“ ARTIFICIAL ” FADING IN S.W. RECEPTION. Its Cause and Cure. A trouble which is sometimes met with in short-wave sets of the homebuilt variety is an unsteadiness or “wobbling” of the signals received. This complaint is easily recognisable, as, when a telephony transmission is tuned in, the signals fade rapidly in and out, the “out” periods generally being accompanied by distortion or even actual “howling.” In the case of continu-ous-wave Morse transmissions, the note, instead of remaining steady, keeps risir g and falling in pitch, these variations being accompanied by slight fluctuations in signal strength. This “artificial fading” should not be confused with the natural high-speed fading often experienced in the reception of distant short-wave transmissions. In the case of natural fading, the fluctuations vary with different stations, and on some transmissions are not experienced at all, whereas the “wobbling” effect with which we are dealing is equally noticeable on all signals of approximately similar strength. The trouble is caused by very small mechanical movements of the metal parts constituting the tuned circuit giving rise to variations of frequency which, although very minute, are sufficient to upset the extremely sharp and critical adjustment of the tuning. One source of this trouble is a slack and swaying aerial, which is well known to cause artificial fading effects, even on the ordinary broadcast wavelengths, when distant stations are being received, but, on the high frequencies (short waves), the effect is very much more pronounced. Another less cbvious cause of these fluctuations in tuning is located in the coils. The necessary “low-loss” qualifications in short-wave coils are generally attained by cutting down to a minimum the amount of solid dielectric material within the magnetic field of the coil. If this process is carried too far, the windings are not adequately supported, and tend to quiver whenever the slightest mechanical vibration reaches them. The slight movements of adjacent turns in relation to one another upset the tuning, and, by producing the effect already described, may completely spoil reception. When winding home-made short-wave coils, therefore, it is most important to make sure that the windings are rigidly supported, even if this entails a slight sacrifice in thte electrical efficiency of the coil.
