Allied Radio: Hallicrafters Receivers, April 1941
April 1941 Radio News Article

April 1941 Radio News
April 1941 Radio News Cover - RF Cafe[Table of Contents]

Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

Little did Ham radio operators know in April of 1941 when they were enthusiastically buying equipment for their shacks that a year later the Federal Communications Commission (FCC) would ban them from broadcasting from their transmitters. This advertisement for a high-end Hallicrafters receiver appeared in the April issue of Radio News magazine. Part of the feature definition includes "calibrated bandspread inertia controlled," and "micrometer scale tuning inertia controlled." I'm not sure what the "inertia controlled" part is, unless it refers to how massive metal disks were sometimes installed inside the chassis on the tuning shaft in order to give a more solid feel to the control knob, as well as to enable the dial to be spun and released to rapidly move through a large distance between adjustment points. If you know for sure what it means, please shoot me a note (but don't just shoot me).

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 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...
