A REVELATION IN RADIO RECEPTION

Missed words, slurred and blurred notes, harshness of tone; how often these things spoil a wireless evening! And it becomes a matter for wonder that they are tolerated once one has heard the perfect reception that firstclass wireless apparatus gives. Such an opportunity was provided yesterday by a visit to the Philips Radio Exhibit at the Winter Show, where a convincing demonstration of the quality of Philips valves and loud speakers is given. The music of an ordinary Cheap gramophone is taken straight from the tone-arm through Philips valves to a Philips loud speaker. An excellent test of the reception was provided by a set of records on “The Instruments of the Orchestra,” in which the instruments play solo in succession. Of such crystal purity was the reproduction from the Philips loud speaker, that even the untrained ear could detect the difference between the music of instruments so much alike as the violin and viola, the piccolo and the flute. On turning one’s back it was hard to believe that the music was not coming from the actual instruments instead of from a loud speaker. In face of such reception one cannot avoid the conclusion that many of the faults blamed to atmospherics and faulty transmission, are really due to indifferent valves and loud speakers. It should not be overlooked that a Philips battery eliminator and a Philips transformer were used for the demonstration apparatus.
