100 RADIO HOOK-UPSFig. 13Fig. 12. A one control circuit employing a variometer willgive good results.Fig. 13. A fairly selective circuit employing a tapped coilmay be connected as shown.rlmegohm".00015.00/lmegohm.00/ r "'00015in#vé'12fvarig. 14 Fig. 15Fig. 14. Much greater selectivity may be obtained with anaudion detector by employing a loose coupler.Fig. 15. Two Honeycomb coils make a very good tuner inwhich the tuning is accomplished by means of variable condensers.I megohm Double cirrriifOpen circuit,Ark ; A. if Trans( jacir0 ~o.000151011111022t v. á + 11191111111 422 veFig. 16Fig. 16.
