New for 2021! RF & Electronics Symbols for Office™ r2

RF & Electronics Schematic & Block Diagram Symbols for Office™ r2 - RF CafeIt 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!

Vintage Heathkit DG-140 Two-Station Intercom Kit

Vintage Heathkit DG-140 Two-Station Intercom Kit - RF Cafe Cool ProductOccasionally an unbuilt vintage Heathkit item appears on eBay with really nice photos of the contents. In fact, I have a Saved Search that sends me an e-mail whenever one shows up. This morning, a Heathkit DG−140 Two-Station Intercom kit appeared on auction. The instruction booklet has a publish date of 1972, so I looked for a copy of it on the WWW but the only thing I could find was a PDF for purchase. Despite the 1972 date, it appears it was 1973 when the DG−140 was first available. The 1971 catalog still shows the previous version, the DG−141 (which you might understandably think would be the newer model number). There is a big difference in the chassis configuration from the DG−141 to the DG−140. Per the 1973 Heathkit catalog, the DG−140 was priced at $29.95 ($184.91 in 2021 money - a whopping 6.2x factor in 48 years). Heathkit products were well known for the completeness of its instruction manuals, with clearly illustrated instructions...

Micro-Doppler Radars Predict Injury Risk

Micro-Doppler Radars Predict Injury Risk and Track Recovery Progress - RF Cafe"According to researchers at Penn State, micro-doppler radars could soon be used in clinical settings to predict injury risk and track recovery progress. Being able to view subtle differences in the human movement would allow health care workers to more accurately identify individuals who may be at risk for injury and to track progress precisely while individuals are recovering from an injury. To find an accurate, reliable, and cost-effective way to measure these subtleties in human movement, the College of Engineering and College of Medicine researchers teamed up to develop radar in front of which athlete study-subjects could jump. 'My students and I designed and constructed the radar system to characterize the micro-Doppler features of human gait..."


Electroluminescence, November 1961 Popular Electronics - RF CafeWebster's dictionary defines luminescence as, "the low-temperature emission of light produced especially by physiological processes (as in the firefly), by chemical action, by friction, or by electrical action." Per this article on electroluminescence in the November 1961 edition of Popular Electronics, Webster defined it back then as, "any emission of light not ascribable directly to incandescence, and therefore occurring at low temperatures." Interesting that the contrast to incandescence is no longer used. Maybe in 1960 the phenomenon of electroluminescence was still new and novel enough to emphasize the distinction. Barely a decade had passed since it had moved out of the laboratory and into the marketplace. The ability to economically produce large panels for lighting was deemed groundbreaking...

Montgomery Ward Radio Catalog

Montgomery Ward Radio Catalog, February 1939 Radio News - RF CafeNot long ago I posted a short bit on the 1924 Montgomery Ward Radio Catalog I found on the WWW. It was the only version of the actual catalog I could find. An advertisement for this 1939 edition of the Montgomery Ward Radio Catalog appeared in a copy of Radio News magazine. Like the earlier catalog, this one appeals to both professional servicemen and amateur radio hobbyists - often one and the same. Mail order and brick and mortar outlets like Radio Shack and Lafayette Radio Electronics (where I used to buy stuff in the 1970s) had not come to most of America's towns yet, so electronics enthusiasts often procured their parts from Sears Roebuck, Montgomery Ward, and specialty catalogs or from hardware and drug stores that happened to stock components. Of course you could always walk into the local electronics repair shop...

Plastic Polymer Cables That Rival Fiber Optics

Plastic Polymer Cables That Rival Fiber Optics - RF Cafe"How fast does data flow? The answer: not fast enough. The search for more efficient data-transfer solutions to meet the ever-increasing demand for computation never ends. Even today, most data transmission happens via traditional copper cables, which are power-hungry, leading to a compromise between data exchange and energy consumed. Fiber-optic cables are an alternative, but they don't work well with the silicon chips in our computing systems. Overcoming these limitations, while theoretically possible, can turn out to be prohibitively expensive, especially for electronics-rich applications like data centers, spacecraft, electric vehicles and so on. A team of scientists at the Massachusetts Institute of Technology have recently demonstrated a plastic polymer cable that is a complementary solution..."

Explain Radio Fading to the Public

Explain Radio Fading to the Public, September 1942 Radio Retailing Today - RF CafeThis is a great primer for anyone looking for an easily understandable way to explain the basics of radio signal fading to acquaintances, or for that matter to understand it yourself if you don't already. As I review the material for taking my amateur radio General Class exam, there is information about atmospheric absorption in the various ionospheric layers during daytime and nighttime. Prior to studying the manual, I either never knew or once knew but have forgotten about the upper F1 and F2 layers combining into a single layer at night when the sun's radiation and particle bombardment is blocked by the earth. This article doesn't go that deep into the physics, but it does a good job of making a complex topic simple enough for the layman - although if you're trying to explain fading to politicians, well, don't even bother...

Attention Laser Lovers

RCA Helium-Selenium Laser (Zachary Fox) - RF CafeRF Cafe visitor Zachary Fox sent me a note regarding the "Basic Laser Experiments" article from the June 1971 issue of Radio-Electronics magazine. Mr. Fox is an avid laser experimenter / hobbyist who has a blog on the Laser Pointer Forum website where he documents his activities. He recently purchased a document containing the actual photograph shown in the article that shows RCA Solid State Research Laboratory scientist Dr. Karl G. Hernqvist projecting the 24 spectral lines of a helium-selenium laser onto his hand. What was a big deal in 1971 is ho−hum technology today, just like what is ground−breaking today will be ho−hum in 50 years. We should be grateful for people like Zachary who collect and preserve these parts of history so that someone with no interest doesn't throw it out with the trash...

A Radio Controlled Model Airplane

A Radio Controlled Model Airplane, February 1939 Radio News - RF CafeMost people familiar with the history of radio control (R/C) airplanes credit twin brothers Walt and Bill Good for the first truly successful R/C airplane, which they dubbed "Big Guff," in 1938. Interestingly, this YouTube interview with the Good brothers mentions, as does Mr. Isberg in his 1939 article in Radio News magazine article, the first sanctioned R/C contest where the Good's model was the only one to fly. Ross Hull and Clinton DeSoto were two other prominent early R/C'ers. Transmitter operators were licensed Hams who designed and built their own equipment at 56 MHz, unlike modern turn-key R/C systems operating in unlicensed ISM bands. Vacuum tubes were used in the transmitter and the airborne receiver. Lead-acid batteries often provided power for the receiver and control surface actuators (pseudo-servos) in the airplane, which unfortunately would burst during a crash...

RF Noise Problems Vary, Remedies Elusive

RF Noise Problems Vary, Remedies Elusive - RF Cafe"RF noise is a frequent discussion topic among radio amateurs. A proliferation of electronics has cluttered and complicated the noise environment; it's not just power lines anymore. Unless isolated from civilization, most hams experience RF interference (RFI) - sometimes without even realizing it, although spectrum scopes on modern transceivers make RF noise much more apparent. Various approaches to address the apparently worsening noise floor have been taken around the world, some addressing lax regulation. 'We all want to enhance our ability to copy the weak ones by increasing our signal-to-noise ratio,' Alan Higbie, K0AV, said in his March/April NCJ article, 'Tracking RFI with an SDR One Source at a Time..."

Lost Your Money? Wire KUBIT

Lost Your Money? Wire KUBIT, November 6, 1948, The Saturday Evening Post - RF CafeSending telegraph messages, whether by wire or wireless means, has always been expensive, particularly considering charges are determined by the character (letter, number, symbol). Accordingly, the Shakespearean line from Hamlet declaring that "brevity is the soul of wit" can be reworked to "brevity is the soul of economy." A telegraph wire, unlike a telephone call, is a legally binding communiqué, as is of course a written letter, but a telegram is immediate transmission of information for time-critical messaging. A series of "commercial codes" were developed enabling senders to save often significant money by sending multi-character codes that represented entire phrases and/or sentences. What struck me about this article that appeared in a 1948 issue of The Saturday Evening Post is how, following a court case involving how the inadvertent swapping of two character positions in a code...

Pre-Compliance RF Testing Large Systems In-Situ

Pre-Compliance RF Testing Large Systems In-Situ - RF CafeMr. Kenneth Wyatt has a good article on the EDN website entitled, "Pre-Compliance Testing Large Systems In-Situ." He gives advice on relatively inexpensive tests you can perform on your new product design to help assure first-pass EMC compliance testing as performed by commercial services - which can be very expensive. He begins: "Last year, I had a chance to perform pre-compliance testing on a couple large systems for radiated emissions. The clients were hoping to get early test data prior to the major work of packing and transporting their large floor-standing systems for formal compliance testing. Large industrial systems need a whole different technique for assessing radiated emissions..."

Mac's Radio Service Shop: The TVI Sleuth

Mac's Radio Service Shop: The TVI Sleuth, August 1954 Radio & Television News - RF CafeTracking down the source of TVI (television interference) or any kind of RFI (radio frequency interference) can be a challenge. In the days when most people received their audio and visual entertainment (radio and TV) via over-the-air broadcasts, any form of interference was usually picked up by multiple people, who promptly reported the issue to the power company or the FCC. Arcing power lines, transformers, and switches were prime generators of RFI, particularly during wet and high wind conditions. However, much more prevalent was interference from industrial and domestic equipment. Neon and fluorescent light, heating pads (see Hazel: Stop Rockin' Our Reception episode), ignition systems (automotive and oil burners), diathermy (heat therapy popular in the day), industrial RF heating, kitchen appliances, and tool motors were among the likeliest offenders. Of course amateur radio operators were guilty of spewing out interfering EM crap...

Hybrid III-V Tunnel FETs and MOSFETs

Hybrid III-V Tunnel FETs and MOSFETs - RF Cafe"Over the past few decades, the incredible progress made in the electronics industry has been partially driven by innovations at the single-transistor level. Building faster and smaller transistors has been a primary goal for the semiconductor industry over the past few years. Metal-oxide-semiconductor field-effect transistors (MOSFETs) are the most conventional and widely used type of transistors. One of their major limitations is their high power inefficiency, which is due to their inability to reduce the voltage supply while simultaneously limiting the off-state leakage current. A novel and alternative type of device called a tunnel field-effect transistor (TFET) can overcome this limitation by leveraging quantum mechanical tunneling..."

In the Field with International Pacific Highway

In the Field with IPH, December 1931 QST - RF CafeIt is hard to imagine a time when there wasn't a vast network of highways connecting not just the interior of the continental U.S., but also interconnecting all of the countries in North America. Just as pioneers in covered wagons and on horseback forged the routes that became the Oregon Trail in the early 19th century, so did teams of explorers, cartographers and engineers do the heavy lifting in the early 20th century in establishing the first defined roads for expediting the transportation of goods and persons all up and down the continent's west coast. Radio operators were among the crews of the International Pacific Highway (IPH) project. Heavy, bulky, and fragile tube-based radio equipment was transported in vehicles equally bereft of adequate facilities in the form of power and shock absorbing suspensions. This story from a 1931 edition of the ARRL's QST magazine tells of harrowing experiences in the jungles and mountains of South America...

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
