BSEE - KB3UON

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...

Fire Devil Videoed

Australian photographer Chris Tangey caught this rarely seen "fire devil" on video. Just as a water spout is formed when a tornado touches down on a body of water and sucks water up into itself and a dust devil sucks up dust from the desert surface, this tornado landed on a brush fire and sucked the flame up into a 100-foot high towering inferno. Hence the name fire devil. I wonder why water spouts aren't called water devils?
