The Wingham Advance Times, 1925-06-18, Page 7harsclay, jun xfithe tg2 WAVE LENGTH AND FREQUENCY By R, M, Sherrill (Radio Engineer) In radio work we have become ac- customed to designating the electro- magnetic waves from the transmitter, by giving the length of the wave in meters. The meter is an European unit of length which seems to have been universally accepted in radio cir- cles. It would be just as accurate however, and just as logical, to meas- ure the waves in miles, yards, feet, inches, or any other unit of length, There is however, an entirely ti f- ferent way of designating radio weav- es, which for everyday use, as well as for .scientific purposes, is mach more useful. This way designates the wav- es according to their frequencies, .1. e. -the number of cycles or oscillations that they go through in one second of time. As the number of cycles per second runs up into pretty large fig - tires, the frequency is generally given in kilocycles, which are units of r000 cycles each, The ,each, is an illustration of how the frequency of a wave is a bet- ter term to use than the wave length: Suppose that a person says "his re- ceiver will separate two stations which are only 5 meters apart" This is not a logical or a complete state - anent, as 5 meters difference around 200 meters represents over 8 times the separation that 5 meters difference does around 600 meters. If the per- son had said that "his receiver had separated two stations which were, say 3.5 kilocycles apart" -his state- ment would have meant something, because •3.5 kilocycles represents the same separation no matter what the wave length ,happens to be. Practically all call books are now giving both the wave length in meters and the frequency in kilocycles for each station. Even the newspapers, in their published programs, generally give the number of kilocycles in par- enthesis after the wave length. In the writer's opinion, it is only a matter of time before the waves are more generally expressed in kilocy- cles than in meters. If you wish to keep up to date inradio, start using the. term'. "kilocycle" in preference to meters. To find'the number of kilocycles, when the wave length is given in me- ters, divide 3oo,000 by the wave length. -0_- Broadcasting Operator's License Until recently, the operator of a broadcasting station was required to pass the same examination and obtain the swine license as a cornrnercial code operator. A new license is now authorized, which is for the operators of broad- casting stations only. The examina- tion for this new license is just as se- vere as for the old commercial lic- enses, but is more on the special re- quirements of a broadeast station op- erator. In'the code requirement, for instance, the applicant for this new License needs to receive but -x2' words per minute against the 20 words per minute which were previously requir- ed. The theoretical part of the exam- ination xamination is more severe, however, and the applicant must make a grade of at least 75 per cent to receive a license. -0--- What Does It Mean? A communication from a reader is as follows: "Dear Radio Editor: I have a neighbor who admits that he is' the bee's knees' when it comes to `doing anything with radio. What does it 'mean, when I ask him how his newly constructed 8 tube receiver works, and he answers, 'Oh wonderful. These local stations come in something won- derful, so nice and clear to! ' " _0 - Large Scale Radio Laboratory Radio enthusiasts throughout the world are interested in the enormous radio laboratory being erected by the General Electric Co,, near Schenecta- dy, N, Y. This laboratory, which covers a fif- ty acre field, is to be devoted chiefly to transmitting experiments. Three goo foot steel masts are being erected and numerous wooden ones are to be built as required. Elaborate power plants, equipped tosupply various vol- tages, currents and powers, form -a part of the scheme. Improvements in both transmission and reception are sure to.follow from such large scale investigations. -0- Storage B Batteries Wherever possible, the storage B batteries should be kept well cover- ed, in order to keep out dust and dirt. The moisture, which always collects on the tops of the cells, makes the dirt stick fast, and soon there " is II�IWIIIalila111�9111�Ifl1cimmill , IIIaIIi�1111itllll611f�III�IiIIi111 IIla1U®JU�Iumm ! mum' min i This is the time to buy your next Winteli'9s CoaL Fill your bins noir a d av,.id i the high prnaaP of Coal later a in time year. i 1 Best D.

Write him in care of this paper. L, E. B. says;-" T have just com- pleted a 2 tube tickler regenerative set _using 2oIA tubes. The set does; not .oscillate very strongly, however, and will not work well at all on some wave. Can you give' me a hint as to what the trouble is?" Ans.-You do not mention using a by-pass condenser across your B bat- tery and the primary of the amplify- ing transformer. The lack of such a condenser would cause trouble such as you describe. --.0--- G. B. says: --"The crystal in my de- tector is quite old and there Are not very many sensitive spots on it any more. Will it •heipeto scrape off the surface of the crystal with -a knife or a file?" Ans.-No. You will get a more sensitive surface by breaking the cry- stal open with a hammer and, using one . of the new surfaces thus formed. Wiles; far the By Betty Webster A Sewing. Hint To avoid puckering sheer material: With some material such as muslin or crepe de chene it is almost impos sible to stitch it without puckering it. This can be(avoided by placing a piece of . paper under material while stitching and sew seam. When finish- ed it is a very simple matter to tear paper away from seam. -o- Hints For Women While Touring 1. Do not worry about your dress. 2. Dress as naturally as you can in order to feeI'comfortable. 3. A little hat is better than 'a large one. 4. For hot days -a thin dark dress can be worn anywhere at almost any time and is preferable to the heavy suit, motor coat and veil of the old days: COOKING.

He noticed more clearly, we hope, Through the Walkerton Telescope. All its spots, stripes and checks. A Kitchener Record he kept (While the Lucknow Sentinel slept) Of each thing he saw.

"'Tis sure Chesley Enterprise, this," The Examiner said, "Oh, bliss! We will print it, I guess." Now what did the Citizen see - As it gazed at the Sun in glee And continued to scan, it? A Goderich Signal, you say? Or a Southampton Beacon? Nay nay- 'Twas a Coldwater -Planet. _NEWS PAPER:DOMBELL Of course he's right. The sun is a Coldwater Planet.
