Someone is looking inyour window !

October 2 ;lights are going on an hour earlier, men are settling down by the fire and a hand in almost every home is switching on the wireless. Loud speakers are busy once more --and all the time current is being drained steadily out of the batteries, every hour sees all these people getting closer and closer to another battery purchase. Now: who is going to supply those batteries? We'll tell you.It is the man who puts the batteries in his window. When ,ou switch on your window lights as the men come back from business, let them see Britain's Best Battery reminding them of that battery soon to be needed at home. Why shouldn't they get it now, and save time and trouble ? And that is precisely what they will do, if they see the name Ever Ready, and a battery or two in your window.

L._ October 1, 1932 The Broadcaster and Wireless Retailer Id ERN o -T.D. COIL AN UP-TO-DATE COIL WITH UP-TO-DATE FEATURES TYPE T.D., an entirely new COLVERN COIL, designed to give super selectivity on both long and broadcast wave -bands. TYPE T.D. The coil is completely screened, giving a very neat appearance, and incorporates tapped aerial coupling and reaction, while the four alternative aerial tappings are arranged as sockets with a wander plug. PRICE The first two tappings give aerial couplings similar to those normally employed, but with greatly increased selectivity. 8/6 Nos. 4 and 5 give a high degree of selectivity with weak aerial coupling- suitable for use in a " swamp " area. A most important feature of this coil is that there is no break through on the long wave -band from B.B.C. stations. Specified for the " Apex," described in " Popular Wireless," 1st October, 1932.
