 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 propulsion

In addition, 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.
