  • Anotaciones
  • The Standard Radio & Electric Company Giblin Radioear Crystal Receiver was available in at least three different versions of this set and possibly four (Sievers mentions in Crystal Clear a model in the smaller box without the test buzzer). The first version came in a smaller box than the later two versions. This model pictured is a later version of the larger box model. In addition to the room for headphones and coils this model has a new buzzer arrangement with an ivory push button for buzzer operation. The tuning variable condenser was also different as was the chassis wiring.

    A Giblin-Remler Type 35 Honeycomb coil was supplied with the set for the reception of amateur signals. Other coils could be purchased to increase the wavelength range. For commercial and radio-phone signals in the 300 to 1,200 meter range a Type 100 Honeycomb coil was required. To receive time signals from Arlington on 2,500 meters a Type 300 coil was needed.

    Note: Sievers has a typo in the caption to Fig.56 (Vol.1, p.63): "Radiocar" instead of "Radioear".
