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...

So Quite, You Can Hear a Snowflake Drop

Looking for the quietest place on Earth? It's at the South Pole - at least from a seismographical perspective. Researchers have operated seismic instruments there since 1957, but, as with urban sprawl in warmer climes, the noise level has grown worse with the population of that area because of new researchers moving in. No worries (a little Dundee lingo there), new locations have been established in 300 meter deep bore holes about 8 km from the old site. Sensitivity is 100 times that of the previous detectors, and 4 times that of anywhere else on Earth. So, when the San Andres Fault finally starts letting go, they'll be the first to know about it.
