The Astatic Story

The following was excerpted from the 1946 Astatic Catalogue.

AN IDEA  that grew into an Industry

The D-104, Astatic's first Crystal Microphone manufactured in 1933

Away back in 1930, two radio amateurs, C. M. Chorpening, W8WR (now W8MJM), and F. H. Woodworth, W8AHW, both of Youngstown Ohio, began searching for a better microphone for their phone transmitters. Up until this time they had been using various carbon type microphones. The condenser type appealed to them as an answer to their problem. Several units were designed and given trials on the air. Before long, other amateurs among their acquaintance began visiting their shacks, interested in either building or buying this new type of "mike." Chorpening and Woodworth, encouraged by this interest, decided to form a partnership and build these units for their friends. While the condenser unit proved reasonably satisfactory, it had certain limitations which it was hoped could eventually be overcome.

NEW ELEMENT SUGGESTED

It was about this time that an old acquaintance, Mr. Charles E. Semple of Cleveland, who had been visiting his "ham" friends frequently, invited them to pay him a visit. With a background of phonograph and loud speaker experience, Mr. Semple was then occupying bench space in the Brush Laboratories, experimenting with elements made from Rochelle Salts, (Sodium Potassium Tartrate). Through Mr. Semple, the two visitors met A. L. Williams, electrical and mechanical engineer, and Dr. C. B Sawyer, scientist, who demonstrated the action of these new elements in relation to microphones, phonograph pickups, speakers, recording heads, earphones and other devices where it was desired to transform mechanical energy into electrical energy or the reverse. Here, it seemed, they had found the answer to a simple, low-cost, dependable "mike" for the "ham rig."

INCORPORATED IN 1933

By 1933, CHorpening and Woodworth found it advisable to incorporate a manufacturing and sales company and to branch out with a line of Crystal Microphones, Crystal Phonograph Pickups and Recording heads for manufacturers and Radio Jobbers. Mr. Semple was brought into the new organization as designer and later served as general manager until his death in 1939.


There is certainly a lot of missing information from 1933 to 2011,

The item most overlooked when ordering a custom radio is the microphone.  Your new tuned radio will NOT
sound great  with a stock mic on it  If your CB is more than a tool for work, you NEED to upgrade your microphone. 
My personal favorites are the Astatic 636L and RD104E.

If you place an order from outside the continental USA, we will calculate your actual shipping and send you a PayPal payment request.  We do NOT export Antennas or Base station radios.
