A Christmastide Muddle

Merriam-Webster defines Christmastide as "the festival season from Christmas Eve till after New Year's Day or especially in England till Epiphany." In 1930 when this article appeared in Radio-Craft magazine, most likely everyone knew what Christmastide was, but not so much today. While reading and scanning vintage magazine articles throughout the year, I set aside ones specific to holidays like Christmas, Thanksgiving, Halloween, etc., and post them during their respective seasons. This story is about the trouble caused by a well-meaning but unqualified family member attempting to fix a radio that wasn't broken by gifting dear old Dad a Balkite trickle charger (radiomuseum.org has one) for his battery-powered radio set. It also mentions using a potato to test the DC polarity of a power supply or battery...

Flying Saucers - Myth or Fact?

Here is a very timely article entitled, "Flying Saucers - Myth or Fact?," which appeared in a 1964 issue of Radio-Electronics magazine. The recent rash of unidentified flying objects over parts of New Jersey, Wright-Patterson AFB, and a few other key locations has resurrected an interest in whether "UFOs" exist. Despite hundreds of reports of what appear to be large drones, the government insists they are not U.S. or foreign military equipment. They specifically do not deny that they belong to some U.S. government agency - like Homeland Security, FBI, CIA, etc. Conjecture that they are "nuke-sniffing" drones searching for missing fissionable material. Regarding UFO video recordings, have you noticed how with all the high tech cameras out there that there has never been a clear, up-close picture of one? Those glimmering "orbs" in videos is clearly the planet Venus in the evening sky right now...

Engineering Salary & Career Survey 2024

Salaries trend up for electrical and electronics engineers in 2024 per this Electronic Design magazine survey -- mine has been going down for years :{ "In a tight labor market, skilled engineers continue to have leverage when negotiating salaries and pushing for bonuses and other perks. In 2024, the median income of electronics engineers and other tech professionals who responded to the survey is in the range of $125,000 to $149,999. The survey revealed that slightly more than 20% of engineers expect to earn between $150,000 and $199,999, excluding bonuses, overtime pay, and other earnings over and above their base salary...

Yagi–Uda Antenna

The Yagi–Uda antenna,, often referred to simply as the Yagi antenna, was developed in the late 1920s by Japanese engineers Hidetsugu Yagi and Shintaro Uda at Tohoku University in Sendai, Japan. The primary motivation for their work was to design a highly directional antenna capable of efficiently transmitting and receiving radio waves over specific frequencies. This need arose as radio communications technology was rapidly advancing, with an emphasis on improving signal strength and selectivity for applications in research and burgeoning communication systems. Mssrs. Yagi and Uda sought to enhance the performance of basic dipole antennas by creating an array that exhibited improved directivity and gain. ..

Electronic Crossword

Margaret LeFevre created a handful electronics-themed crossword puzzles for the July 1961 issue of Electronics World magazine. Crosswords have been around for at least two centuries and come in many formats from having both x- and y-axis symmetry to symmetry about only one axis or even no symmetry at all. They can be square, rectangular, or have special shapes. This particular one has partial symmetry about the y-axis. Note that it is composed of two isolated regions with no open path between the regions. If you enjoy working crossword puzzles, there are plenty more which I have posted from electronics magazines, plus I have...

Electronic Failures in Space

By the time editor Hugo Gernsback wrote his "Electronic Failures in Space" article for the April 1964 issue of Radio-Electronics magazine, half a decade had passed since the official end of the International Geophysical Year (which was actually 18 months long). Much new knowledge had been gained and theories confirmed regarding the environment electronics would be exposed to not just while above the atmosphere, but also while passing through it. Oh, and the extreme vibration and acceleration during the launch and boost phases to get into space were no piece of cake to accommodate, either. Fortunately, a lot of immensely smart and dedicated people worked out the bugs one by one, and we have arrived at a vastly advanced...

MESFETs on Single Crystal Aluminum Nitride

"Arizona State University (ASU) in the USA reports on high-voltage aluminum nitride (AlN) metal–semiconductor field-effect transistors (MESFETs) on single-crystal AlN substrates. The researchers claim their work as the first report of 'AlN transistors via homoepitaxial growth on native substrates.' The team comments: 'The devices showed good saturation and pinch-off behavior with high maximum Ids, gm and on/off ratio compared with AlN-on-sapphire devices without complicated contact layers.' AlN has the highest breakdown electric field, 12MV/cm..."

Semiconductor Boules

The history of growing semiconductor boules is a cornerstone of modern electronics, marking advancements in material science and technology that have propelled numerous industries. Boule growth processes have their roots in the early 20th century, when researchers first sought to create pure semiconductor materials for experimental purposes. Initially, materials such as germanium (Ge) and silicon (Si) were used, with silicon ultimately becoming the most prevalent due to its superior properties and availability. Germanium was the first material used extensively in semiconductor applications, as its electronic properties made it suitable for early transistor designs. The Czochralski process, developed in 1916, was adapted for germanium and later silicon. This method, involving the slow pulling of a seed crystal from molten material, remains fundamental to boule growth today. Silicon's dominance...

Side-Looking Radar Imagery

Side-looking airborne radar (SLAR) started out using a narrow beam formed by reflectors, like traditional radars, as opposed to the synthetic aperture type most often used today. Both types of side-looking radars rely primarily on the physical movement of the airborne platform for effective azimuthal scanning rather than steering the beam either mechanically or electronically. This 1965 Electronics World magazine article represents early versions which used "real aperture" antennas. Modern computer-controlled synthetic aperture radar beams can be segmented and directed off-axis for detected...

How to Build a Crossover Network

Did I ever bore you with my experience building a crossover network for a set of medium power speakers (about 100 watts each) when in the USAF? Too bad I didn't have this "How to Build a Crossover Network" article from a 1968 issue of Radio-Electronics magazine handy. I'll spare you the details, but the era was 1979, and I was in tech school at Keesler AFB studying to be an Air Traffic Control Radar Repairman. Being amped up (pun intended) with electronics theory with both semiconductor and vacuum tube circuits, I was looking to cobble together a nice amplifier and a set of speakers. Back in the day, it was possible to buy the components...

Immersion Silver Surface Finish

San Francisco Circuits, a premier provider of leading edge technology printed circuit boards, has published a new article on the Immersion Silver Surface Finish process, also known as immersion Ag. It is an RoHS compliant (lead-free) PCB surface finish offering exceptional flatness and cost efficiency. This surface finish is particularly well-suited for fine-pitch components and can replace Immersion Gold over Electroless Nickel (ENIG) in many applications. Unlike ENIG, Immersion Silver applies directly to copper without requiring a diffusion barrier. It's an excellent choice for applications that must avoid magnetic...

Electronics-Themed Comics

Here are a couple high tech comics for your enjoyment from the pages of the July 1961 edition of Electronics World magazine. I'm guessing the joke in the page 72 comic is that unknown parts were/are generically referred to as "Brand X," so hopefully that would bring in customers who couldn't identify components (which the repairman probably could). The page 94 comic is yet another play on the huge popularity of home hi-fidelity (hi-fi) sound systems of the day. Amplifiers still used vacuum tubes so building speaker driver circuits that could handle hundreds of watts was easy to do. Finding speakers to handle that power (and getting neighbors to tolerate...

"Merry Christmas and Happy New Year" Around the World

In case you are wondering, here is how you would write "Merry Christmas and Happy New Year" in the world's most prominent languages. While not everyone celebrates the birth of Jesus, most recognize the holiday spirit during what we call the Christmas Season. This image includes the same hopeful and grateful message to everyone. Thanks to all of you who has helped make RF Cafe a success since 1999!

RF Cafe Podcasts

At the prompting of others, I decided to give podcasting a try. Having been advised that I have a face for radio and a voice for print, there was some hesitation on my part. However, there have been many fine articles published in vintage electronics magazine that people might be willing to listen to when there is no opportunity or desire to read them. Regular features such as "Carl & Jerry," "Mac's Radio Service Shop," editorials by the great Hugo Gernsback, and other types that do not contain images which need to be referred to in order to get the gist of the content, are prime targets for podcast listening. If the podcasts prove to be popular enough, I will expand to a paid subscription...

What's Your EQ?

Another triplet of electronics circuit challenges here for you from a 1962 issue of Radio-Electronics magazine - a resistor network, a voltage divider, and a delayed switching circuit. As is usually the case with the resistor network, rearranging the circuit branches into a more familiar configuration simplifies its analysis. That is a good general rule when analyzing any circuit - rearrange and break down into recognizable subcircuits. The series circuit is about as simple as it gets, but knowing about how an ammeter is constructed helps. The Delayed Switching challenge is a little misleading in its description since the proposed solutions does use a vacuum tube duo diode (aka dual diode or full-wave diode) as part of the power supply circuit, although...

QST Christmas Covers

As our traditions are besieged by malcontents determined to denigrate, impugn, and ultimately erase memories of holidays and events that have meant so much to families and friends, I feel compelled to resist the movement by documenting parts of the past that will cause us to wax nostalgic over our cherished traditions. Intimidation and violence is part of the strategic calculus; we have seen it in spades in 2020, and 2021 promises to be even worse. The Cancel Culture might eventually win out with the complicity of government agents both elected and unelected, but I'm not going down without a fight. Here is a collection of twentieth century, December issue QST magazine covers with Christmas themes that will no doubt be familiar to many of you. Finding them was more difficult...

John T. Frye: A Short Biography

John T. Frye, born on March 14, 1910 and passing on January 31, 1985, was a celebrated author, electronics enthusiast, and technical writer whose work left an indelible mark on the world of radio and electronics. According to historical records, he was stricken with polio as an infant, which left him physically disabled and confined to a wheelchair. Despite this early adversity, Frye demonstrated extraordinary perseverance and creativity, becoming one of the most prolific and beloved contributors to technical literature during the mid-20th century. John T. Frye's career as a writer began to flourish in the 1940s and 1950s, when he penned numerous articles, instructional guides, and serialized stories that combined entertainment with education. Among his most iconic works were the Carl & Jerry stories, which ran for many years in Popular Electronics magazine...

Drones Shut down Wright-Peterson AFB

"Unknown drone activity forced one of the U.S.'s most critical military installations to shut down for several hours late Friday evening and Saturday morning, officials confirmed. The incident prompted heightened security measures and temporarily halted operations at Wright-Patterson Air Force Base in Ohio. Home to the 88th Air Base Wing, Wright-Patterson is one of the largest and most strategically important bases in the U.S., tasked with advanced research, intelligence, and operations. Unauthorized drone activity in military airspace poses significant risks, from espionage to safety hazards. In audio recordings by the Air Force Base air traffic control, which were shared online, an operator can be heard saying they are diverting 'over base' air traffic..."

What is Q?

"Q" is an often used term to describe the electrical "quality" of a circuit or component, and for the most part anyone engaged in the conversation (verbally or via reading) understands the concept. However, having a firm grasp on the technical ramifications is required if you happen to be a circuit or system designer and need to conform to certain specifications. "Q" can be good or bad, depending on your needs. If, for example, you need a narrowband receiver to reject adjacent signals or you are designing a high stability and spectrally clean oscillator, then you want all the "Q" you can get. On the other hand, if your goal is to receive a spread spectrum signal or generate white noise across some bandwidth, then a lower "Q" is what...

Carl & Jerry: Improvising

Whoa! John T. Frye really outdid himself in dreaming up a Rube Goldberg electronics contraption in this 1960 "Improvising" episode of his Carl and Jerry technodrama series in Popular Electronics magazine. I have wondered whether he actually proves these concepts by building what he describes the boys doing; it wouldn't surprise me if he did. Even if the devices are purely theoretical, the description of the thought process and method of practice is impressive. This being the beginning of the snow season in the northern realm, the story's setting in a crippling snow storm is timely. It was potentially a life-or-death situation, which triggered the classic "necessity is the mother of invention" reaction...

Ripple Filter Design Chart

Even in this age of a prodigious supply of computer programs and mobile device apps (OK, apps are also computer programs) to calculate circuit component values and responses, having a cool graph to look at can take a lot of mystery out of the results. Depending on the sophistication of your software, calculated values can be unrealizable in real life (size, power handling, standard values, Q, operational frequency, etc.), or maybe you have a box full of parts you want to use and the suggested value is not readily available. In those instances and others, being able to grab a handy-dandy design chart to see where component values lie with respect to all design parameters. In this 1963 Electronics World magazine article, author A.L. Teubner describes the process for using his ripple filter graph and provides an example...

Google Supercomputer Accessed Parallel Universe

"Google's quantum computing breakthrough on Monday has left the physicist who heads the project a believer in 'the idea that we live in a multiverse.' 'Willow,' the tech giant's new quantum chip, succeeded in solving a computational problem so complex it would have taken today's best super-computers an estimated 10 septillion years to solve it - vastly more than the age of our entire universe. But Google said its new quantum computer solved the puzzle 'in under five minutes.' Calling Willow's performance 'astonishing,' the leader and founder of Google Quantum AI team, physicist Hartmut Neven, said its high-speed result 'lends credence to the notion that quantum computation occurs..."

Crossword Puzzle from Electronics World Magazine

Crossword puzzles have probably lost their appeal to most people - especially if they are on paper and not in electronic format that can be worked on a computer (your smartphone is also a computer, BTW). I suspect so because up until early this year, I created a custom electronics-themed crossword puzzle every week for RF Cafe visitors, but not a single person has written to ask that they be continued. Oh well, that saves an hour every Sunday. Lots of magazines used to print crossword puzzles based on their readers' interests. Unlike the RF Cafe crosswords that use only relevant words, those puzzles used common filler words where it was too hard to find a thematic word. This crossword puzzle from a 1965 edition of Electronics World...

ChatGPT Top 10 Topic Lists

Over the last year, I have been interacting with ChatGPT AI engine quite a bit, in order to ascertain its usefulness and trustworthiness. A mix of response quality has been received, but most inaccuracies on the part of Chat GPT have been due to imprecise queries on my part. The key to success is concisely forming your query, including detailed requirements about the output if required. My latest query prompted ChatGPT for Top 10 lists for typical user on various topics. Here are the results...

Computer Core Memories Still Handmade

According to this 1972 article in Popular Electronics magazine, there were as many as 50,000 computers in the world at the time using magnetic core memories. Among them was the Apollo Guidance Computer that was onboard the Apollo 11 Lunar Module that Neil Armstrong used in July 1969 to land on the moon. Semiconductor memories were being manufactured in 1972, but believe it or not they were not as fast as the magnetic core memories. Machinery was not available with enough precision and repeatability to thread the read, write, sense, and inhibit wires through each ferrite core. The TPX-42 IFF secondary radar I worked on in the USAF had a 1 kByte magnetic core memory. Small women with small hands were...

Television in Space

A mere five years elapsed from the time Echo, a gas-filled metallized plastic sphere that passively reflected radio signals back to Earth, was launched and the time that 35 television cameras had been launched into space. The Space Race was at a fever pitch. Although the Ruskies beat us in being the first to launch both an active satellite (Sputnik) and a man (Yuri Gagarin) into space, America's deep pool of intellectual resources, consisting of both native scientists and many of the world's top scientists who chose to flourish in freedom here rather than oppression behind the Iron Curtain, fostered the advantage that in short order established the United States as the leading super power both in space and on terra firma. TIROS satellites began providing real-time visual data on the Earth's weather in 1960. Not only were cameras transmitting images of the Earth...

The Christmas Equation

An RF Cafe visitor sent this equation to me a few years ago. It can be found all over the Internet (including here), but I cannot determine a definite origin. Mathematicians claim that math can explain everything in the universe, which is not quite true. It can't for example, explain why my next-door neighbor is a junk hoarder. This Christmas equation does not appear to begin with a particular application; it looks like something from a set of textbook end-of-chapter problems. Even if you don't celebrate Christmas, it provides a secondary benefit by demonstrating rules for the manipulation of logarithms and exponents along with basic algebraic rearrangements of terms...

Hershel Radio Company

At the end of World War II, the United States government demonstrated an appreciation for the extreme sacrifices made by its citizens by making surplus materiel available for purchase at very low cost. Companies sprang up as distributors after bidding on and buying large lots of items at auctions. Herschel Radio Company was one of many. This 2-page advertisement on a 1948 issue of Radio-Craft magazine is typical of what was seen in all sorts of technology publications in the late 1940s. A complete Fairchild model SCR 269/F airborne radio compass was offered at a mere $75 ($998 in 2024 money). A Hallicrafters model SX-28...

*Can We Ever Go to the Stars?

When I read this account of relativistic space travel by Dr. Wernher von Braun in a 1963 issue of Popular Science magazine, I was a bit dubious about numbers he presented because they seemed to me to assume a fixed value of relativistic speed during the entire round trip. It is an example of the Twin Paradox. Time dilation, as predicted by Einstein's theory of Special Relativity, is barely noticeable at 10% the speed of light (0.1c), and is not really significantly noticeable until around 30% the speed of light (0.3c), so I suspected that maybe he had simplified the answer. His space ship example reached that speed at 3½ months with a steady 1 G acceleration rate. Not wanting to go to the effort of figuring it out for myself, I asked ChatGPT 4.0 to assess the article and render an opinion...

Jensen Christmas Radio Advertisement

Seeing an advertisement like this from a national corporation - especially one that did work for the government - in a major magazine would be rare these days. In 1945 when this Christmas advertisement was proffered by Jensen Radio Manufacturing Company in Radio News magazine, it was meant as an inoffensive message of thanks and goodwill to all people, and particularly to servicemen who had just fought a difficult and sacrificial war. Fortunately, World War II would be over before the next Christmas came around. Today, some would like to prosecute the purveyor for the crime of "hate speech," which is basically anything suggesting America's founding was fundamentally righteous and just. "Merry Christmas to all, and to all a good night!..."

*Twin Paradox of Special Relativity

The Twin Paradox is a central thought experiment in Einstein's theory of Special Relativity, vividly illustrating the phenomenon of time dilation. It involves a scenario where one of two identical twins undertakes a journey into space at relativistic speeds (approaching the speed of light), while the other remains on Earth. Upon reuniting, the traveling twin is observed to have aged less than the twin who stayed behind. This effect is not merely a theoretical curiosity but a real consequence of the laws governing time and space. At the heart of the Twin Paradox is the relativistic principle that time flows differently depending on an observer's frame of reference. When objects move close to the speed of light, their passage through...

 

 

 

 

 

 

Semiconductor Trends for 2025

Here are eight predictions for the semiconductor industry in 2025, per the IDC (International Data Corporation). "1: Memory is expected to grow by more than 24%, mainly driven by the increasing penetration of high-end products such as HBM3 and HBM3e with HBM4 expected to be introduced in H2. Non-memory is expected to grow 13%, driven by demand for advanced node ICs for AI servers, high-end mobile phone ICs, and WiFi7. 2: Asia-Pacific IC design market will grow 15% as inventory levels stabilize, personal devices demand picks up, and AI computing extends to a wide range of applications. 3: Under the traditional Foundry 1.0 definition..."

Knitted Radio-Frequency Antenna Blanket

The inventors should look into selling knitted "tinfoil hats" using this technique! "Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable garment - a sweater or a blanket that is ultralight, portable, easy to fold up and stow away. Not having to use heavy, bulky satellite antennas would make communications much easier for those who live or travel in remote locations - a lightweight, flexible antenna that can send information over long distances would be a useful tool for both the public and private sectors. A Columbia Engineering team reports that they have used their expertise in metasurfaces...

World's 1st Level 4 Autonomous Network History

"Tsinghua University in Beijing began operating its network in autonomous mode, also known as 'Level 4 network autonomy,' in September this year, I have confirmed. It's an impressive achievement. But reader, I come bearing a second bulletin of autonomous network news - and this one will cause a sharp intake of breath among Western comms vendors, service providers and governments. China Mobile recently completed successful trials of Level 4 autonomous networking in Guangdong province (population: 122 million) and will begin its three-year program to deploy it nationwide in 2025. This is beyond big - it is momentous. For perspective, Tsinghua University operates a not-for-profit 16,00..."

Art of Failure Analysis 2024

"When your car breaks down, you take it to the mechanic. When a computer chip fails, engineers go to the failure-analysis team. It's their job to diagnose what went wrong and work to make sure it doesn't in the future. The International Symposium on the Physical and Failure Analysis of Integrated Circuits (IPFA) is a yearly conference in Asia attended by failure-analysis engineers. The gathering is mostly technical, but there's also a fun part: The Art of Failure Analysis contest. 'It's all about creativity and strong imagination,' says Willie Yeoh, chair of the Art of Failure Analysis..."

Ancient Wireless Blamed for UK Rail Disruptions

"The aging radio system used by train drivers and signallers across the United Kingdom is the cause of a major disruption for rail commuters nationwide Friday - another sign of the UK's failing infrastructure. Services out of major transport hubs in London, Manchester and Southampton were affected, the BBC said. Trains to and from London's major airports were roiled by delays. Great Northern, ScotRail, Southern and many other lines were also impacted. National Rail blamed the delays on a failure of its specialized GSM-R rail communications system, which is based on the 2G..."

Freelance Engineering 101

"Being an engineer in today's world is a very rewarding career experience, providing a number of benefits and incentives for those employed full-time for a single company. The advantages are usually in line with long-term career development, access to resources, and financial stability. Having such a career eliminates the stress associated with constantly looking for new projects and clients, and most reputable companies allow for access to the latest tools, equipment, and software that may not be affordable anywhere else. Of course, salary is the biggest draw when working at a single company. Our recently conducted salary and career survey paints some pretty interesting numbers when it comes to engineering trends. Those working in full-time positions have decreased when compared to last year..."
