Show how to get away from reflex difficulties the chief lef many seem to have with the reflex circuit are lack of selectivity and trouble in getting the set to td oscil oscillate lafe properly y tho the source of much trouble can generally be attributed to poorly designed radio frequency amplifying transformers this type of transformer Is an important component in the success of it a reflex set quality and tita trade mark of a reliable manufacture should be tho the factors which govern the sa at letlon of an amplifying transformer it if the transformer to Is of tile open core type with tile the confer center opened a small iron or stoel steel rod placed through the center hole helps to broaden the tha wave length range of the tha transformer and permits better control of the oscillating cil cli point generally two or three one eighth inch rods about one inch long are sufficient clent reversing the primary and secondary leads of mhd radio frequency transformer often improves results resul tn all wires must le ile short especially those lending leading from tile the grids and plates platen ot of the tubes if I 1 audio transformers are used in the circuit connect the cores to the he ground bin binding ing post low ratto ratio audio transformers such as 4 or 8 to 1 crin cas generally bu bo depended in a reflex hookup hook up it alood a joop antenna Is employed and toaia too large afo ai 1 con condenser d ens er shunted across it bl or too muoi aae alre ts is used 1 la in the toon loop the tuning to Is ettely to be broad |
