RADIO CRACKLES. TRACING RECEIVER NOISES. j The cause of crackling sounds in a I newly-built receiver is often found difficult lo trace (writes “Spark Gap" in llie July Australian Journal). Perhaps ail is going well when a mysterious spluttering noise breaks in upon I lie reception and spoils it entirely, if Ihe aerial be removed from I he lerininnl screw and Ihe noise still eonlinuos it may safely- be said that static is not responsible for the trouble. 1L is, therefore, in the re-

ceiver and must lpe located and removed.

The' only way of discovering tlic cause of this interruption is to go over every part of the receiver with the utmost care until the fault is traced. The earth wiring, grid leak, condensers and loud speaker must, all he examined. If it is a battery set the batteries must be tested. If an allelectric receiver, be sure that the current is switched oft and I lie plug removed from tlm socket before touching any exposed wires. First disconnect the earth wire. Next, look at the wiring to see if any of the leads arc touching, in order to make sure that tills I rouble will not occur in future separate each wire from ils neighbour by fully half an Inch. „ , Grid leaks are often the cause o> spluttering , ■sounds. Test by shortcircuiting; if the grid leak is at faul the noises will cease immediately. Examine every connection by tapping the panel sharply with a thin piece of wood. If the noises Increase or disappear lor a moment tighten every nut and see that all joints are properly soldered. If the crackling noises become worse as the condenser dial is slowly turned the vanes arc probably touching; these must he separted with great care, for the adjustment of a variable condenser is rather a delicate mailer. All dust between liie vanes should lie removed. The only thing left- that might cause the trouble is the speaker leads. Constant use may have, worn away Ihe insula lion between the twin wires, so that every lime Ihe leads are shifted a partial sliort-rirruit Lakes place. Perhaps one of I lie leads is broken, and the brushing contact of the ends produced the crackling. 11 is also possible that 1 lie insulation of the windings has been destroyed by an overload of current.
