BY EDGAR H. FELIX. Have you ever heard clearly over Your radiophone one day and been utterly disgusted with resuits the next? If you have had this experi- once the chances are that your ad- justments were’ faulty. The tuming of a radlo recelver is simple enough if the functioning or the few simple controls are known to the operator. The usual regenerative vacuum tube receiver has the follow- ing controls, as shown in the accom- panying diagram: A—Coupling. B—Regeneration. C—Tunning (antenna wave and secondary wave length). D—Filament rheostats. In some sets controls A and C are combined in a single control which adjusts the wave length of both pri- amary and secondary circuit. Some of the sets of the more inexpensive types are designed without a secondary cir- e | length cuit, with the consequent sacrifice of selectivity. In all cases, however, the process of adjustment is some- what similar. Three adjustments are made before the operator attempts to recelve any particular station. First, the aerial switch is placed in receiv- ing position. Second, the fllaments of the tube or tubes are lighted by means of special switches employed for the purpose or by the automatic jack which completes the filament circuits when the plug connected with the tolephone receivers is inserted in the Third, the adjustment of the This is gradually BY RADIO TODAY Complete Programs of Radio Broadcasting Stations.

The resis ance is then turned back slightly un- til that nolse just inaudible. Now the operator ready to tune his ‘The cont: Kknob, marked “regene! tion” or “tickler,” is placed at mini- mum. g The first step in tuning for a par- ticular station is to just for wave length. In most of the recelvers that are being 8old for broadeasting there Is but one adjustment for this pur- pose. With such sets it fs merely necessary to turn slowly from mini- mum to maximum, stopping at any point where a desired station 18 heard. If the operator has no knowl- edge whatever of the approximate ad- justments for any particular wave length, he adjusts the primary circuit to one-third or one-half its maximum value. If the coupling between the primary and secondary circuits is ad- justable, it is placed at maximum dur- circuit is made in the same manner as first described for primary adjust- ment of the single control recelver. When the desired signal is properly tuned in on the secondary, a readjusi- ment of the primary circuit is made until the signal is heard with maxi- mum loudness. Once the correct adjustment for wave length has been made, it is a simple matter to adjust the “regen- eration,” “tickler” or “feed-back' con- trol. This is done by slowly turning the control knob from the minimum position toward the maximum. At first this action may not produce any perceptible result, then there will be a sudden and surprising increase % signal strength. If you increase regencration too much, however, the quality of the re- ceived signals becomes distorted. At first only the high notes are affected, but if the adjustment is turned still further to maximum the music be- comes completely distorted and its tonal qualities destroyed.

A good many of the horns are of tin or other sheet metal, which often produce resonance effects and blaring scunds on some tones.

Distortion of the sound waves in & lcud speaker is to be shunned, and vet considerable volume is desirable in most cases. The loud speaker in the cut will not distort The horn is mental mubic come through clearly audible and natural. When two stage audio-frequency amplifiers are used it is customary to use from forty to ninety volts in many loud speakers | higher voltages cannot be used with- | out danger of damage to the tele-| phone receiver or other reproducing device used. And yet if considerable sound volume is required it is usu- ally necessary to use even higher voltages in order to secure greater power with which to operate the loud speaker to best advantage With the lound speaker (illustrated) as high as 350 wolts may be used without fear of damage. Power tubes may thus be used and make ex- cellent amplifiers for use in connec- tion with loud speaking devices which can be used in connection.
