This week's wireless engineering-themed crossword puzzle, as is the case every week, contains only
words pertaining to science, engineering, amateur radio, physics, mechanics, mathematics, etc. Making
a special appearance is the name of the most recent company to support RF Cafe through advertising.
You will see their banner graphical ad appearing in the right page border sometime this week. Opportunities
exist for your company to advertise if you are
interested.
Reproduction of this puzzle without the express permission of RF Cafe is prohibited.
