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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

August 1944 Radio-Craft[Table of Contents]
People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Radio-Craft was published from 1929 through 1953. All copyrights are hereby acknowledged. See all articles from Radio-Craft.
Major Armstrong, outstanding pioneer, was last month awarded a Certificate of Appreciation by the Signal Corps in recognition of the valuable work he is now doing for the United States. Definitely, the citation was for "outstanding contributions to the Signal Corps, Army Service Forces." Armstrong was further honored in that the certificate to him was the first one of its kind to be issued.
It is the intention of the Signal Corps to present such certificates to individuals and companies who have performed notable services beyond the normal requirements of duty but who are not under the direct control of the War Department and are therefore, not eligible for the Army-Navy "E."
Dr. Armstrong's contributions to this war began in 1941, when he waived all his royalties on the use of 17 patents covering FM apparatus used by the War Department. At the same time he offered to license any manufacturers designated by the War Department to produce apparatus under his patents for use during the present emergency, at the rate of one dollar a year per patent.
This is not the first time Dr. Armstrong's efforts have been of value to the War Department and the radio public. It was as a Signal Corps officer in France during the last war that he developed the super-heterodyne circuit, now used in practically all broadcast receivers. Later he originated the super-regenerator, commonly used in ultra-short-wave reception, and as a crowning triumph, brought out (in 1934) his latest invention, FM, which has already revolutionized standards of broadcast reception.
