    The receiver circuit used by Godley in the succesful transatlantic test of December 1921. With a regenerative first detector and a regenerative i.f. amplifier, this could been the first amateur receiver to approach single-signal c.w. performance.The detector tubes were UV-200s, the others, A-P amplifiers of the "hard" variety.

    This is the original legend of the schematic.

    From an article by Sergio Pandolfi on "Radio Rivista" official organ of "ARI Amateur. Radio Association." of Italy, April 1976.

    This receiver was built for the transatlantic tests done in November 1921. The receiver was used to listen to the time signals.
