RF Cafe Has a New Look ... with More to Come!

RF Cafe Has a New Look ... with More to Come! - RF CafeYou might have noticed a new layout for RF Cafe this morning when visiting. It is something I have been wanting to do for a long time, based on the information available from major search engine companies and the plethora of 'experts' regarding expectations and requirements for modern Web users. The term used for optimizing website structure and page content is 'Search Engine Optimization' (SEO). Many of the most highly recommended tactics have not been possible because of the fundamental structure of RF Cafe, which has been necessitated by commitments made to advertisers and by long-held preferences of my own. The time for major change has come, and it began a couple days ago ...

Notable Tech Quote: Scott Adams

Scott Adams Quote (Wikipedia pic) - RF Cafe"I think 'Dilbert' will remain popular as long as employees are frustrated and they fear the consequences of complaining too loudly. 'Dilbert' is the designated voice of discontent for the workplace. I never planned it that way. It just happened." - Scott Adams

Free Career Advancement Books & White Papers

Free Books and White Papers from NetLine (September 2014) - RF CafeTradePub is a service that offers free books (and book excerpts), magazine subscriptions and whitepapers to qualifying engineers and technical professionals. I have downloaded many over the years and find them to usually be useful. This group happens to be related to career advancement, but the topics are widely varying. I can honestly say that I cannot ever recall being placed on any kind of annoying list as a result of signing up ...

Wireless Engineering Crossword Gets 'A's

Wireless Engineering Crossword Puzzle for September 28, 2014 - RF CafeThis week's Wireless Engineering crossword puzzle's six longest words begin with the same letter. I give it a grade of 'A' for effort. As always, every word, sans none, is related to technology. Enjoy.

High Tech Comics

High Tech Comics, November 1944 Radio Craft - RF CafeA wee bit of levity in the form of comics is good for the soul on Friday, the last day of the work week... just a few more hours to go until two days of freedom. Good humor, it is said, contains a degree of truth in it, and this group from vintage editions of Radio Craft magazine is no exception. One of the comics in particular struck a chord with me - the one with the table model radio where the serviceman is speaking on the phone with his customer. The first familiar feature is the shape ...

Chart of Radio Symbols

Chart of Radio Symbols, December 1942 Radio Craft - RF CafeThis is a really nice electronic symbols chart that will come in handy for hobbyists who work with vintage electronic equipment. Not only does it have component symbols that a modern chart would not likely contain, but it has three-dimensional sketches of each device. It's too bad the chart is not in color because it would make a nice picture to frame for a decoration. If anyone with an artistic bent feels compelled to colorize it and send it to me, I'll be glad to make it available to visitors ...

Michael Dunn's Heathkit ET-3100 Experimenter

Michael Dunn (EDN photo) - RF CafeHeathkit ET-3100 Experimenter (EDN photo) - RF CafeI don't know Michael Dunn, but every time I see his picture on the EDN website it makes me think he's got to be a good guy to work with. After all, how many people post a photo of him/herself on a professional website with a soldering iron between his/her teeth? Where is OSHA when you need them? ;-)  What got my attention this time was a picture in an article titled "Electronics of Our Youth" of a Heathkit ET-3100 Experimenter like the one I had many moons ago. The function generator in mine fried twice (replaced it once) just from being overloaded with too little external circuit impedance - poor design IMHO.

Wartime Radio: The Secret Listeners

Wartime Radio: The Secret Listeners - RF CafeI have written often about the many contributions that hobbyists make to various fields of technology. Often times the efforts put out and methods used by amateurs are on par with those of professionals; the main difference between the two being that amateurs do not get paid for their work. This archived BBC video titled "Wartime Radio: The Secret Listeners," sent to me by longtime RF Cafe contributor Gary Steinhour documents how the work of two British amateur radio operators, Russell Clark and R.J.B. Hippisley, resulted in a significant strategic ...

Hands-On Introduction to LabVIEW for Engineers

Hands-On Introduction to LabVIEW for Scientists and EngineersHands-On Introduction to LabVIEW for Scientists and Engineers, by John Essick. This book provides a "learn-by-doing" approach to acquiring the computer-based skills used in daily experimental work in engineering and the sciences. Ideal as an instructional lab textbook or for self-study by individual researchers, this book is not a manual-like presentation of LabVIEW, but rather leads its readers to mastery of this powerful tool through ...

Carl & Jerry: Treachery of Judas

Carl & Jerry: Treachery of Judas, July 1961 Popular Electronics - RF CafeBut nine times out of ten when you draw a blank in analytic geometry or calculus, you'll find that your trouble is caused by weakness in algebraic manipulation." That statement is not a major factor of the plot, but it does ring true in a familiar way. I remember noting that the guys who had trouble in calculus class usually did so because they were weak in basic algebra and trigonometry. An engineering calculus class moves at such a rapid pace, with many new concepts thrown at you every day, that you absolutely must not have to learn algebra and trig concurrently ...

Fahnestock Clips - Heard of Them?

Fahnestock Clips Ad, August 1947 Radio News - RF CafeYou have probably seen Fahnestock clips, but did you know that's what they were called? Me neither, until I first saw the name of them on a page in a MicroMark catalog a while back. When I saw this ad in Radio News, it seemed like a good opportunity pass it on. You can still buy Fahnestock clips from MicroMark. Model train enthusiasts use them for wiring their layouts since they facilitate...

Sherlock Ohms: What Made the Mustang Burn Oil?

Sherlock Ohms: What Made the Mustang Burn Oil? - RF CafeBlame my soft spot for Ford Mustangs for the reason I feel compelled to promote this installment of EDN's Sherlock Ohms, even though its subject doesn't pertain to directly to electronics. Sherlock Ohms articles all focus on troubleshooting problems whether they be mechanical, electrical, or a combination thereof. In this case, the electrical problem - a computer that erroneously caused the engine to run in a lean fuel mixture mode - was caused by a mechanical problem - a clogged PCV device. It has admittedly been many years since ...
