Some Excellent Receiver

QuR constructional article next- week should appeal to all constructora, We have been asked many times fag the 1931 Browning Drake and have consequently built a model incorporating ail the new ideas of design. This will be published next week under the name of "The Outspan Five." There are two stages of screen grid, differential condenser controlled reaction, and two audio stages. The present set used three dials because it. is not an easy matter to perfectly match three coils when regeneration is used. We are at present experimenting with the coils in order to get them perfecily matched, and when this is done we shall describe the set for single dial control. Instructions will be given for changing over the old Browning Drakes to this type of receiver, for it is quite possible to use the three-coil regenerator former of the B.D. Our next constructional feature wiil be the three-valve differential receiver. This is the next in the series being described by "Cathode." As before, ¥% will be followed by our own description of a complete three-valver, "The Kestrel Three." oe This receiver will be followed by a. complete four-valve differential. %éceiver. tt
