    Kirt Blattenberger,


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...

Wireless Engineering Crossword Puzzle
February 28, 2016

I have a confession to make regarding the puzzle titles. While all RF Cafe crosswords do in fact use only my hand-entered dictionary of terms and clues (literally thousands accumulated over the years) that pertain exclusively to science, engineering, chemistry, physics, mathematics, astronomy, etc., the choice for a particular title is to help attract search engines to the page. There is nothing deceptive going on, just an attempt to exploit the nature of search engine algorithms that rank pages based on meta tags coinciding with relevant keywords and phrases occurring on the page. Enjoy.

acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words
