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

Here is a quick Hi−Fi Quiz for all you audiophiles out there. Although it appeared in a 1955 issue of Radio & Television News magazine, save for question #10 all of Q's and A's still apply to today's equipment. Even that one can be easily guessed. Q4 might seem a bit foreign, but think of the "groove" type as applying to 78, 45, or 33-1/3 rpm platters and you'll do OK. Question #7 could be a baffler (pun intended - you'll see how) were it not for one obviously invalid option that it takes an RF guy (or gal) to recognize its inanity. Good luck. BTW, I missed Q1, but should have known better.

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...
