They Don’t Call Capacitors “Old Sparky” for Nuthin’

Radio World - Wed, 12/04/2019 - 10:58

We’ve written about electrolytic capacitors lately. I found a funny video of what happens when you mistakenly connect the “+” voltage to the negative terminal of an electrolytic in a simple flasher circuit. Take a look online at https://tinyurl.com/rw-work-cap (and don’t try it at home).

No identities of where this submission originated. After all, we’ve all probably experienced this or seen it happen to someone not respecting that “+” symbol.

While we’re on the subject of capacitor education, have you heard of ultra-capacitors? A brief tutorial explains the ultra-capacitor and its ability to store tremendous amounts of energy. Watch it at https://tinyurl.com/rw-work-cap2.

Also discussed is ESR, Equivalent Series Resistance, which we’ve covered in this column. ESR is a small internal resistance that limits current. In the case of the ultra-capacitor, the ESR is an amazingly low 7 milli-ohms! This means the ultra-capacitor can discharge hundreds of amps.

Capacitors of this size are used to dump hundreds of amps quickly; one application is handling the sudden stops and starts in electric cars. In the experiments in the video, you can see them used to vaporize bits of metal and circuit board traces. These are powerful components, not to be played with, as you will see. In addition to explaining some capacitor theory, the video demonstrates how dangerous innocuous components like capacitors can be.

Paul Sagi writes from Malaysia that the company SDRplay has released a software update that allows you to scan a wide swath of bandwidth using a software-defined radio. For those new to this technology, SDRs replace traditional components like mixers, filters and amplifiers inside a receiver using software on a personal computer to replicate those component effects.  

This new software permits rapidly scanning in 10 MHz (or less) chunks over the SDRplay’s frequency range. It’s a software-defined spectrum analyzer! See www.rtl-sdr.com/tag/spectrum-analyzer-2 for more info.

Paul writes that years ago he had equipment on the bench and physically adjusted tuned circuits. Now that function is all handled in software, which makes sense; tuning a filter simply changes the mathematical function of the filter, and computers now have the capability to perform the math quickly enough.

**** Fig. 1: Home Depot has a clamp assortment every engineer can use.

My Telos colleague (and SBE board member) Kirk Harnack found a virtual bonanza for engineers at Home Depot! It’s a 22-piece reinforced spring clamp set, made out of fiberglass nylon. The best part? The set costs less than $10 for 22 clamps! These aren’t cheap clamps, either. They have non-slip grip handles and vinyl tips to protect the work they are gripping. 

At homedepot.com, enter 302755768 in the search field to find this.

Readers who have seen my Workbench presentations for the SBE may remember using the spring clip on a clipboard to hold components while soldering. With the variety of sizes in this set, there’s a clamp for any size job.

You know how important it is to conserve your resources, even if it’s cool air. Kevin Wagner is the operations director for Eagle Communications in St. Joseph, Mo. Not long ago, Kevin invested in a new, smaller transmitter, and the upgrade left him with a large empty room.

Fig. 2: Plastic flaps contain the cool air at a transmitter site.

The snag was that he was now cooling all that empty space. He needed an inexpensive means to reduce the size of the conditioned area. Sure, he could have built a wall, but what if a future tower lessee required the empty space to be cooled again? Fig. 2 show’s Kevin’s solution.  

You see these plastic flaps used in refrigerated storage areas in supermarkets; they keep the cool air contained, but the overlapping flaps can be parted to permit entry into the cooled area. Plus, the fact that the plastic flaps are clear, you can see if someone enters the building while you are working.  

These freezer curtain strip sets run between $80 and $200, depending on your size requirements. Search “freezer curtain strips” on Amazon or Google.

Readers enjoyed the EAS loop antenna project we told you about from Ken Beckwith, EMF field engineer. Several readers have inquired about the physics behind the wiring method used; Ken has been gracious enough to explain. 

The question dealt with grounding the shield of the conductors. In Ken’s design, the shield on the wiring is the primary of a transformer that actually receives the AM signal. The wire conductors form the secondary of the transformer, and provide the signal to the RF connector going to the receiver. If the shield was not grounded, there would be no voltage generated in the loop. 

Not everyone knows all the tricks and tips you’ve used for years. Share your ideas in the pages of Workbench — help other engineers while you qualify for SBE recertification credit. Send tips and high-resolution photos to johnpbisset@gmail.com.

DAB+ Development Resumes in Poland

Radio World - Wed, 12/04/2019 - 08:46

The author is project directory for WorldDAB.

Bernie O’Neill

Today, there are more than 25 DAB+ audio services available to listeners in Poland, eight of which are exclusively available on DAB+ digital radio. That said, much of the radio landscape in the country has remained unchanged, and despite a number of stations launching on DAB+ in recent years, the geographical share of DAB+ in the country is the same as it was when it first launched just under five years ago.

However, as confirmed by KRRiT [the National Broadcasting Council of Poland] at the WorldDAB General Assembly 2019 at the start of November, all this is about to change as Poland prepares to resume the development of its DAB+ network over the next few years.

Poland’s (national and regional) public broadcasters are currently operating the only multiplex in the country, but as revealed at WorldDAB’s flagship event in Brussels earlier this month, a new, three-step expansion plan is set to start in October 2020 and conclude in October 2022.

As part of this plan, which for the most part will focus on highways and other main roads, population coverage is set to reach 68.2% by the end of the first, 77% by October 2021 and over 81% by the end of the third phase, in October 2022.

Speaking at the General Assembly, KRRiT strategy expert Krystyna Kuhn touched on KRRiT’s five-year regulatory strategy for the period leading up to 2022, pointing to the growth of DAB+ and the launch of two new multiplexes as one of the key priorities for the National Broadcasting Council of Poland.

DAB+ digital radio first launched in Poland in 2013, with two transmitters going into operation in Warsaw and Katowice — two the most populated agglomerations in Poland — and covering over 17% of population.

In October 2015, Poland’s DAB+ network included 24 transmitters in 17 locations across the country, covering over half (55.5%) of Poland’s population and a third of its territory, and it now seems the Polish radio industry is ready to take another step forward towards digitisation.

November also saw the first licences for regular transmissions on local multiplexes being granted for the cities of Warsaw, Katowice, Poznań, Rzeszów, Częstochowa, Toruń and Tarnów.

And despite an apparent lack of DAB+ marketing campaigns, the new international DAB+ logo is increasingly being used by key stakeholders in Poland, while the number of receiver sold in the country continues to grow — there are now over 100.000 DAB+ receivers in the market, excluding devices sold over the internet.

Podcast #222 – Marking the 20th Anniversary of Indymedia

Radio Survivor - Tue, 12/03/2019 - 23:49

November 30 was the 20th anniversary of the “Battle of Seattle” protests against the World Trade Organization ministerial meetings in that Pacific Northwest city. The broad array of groups and 80,000 people who assembled understood they would not receive a fair hearing in the mainstream press, so they built their own internet-based platform to instantly publish accounts from the street in words, sound, pictures and video. They called it Indymedia, sparking a citizen-journalism movement that quickly went worldwide before the invention of YouTube, Facebook or Twitter.

To mark this anniversary we return to our conversation with Slate journalist April Glaser, who was active in the Indymedia movement and low-power FM. Earlier this year April wrote a piece for Logic Magazine called, “Another Network is Possible,” observing how the path of what we now call “social media” is just one possible outcome, and that Indymedia was another possibility. That said, we discuss how the innovation and spirit of the movement lives on today.

Broadcasters Foundation Gets in Giving Spirit

Radio World - Tue, 12/03/2019 - 14:15

Dec. 3 is Giving Tuesday, and the Broadcasters Foundation of America wants radio and TV people to get in the holiday spirit.

Today, the foundation is launching its year-end campaign for donations to support its mission to “provide an anonymous safety net” for broadcasters and their families in times of need. 

This year, the 501(c)3 charity says it will grant at least $1.3 million in aid. This represents a sharp uptake in giving; since 2000, the BFA has given out about $11 million, and the association says the number of monthly grants it awards have “increased over 75% since 2015,” according to a press release. For example, in 2000 the foundation gave $61,000 to those in need, compared to $802,800 in 2016. Additionally, the BFA says it has awarded more than 500 emergency grants since 2015.

“Requests for assistance have escalated at an alarming rate over the past several years,” Broadcasters Foundation President Jim Thompson said in the announcement. “At this giving time of year, we ask every broadcaster to give thanks for their success and good fortune with a tax-deductible contribution that will help us continue our mission of providing aid to those in our business who need it most.”

The foundation requests tax-deductible personal donations be made out to the Guardian Fund and corporate contributions to the Angel Initiative. Bequests can also be made through the foundation’s Legacy Society.

SBE President and Other Colleagues Memorialize John Lyons

Radio World - Tue, 12/03/2019 - 14:08

Colleagues are remembering engineer John Lyons this week; and his memorial service details are now available.

As Radio World reported earlier, Lyons died unexpectedly Friday. In response to the news, Society of Broadcast Engineers President Wayne Pecena released a statement, calling him “a bigger-than-life icon of the broadcast engineering community in New York City.” Pecena said that Lyons’ “handprints were on all major New York City broadcast and communications facilities from Empire State to 4 Times Square.” 

The SBE Education Summit held Sept. 28, 2016, at OWTC. John Lyons is in the front row left.

Lyons’ most recent and ambitious project was the design and buildout of Durst Corp.’s broadcast facilities at One World Trade Center. In 2016, prior to OWTC’s completion, Pecena remembered, the site hosted the SBE Education Summit, during which Lyons gave attendees a tour, which Pecena says was a special occasion and now a memory “to be cherished.”

Lyons was a longtime member of the SBE. Pecena noted that Lyons had served on the board of directors for four years and subsequently was elected a Fellow. Lyons and Pecena also shared the distinction of the Radio World Excellence in Engineering award; Lyons was named the third recipient in 2006, and Pecena joined the ranks in 2014, upon which occasion, Pecena recalls, “When I received that award, his email to me simply stated, ‘Congratulations to #11 from #3.’”

 [John Lyons Dies; Helped Shape New York’s RF Skyline]

In response to a Radio World invitation, other colleagues have sent thoughts.

Warren Dyckman remembered Lyons as a friend and client of Hanson Broadcast Engineering for the fitout of the 1 WTC 90th floor and master antenna system. “John was always a great manager and always made time to facilitate and build and support not only on the work site but also on the teams bringing the technology and the broadcast clients to 1 WTC.”

Another colleague recalled his addition to trains. “He was a devout rail fan and took the train whenever he could,” said Richard Ross of Univision Communications. “I met him in the dining car of the Lake Shore Limited on route to Chicago some years back and he greeted with a usual insult ‘I didn’t know they let bums like you on the train,’ which reassured  me all was well.”

Clay Freinwald remembered Lyons for his “wry humor and gracious ways.” Colleague Josh Gordon called Lyons “quick witted, incredibly funny and one of the best organized people I have ever known. I never understood how he could manage so many people, tasks and details and still have time to respond personally to small requests for details and decisions in near real time. He was a giant in our industry, yet very humble.” 

[Lyons Takes Helm at AFCCE]

Consultant Paul Shulins recalled “a real family man who was always full of energy and ideas. He spent countless volunteer hours running AFCCE meetings and working as the treasurer of that organization. He also helped so many fellow engineers as a mentor and advisor. We will miss you, John. When I look at the New York City skyline I will always think of you. There is no better honor.”

Fellow broadcasters and friends are invited to share their memories at DignityMemorial.com. That obituary page includes information about a visitation scheduled for Thursday Dec. 5 from 2 to 6 p.m. at Chas. Peter Nagel Funeral Directors in New York. His funeral is scheduled for Dec. 6, 11–11:45 a.m. and will be held at Maple Grove Cemetery, according to the website.
