A schematic for an Oscilloscope “Circuit Octopus”

You probably have a junk box of components, but can you identify all of them? And do you know whether they all work?

I came across a neat video prepared by amateur radio operator W2AEW, a 10-minute tutorial on checking components. The video gives an example of performing simple component testing using a curve tracer or “Circuit Octopus” and an oscilloscope.

It describes the Octopus, then delves into how to check resistors, diodes, transistors and even capacitors. When feeding an oscilloscope with the test fixture, you can identify open or shorted components. Here’s the link for the video: https://youtu.be/Gwo3pEH7hUE.

There are hundreds of schematics for building your own Octopus. Stephen M. Powell’s design, shown above, is one of the simplest.

Old law, new take
Over the years consultant Frank Hertel has contributed many useful ideas for readers of this column. Frank’s brother, Johnny, likes to delve a little deeper into electronics.

He writes that he recently came across a list of electricity definitions. Most were familiar, but three jumped out at him:

The first is 1 Ohm, which was defined as the resistance of a column of mercury (at the temperature of melting ice) of a uniform cross section of 1 square millimeter and a length of 106.30 centimeters.

One Volt is the electromotive force that produces a current of 1 Ampere when steadily applied to a conductor with the resistance of 1 Ohm.

One Ampere is the unit of current strength. It is the current which, when passed through a solution of nitrate of silver in water (in accordance with certain specifications), deposits silver at the rate of 0.00118 of a gram per second. The flow of electrical current is measured in Amperes or Amps, using an Ammeter.

Kind of relates Ohm’s Law in a new way, doesn’t it?

You need a shrink
A number of years ago, 3M developed a product called Cold Shrink as a weather seal for cabling. Broadcast engineer and frequent contributor Dan Slentz called this line of cable joints and terminations to my attention and wondered why he hadn’t heard of it before now.

3M Cold Shrink pre-stretched tubes effectively seal coax connectors from weather.

When it was released, I recall that each Cold Shrink tube was pretty expensive, much more costly than other forms of connector weather-sealing. Apparently as the product has evolved, its cost has gotten more reasonable.

So what is Cold Shrink tubing? It’s an expanded tubular rubber sleeve, and 3M found a way to stretch the diameter of the tubing so it will fit over an RF connector.

[Check Out More of Workbench Here]

The sleeve is kept in its expanded state with a wound plastic core. After the sleeve is positioned over the connector to be weatherproofed, you unwind the plastic core. As the plastic core is removed, the expanded rubber begins to shrink, forming a constant radial pressure seal around the connector and cable.

An image from the 3M website shows installation of Cold Shrink for an underground cable run.

Originally designed for the power industry, Cold Shrink tubes are ideal for outside RF connections in the broadcast industry. Plus, in addition to protecting connectors, Cold Shrink tubes conform to the water seal requirements of ANSI C119.1.

See the video Dan found at the website of Thorne & Derrick International at www.powerandcables.com/cold-shrink-tubes/.

3M itself has a useful info page that we’ve linked at https://tinyurl.com/rw-coldshrink.

Can you imagine trying to use a torch to heat shrink a standard weatherproofing boot up on a tower? Keep this product in mind for your next tower cable run.

He has had a “unique” path to success. Now, 2022 NAB Show attendees will get to hear all about it, as Byron Allen has agreed to appear in a flame-free “fireside chat” scheduled for Wednesday, April 27 at the Las Vegas event — the NAB’s first since 2019 due to the COVID-19 pandemic.

Allen will be interviewed by retired NAB President/CEO Gordon Smith, who now serves as a special adviser to the organization.

The discussion is on the calendar for a 9:15am Pacific start.

Allen is the President/CEO of Allen Media Group and Entertainment Studios, and has emerged as a media mogul, with broadcast TV stations just one component of his empire.

It is Smith’s goal to have Allen engage in a two-sided conversation in which both the former U.S. Senator and the TV industry star “discuss the steps in their professional careers that helped them achieve success.”

The chat will serve as the centerpiece of the NAB Show Executive Leadership Series session. Allen and Smith also plan to address their respective roles as advocates and leaders in the broadcast industry and the “enduring value” of local television in an ever-changing marketplace.

Allen Media Group owns 27 television stations in 21 markets, and could grow exponentially in the coming months and years.

Allen also partnered with Sinclair Broadcast Group in 2019 to acquire 21 Regional Sports Networks (RSNs) — a story often overlooked by national media.

Meanwhile, Allen’s Entertainment Studios, which predates the owned-station operation, produces and distributes syndicated program and sells advertising for 67 broadcast and cable television programs.

THE GORDON SMITH SHOW As previously reported, the retired U.S. Senator and former NAB head will receive NAB’s highest honor, the Distinguished Service Award, at the 2022 NAB Show.

It’s known for nationally distributed digital multicast television networks such as the popular MeTV and siblings DECADES, Start TV, Heroes & Icons and MOVIES!

Now, the family of Weigel Broadcasting‘s national broadcast networks is set to expand.

Oral arguments are set for April 12 in the broadcast industry’s lawsuit against the FCC, seeking to overturn the commission’s order mandating disclosures for foreign government-sponsored programming.

On Friday the National Association of Broadcasters, the Multicultural Media, Telecom and Internet Council and the National Association of Black Owned Broadcasters filed a reply brief with the federal appeals court. They are the organizations that brought this suit against the FCC.

They say the court should set aside the action because it violates not one but three crucial standards: the Communications Act, the First Amendment and the Administrative Procedure Act.

Among their arguments, the broadcasters say that the FCC order tells stations to engage in “reasonable diligence” to determine the true source of the programming aired on its station, which mandates independent investigation of government websites.

“But the broadcaster’s statutory duty is far narrower,” they said. “Congress required only that each broadcaster ‘shall exercise reasonable diligence to obtain from its employees, and from other persons with whom it deals directly’ information necessary to disclose to the public the person who paid for the programming.” The plaintiffs emphasized the underlined phrase, concluding: “The commission cannot ignore the restrictions Congress has placed upon a broadcaster’s duty of diligence.”

They also criticized “the regulation’s extraordinary reach and sheer pointlessness” and said mandatory investigation “redresses a phantom harm never known to occur: namely, a foreign governmental entity registered under the Foreign Agents Registration Act or a U.S.-based foreign media outlet registered under Section 722 of the Communications Act who leased broadcast time without disclosure.”

And they say the rule imposes substantial burdens on thousands of broadcasters to address the phantom harm. It said the FCC’s limited evidence — which in any event concerns no “harms” that the order redresses — can’t justify requiring every commercial broadcast station in the country to conduct independent investigations for every existing and future lease.

[Read the reply brief.]

The rule was approved 4–0 by the commissioners last year. Now, when a broadcaster leases time, they need to ask the “lessee” if they or their programming are from a foreign governmental entity.

“If the answer is yes, a sponsorship identification will need to be placed on air and documented in the station’s public file,” Chairwoman Jessica Rosenworcel wrote at the time.

“If the answer is no, a broadcaster will need to independently verify the lessee using the Foreign Agent Registration Act website from the Department of Justice and the FCC’s semi-annual foreign media outlet reports.”

The FCC believes that foreign governmental entities are increasingly purchasing time on domestic broadcast stations.

Rosenworcel said last year, “We know that foreign entities are purchasing time on broadcast stations in markets across the country, including Chinese government-sponsored programming and Russian government-sponsored programming right here in our nation’s capital.”

RCS Cloud will be another focus of the RCS booth. The company calls it a true disaster recovery cloud solution, written for and on Amazon Web Services, following best practices and securities. “RCS Cloud disaster recovery can not only back up your audio, logs, metadata, and SQL backups, securely with Zetta’s built in Site Replication service, but we’ve also incorporated business friendly workflows.”

New GSelector 5.0 got a subtle thematic facelift, the company said, with the addition of new themes, scalable icons and a user-customized Song/Link Window, allowing users to organize and hide or display metadata based on multiple layouts.

“Programmers can already view and schedule their time granularity by hours and minutes, but now, with GSelector’s Flex Clocks, users can build their clocks and grids down to the minute or a single clock up to 24 hours a day, allowing for endless programming opportunities to save time and efficiently.”

Selector2GO allows users to add or edit elements, adjust clocks, schedule and massage logs, and analyze their spins.

RCS also highlights Aquira, its CRM, sales and traffic solution; RCS News, a centralized location for reporters to monitor RSS news feeds and email accounts, customize alerts for breaking news, define sub-categories and create and edit rundowns or audio; and Revma, a content delivery network infrastructure.

The FCC has issued a ruling in a dispute over a construction permit to move a FM translator in the city’s historic Beacon Hill area.

The WGBH Education Foundation, licensee of non-commercial WGBH(FM) in Boston, in June of 2020, filed a modification application to move the existing WGBH translator (W242AA) to a new site immediately adjacent to its licensed site in the city. WGBH also proposed a non-adjacent channel change from Channel 242 to Channel 247, and explained the swap would eliminate contour overlap with first-adjacent channel full-service WSRS(FM), licensed to Worcester, Mass.

It was the request to move the WGBH FM translator channel that would begin a domino effect and bring on a flurry of FCC filings by several other radio groups.

To start the FCC’s Media Bureau granted the WGBH modification request on June 24, 2020. The next day Beanpot License Corp., which owns WXRV(FM) at 92.5 MHz in Andover Mass., filed a request with the FCC to modify the facilities of its FM translator station Channel W243DC in Needham, Mass., to take advantage of the vacated WGBH channel on Chanel 242.

Then WJFD-FM Inc., licensee of full-service WJFD(FM) in New Bedford, Mass., in July 2020, filed a petition for reconsideration of the WGBH translator modification CP on the basis it would cause predicted interference to WJFD at 97.3 MHz.

[See Our Business and Law Page]

WGBH subsequently submitted a cancellation letter a month later to the Media Bureau stating it intended to stay put in its existing location and continue operating its translator on Chanel 242. Beanpot then objected to WGBH’s cancellation letter.

Beanpot in its argument supporting its objection to the of the WGBH translator modification cancellation cited several previous bureau decisions to support its claim that “once the FCC grants a translator modification application, the applicant must carry out the approved channel change and has at best an implied STA to continue operating on its original frequency while it constructs the new facility,” according to the Beanpot filing.

The back and forth between the parties continued with WGBH writing in its reply to the FCC “it has chosen not to change channels because information provided by WJFD has demonstrated to WGBH that it would not be practical for [the translator] to be built out on Channel 247.”

However, Beanpot continued to press the FCC to force WGBH to complete work on its new translator within the terms of its construction permit. “Beanpot disputes the validity of the predicted interference showing submitted by the WJFD application,” the broadcaster wrote.

Beanpot, which bills its WXRV(FM) as “Boston’s Independent Radio,” further argued that WGBH failed to formally serve the broadcaster with its CP cancellation letter in a timely fashion.

WGBH in Nov. 2020 attempted to resurrect its FM translator CP and move to the new site but to remain on the existing Channel 242 and at a lower power (3 watts ERP). In its second modification application, WGBH insisted its proposed transmitter facilities would not cause any prohibited contour overlap with the licensed Beanpot translator.

The NPR affiliate stated: “[The] proposed WGBH translator facilities would comply with respect to the first adjacent channel facility authorized in the Beanpot Modification Application because the area of existing overlap between the proposed WGBH Translator and the proposed Beanpot Translator would not increase as compared to the existing overlap between the licensed WGBH Translator and the proposed Beanpot Translator (in fact, would slightly decrease).”

Beanpot within a day filed an informal objection to WGBH’s second modification application.

Albert Shuldiner, chief of the FCC’s Audio Division, in a letter last week rejected Beanpot’s objections to WGBH’s cancellation letter and WGHB’s second modification application. The finding granted WGBH’s second modification application and appears to give the green light to WGBH to complete its FM translator move to the new facility site and remain on Channel 242.

It’s not clear from the FCC filings whether Beanpot License Corp. will proceed with its proposed modification request to switch FM translator channels.

Chuck Kelly has retired.

“Since the summer of 1973, all I’ve wanted to do was be involved with radio,” he wrote on LinkedIn. Forty-eight years later, he can say he met his goal.

Having worked early in his career as a jock, PD, news director and chief engineer for stations in Colorado and Illinois, Kelly moved into technology sales in 1980 by going to work for 3M, where he was sales manager of International Tapetronics for eight years.

From 1988 to 2006 he was with Broadcast Electronics, a face of the company to the international market as its director of international sales. He then went to Nautel and worked there for 13 years as director of sales and later regional sales manager for the Asia/Pacific region.

In 2019 he rejoined Broadcast Electronics, which was under the new ownership of Elenos Group, as vice president of market development. His last day was Friday.

Kelly also is a longtime member of the Society of Broadcast Engineers and was its president for two terms.

“Thank you to the folks who worked beside me and had endless patience with my mistakes as well as my enthusiasm,” Kelly wrote on LinkedIn. Thank you to the customers, business partners and friends from more than 120 countries in every corner of the world, I can never forget you.”

“While I won’t be working 8 to 5 anymore, I have several consulting gigs lined up to stay busy, and will hopefully continue my association with SBE Chapter 25 here in Indianapolis, as well as with the Holy Spirit at Geist 9:30 a.m. choir,” he wrote. “And I plan to fire up W9MDO on HF and DMR from time to time. I hope to catch you down the log.”
