The RA Regenerative tuner was designed by Frank Conrad, and a device of this kind employed at his experimental station 8XK near Pittsburgh. Unit is essentially a regenerative detector with two audio stages, either or both of which may be employed by use of the proper jack. The RC receiver utilizes a UV-200 detector and UV-201 amplifier tubes. A model CB loading coil, when put in series with the antenna, extends wavelength range to 1800-2800 meters.
