Phonographs
Floor model and tabletop phonographs were equally popular. Floor models had space in the cabinet for storing cylinders or discs. | ----- |

cylinder phonographs Cylinder phonographs came in both floor model and tabletop styles. Concert phonographs played the extra-wide concert cylinders, which were being phased out in 1912. All other phonographs played standard-sized cylinders. The stylus assembly was known as the reproducer. For standard cylinders, the length of the recording (two or four minutes) determined the type of reproducer needed. A few models came with interchangeable reproducers. You could purchase an upgrade kit to play the newer four-minute records on older two-minute machines. When Edison's Blue Amberol cylinders were introduced in 1912, they used a diamond reproducer for optimum sound quality. Later Amberola models came equipped with a diamond reproducer, and upgrade kits were available for other four-minute phonographs. | Edison Amberola tabletop model tabletop with external horn Edison Columbia Graphophone Edison Concert (concert-sized cylinders) U-S Phonograph Company Sears Oxford tabletop with enclosed horn Edison Amberola Edison Diamond Amberola floor model with enclosed horn Edison Amberola Edison Diamond Amberola | |||

disc phonographs The Victor Victrola was available in both floor model and tabletop styles. Because it was the most popular enclosed-horn phonograph, the terms victrola and vic were used to refer to any floor model phonograph with an enclosed horn, whether it was made by Victor or not. Tabletop models were known as gramophones, phonographs, talking machines and music machines. Depending on size and price, wind-up phonographs could usually play up to eight records with a single winding. To accomodate the varying disc speeds, the playback speed was adjustable. Box of 100 steel needles Standard phonographs used steel, bamboo or cactus-thorn needles. Steel needles had to be replaced after every two songs, while bamboo and thorn needles could be resharpened and used again. A few models used a diamond or sapphire stylus, and could only play records designed for them. There were all sorts of adaptors available, which made it possible for phonographs to play records that were not compatible. Some phonographs could be fitted with a swivel attachment that had all four needle types: steel, bamboo, diamond and sapphire.

Wireless | ----- | wireless buffs As early as 1905, amateur listeners could buy and assemble "wireless telegraph kits." In 1906, after it was discovered that radio waves could be detected by touching a mineral crystal with a wire, science magazines published instructions for building crystal sets. Listening was done with headphones, and the Morse code messages were hastily jotted down with paper and pencil. wireless on land In the 1910s, other industries discovered the usefulness of wireless. Hotels, department stores, railroads and shipping businesses all installed wireless equipment. Land stations provided farmers, newspapers and wireless buffs with weather reports, hog prices, headlines and baseball scores. In the 1910s, there were hundreds of commercial wireless stations and thousands of amateur stations in the United States. In 1910, there were already so many amateur stations that the issue of radio interference was becoming a real problem. There were no regulations to govern the number of stations, their wavelengths or the manufacture of selective tuning equipment. radio licensing The Radio Act Of 1912 was enacted by the Department of Commerce. This law required that all wireless stations be licensed. It developed eight licensing categories and devised a system of assigning call-letters. Land stations operating as a business received limited commercial licenses, while most other stations fell into the experimental or amateur categories. during & after the war When America entered World War I in 1917, the government suspended all amateur radio licenses and placed the commercial Marconi land stations under government control. On the battlefield, Morse code wireless was used for radio beacons and field communications. After the war, the wireless land stations were returned to civilian control. At this point, the future of communication seemed to favor wireless telegraphy over all other methods. The Navy realized that our country needed a national radio system, and they asked General Electric to take the lead in creating it. In response, G.E. and several other companies purchased the Marconi Company and formed the Radio Corporation Of America (RCA). For the time being, RCA continued the Marconi Company's Morse code work. Their goal was to make the underwater telegraph cables, and ultimately the entire telegraph system, obsolete. | ||

audio broadcasting voice stations In 1900, scientists discovered that audio sounds could also be transmitted by the Marconi method. Later that year, the first human voice was transmitted a distance of one mile. The first audio transmission of any great distance was achieved in 1906 and the first transatlantic audio transmission occurred in 1915. By the 1910s, several experimental audio stations (known as voice stations) were sending out unscheduled broadcasts of human speech, phonograph records, singers and violin players. (Visit my Entertainment page to learn about radio stations and programming!) who was listening? The first audiences for these broadcasts were wireless buffs and Marconi operators who were astonished to hear human speech and music coming through their headphones! There was a great deal of communication between the stations and their audiences. Listeners who built their own crystal sets were eager to help by being "listening posts" for experimental broadcasts. This was very exciting, especially for the many young boys who were becoming interested in radio at the time. | licensing When the Radio Act Of 1912 required the licensing of all wireless stations, it included voice stations, too. All audio stations were placed in the amateur or experimental categories and were given the appropriate call-letters. a visionary Although David Sarnoff worked as a Morse code operator at the Marconi Company, he also saw a bright future for the audio branch of wireless. In 1916, he wrote to the general manager in an attempt to persuade them to expand their operations: "I have in mind a plan of development which would make radio a 'household utility' in the same sense as the piano or phonograph. The receiver can be designed in the form of a simple 'Radio Music Box'....[listeners] could enjoy concerts, lectures, music, recitals, etc., which may be going on in the nearest city within their radius." Marconi management put his suggestion aside for later consideration. during & after the war When America entered World War I in 1917, the government suspended all amateur radio licenses and shut down the audio stations. On the battlefield, audio technology was used by the Army Signal Corps and was installed in airplanes for ground-to-plane voice transmission. In 1919, the wartime ban was lifted and experimental stations resumed broadcasting. Westinghouse engineer Frank Conrad reopened his home-based voice station 8XK, and his twice-weekly broadcasts became very popular in the Pittsburgh area. This gave Westinghouse the idea to start a commercial audio station of their own, which they would do in 1920. David Sarnoff's "Radio Music Box" Memo |
