The discovery is due to the enterprise of two German scientists, but its exploitation and the development of its possibilities were quickly seized upon by William Dubilier, the well-known Radio manufacturer. The machine consists of a typewriter, a registering apparatus, and an assembly of eight compartments, each containing what looks like a transformer built on top of a magneto. At the head of each compartment are movable rods which send out the message by means of musical notes. Uses Interchangeable Code The receiving apparatus looks even simpler—a four-tube set, a box full of plugs and wires, and a camera-like mechanism, with a motor attachment; be- sides this, the wheel around which the tape runs. Secrecy is obtained by means of the fact that countless combinations can be used at will.

Although long time, made with end plates of hard naturally a single layer of insulated wire (Continued on page 20) the term was not used in connection with them, the various types of inductance such as honeycomb coils and spider web coils, were the result of an effort to elimi- nate loss in the inductance. Constructing fixed condensers with mica as the dielec- tric instead of paper and similar sub- stances, was a step in the direction of reducing losses in fixed condensers. The chief advantage of low losses is, as was mentioned, in increased selectivity, as the increased range obtained is not very marked. When we say that a receiving set tunes very sharply, we mean that it has excellent selectivity and a little study of the matter will show that reducing the The JEWELL losses in a circuit which carries current at Radio frequency gives us sharp tuning.

November 15, 1924 RADIO DIGES T—Illustrated 21 How to Build the Simplest Possible Super-Het Part I — Parts Essential for Building Set By John G. Ryan THERE have been many articles pub- lished in Radio Digest and other Radio magazines, on super-hetero- dynes—long sets, short ones, high panels, deep baseboards, many controls, two con- trols, one stage of audio, two stages and push pull, preceded by straight R. P., and even reflexed. Fans have built them, some with success and some with nothing to show except a lot of parts and a feel- ing of disgust. The general reaction has been a demand for something simpler for a set that the average man, not an engineer or even an advanced experi- menter, could construct and operate suc- cessfully. To which, one might well reply, "Well, don't build a super. Con- struct something with less tubes and less necessity for accuracy."

i November 15, 1924 RADIO DIGES T—Illustrated 27 Secrets of Selectivity and Regeneration Part V—Conclusion; General Principles to Remember By William W. Harper

THE articles which have preceded INan attempt was made to present the influence of the more important fac- tors such as high frequency resistance and extraneous coupling, upon the re- generation and selectivity. In all cases the data given was based upon one stage of regenerative Radio frequency ampli- fication. The more elaborate arrange- ments may also be subjected to similar analysis and the same principles can be applied. The second article disclosed a method of improving both selectivity and response by the use of more than one sharply tuned circuit. A receiving system con- sisting of one regenerative amplifier with two tuning circuits was described. It is well known that the degree of selectivity QS>^ further increased by the utiliza- can be Figure 12 tion of more tuning circuits.

These tubes are manufactured by the Goode Tube Corporation of Owensboro.

Ky. # and our tests and experiments with them show them to be extraordi- narily fine for amplification. The filament is rated at five volts to operate on the standard six-volt bat- tery. The current consumption is .2S ElSEMANN amperes and the plate voltage recom- mended Is from 20 to 120. In the tests we loaded these tubes with 230 volts on the plate with no indication of choking. By rheostat action, the burn-out point of the filament was measured on one tube. Nineteen volts were applied before' the filament snapped. This is an indication of long tube life. The Goode tube is constructed with a standard base to fit the standard sockets. As a detector the operation is smooth, the tube working best with a grid leak of from two to five meg-- ohms. A higher resistance gives better results on weak signals, but makes the operation slightly more critical. Negative grid biasing with this tube as with all others, gives more satis- factory results. For a plate voltage of 60, the nega- tive bias from the "C" battery should he from 1.5 to 3 volts. For 120 volts on the plate the negative bias should he from 6 to 9 volts.
