100 RADIO HOOK-UPSLITfngsyn7avrsAirAilJFig. 611Fig. 55. Here is a very good combination. A detector, onestage of transformer radio frequency amplification and two stagesof audio frequency amplification. The radio frequency increasesthe range of the receiver while the audio frequency provides thevolume.titlit Y1 M?tmIt I'¡It=111+rh1 /f M W [ Y'Fig. 56. A receiver with the addition of two stages of radiofrequency and two stages of audio frequency amplification. Thisarrangement is sensitive enough to be used with a loop aerial,although better resulta will be had by using It with an outsideaerial as shown.80
100 RADIO HOOK-UPSR.f7.R.fxPv/rn/iAorr/uPls. 5745-!B K B +Fig. 57. A two circuit receiver with three stages of radiofrequency amplification. Such an arrangement is very sensitiveindeed, and will pick up the long distance stations. Three standardradio frequency transformers are used as ah'wn.Fls. 60Fig. 58. Here is a switching arrangement for cutting in orout the successive stages of radio frequency amplification whichis often desirable. By placing S-3 on 1 only the detector is In use.By placing S-3 on 2 and S-2 up, the detector and one stage are inuse. With S-3 on 2, S-2 down, and S-1 closed the detect= andtwo stages are brought into operation.31
