notes: label: Description (Brief)
content: The donor reported: "This wireless tuning coil was made and used in 1907. The Electro Importing Company sliders were added later --the ball-bearing red and black block-like pieces of hard rubber. Before these were added pieces of bent spring bronze were used to make the connections. This wireless tuning receiver had the advantage of an antenna nearly 200 feet high---atop the flag mast which was atop the cupola on top of a school. Reception was exceptional most of the time. A range of 1700 miles was frequently covered with good copy---mostly from ships at sea. The Station was located at Pennington, New Jersey. The detector was a choice between electrolytic or galena---the galena usually more dependable. The station was written up in a Trenton daily paper along about 1910 or 1911. [Prior to donation] I varnished the wire because the wire was loose and might have come off. The new clean piece of paper at the end was put on at the same time. It covers an unwound potion of the drum, the original looked too soiled, etc."
