Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

At the end of World War II, much of the basic technology developed under the cover of secrecy was made available to the public for the purpose of stimulating research and development for commercial purposes. As with selling surplus material to the American public at significant discounts, the plan was to reward citizens for a five-year-long sacrifice in the effort to beat back the advances of Communism, Socialism, Marxism, and the other oppressive forms of "isms" around the world. History shows that the effort resulted in a major post-war era of prosperity and a general feeling of well-being by the country. This Sperry Gyroscope Company advertisement appeared in a 1946 issue of Radio-Craft magazine, promoting its development of gyroscopically stabilized marine radar. Other magazines of the era and into the 1970s frequently reported on commercial marine radars.

Look Ahead to/with Radar by Sperry

Sperry Gyroscope Company, April 1946, Radio-Craft - RF Cafe• This year, Sperry Gyroscope Company introduces its new Radar equipment for marine use.

Sperry Radar has been conceived to function better in this Fundamental service: To enable ships to operate on schedule regardless of visibility ... through thick fog, heavy rain, dense smoke, darkness.

As an aid to navigation it picks up channel markers and buoys; assists in making landfalls with assurance; spots icebergs, floating derelicts and other hazards projecting above surface. It also permits vessels to enter harbors and proceed with all due safety and caution 'through fog. Another important feature: Sperry Radar provides a Gyro-Compass-controlled image and can be operated by bridge personnel without extensive technical background.

In design and construction, Sperry Radar reflects this company's many years of experience in precision manufacture of marine equipment-as well as its outstanding achievements in the field of electronics. In simplicity and dependability, this new Radar exemplifies again Sperry's ability to build superior products for merchant ship service.

Sperry Radar Features:

• Designed to meet all Class A specifications of the U. S. Coast Guard.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

1996 - 2024


Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
