 This
RF Engineering Theme crossword puzzle for January 31st contains only words
and clues related to engineering, mathematics, chemistry, physics, and other
technical words. As always, this crossword contains no names of politicians,
mountain ranges, exotic foods or plants, movie stars, or anything of the sort
unless it/he/she is related to this puzzle's technology theme (e.g., Hedy
Lamarr or the Bikini Atoll). The technically inclined cruciverbalists amongst
us will appreciate the effort. You will need to print out a hard copy. Enjoy!
Friday the 29th
 A little while back I mentioned that
Melanie, my XYL of 38 years, out of the clear blue sky announced that she
might like to earn her amateur radio operator's license. If I'm not mistaken,
it was after she OCR'ed this article entitled, "A
'Ham's' Wife Confesses," from a 1938 issue of Radio News magazine where
Mrs. Dorothy Hagerty decided to earn her ticket. Over the many years
of performing such duties for articles I select from my many hobby and professional
magazines to post here on my RFCafe.com and AirplanesAndRockets.com websites,
Melanie has seen a score or more of similar articles where a wife decides
to join in on her OM's pastime. Some have learned to build and fly model airplanes
and helicopters, to skipper R/C sailboats, race drones, and to outfit and
operate Ham shacks. Melanie is still working through the Level 1 Technician
ARRL Ham Radio License Manual. We've been working on test equipment usage
(o-scope, analog and digital VOM...

 "The first full-electric power and

Navy. The

machinery layout is more flexible and configurable. GE's Power Conversion
business was the designer and provider for the high-voltage system (HV), propulsion
drive trains consisting of multiphase converters and Advanced Induction Motors
(AIM) for the DDG 1000 class of futuristic destroyers. 'Delivery is an important
milestone for the Navy, as the DDG 1000 continues more advanced at-sea testing
of the Zumwalt Combat System..."

 For some reason, making people speak
like country bumpkins was deemed good humor back in the early to mid twentieth
century. To wit, Li'l Abner, Snuffy Smith, Barney Google, et al, had characters
that made the Beverly Hillbillies look like Rhodes Scholars by comparison.
This fun story entitled, "Them Wuz the Good Old Days..." in the July 1944
edition of QST is no exception. Enjoy.
