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...

RF Cafe Crossword Puzzle w/Weekly Headlines
February 5, 2017
|
|
For the sake of avid cruciverbalists amongst us, each week I create a new crossword puzzle that has
a theme related to engineering, mathematics, chemistry, physics, and other technical words. You will
never be asked the name of a movie star unless he/she was involved in a technical endeavor (e.g., Hedy Lamarr). Clues in this week's puzzle
with an asterisk (*) are pulled from this past week's (1/30 - 2/5)
"High Tech News" column on the RF Cafe homepage.
Enjoy!
