Radioear Crystal Receiver Large box with buzzer early

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. In this version the wooden case is large enough to house the headphones and spare honeycomb coils. The binding post legends are no longer stamped into the wood next to the post. The chassis was identical to the earlier small box set.

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.
