Llgh! and Power Man Explains
 Origin Of Interference

Ull8ll Ol interference
 An interesting and educational story of the causes of radio interfer- ence and what the electric compan- ies are doing to eliminate unneces- sary noises and static and help the radio owner to solve this perpleXing problem. was told this noon by Benjamin H. McElhone. district manager of the Connecticut Light &; Power Co.,. at the regular meeting of the Rotary club at the Rurritt hotel. The speaker although limit ed by time. gave a concise idea of the causes and opened vista to the average radio owner to successful elimination of the many and varied harmonies and disharmonies not in- cluded in the radio programs.
 ''Our engineers have made thor ough investigations of the interfer- ence produced by causes other than radio itself" the speaker said. Ut was soon realized that most of the eXtraneous noises coming out of the speaker were not only annoying and detrimental to radio, but were pre- ventable. Likewise it was discover cd that static had been blamed for many disastrous attempts at recep- ton. when as matter of fact it was nowhere in the picture.
 "If Sonn hoca,,o o,;Jo,k t., %1,o tabulation of statistics that most of the complaints regarding loud and painful noises might be placed in the same category as that of the dog that sat on his own tail and howled. but was too lazy to move. Briefly, let us consider the cause of bowling, humming and all the rest of the vol unteer symphony. Our records com- piled from typical investigations show that weather conditions, static, howls in the set, two or more sta- tions operating on the same wave fective electric equipment in the home and defective elctric quipment outside. are all contributing causes. More than five hundred complaints were investigated from January to 1 October S1st, 1928. requiring one or locate them. Tabulation of the com plaints show these results:
 45h per cent due to lighting con- pany equipment: 401a per cent due to defects in radio set or equipment i'll home of owner making complaint: :: equipment and exterior causes over which the company has no control. per cent. unable to locate or clear ed before our investigation.
 True the largest percentage of complaints show our equipment to have been at fault, but you will note that 51 F per cent were due to causes over which we had no con- trol.
 investigations conducted in other cities of Connecticut, also New York, Chicago and Dayton confirm this ratio of percentages. To the radio public it may seem logical enough that power companies should burn coal at present prices just for the fun of pumping current through holes ip the lines to ground. But they don't. They would rather sell electricity than broadcast it.
 Your lighting company will con- tnue as in the past to investigate and clear all our equipment found defective or causing interference are so numerous that one blushes to cnumerate them. But. oddly enough though they are legion and general. ly unsuspected, most of them can be eliminated in few seconds, with nc great demand for skill or knowledge of electricity and at a small cost.
 "A concerted drive by the inter ested public would put most all ol these nuisances out of business ovel night. Greater appreciation by tho public of their duty in this work ant the assurance beyond reasonable doubt that the trouble is outside jthcir homo will result in bette1 radio reception for every user.
