Notes

Short-Wave Regenerative Receiver Type CR-2. Wave-length range 170 to 580/600 meters.

The unit as such is not a complete Regenerative Receiver! To employ regeneration it requires a vacuum tube unit, e.g.Type RORH, this may be used to advantage with the CR-2, as their terminals correspond and permit the use of straight, short, bus connections.
