Show WIRELESS PHONE USED ON AUTO Highly Interesting and exhaustlvo experiments. .Involving for the first J time the use of the automobile in wireless telephouy, have recently been made by E C Hanson of Los Angeles. ' J One of the most recent experiments experi-ments was receipt on Lookout moun- I I tain of a message sent over the ranges from Long Deach. thlrty-flv miles away The car used was an R-C-H 1013 tpe, current being supplied sup-plied by the lighting storage batterv. with which tho car is equipped ' Strapped to front and back of the I car were sectional poles supporting ' aerial wires and high oltago insu-i lators tuned to definite wave. These wore able to pick up waves propagated propagat-ed through space nt rate of J.SC0001 miles per second fiom the Bending ' station, these waves Impinging on the I aerial wires on the car, oscillated j through the primary colls of the tun- er to tho earth connection, thus set- ' ting rp surges of electric energy of ' varying amplitude, corresponding to tho voice at tho transmitting station sta-tion Vibrations In tho secondnry coll actuated a very delicate crystal detector, which In" turn charged a conuenser ami discharged through the ( ! delicate wireless tolenhone receivers, held to the ear of the occupants of i tho car. Every modulation and variation in i tone from the transmitting station I caused a similar svnochronous cur- j rent at the receixing station on the j car, resulting In transmission of ar- , ticulatcd speech nnd music through a. space of raoro than thlrtv-fle miles from sending station to enr So excellent were the results obtained ob-tained and so pleased was Mr Hanson Han-son that on the return to Los Angeles An-geles he predicted that It would not be long before wireless telephones would be regular equipment on automobiles. |
