RADIO DIGEST — Illustrated October 6, 1923 AN ULTRA AUDION SIMPLEX DIAGRAM "A" BATTERY B" BATTERY THE circuit shown in the above diagram is by no means a new one but it has numerous good points that make it especially attractive for the new fan. Not only is it an extremely efficient form of circuit, but its simplicity and low cost make it an ideal receiver. A I apparatus required is one tube socket, one rheostat, one variable condenser (.001 mfd.) preferably with vernier, a variable grid leak and grid condenser (panel mount unit was used) on variometer, and eight binding posts. A dry cell tube can be used if desired; as a single wire not over 60 feet long is sufficient. If a longer aerial is used the condenser capacity may have to be reduced to .0005 microfarads. Get Advice Before Purchasing Anyone having little technical knowledge on the subject of radio should take some experienced friend's advice before buying any piece of apparatus.. If this is not possible, he should purchase articles made by companies having a recognized standing in the field and whose engineers are capable of giving the best in design.

CO. 1 1 2620 VICTOR ST., KANSAS CITY. MO. What About It? Isn't it about time to stop experimenting with multiple control circuits and build one that, combining ease of assembly and operation, loudness, clarity and selectivity of signals, as well as beautiful appearance, is excelled by none? THE ELGIN SUPER-REINARTZ RADIO RECEIVING SET Embodies all the advantages of the well known Elgin Reinartz (the set which was largely responsible for the popularity of this wonderful circuit) and many others. It is much louder, more selective, requires no storage battery, and can be used with excellent results on a short or loop aerial. It has brought in California stations two thousand miles from Elgin, clearly and without interference on a loud speaker with only one tube, and that while our powerful local station was broadcasting three miles away.

The the B battery is 22% volt recommended, but this can be increased if UV-99 or C-299 tubes are used. As the diagram indicates, the wiring: is very simple. The aerial need not be a very long one Lettering Bakelite Panel To letter a bakelite panel, clean the surface with wood alcohol to remove any greasy film, then write what you want on the panel with a sharp, stiff steel pen and draftsman's white ink, such as is used on blueprints. When the writing is perfectly dry, cover it with transparent varnish to protect it, using a fine, soft hair brush. If at any future time you want to remove it, dampen a rag with wood alcohol and wash it off; the wood alcohol dissolves the varnish. — James E. Murray, New York city. 2650 MILES with ONE TUBE.
