It gives louder signals on CYV and phone transmission than by using the regular antenna and coupler. In the illustration C is a variable condenser of .001 mfd. and C2 is a .0005 variable condenser. A fixed grid condenser can be used, but a variable one is much better. The coil L is about 54 turns of Number 22 wire, tapped in nine places, or everv six turns. The tuning is done with the switch and C, while C2 controls the oscillations. If an amplifier is connected, it is applied as usual, that is, the primary of the transformer in the place of the phones. — Elwyn C.

Run your wiring as short as possible— never mind how it looks. This animal you are building is for listening, not looking, and it's worth two tricks if you use a panel mount socket so your variablo grid leak can be close at hand and close to the socket also. Operation of Wizard In operating, turn on filament rheostat just to the ragged edge of the hiss point, then throw the dial out the window — well, all right, keep it if you will promise not to go beyond that very slight hiss point. Never mind whether you think the condenser across the rotor is working or not. May be I know or I wouldn't use it, and no — it doesn't tune your plate. Use an open work closely coupled variometer; yes, about 60 turns on both rotor and stator; get a soldering iron that works and sweat the joints. If you don't know how to sweat a joint when soldering, then have nerve enough to ask a tinsmith. He knows. That's about all, except if you use dry cell tubes the potentiometer should have at least 1,600 ohms resistance, and your plate B voltage as marked on the tube carton. If storage 6-volt battery, then a potentiometer of around 200 ohms will do. Let's eat. (TO EE CONTINUED.) Ground Connections What is the best ground connection? Using tubes, the ground is perhaps more important than the aerial. Many sets will operate on ground alone. Custom has seemed to center on the water pipe as the best ground, although this is not always true. It ought to be the cold water pipe, and there must be a ground clamp, with the wire soldered to clamp. The larger the ground wire the better. Copper braid or ribbon is better than wire. The ground wire should be supported on insu This RADIO BOOR ' wUteave you money/ Compilei hy HARRY F. DART, B. S.E.I. Formerly with the Western Electric Co., and U. S.

"Freshman Selective" Mercury Variable Condenser It has been conceded by the Foremost Radio Engineers that a Variable Condenser with Mercury plates is the most efficient for fine adjustment and selective tuning. Our engineers, after exhaustive experiments and research work, have developed a Variable Condenser with Mercury plates separated by heavy Mica dielectric. It is the ONLY VARIABLE CONDENSER the plates of which actually vary in area —AN ENGINEERING FEAT NE\"ER ACCOMPLISHED BEFORE.
