 "The Radio Month" was a regular industry
news briefs feature of Radio−Electronics magazine." In 1951 when this issue
was published, nearly all computers were of the analog variety. The monstrous (in
size) UNIVAC digital computer was not commissioned into operation until March of
the same year (1951). Leading the report this month was
Project Typhoon, an analog computer developed by RCA. It sported more than 4,000
vacuum electron tubes with 100 user-adjusted dials and 6,000 plug-in connectors
or use in programming. According to the book The Analogue Alternative, "Project
Typhoon was justifiably described as a 'veritable fountain head of improved computing
elements.' One of the most important developments to come out of Project Typhoon
as the invention of the chopper-stabilized, or drift-free, DC operational amplifier
by E.A. Goldberg." In other news, new deposits of germanium had been discovered
in New Jersey, of all places. Silicon had not yet become the dominant semiconductor...

 Min Zang has a useful article on the In Compliance
website entitled "Capacitors:
Theory and Application," which is a good primer on what a capacitor is, how
it works, and what it it used for. It begins: "Capacitors are among the most commonly
used components on a circuit board. With the ever-increasing number of electronics
devices (from mobile phones to cars), there has been a growing demand for capacitors.
A discussion on the subject of capacitors could easily become a book or a dictionary.
To start with, there are different types of capacitors such as electrolytic, film,
ceramic capacitors, and so on. Then, within the same type, there are different dielectric
materials. There are also different classes. As for physical construction, there
are two-terminal and three-terminal capacitor types. There's also an X2Y type capacitor
which essentially is a pair of Y-capacitors packaged in one. What about supercapacitors?
The fact is, if you sit down and start reading the capacitor selection guide of
major manufacturers, you could easily spend a day..."
 Rohde & Schwarz announced the launch
of the high performance R&S
ADD557SR direction finding and monitoring antenna system. The system provides
accurate direction finding capabilities across a wide bandwidth from 20 MHz to 6
GHz for both vertical and horizontal polarizations. It is ideal for R&S DDF550
wideband direction finders and R&S DDF5GTS high-speed scanning direction finders.
The new direction finding antenna system incorporates the latest technologies, making
it a high-end, versatile device for stationary and mobile applications on land,
at sea and even in the air. This new antenna system is one of a kind and can do
more than just direction finding. The R&S ADD557SR incorporates a separate antenna
output that can be used independently of direction finding and in both polarizations
over a wide frequency range. This helps focus on certain signals in the spectrum...
 The first electronic circuit I remember building
as a budding teenage tinkerer was a
"whistler" detector, aka a "sferic." Instructions and a schematic came from
a project book I bought at Radio Shack. A whistler is a time-varying electromagnetic
signal that decays in both frequency and volume over a short time - like sounds
made by the eponymous fireworks genre. Having always had an interest in weather
phenomena as part of my flying hobbies, it seemed like an apt learning endeavor.
To my recollection, the whistler detector was a simple diode circuit with a couple
Rs, Ls, and Cs strewn around in a particular configuration, and a long wire antenna.
I can't honestly say whether or not any whistlers were ever heard with it. My interest
was a layman's curiosity, but elsewhere in the world, professional scientists were
expending a lot of effort in their attempts to analyze and quantify a whitler's
particulars...

 David Sarnoff was the president of
Radio
Corporation of America (RCA) during the war years (WWII), and in fact was commissioned
in 1924 into the U.S. Army with the rank of lieutenant colonel. During WWII, he
served in the office of the Chief Signal Officer in Washington, D.C., and in 1944
he was reinstated and promoted to brigadier general, going overseas to serve as
Special Consultant on Communications to General of the Army Dwight D. Eisenhower
at SHAEF in Europe. He directed strategic and logistical communications across all
theaters of operation (Europe, Pacific, and Northern Africa). It is no surprise,
then, that RCA played a huge role in the war effort providing both components and
systems. This 1942 full-page promotion in Radio News magazine touting RCA's contributions
and encouraging all citizens to do all he/she could is typical of those seen in
the era...
 "Magnetism and superconductivity are usually
at opposite ends of the spectrum in condensed-matter physics. For them to appear
in the same material is exceedingly rare. Yet that is exactly what Jia Li and colleagues
at Brown University in the US found when they interfaced so-called
'magic-angle' graphene with a second two-dimensional material, tungsten diselenide.
Thanks to a complex interaction between the two materials, the researchers succeeded
in transforming graphene from a superconductor into a powerful ferromagnet - an
achievement that could give physicists a new way to study the interplay between
these two usually separate phenomena. Graphene is a 2D crystal of carbon just one
atom thick. Even on its own, this “wonder material” boasts many exceptional properties,
including high electrical conductivity as charge carriers (electrons and holes)
zoom through the carbon lattice at very high speeds..."
 Here is what an app looked like in 1930.
Even in today's world with computing devices everywhere sporting simulators and
component calculating programs, there are still times when having a good old fashioned
nomograph or chart handy can be very useful while in sitting at a bench selecting
component values for tweaking or troubleshooting a design. The advantage of such
visual aids is that they provide a big picture of what's happening as frequencies,
lengths, widths, core materials, etc. change - being able to see both the trees
and the forest, so to speak. When you are working in bands where the component physical
size is a significant portion of the wavelength, things get more complicated and
a combination of trial and error and calculations / simulations are needed. At the
IC design level, of course, you have no choice but to rely solely on your computer,
but if you regularly conduct part of your circuit design at a lab bench, I recommend
gathering a collection of these kinds of charts and graphs...
 Copper Mountain Technologies is pleased
to announce an online event coming up as part of our VNA Master Class Webinar series:
"Non-Destructive
Microwave Evaluation of Radome Performance." Hosted by Copper Mountain Technologies
and Compass Technology Group, the webinar will be taking place on Wednesday, February 23,
2022 at 10:00 AM ET. Radomes can experience defects due to wear or impact
events that degrade both mechanical and electromagnetic performance. Traditional
radome testing often resorts to the crude "tap test" where an operator listens for
sound changes with a tapping coin to detect defects. CTG has developed new and improved
methods that integrate rugged microwave sensors and Copper Mountain's portable VNAs
to significantly improve diagnostic testing of radomes. This webinar will provide
a brief overview of the theory of microwave NDE methods for radome characterization.
We will then demonstrate both handheld and robotic testing of radomes...
 When becoming a licensed Ham a few years
back, I learned that when broadcasting over amateur bands, the FCC requires you
to transmit your station identification at the beginning of each session and then
at least once every ten minutes. I hate to nit pick a "Carl &
Jerry" story, but in this episode John Frye's intrepid electronics hobbyist
duo rigs up their basement "shack" to automatically transmit the letter "A" in Morse
code as a beacon signal to test reception in a cave. A timer would start the broadcast
and it would run continuously for half an hour. Maybe things were different in 1961.
The experiment intended to test a signal's ability to propagate through the Earth
rather than through the air. It is an interesting twist on the skin effect of high
frequency signals along a conductor. As you might suspect, the plan did not go exactly
as intended, requiring Carl and Jerry to apply a bit of radio knowledge to get themselves
out of peril...
 It was a lot of work, but I finally finished
a version of the "RF & Electronics Schematic & Block Diagram Symbols" that
works well with Microsoft Office™ programs Word™, Excel™, and Power Point™.
This is an equivalent of the extensive set of amplifier, mixer, filter, switch,
connector, waveguide, digital, analog, antenna, and other commonly used symbols
for system block diagrams and schematics created for Visio™. Each of the 1,000 or
so symbols was exported individually from Visio in the EMF file format, then imported
into Word on a Drawing Canvas. The EMF format allows an image to be scaled up or
down without becoming pixelated, so all the shapes can be resized in a document
and still look good. The imported symbols can also be UnGrouped into their original
constituent parts for editing. Check them out!

Thursday the 10th
 It has been a couple weeks since I last
posted any of the
electronics-themed comics which frequently appeared in the vintage trade magazines.
This sextet od comics came from the November and December 1961 issues of Radio−Electronics.
I particularly like the first one from page 99. It depicts a great The Three Stooges
type scenario. The comic from page 107 was ahead of its time in prognosticating
electronic one-armed bandit machines. You would need to be familiar with the days
of CRT televisions and the picture alignment process to fully appreciate the one
on page 108. Anyway, feel free to include any of these or the hundreds of others
linked at the bottom of the page in your next live presentation. They're a great
segue into your next spiel on project progress (or lack thereof) or design techniques...

 That 7.5% increase in
consumer prices from
January 2021 through January 2022 is the average across all indexed items - highest
since 1982 Carter era (some of us are old enough to remember that awful time). That,
per the new Bureau of Labor Statistics (BLS) report. However, overall energy costs
are up 27% and gasoline is up 40% (we went from energy independence and net exporter
to primarily importer since January 2021).
 Cargo ships sit offshore waiting to be unloaded
at port while store shelves are bare. Basic
building materials
costs are up 50% or more (framing lumber up 100%, Romex wire up 150%), and
department store prices
are up 20% or more (see graph).
Anyone have an idea about what might be the cause of this rotten situation?

 McWatts was an electronics-themed comic that
appeared in Popular Electronics magazine back in the 1950s. Artist Carl
Kohler's main character is a stereotypical "Joe Sixpack" type of electronics hobbyist
who dreams up unique ways to deal with situations. This edition shows McWatts in
a scenario where, presciently enough, he experiences having his radio controlled
airplane treated to what modern day "drone" pilots are experiencing on a more and
more frequent basis - being shot down. In this case the hostile fire came from some
kids with slingshots. Fast-forward to 2015 and we are now seeing reports of people
using shotguns and rifles to down the privacy-invading craft being piloted by unqualified
pranksters. Back in the McWatts era, getting "shot down" was much more likely to
occur when non-protected frequency usage (27 MHz band intermixed with the CB
radio band) caused death-inducing interference...

 My daughter dragged me to an estate sale
last weekend, and while there I found a stack of World War II era Life
magazines, many of which had some useful articles on chemistry, electronics, and
other subjects pertaining to technology being used to fight the battle against Communism,
Nazism, Socialism, and other "ism's." This 2-page spread entitled "CHON - Four Elements
Chart the Laws of All Chemistry" appeared in the March 23, 1942 issue. Today, such
a diagram would be called an infographic. It explains the relationship that Carbon,
Hydrogen, Oxygen, and Nitrogen (CHON) has with all the essential products and reactions
in our everyday world. One modification to the article might be to increase the
claim that only 20 out of the known 92 elements (at the time) comprise the makeup
of the "vast bulk" of matter. While it doesn't explicitly name the 20, some elements
like lithium (batteries), gallium, and arsenic (GaAs) now have a very large presence
in the world's economy and might not have been so important in 1942...
 "The National Institute of Standards and
Technology (NIST) has started working on measuring the
effect of trees on millimeter waves to improve the connectivity of future 5G
antennas. As 5G technology gets fully implemented over the next several years, cellphones
and other wireless tech will grow more powerful with increased data flow and lower
latency. But along with these benefits, there are a number of challenges that need
to be overcome. One such challenge is signal propagation at mm-Wave frequencies
and the impact of obstacles in the propagation path. That's one way to describe
the problem confronting cell network designers, who have to embrace both the benefits
and shortcomings of millimeter waves. Not only can these waves carry more information
than conventional transmissions do, but they also usefully occupy a portion of the
broadcast spectrum..."
 Here is yet
another example of how hobbyists laid the groundwork for technical innovations that
were eventually adapted for use and improved by professional organizations - the
military, universities, corporations. Radio control of model airplanes was first
successfully achieved by a pair of brothers, Dr. Bill Good and Dr. Walt Good (kind
of like the Wrights), who experimented with what were at the time rather crude engines
and electronic and electromechanical devices. The year was 1936, only eleven years
before this article appeared in Radio−Craft magazine reporting on the U.S.
Army Air Force's and Navy's use of radio-controlled drones, or as the title says,
"Teleguided
Missiles." Some systems were designed from the ground up to be missiles while
others were systems installed in existing aircraft which had been decommissioned
for normal human-piloted use. They were sort of a Kamikaze craft without the expendable
airman inside...

 Complete with all the nitty-gritty details
and necessary formulas for designing an
inductive loop coupler for a rotating antenna is this 1950 QST magazine
article by Mr. Robert Mumma. Such a device is useful when you desire a steerable
antenna that prefers not to or cannot accommodate a section of coaxial cable interfacing
the fixed mast to the rotating antenna. It is rare that such a requirement is found,
since installing a set of limit switches to prevent the cable from wrapping itself
around the mast is relatively simple to implement. However, if you want a system
that continually rotates while searching for or broadcasting signals, then something
like this is needed. A radar antenna is a prime example, as would a search and rescue
operation using a directional antenna listening to distress calls be another. There
is also a "cool factor" that might cause you to build and install one...

 As someone who, many moons ago as an electrician,
made lots of service calls to both households and businesses, I am somewhat familiar
with the whims and quirks of strangers who have summoned you to his or her place
in order to be serviced. Most are courteous in a business-like manner and expect
you to get the job done in the most efficient and effective manner as possible in
order to keep the cost down. Time and material is the usual modus operandi for service
calls. On occasion a customer would stand around and talk about the job at hand
- what caused the problem, how it would be repaired, and how to avoid a repeat in
the future. Others were just gabby, which I didn't mind as long as it didn't get
in the way of completing my appointed task. The problem comes when the person acts
like you are to blame for whatever bedevils them and nothing you do is good enough,
whether you are presumably too slow, too stupid, too unwilling to take sage advice,
etc. Those types are the bane of a serviceman's existence. Do the world a favor
and determine you will never join their ranks...

 Evidently the procurement cost of promethium
147 never fell low enough to make it affordable by the masses. If it had, though,
according to this 1957 Radio & TV News magazine article we might all
have been wearing nuclear-powered
Elgin National Watch Company timepieces in the last century rather than Timex.
Beta particles from the radioactive decay of promethium 147 impinge upon special
crystalline components that generate enough electricity in this cell to power a
watch for five years or more. I wonder, had it been successful, how long it would
have been before 'that persistent rash' on people's wrists and upper thighs (for
pocket watch users) was determined to be due not to a metal allergy, but to a radiation
burn? It is amazing such schemes were ever considered, but then again I still have
dental fillings with lead amalgams in them...

 "Using large-area electronic fabrication
techniques, a team has constructed and tested a three-element
GHz-range phased-array antenna. Phased-array antennas are taking on increasing
roles in MIMO systems such as 5G, as they can provide needed dynamic, all-electronic
antenna steering and directivity. However, they have an attribute that complicates
their physical and electrical fabrication - they're composed of multiple identical,
discrete antennas elements with form factors that aren't amenable to mass-production
techniques. Responding to this dilemma, a team based at Princeton University devised
and tested a technique for creating electronically steerable, GHz-range phased-array
antenna assemblies as large-area electronics (LAE). They applied fabrication processes
used for electronic circuits on thin, flexible materials..."
 I'm guessing once word got out about the
Fusite advertisement in the 1945 edition of Radio News magazine, there
was a sudden surge of interest in buying electronics magazines by young boys who
also collected certain editions of National Geographic. Even by today's
rather loose decency standards this mermaid depiction would undoubtedly cause an
outcry. Imagine my shock in turning to page 90 and seeing this illustration! Why,
I had to stare at it for many minutes to believe what was before my tender eyes
;-) Of course since RF Cafe is a family friendly website I did the responsible thing
and blurred the offending anatomical portion of
Cincinnati Electric Products Company's aquatic vamp. I checked the "Letters
from Our Readers" column for the succeeding few months and did not see any complaints
printed. Neither did I see that ad appear again...
