In the first instance, an outside source is used to excite the circuit in the same way that a small D. C. gen- erator or battery is used to excite Y field of a large alternator, while in the second case no outside source is used to produce the initial impulse | which sets the circuit into oscillation. A very slight disturbance of the electrical balance of the circuit, such, for instance, as turning on the fila- | ment current or connecting in the plate battery, is sufficient to produce the initial flare to set the circuit into operation. Bach additional amplified impuise fed back into the grid circuit tends to increase the disturbing element and | to build up the oscillation strength to | | higher and higher values, within the limits imposed by the flattening ends of the characteristic curve of the tube. very i Fig2 the plate coil, while No. 3 .marks the beginning and No. 4 the end of the grid chil. You will notice that in this case the adjacent ends of the coils are connected with the grid and plate respectively. It is also possible to get the same effect by reversing the connections to both colls, that is by connecting the plate with No. 1 and the grid with No. 4, while the positive B battery is conected with. The “Vicious Cirele.,” The action which takes place might be termed a ““vicious circle” of the endless chain type.

This will be the second address of | ort, as Gen. Pershing. who soon retir is the only ranking Army officer to wear the mantle of general es, laid down by Washing- ton at Rocky Point. near Princeton, V. . in 1783, W hington's address reached the ears of only a few officers and troops, whereas the remarks co- incident with the retirement of our ond general of the Armies will | reach millions, due to the present de- velopment of radio broadcasting aid- ed by telephony. | Facilities combining radio and telephon will make it possible for every member of the Regular Army, and probably all National Guard forc to hear the words of their chief, not counting reserve officers and men and countless patriotic cit- zens who choose to listen in. If the Army radio net, which reaches every post and station, is hooked in with the Bell stem of wires and broadcasters, pr: ically every soldier on duty will have an opportunity to| receive Gen. Pershing's message. Reassuring to the People. The use of radio in connection with national defense is not surprising, but it reassuring to realize that the manpower of the country can be called to service by means of a single broadcast, literally springing to arms in a single night. A few years ago this would not have been possible When it is considered that the woice of the commander-in-chief, his every word and accent, may be projected into space covering the whole country from coast to coast, the real value of radio broadcasting as an asset in_defensive mobilization is realized. Never before has a defense test of the organized military forces of the country been attempted and never before was a single broadcast planned of so far-reaching a character. Thir- teen stations carried the voices from the political conventions and later the utterances of the two candidates, as far West as Kansas City, but it possible for the telephone company to link_many more stations, including far Western and even Cuban broad- caster: In terms of national mobili- zation, this assures the messages reaching every city, village and even the farms. Useful to the Regulars. Those in the regular service know where to report locally if not as- sembled, and Reserve officers on Sep- | tember 12, know how to proceed with the recruiting of their units, report- ing to their superior officers in the nine corps areas. The real purpose of this test, according to Gen. Per- shing, is not to assemble or recruit an army, but solely “a demonstration to the American people that it is neces- sary to have some preliminary organ- ization in order to avoid the danger of delay if war comes.” For this reason he will speak to the soldiers and patriots of the country on Sep- tember 12, on the anniversary of the victory of the American arms at St. Mihiel.

The musicians are ali native Hawaiians. when the circuit is to be used as a regenerative detector circuit. Setting the Cofls. When a 180 degree coupler is used, set the two coils concentrically and connect the beginning and end of the windings as shown in Figure 2. It the polarity of the coils is re- versed by reversing the connections on one of the coils, the effect is to weaken or reduce the tendency of the circuit to oscillate unless the con- stants of the grid and plate circuits are such that the plate circuit is prac- tically in resonance with the grid cir- cuit when regeneration would take place in spite of the wrong polarity through the tuned-plate circuit method. The method of regeneration in which a coil connected into the plgte cir- cuit is placed in inductive Relation with the grid coll is called the “tick- ler coil inductive feedback” method of regeneration. Regeneration and the generation of oscillations can also be accomplished by the “tuned-plate” method in which the plate circuit of the tube is tuned into Tesonance with the grid circuit with feed- back of energy taking place through the capacity coupling of the grid-to- plate capacity of the tube. There are other methods, but these two are the most commonly used and most practical methods. So far we have dwelt on the effects produced by the regenerative action which being fed back into the grid circuit reinforces the disturbance in the grid circuit, thereby creating a greater disturbance in the plate cir- No. 2 and the positive A battery with No. 3. These are the connectlons which should be used when the cir- cuit 1s to be used as an oscillator or in these circuits. Tomorrow we will take up the desirable and undesirable clements introduced through this ac- tion. of | D. C, WEDNESDAY, AUGUST 20, 1924. “MID-NITE” MARDI GRAS. [New Radio Feature August 25 by WLS.
