NOTES Static was pronounced last evening and reception was consequently not up to the usual standard. A very fine concert was transmitted by 2BL, Sydney, but the interference of static spoilt good reception. SPEED OF RADIO WAVES Radio waves travel through the ether at the speed of light, or 156.000 miles a second. At this tremendous speed the reception of a signal over the normal broadcast range is instantaneous and takes place within the fractional part of a second. AUSTRALIA’S RECEIVING SETS Australia now has 154,740 licensed receiving sets. CRYSTAL RECEIVERS A crystal receiver will give very clear reception at good phone strength up to a distance of from 20 or 36 miles from a high-powered broadcasting station. It will, of course, receive broadcasts over a greater distance, but not with the same good strength. It has three main disadvantages over a valve receiver—it will not operate a loud speaker; it is fairly difficult to tune out undesired stations, and often requires frequent adjustment. One advantage is that it is the simplest receiver known, is easy to construct, and the upkeep is almost nil. In order to obtain the maximum signal strength from this receiver great care must be given to the aerial system. The aerial should not be too high, as a considerable amount of interference will be encountered, but on the other hand a low one is not efficient. An aerial of about 30 t 0 35 feet in height, and SO to 100 feet in length (including down lead) of rigid construction, and well insulated and free from contact with surrounding obstacles (at least two feet clear of walls, etc.) will be found to give quite good results. The crystal itself is the most important part of a receiver. They may be divided into two classes—the class that requires a metal contact and the “perikon.” requiring a second crystal to make contact with them. These are not very popular with the average listener. A crystal must never be handled with the fingers, or it will quickly become insensitive on account of a thin film of oil from the pores of the skin. It may be cleansed by immersion for about ten minutes in alcohol, allowing it to dry Headphones used with these receivers must be of high resistance, 3,000 to 4,000 ohms. U.S.A. BROADCAST 3 r ATIONS.
