For more than a decade, I have been posting these Radio Service Data Sheets for
radios and various other audio and visual electronics sets that appeared in vintage
electronics magazines. This one for the Atwater Kent
Model 649 all-wave, 9 metal tube, superheterodyne console radio set was published
in the November 1935 issue of Radio Craft magazine. "All-Wave" radios were popular
at the time because they provided access to shortwave bands so listeners could tune
in foreign broadband stations - often with the rudimentary built-in antenna.
Short
wave listening was actually a worldwide sport that had its own cadre of enthusiastic
participants, including a dedicated magazine entitled
Short Wave Listener. Tuning into the audio portion of
television broadcasts was a big deal as well. Although not as popular today, there
are still a few adherents remaining.
Atwater Kent Model 649 All-Wave 9 Metal Tube
Superhet. Set
 The airplane dial of this set changes illumination
as the bands are shifted. Both halves are lighted on the broadcast band. the upper
half on the S.-W. band, and the lower half on the police band. The tuning ratio
is 60-to-1 on the high position. The selectivity control makes possible true high-fidelity
when in the low selectivity position. In addition, a 4-position tone control is
used. Correct tuning is shown. by observing the shadow tuning meter, which is operated
by the plate current of V2 and V3. The set draws 120 W. from the line. The range
switch has 3 sections, each of which changes 3 separate circuits.

Arthur Atwater Kent: A Biography |
Electronics Pioneers & History
- See Full List of AI Topics -
 Atwater Kent was an American inventor, entrepreneur and manufacturer of radio
equipment. He was born on December 12, 1873, in Cassopolis, Michigan and died on
August 30, 1949, in Philadelphia, Pennsylvania. He was a pioneer in the
development of radio technology and his impact on the industry is still felt
today.
Kent began his career as an electrical engineer, working for various
companies before starting his own business in 1918. He founded the Atwater Kent
Manufacturing Company in Philadelphia, Pennsylvania, with the goal of producing
high-quality radio sets for the public. The company quickly became one of the
largest radio manufacturers in the United States, producing over one million
radio sets between the 1920s and 1930s.
One of Kent's innovations was the development of the "breadboard" radio set,
which was easy to assemble and repair. He also made use of more efficient
components, such as high-voltage power supplies, which allowed his radio sets to
produce better sound quality. His radios were also known for their beautiful
wooden cabinets, which were handcrafted and came in a variety of styles and
finishes to suit any decor.
Atwater Kent was a visionary who understood the potential of radio as a means
of communication and entertainment. He was an advocate for the development of
commercial radio broadcasting and he supported the establishment of the National
Broadcasting Company (NBC) in 1926. This network helped to bring radio to a
wider audience and it was a major factor in the growth of the radio industry.
In addition to his contributions to the radio industry, Kent was also a
philanthropist. He supported a number of educational and scientific
organizations, including the Franklin Institute, and he established the Atwater
Kent Foundation, which provided grants for scientific research.
