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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Electronics-Themed Comics

November 1947 Radio-Craft

November 1947 Radio Craft Cover - RF Cafe[Table of Contents]

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

Do you detect any (probably unintended) irony in the page 76 comic from a 1947 issue of Radio-Craft magazine? It shows a husband and wife shopping for a new radio and has the husband telling the salesman, "I don't care if it is FM - I want one that plays in the P.M.!" I'll let you think on it for a moment. As with many of the comics that appeared in the magazine, the scenarios were suggested by readers. The other comic played on the common music programming schedule that included times of "dinner music," "evening music," etc. If you like these comics, then you'll appreciate the huge list at the bottom of the page of others with tech themes.

Hint for the FM comic: Frequency modulation (FM) is related to phase modulation (PM) by an integral function. Both are forms of angle modulation. Get it?
