NOTES AND NEWS.

2BX- Eoei Wall. "Aerial’s ” old B.T. (made up from the kit five or six years ago) fas once again brought into commission atter a thorough overhaul and, coupled up to a Jensen moving-coil loud speaker (6v. D.C.), is giving its former good results. After listening to last night's fine openair band concert put on by 3YA. and the concluding part of 2YA's broadcast, turned on 2BL, Sydney. At first, volume was not so good, but after a few minutes —it takes that for the receiver to “ warm up,” as it were—2BL *• came through ” clearly and steadily. There was very little signs of interference and reception remained good right up to midnight. One very much appreciated advantage of a well-made moving-coil loud speaker is the effective damping, or smothering, of atmospheric or local electrical noises. The clarity of reception is not affected to any great extent and there's not the least doubt about the beauty of the tone obtained. i> By the way. the use of Philips valves for detector and the two audio stages with the moving-coil speaker calls for a somewhat critical adjustment of “ B '* voltage for the detector and also the amount of grid bias used. Too much grid bias on either the first or second audio causes a serious damping of signals while too little fails to give satisfactory tone. Another point that operators of battery sets should bear in mind is that the receiver must (“ must.” please) be turned off when adjustments to grid bias are being made. Failure to do this results in the valves being ” shocked ” temporarily, sometimes; permanently, perhaps. 2£ ♦** ♦'* Operators using ”B ” eliminators should invest in a well-made and thoroughly reliable voltmeter —one reading to 200 volts for preference—ln order to i test the voltage to R.F., detector and ! A.F. Don’t be tempted to buy a. cheap instrument—cheap ones are usually nasty ones and it is important that you ! should be able to depend on the readings ! given. Check the voltages frequently I and do it by means of extension handles to the meter’s tags applied across the battery terminals on the set. S.W. Report. "Insulator’s” usual weekly report on i eception of short wave broadcasts during the past week will appear m tomorrow's “ Star.” An* Appreciation. Air J. H. Andrews, G 4 2.
