A t certain points of the variometer · dial you should be able to tuao '· fhe condeasc-r ".vithoiit hearing j whistles. In other ivords. the cir- · cuit should be operated in a state where you can make the oscillate by increasing the vario-; meter sadactaace. but keep the j tube from oscillating on the rest i of the dial. ! Tune roughly for a station by j means of the taps on the coil," raoving the condenser dial sloivly over the scale for each tap. Vvhea you hear a station, bring it in as loud as possible by means of j condenser dial and then rotate the ' plate variometer dial until the i jj: I volume is satisfactory or just be- j fore the point where the tube -will spill over into oscillation. It may; now be necessary to go back and , j change the setting ot the condenser condenser slightly to make up for the detuning effect of the vario- meter. It will not be necessary to use a vernier rheostat nor -will it be necessary to use the rheostat for ! tuning. Leave the rheostat in · position and vary the variometer ] dial. If you are accustomed to! s I operating an TJltTa-Audion circuit i i it may take a little time to j accustomed to 'this, but after you | learn the proper way to handle | variometer control of regeneration, ! you ·«·:!! surely prefer it to the; ! old method. ] (Copyright. 1924, by the S. :N, L. i Technical Syndicate) . . i According to health experts!
