The 83 exclusive wavelengths have been shared out to the various countries according to the following list: Albania, i; Austria, 2; Belgium, 2; Bulgaria, i; Czecho Slovakia, 3; Denmark, i; Esthonia, i; Finland, 2; France, 9; Germany, 12; Great Britain, 9; Greece, i; Holland, 2; Hungary, i; Ireland, i; Italy, y, Jugo Slavia, i; Latvia, i; Lithuania, i; Luxembourg, i; Norway, 3; Poland, 4; Portugal, i; Roumania, 2; Russia (West), y, Spain, y, Sweden, 5; Switzerland, i.
The area coming under the jurisdiction of the Office is bounded as follows: On the North, by the Pole; the South, by the Mediterranean and Black Seas; the East, by a meridian drawn through Eastern Russia; on the West, by the Atlantic Ocean.
There are some two hundred broadcasting stations in Europe either active or shortly to become so, thus it is apparent that the common wavelength channels will be shared by about seven stations each. However, some of the common waves are shared by only two stations, according to the list drawn up by the Geneva Bureau, while other common waves are shared by as many as ten or so stations.
BRITAIN'S INTERPRI-.TATION OF Tin; PLAN
LEI us see how the new plan affects — Great Britain, for example. There are twenty-one broadcasters in that country, this figure including Daventry, the high power long-wave broadcaster, 5 xx. This latter will not, of course, be affected by the "Geneva Plan." Of the remaining twenty B. B. C. stations, 9 are main stations employing a power output of from 1 500 to 3000 watts. The other 1 1 are relay stations using about 200 watts, and are for purely local service. Every B. B. C. station, until the "Geneva Plan" came into being, used a different frequency. Under the new regime, Great Britain has been given nine exclusive wavelengths for the main stations, the supposition of the Office de Radiophonie being that the B. B. C. would choose to operate all of its relay stations on common wavelengths shared by other nations.
Captain Eckersley, the chief engineer of the B. B. C., has decided not to do this, however. He has made up his mind that it would be better for the B. B. C. to reserve one of its exclusive wavelengths for the use of nine of the eleven relays. The other two relays will operate on common wavelengths, allotted by the Office de Radiophonie. This plan leaves eight exclusive wavelengths for the use of the nine main B. B. C. stations. Aberdeen and Birmingham will therefore share a wavelength, the other B. B. C. main stations being operated on the remaining seven exclusive wavelengths.
Captain Eckersley's plan was formed to obviate the necessity of some of the relays working ashighas 1200 kc. (2 50 meters), a frequency which he considered would be too high for many of the receivers to tune-in. By his revision of the "Geneva Plan," he displays no lack of confidence in the Office de Radiophonie's original allocation. The Office, when allotting waves, unnecessarily specified which individual stations should operate on the exclusive waves given to the various countries, to simplify matters. Captain Eckersley is simply re-allocating the waves given to Great Britain among the stations in the B. B. C. chain. He is not taking any frequencies not allotted to Great Britain. In fact, if his plan of stacking most of the relays on one wavelength works, it will leave the common waves allotted for those relays freer for other uses. On the other hand, severe interference may be encounted by stocking nine relays on one wave, in which case the only remedy will probably be in utilizing all of the common waves allotted by the Office de Radiophonie for site relays.

See that rubber jacket about to descend on the "howler"? Once this "howl absorber" slips over a tube the howl stops for once and all!
No more ruined reception. The thick shield of live rubber effectually soaks up the trouble-making vibration.
You can get it for every size tube ! Just ask your dealer, or write.
