RADIO NOTES

MISCELLANEOUS. (By “Transformer.”) A piece appeared lately in a radio journal stating that a listener, although he had written to several small New Zealand stations for their, cards, had not even received an answer; whereas, it was added, the Australian stations forwarded vertification cards by return mail'. “Transformer” has had instances of this happening. On ono occasion - no less than live letters were written to a minor station at Dunedin, but not a single reply has been ..received. Tho ever popular “Radio Scamps” will appear at IYA on Saturday evening in a novelty entertainment entitled “Nautical but Nice.” From the titlo it will bo seen that this programme which by tho way will bo interspaced with items by the IYA Orchestra Octet, will savour of the sea. Dance music will follow until 11 p.m. The programme at 2YA will also be ofa light nature, the contributing artists being the Mclodie Four, Madame Cora Gregg-Edmundson, of Wanganui, and Mr Will Bishop, the popular entertainer at •the piano. The instrumental music will be provided by the 2YA Salon Orchestra. A vaudeville and dance programme has been arranged for 3YA and will be relayed to 4YA. Mr Leslio Fleming will sing throe popular numbers —“Gipsy John,” “Rolling Down to Rio,” and “Old Farmer, John.” The Chatterboxes will present two twenty minutes entertainments of mirthful 6ongs and sketches. A bright instrumental programme will be given by. the Studio Octet under Mr Harold Beck. The church services to bo broadcast from 2YA on Sunday night will be the Easter service from the Vivian Street Church of Christ, tho preacher being Rev. 11. A. Clark, M.A., B.D. ELECTRICAL INTERFERENCE AND ITS CONNECTION WITH RADIO. (Continued from last woek). To prevent tho radio frequency current produced by a spark from getting on to tho lines connecting the sparking apparatus, some form ot filter circuit is necessary. A condenser (1 microfarad, more or less) connected across the sparking points will short circuit a considerable amount of the radio frequency current, or a condenser connected trom each side of the line to the ground will serve the same purpose as a choke coil in each side. VVhen any connections are made to the power lines, in order to avoid fire and peisonal injury, only apparatus which has been fully tested should be used. Faulty switches, etc., have been iound to cause almost unbelievable interference. A high inductance choke coil or high resistance connected to tho ground forms a simple filter circuit which should- prevent frequencies in the broadcast range From getting on the line. A choke coil in each sido of the line changes the characteristics of the circuit so as to reduce tho amount of power radiated. If such a filter circuit -is not effective, or is impracticable, the apparatus may in some cases be surrounded by a -solid, metal or wire screen which is thoroughly grounded. The screen should completely surround the apparatus. This may bo difficult. For oxample, in shielding the ignition system of a gasolene engine, the spark coils and all wires and other parts of the system must be enclosed in metal shields and these must be very well grounded. LOCATION OF SOURCE OF INTERFERENCE. The first thing to do in tracing the source ot trouble is to make sure it is not in the receiving set itself. Disconnect aorial and earth leuds to the set and short them. If the machine is silent then tho disturbance is created apart from* the set; if not, however, the machino is at fault. The next thing to do is to shut down the meter at the switchboard. Of course, if the set is A.C. operated this procedure would not bo done as all the house current would be turned off. If, however/* it is found that the interfence is caused somewhere in the house circuit the power board should be notified. Many of the companies have apparatus for the purpose of following up complaints of this kind. Usually, a receiving set with a coil antenm}., or loop antenna is used to determine the direction from which the intcrfoiing noiso comes and this outfit, usually a portable wireless receiver, is taken from place to piace until (he source of the- disturbance is found.- Tlie location ot such interference is often exteremely difficult to find and is a very baffling undertaking. It sometimes requires that tho power be shut off parts of the lino, in order to trace down the part of the line where the trouble arises. The trouble sometimes conies from a spark discharge from a leaky insulator to the ground, to the branch of a tree, or sometimes to the pole itself. Such a spark discharge is a loss to tho power company and thus when found benefits both parties, the power board and the listener. Large leaks and sparks may be more readily noticed at night, especially in wot weather. However, sparks which are too small to be noticed can interfere with radio reception quite severely. Commutators.—Where D.C. motors are in operation near a receiving set, interference is sometimes caused, especially when tho brushes on tho motor are sparking badly. The sparking should bo reduced ns much as possible by cleaning the commutator and properly setting the brushes. The remaining interference is sometimes overcome by placing two condensers (about 2 micro-farads) in series across the power supply line and connecting their mid-point to a good ground system. There are many other causes of interference too numerous to mention, but the majority, of interferences can generally be traced to electrical machinery. The electrical milking machino on the farm is very often illustrative of this. TO-NIGHT’S PROGRAMMES.
