106 Receiver 3rd verion WWI production

• alternative name: American Marconi || Marconi, American
• Brand: Marconiphone

The third design change for the 106 came as a result of WWI. The dials and legends had been engraved into the front panel on previos models of the 106 up until WWI. However during the war the engraving machines were busy on war contracts for the military so Marconi started used etched metal dial legends to replace the engraving. The metal plates came in two versions one with a brass apperance and one with a black and white appearance. 

Production of the Marconi 106 continued at the Marconi Aldene plant in New Jersey until late 1919 when Marconi was absorbed into RCA. The 106 was equipped with two types of crystal detectors. A cerusite crystal and a carborundum. The cerusite was somewhat more sensitive but the carborundum was more stable in shipboard applications. The appropriate detector material for existing conditions was then placed in the single detector crystal holder mounted on the front panel of the receiver.

All 106 receivers covered the 200-3500 meter wave lengths and were used primarily for marine applications.
