The source of high potential is celve broadoasting by making use of | COnnected across terminals A and B. the ordinary “bell” circuit fn the housé. In every apartment house there is usually a front-door bel and aleo a buzzer in the Kitchen, which is cannected for use in the dumb waiter. This latter circuit makes a good an- tenna’because it {s not used as much as the front-door bell. Buss (0 Be Avolded. As & slight buzz will be heard in the receiver every time the button is pushed, and as the door bell ls apt to be rung at almost any time, the dumb- waliter buzzer s thé more serviceable of the two. ¥ Using one side of this circult will not harm either the bell circuit or your receiver. Even when the buszer or bell is rung, it will have no effect on the set, except that a noise will be heard. To connect the radio receiver to such an antenna fs simple. Loosen up one of the binding posts on the busser or bell and connect a wire to it. The other end of this wire should be run down to the antenna binding post on the'radio set. In cohnecting this wire to the buzser, be sure that the wire which ‘wae already oh .the binding post of the buzzer is put back in place, otherwise the buzzer will mot ring. Surprising Results Possible. Of course, it fs not possible to re- ceive much DX on an antenna of this sort, but if circumstances are right, some surprising results may be had. On local broadcasting stations the signals should be almost as loud as with the outdoor antenna. In some of the large apartment houses, wheére the bell wiring s run all through the bullding, the wave length may be a little too high for broadcasting reception; for this rea- son it will ba well to insert a 43-plate varfable condenser in the ground lead This will reduce the wave length and glve better results.

The amplitude of the oseiltutions and the periods can be controlled by properly spacing the’ distance be- tween ‘the electrodes of the spark gap.

Damped Oacillations. The osciliations produced in the oscillatory circuit are known as damped oscillations because the am- plitude of the oscillation decreases. This type of oscillation can be used to advantage in radio telegra- phy, but its use s impossible In radio telephony, because the damping of the osctliations makes the use of such osclllations impossible as producers of the stesdy amplitude, continuous waves required as carrier waves in radio telephony It was not until about 15 years ago that a special alternator capable of producing high frequency oscilla- tions suitable for radlio telephony was perfected by Ernst I.
