2 Halos Stacked for 2 Meters

2 Halos Stacked for 2 Meters, January 1965 Popular Electronics - RF CafeThe stacked halo antenna is a compact configuration for obtaining a nearly omnidirectional radiation pattern with nearly 8 dB of gain. An ideal half-wave dipole antenna provides 2.15 dB, so adding 5 to 6 more decibels by merely stacking two halo antennas (which are essentially curved half-waves) might seem like getting more than the sum of the parts. That extra gain is obtained by concentrating the vertical radiation pattern lower to the horizon as compared to a straight half-wave, even though the horizontal pattern loses a bit of gain contribution from the translation to a nearly omnidirectional nature. There is nowadays a plethora of information available on the Internet regarding stacked halo antennas, but in 1965, this Popular Electronics article ...

Unique Spin-Orbit Interactions Discovered in Silicon

Unique Spin-Orbit Interactions Discovered in Silicon - RF Cafe"Researchers from from Purdue University, the Technological University of Delft, Netherlands and the University of Wisconsin-Madison have discovered that silicon has unique spin-orbit interactions that can enable the manipulation of qubits using electric fields, without the need for any artificial agents. 'Qubits encoded in the spins of electrons are especially long-lived in silicon, but they are difficult to control by electric fields. Spin-orbit interaction is an important knob for the design of qubits that was thought to be small in this material, traditionally,' says Rajib Rahman, research assistant professor in Purdue's School of Electrical and Computer Engineering ..."

Resuscitation for Electric Shock

Resuscitation for Electric Shock, December 1959 Electronics World - RF CafeElectric shock, depending on severity, can range in damage from mere discomfort to body organ damage to instant death. If you have experience an electric shock, you know that avoiding another incident is top priority when working around high voltages. My worse electric shock was either the time when I got hit with a 3-phase 440 VAC supply on an industrial air compressor motor, or the B+ vacuum tube plate supply on the air traffic control radar systems I worked on in the USAF. Both were, thankfully, from finger to finger or finger to forearm (no vital organs in the current path). I've been zapped a few other times, but nothing severe enough to require being resuscitated. Neither have I ever witnessed anyone else being shocked to the point of needing resuscitation. There are probably some gruesome ...

10 Ways X-Ray Can Help Identify Counterfeit Parts - RF CafeSlideshow: "Lead times on components of all types, from passives to semiconductors, are stretching out with no end in sight. As OEMs scramble to get the parts they need, they are increasingly likely to turn to less reliable sources, providing an opportunity for counterfeiters. 'Shortages go in cycles,' said Robin Gray, chief counsel of the Electronic Component Industry Association (ECIA). 'For years, it was tantalum capacitors but not its many types of passives, including multilayer ceramic capacitors (MLCCs), as well as certain semiconductors. A key takeaway is that when times ..."

Recent Developments in Electronics

Recent Developments in Electronics, March 1960 Electronics World - RF CafeAs one born in 1958, it's hard to accept that 1960 news is nearly six decades old. I still find myself thinking of the 1970s and 80s as just a few years ago. The first integrated semiconductor circuits were still being developed in corporate and university laboratories in 1960. Fairchild announced a year after this Electronics World article appeared their first commercial IC series, named "Micrologic." Until then, an integrated circuit meant something like the compact module of interconnected ceramic substrates with printed thick film resistors and miniature discrete components. In other news, Raytheon was ready to deploy their giant ICBM tracking radar system to deal with the emerging global nuclear war threat ...

"Line-Cord" Antennas: Fact and Fiction

"Line-Cord" Antennas: Fact and Fiction, March 1960 Electronics World - RF CafeDo you have an FM radio in your cellphone? If so, its antenna is the headphone or ear bud wires. You can buy an external FM antenna that plus into the headphone jack. Do you remember the type of line cord antenna described here? It was actually not a bad idea in many situations. Although the appliance might look a bit scary, there is no direct physical contact between the antenna wires and the house AC supply. Either a capacitor with low impedance in the radio and/or television band was connected to the plug blade or a capacitively coupled plate was placed around the AC wires to pick up signals. 60 (or 50) cycle content on the antenna would be minimal and rejected by the receiver front end filtering. Many of the problems people had with this or any twin-lead transmission cable were due ...

Crosley 03CB Vintage Console Radio for Sale on eBay

Crosley 03CB Vintage Console Radio - RF CafeEvery couple years a Crosley 03CB console radio shows up on eBay. I keep a Saved Search to get an e-mail when one becomes available, mainly to get an idea of how many are still around. My research based on Newspaper.com issues of old newspaper advertisements indicates the Crosley 03CB models were primarily sold in the PA, NJ, NY, DE, CT, OH, and MD areas. Per the eBay listing: "Working condition, lights up and plays some stations. Need some refinishing on the cabinet." If you are looking for a restoration project, this would be a good subject for only $50. As can be seen from my restored Crosley 03CB radio, the cabinet and electronics are very robust and attractive. It's worth a look ...

New Laser Makes Silicon "Sing"

New Laser Makes Silicon "Sing" - RF Cafe"Yale scientists have created a new type of silicon laser that uses sounds waves to amplify light. A study about the discovery appears June 8 in the online edition of the journal Science. In recent years, there has been increasing interest in translating optical technologies - such as fiber optics and free-space lasers - into tiny optical or 'photonic' integrated circuits. Using light rather than electricity for integrated circuits permits sending and processing information at speeds that would be impossible with conventional electronics. Researchers say silicon photonics - optical circuits based on silicon chips - are one of the leading platforms for such technologies, thanks to their compatibility ..."

Know Your Electronic Chemicals - Part 2

Know Your Electronic Chemicals Part 2, March 1960 Electronics World - RF CafeIn my nearly 60 years of building model aircraft, cars, boats, and rockets, working on cars, maintaining houses and yards, working with electrical and electronic apparati[sic], and many other activities, I have inhaled and had skin contact with many types of chemicals (all legal, BTW). You probably have, too, if you are near my age. At least by the 1960s the public was becoming aware of the dangers of exposure to common household and workplace substances, but viewing older pictures and films showing people working with no eye, ear, or skin protection explains the all-too-common common sight of crippled and disfigured people back in the days. In the early and mid 1970s I worked regularly with MEK until it was removed due to being labeled as a suspected carcinogen ...

Math Logic Puzzles from the 1961 Old Farmer's Almanac

Math Logic Puzzles from the 1961 Old Farmer's Almanac (Kirt's Cogitation #304) - RF CafeFarmers must be a lot smarter than we tend to give them credit for being. These math and logic puzzles that appeared in the 1961 Old Farmer's Almanac are not a duffer's task to complete. Be careful to consider units of measure based on the venues. Puzzle I is a relatively simple trigonometry problem, although the wording of the problem statement is very confusing; it took some head scratching to figure out what was meant. Puzzle III required me to opt for a graphical solution since I could not come up with enough independent equations for the number of unknowns. If you look at the OFA page scan ...
