Wireless Wanderings

LiIGH8ts will soon be installed on all radio masts of the Radio Corporation of America to safeguard aviution. The corporation has previously refused to do this, but has now decid= ed to spend £25,000 if necessary to install danger lights on its towers. This decision was come to in view of the exigencies ef the situation, for the failure to light the thirteen 400 feet masts at New Brunswick has been a menace to all pilots flying the air-mail course. BY the use of headphones and a spe cially constructed microphone, an experimenter has listened to the sounds made by grubs while devouring apples. It is understood that the noise they made in spitting out the pips came through at loudspeaker strength. T a meeting of Hamburg shipping companies it was stated that technical difficulties in the way of wireless telephonic communication with ships at sea had been removed, but there were still obstacles in the way of fitting passenger vessels with the necessary telephone apparatus on account of expense. Experiments are nuw being made with fishing vessels, and it is asserted that as the use of the telephone does not require any special skill, this will render unnecessary the carrying of a wireless operator. N2w YORK taxis of the most modern class are now being equipped with a radio-receiver which is capable of receiving any programme within a radius of a hundred miles to the enclosed passenger compartment. The set is all-electric and operates on the battery of the car, which has been enlarged to "feed" the set as well. Radio is proving the rage in Russia. The Soviet is offering every encouragement by reduced fees and by the donation of free sets. In a little over a year the Soviet Government placed orders with the General Eleetrie Company of New York for £120,000 worth of radio supplies.
