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...

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

Remember when you could hold a telephone conversation without having to allow a moment of time at the end of a sentence before responding in order to keep from 'stepping on' the person on the other end? It used to be only overseas phone calls or maybe communicating to astronauts on the moon suffered such inconveniences, but talking to someone across town was like having a face-to-face discussion. More often than not - or so at least it seems - there is a noticeable delay between the time someone actually stops talking on the transmitter end and the time the audio stops at the receiver end. People who have never known otherwise accommodate the delay with no perception of how good phone calls used to be.
