r" tive competition ” By Capt. Robt. Scofleld Wood. (OD. F. C., M, C., Croix de Guerre with four palms; formerly Commander *M7th Squadron, Royal Air Forces.) RADIO HELPS SOLVE UNEMPLOY. MENT PROBLEM. Factories that have. been standing {do ‘for months and some which closed down shortly after the armistice was signed ure taking on a lifelike aspect again. ‘These plants are being used to manufactiire radio equipment and ar: running on an eighteen-hour schedule More places are opening every day. Manufacturers who were engaged {i @ther lines not quite so profitable are converting their plants to make radlo parts. Many electrical manufacturing plant? have been enlarged to try and beep pace with the ever-increasing or- @ rs. ‘All of these new operations, enlarge- ments and conversions have made pos- sible employment for thousands all ever the country and in some sections have taken the edge off the unemploy tent situation, which was getting eritical fi Another slant on this situation is that among other things it is also soly- fmg the shortage of radio accessories; @nd while most manufacturers adinit @hat they are several months behind their orders things are taking on a much brighter aspect. It looks as though these newcomers in the field were going to upset all previous cal- eulations on the graph of demand and supply and give the industry that much needed stimulant—competition, PRESIDIO'S NEWS STATION NOT HEARD HERE. The United States Army — Signal Corps’ new radio station at the Pi @io Reservation near San Franc which commenced operations on the 1Gth of this month, has not been heard Wy the New York Signa] Corps station ‘wp to the present time, according to the radio officer in charge of the East- ern station. : This new West Coast installation is reported to be one of the most power- ful assemblages in the service, and @irect communication with New York and Honolulu has been planned as part @ of {ts daily performance. MAYOR HYLAN IN COMPETITION WITH REGULAR PROGRAMME. The speech Mayor Hylan delivered Yast night from the Western Electric Station on West Street was not taken Kindly y the fans. The Mayor's Gubernatorial aspirations are not at all interesting at this time of the year, and particularly when run in destruc- to a perfectly good ‘oncert. If His Honor wants to be heard over the radio phone why not have some special wave th as- wigned for the occasion, so as not to conflict with the regular programmes that are enjoyed by hundreds of thou- gands every evening. For such gala oceasions a wave of 450 meters would Yeave a nice margin between the grammes, and all those who care to Usten to either may do so without In- terruption from the other by merely thanging their wave lengths. It is hoped that the Mayor will take Into consideration these things the next time he decides to deliver a radio phone message and give those who are not §terested in politics an opportunity to @joy the evening unmolested. TO COMPUTE NATURAL WAVE PERIOD. Questions concerning the natural wave length of aerials are always to be fougd in the daily mail, Because of our limited space we are forced to jswer them coliectively. ‘The natural period of vibration, or ‘wave length, as it is called, can be ap- proximated by adding the length of the gerial, the length of the lead-in and the ground connection and multiplying the total length of all three by 4% and @viding by 3. For instance, an aerial 120 feet long with a lead-in of 30 feet and a ground of 18 feet has a total length of 168 feet. To find the natural wave length multt- ply 168 by 4%, which gives a total of R68 feet. Divide this by 3 to change it ‘approximately to meters. This gives the natural wave period of 252 meters. ‘This holds ‘true for single or double wire’ horizontal or vertically swung aerials of the inverted ‘‘L" type. In computing the wave of the T or um- Qrella type multiply by 6 instead of 4% and proceed as above, TO PROTECT THE RECEIVER. ‘The action of lightning is one thing which science will not definately try to define. It has a general trend toward certain actions but can never be de- pended wpon to do the same thing twice under apparently similar conditions. And because of this uncertainty it is ‘always wise absolutely to disconnect your instrument during a thunder storm. All that is necessary is to loosen up the aerial binding post and pifll the lead-in wire away from its connection and let it hang loose and away from the instrument. ‘Lightning usually takes the most di- rect path to the carth, but it does not necessarily follow that it will always follow this rule. So take every pre- caution to protect your apparatus, AN INTERESTING EXHIBIT.
