niiiiiiiniiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiuiiiuiiiii NOTES AND NEWS. j “ I Week-end Reception. Saturday.—Nothing startling. The ether was fairly quiet and the New | Zealand stations functioned as usual. ; The Australians were very weak, 2BL ; being the only one to make itself aud- I ible. Fading and slight distortion noted on all stations except 3YA. The short wavers*were up and doing at good strength but in every case light static and pronounced surging slightly marred reception. Radio Manila put on some nice musical items. Zeesen, Amsterdam, Kootwijk and Sourabaya continued their duplex telephony tests, only one announcer failing to yell at the other. fellow. No trace of RA97. Sunday.—Probably due to the cyclonic conditions that ruled, reception of 2YA during the afternoon session was badly distorted. The evening transmission was much better. Fairly good reception of 4YA was recorded. A trifle of distortion was noted occasionallv. Ether very clear. 1Y A almost inaudible at 8.30. No static. Closed down at 9*30. **2YA was then going well. Gave the Australians the “ once over.” Heard little, but another listener states this morning that “ The Aussies from 7L down romped in on a two-valver.” There must be something wrong with “ Horace.” RADIO IN 1929. Events at Home. The Baird Co. gave demonstrations to a Special Committee and the P.M.G. recommended that the 8.8. C. should offer facilities for experimental television transmissions. There was a failure to reach agreement between the 8.8. C. and the Baird people regarding the times of transmissions. The 8.8. C. were unable to offer more than three-quarter-of-an-hour periods per week out of programme hours. Eventually, experimental transmissions were arranged on the basis of five peiods of half-an-hour each per week. The new high-power broadcaster at Brookman's Park,, which is to be London's Regional Station, started experimental transmissions. Work was commenced on Broadcasting House, the new headquarters of the 8.8. C. The Prague Plan of wave-lengths allocation was brought into operation. 8.8. C. Resignations. Captain P. P. Eckersley, Mr R. E. Jeffrey, Captain West, Mr K. A. Wright, Mr Eric Dunstan and other well known 8.8. C. officials resigned. Captain Eckersley joined the staffs of “ Popular Wireless,” “ Modern Wireless,” and the “ Wireless Constructor.” It was calculated that in 1922 there were 30,000 radio receiving sets in use, and that the trade turnover was about £500,000. At the end of 1928 the turnover for the year was reckoned to be £25.000.000, and the sets in use 3.000,000. Professor E. V. Appleton, Professor of Physics, King’s College, London, disclosed details early in the year of his Heaviside Layer experiments. Fie was able to penetrate this with very short waves and located another similar layer many miles above it. Marconi Royalties. I The Marconi royalty question was thrashed out in Courts of Law and, after several interesting phases, an agreement was reached between the Marconi Co. and the R.M.A. on a 5s per valve royalty basis. Contracts are to b 6 for five years, the trade benefiting by getting the use of a very large number of existing patents and of any future patents eventuating in this period. Broadcasting played a leading part in the General Election. There were preDissolution speeches by all parties and the results were broadcast far into the early hours of the day following polling day. Better valves than ever became available for listeners and constructors, notable newcomers being the remarkable Cossor New Process Valve. Portable Sets. Portable sets attained a remarkable popularity, which shows no signs of waning. The combination of electric gramophone and radio set in the one instrument has created great interest, and manufacturers selling them report heavy demands. Attention was at last turned by the listening public to the electric-supply mains as sources of radio power. The result has been exceptionally good trade in all kinds of mains devices. A long-standing difference between the important cable companies (Compagnie Francaise des Cables Telephoniques and la Compagnie Radio France, Cables P.Q.) has been removed by what is described as a “ co-ordination of technical means.” Railroad Radio. The Federal Radio Commission of U.S.A. allotted five short-wave channels especially for use in connection with railway trains. The Brazilian Government has made it compulsory for every vessel leaving a Brazilian port to be equipped with a radio set in proper working order. Unless this condition is complied with the clearing of the vessel will be refused. Radio developments started taking place very actively in Russia. A party of Soviet engineers went over to New York to engage in Technical Conference with the engineers of the Radio Corporation of America. It was announced that five new-Rus-sian stations are in the course of constuction. New Broadcasting Stations. New broadcasting stations were being built in practically every country. The Czecho-Slovakian Government placed orders with the International Standard Electric Corporation of Prague for a broadcasting station which it is expected will be the largest in the' world. The new station will have a power of 120 kilowatts. A German wireless company secured a contract from the National Government of Nanking for the erection of high-power radio stations in Canton, Tientsin. Shanghai, and Hankow. Mr Aylesworth. President of the National Broadcasting Company of America, paid visits to England, France, Germany, and other European coun-

tries. His object was to endeavour to arrange an ambitious scheme of programme exchanges on an international basis. It is calculated that the N.B.C. chain of broadcasting stations serves 50,000,000 American listeners.

A Radio Museum. What was claimed to be the very first museum devoted entirely to radio was opened in America. Great strides in the development of broadcasting were stated to have been made in Sweden, it being reckoned that there are now 66 sets per 1,000 inhabitants. Radio-Paris and Radio-Toulouse were voted by French listeners as the two most popular stations in France. Bordeaux, Sud Ouest, Limoges, Nimes and Toulouse P.T.T. were found to be of little interest. WIRELESS FOR BEGINNERS. No. 84. Well, after the fortnight’s holiday, we can resume our study of wireless with fresh zest. You will recollect that, in articles 82 and 83 we went into the construction of a telephone unit and had reached the point where the vibrations of the ’phone’s diaphragm might, under suitable conditions, be audible to However, that’s not all the story. Consider what occurs when you listen in, through a ’phone head-set, to a spark transmitting station. As you know, the “ spark ” takes the form of little bursts of alternating current but, unfortunately, these bursts are each of the frequency of a million a second—more or less. If the ’phones were connected across a plain coil (an inductance) with only the aerial and earth connected thereto, the spark bursts would fail to make themselves audible for the reason that the frequency (rate of vibration) was too great for the diaphragm to record—or, better, too great to actuate the diaphragm audibly. There is, as you know, a limit to the rate at which any metal diaphragm will vibrate; the spark bursts are beyond that limit. The “ push and pull ” effect of the alternating current (of the spark) is of such a high rate (frequency) that the net result on the diaphragm is no movement. Here is where you are introduced to the word “ valve.” Not the “ toob ”of the Americans nor the little glass gadget in your set that lights up (or doesn’t! ) when you ** turn on the juice.” This valve is a mechanical one required for illustration purposes. Suppose you dug a ditch say 20 feet long by a foot deep and a foot wide and that you could cause water to rush to and fro, from end to end of the ditch. Right. Let that represent alternating current in wireless. Suppose the to and fro movement terrifically fast. There you have the equivalent of the spark bursts. Now suppose you hang in that ditch a trap-door so fixed that it will open, say, to the left, allowing the water to flow that way, but when the water rushes to the right end of the ditch, the trap - door shuts closes —thus preventing the water from flowing to the right end of the ditch. That trap-door is a valve. It opens one way only: it permits the water to flow to the left every time there is a rush of water that way, but opposes any rush in the opposite direction. Get that? Your valve is what is called unidirectional. (To be continued.) STUDIO NOTES. N.Z. Stations. At 2YA this evening Mr H. C.
