspeaker, both at the Same time," APPLY a small daub of = rubber cement around the needle shaft of the cone speaker if it has developed a buzz or rattle that is especially noticeable on fairly weak volume. Use the kind of cement that remains seniiflexible after drying thoroughly, and place it at the poit of connection of the needle shaft with the cone tip. On the front side, back off the small nut on the shaft end enough to allow the cement to coat its surface, and dry before tightening the nut, forming thus a rubber washer. After tightening the nut apply one more coating of cement over the nut and shaft end. Do not tighten the nut more than necessary, otherwise it is possible to cut through the first contng. Glue will work satisfactorily for the volume nsually required for Lest reproduction with cone speakers, hut rubber cement is superior when low volume is Cesired, TUE ouly impo.taut wires which ’ must be kept short and free of all others are those running directly from the grid posts of the valve sovkets to related instruments, It is advisable, but not so urgently essential, to keep the grid connections on the audio amplifiers short. However, ii they do take a few twists or lie across some other wires they will not serionsly affect the operation of the receiver, as similarly mistreated wires in the radio-frequency maguifiers are certain to do. All the other wires’ in a set, including the filament re-. turns, the A, B and C battery and rheostat and switch leads, may be bunched together into one cable without harming the ontfit in the slightest. There is no nced at all for stiff bushar and carcfully separated connections; insulated solid or flexible No, 1% wire is just as good and can be handled much more easily, AN outdoor aerial must not touch anything unless it is an excellent insulator, and the faver points it touches, even though they are insu. lators, the better the aerial installation and the more energy comes to the receiving set,

"The rapid advance of broadcasting will, one feels, continue for many years to come, there being still many fields of activity as yet uncovered-espccially the field of internatinoal relays (says the London "Radio Times"). European broadcasting authorities are patiently working to make possible a great ‘link up’ of the nation’s programmes by means of telephone lines. This is intricate work, for it means the installation and connection of lines of a special weight jand frequency. Such a connection be‘tween London and Vienna is now almost 'complete-and the day not far distant 'wheri we shall be able to receive the Viennese programmes broadcast from our British stations." | Almost every cirenit in some American radio publications is now arranged for A.C. power for plate, filament, and grid voltage. Dr. Lee Forest commented recently that Australia and Great Britain have not progressed as rapidly in radio as America.

A broadcast listener writes from the Swiss Alps to the London ‘World Radio" :-"Listened to the passing of the Old Year and the entry of 1928 from many different stations. At mids night (11 p.m. G.M.I.) I held myself in readiness for a busy five minutes, and on the sound of the first chime of the hour commenced my rapid search, Within a very few minutes many studios lad passed through my, loudspeaker, First came trumpet» calls from a church steeple in Breslau. Then I found the orchestra from one of the Polish transmitters playing Chopin’s famous ‘Military Polonz.ise’ (Opus 40), bells again from ‘Vienna; and on running 1ouxl the German stations found nearly all of them play, ing ‘Deutschland uber Alles? After listening for a while to the different broadcasts I turned back to the homes land for a few minutes at the Savoy, Hotel, and ended the sitting listening to the beautiful Watch Night Service from York Minster." _ a
