ROUGH ON LIGHTS

DIFFICULTY AT 496. Persons who have cause to visit 4QG, Brisbane, notice that quite often one or more of the lights in the stuilios, reception hall or station are not alight. Althongh this might at first appear to be the result of carelessness | on the part of those responsible m not replacing burnt-out lamps, the trouble is not this at all. As a matter of fact, special care 1s taken in this respect, and almost every day a new light goes on somewhere. The trouble is that the dissipated energy fronx the 5000 watt transmitter is so great that the lamps all glow to a certain degree irrespective of whether they are switched on or not, the consequence being that when the power is supplied to them in the usual way, more energy is passing through the filament than they are designed for. The lamps do not, thereforr, stand up for any length of time under the overload. --
