Wireless Engineering Crossword Puzzle
July 31, 2016
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.
