The Weagant undamped wave receiver.
From the book 'Vacuum Tubes in Wireless Communication' by Elmer E. Bucher. Published in 1919.
Regenerative coupling such as previously shown are not essential to the production of beat currents in the reception of continuous waves
.
This system, devised by Mr. Roy A. Weagant, functions satisfactorily with the simple set of connections shown. The principle feature of this system is the "X", or tertiary circuit, consisting of the condenser C-3 and the inductance L-3, which are connected in series, and in shunt to the plate circuit. By careful adjusting the capacity of the condensers in the secondary and "X" circuits, or change both the inductance and capacity, the system will oscillate at radio frequency which may be made to differ slightly from the frequency of the incoming signals. Beats of any desired frequency are thus formed
.
Modified Weagant receiver. It is simply an extension of the "X" circuit, regenerative coupling being secured through the coupling L-4, L-5.
