[Boatanchors] My unknown 1920s receiver

[Glen Zook]

It is the r.f. bypass for the tickler coil.  What is unusual is the use of the tickler coil for the antenna input coil or the use of the antenna input coil for a tickler coil.  Since the antenna input coil and the tuned circuit coil are contained within the same commercially produced unit, the brown section is the input coil and the larger green section the tuned circuit coil, it really is a case of using the antenna input coil for the tickler coil.



Every regenerative circuit that I have seen (of course I have not seen them all) there are 3-coils, not 2, with the tickler coil being separate from the antenna input coil.

    I don't get the fixed capacitor from the Antenna connection to the tube cathode.
