Commissioner Brendan Carr is objecting to what he says is politically motivated pressure for the FCC to reject the sale of a Miami radio station.

Carr, a Republican, cited news reports that members of the Congressional Hispanic Caucus want the commission to reject the sale of WSUA, “Caracol 1260 AM.”

“According to the Democrat representatives, the FCC must block this change in ownership to prevent what they view as a progressive broadcast station from beginning to air conservative viewpoints to Miami’s Hispanic community,” Carr stated in a press release.

He cited quotes in Newsweek’s reporting from Florida Democrats “sounding the alarm” including a quote from Former Rep. Debbie Mucarsel-Powell that “To win in 2022 this must stop!”

[Newsweek: “Florida Democrats Sound the Alarm After ‘Spanish-Language OAN’ Buys Miami Radio Station, Fires Liberal Host”]

Carr called it an attempt by Democrats in Congress to block the sale of the Spanish-language station based on its projected political viewpoints.

“The FCC has no business doing the Democrats’ bidding or using our regulatory process to censor political opinions that Democrats do not like,” Carr wrote.

“What’s worse, the Democrats appear to be treating the FCC as merely an arm of the DNC — expressly pressuring the agency to take action that they believe will increase their electoral odds in Florida in 2022.”

He called it a “deeply troubling transgression of free speech and the FCC’s status as an independent agency” and asked his FCC colleagues to the effort.

Newsweek reported that the buyer plans to change the name of Caracol 1260 AM to América Radio.

Standard Media Index has just released its March 2021 data, and the total monthly media investment was “way up,” it reports.

In fact, it was up 22% versus March 2020, which was down 13% from a year earlier as the COVID-19 pandemic arrived on North American shores.

The gains in the last month of Q1 2021 lifted this year’s ad investment higher than pre-pandemic levels, SMI notes: March 2021 investment was up 6.3% versus March 2019.

That said, radio broadcasting executives should not get too excited, as Digital continues to lead the growth, rising 27% in March versus last year. Further exacerbating matters for the Radio industry: TV’s “very strong” March, rising 13% versus 2020.

This, SMI says, is the “first real year-over-year increase in over a year,” excluding a 1% increase in August 2020.

How to Generate Millions For Your Podcasts, Including Strategies That Do Not Include Selling Advertising

Audio search and delivery firm Audioburst now is available on the Harman Ignite Store connected vehicle platform.

Separately, Harman also opened a hub for Android Automotive developers.

“The Audioburst Android Automotive app is now available through the Harman Ignite Store to augment vehicle infotainment systems, providing drivers and passengers alike with unprecedented personalization and access to the world’s largest searchable library of talk audio content,” the companies announced.

The company’s AI listens to podcasts and radio stations, analyzes and indexes the long-form content and cuts it into short-form audio clips called bursts.

“Keywords, entities, sentiment and additional metadata features are extracted to ensure the most accurate topical segmentation,” the company explains. “The bursts are then grouped together into playlists to provide listeners with a recommended content stream based on trending topics, past behavior, and defined keywords and interests. These can be as broad as ‘Tech’ and ‘Business’ or as specific as ‘Ariana Grande,’ ‘LA Lakers,’ and ‘Pfizer stock.’”

Audioburst CEO Amir Hirsh was quoted saying this approach means drivers don’t have to browse podcasts and radio stations “in futile, and at times dangerous, attempts to find relevant content,” thanks to personalization and discovery capabilities.

Audioburst said its APIs also “provide OEMs with powerful user analytics and unique monetization opportunities.” OEMs can collect info about content consumption that can be used to inform subscriptions or advertisements.

Albert Jordan, VP of the Harman Ignite Store business unit, said the purpose of its platform is to connect drivers and passengers to their favorite apps and media.

Harman International is a subsidiary of Samsung Electronics. Samsung Venture Investment is an investor in Audioburst. Harman says 50 million cars on the road have its audio systems. Its brands include AKG, Harman Kardon, Infinity, JBL, Lexicon, Mark Levinson and Revel.

Reflecting the growing importance of the Android Automotive OS, Harman also announced a Harman Ignite Store Developers Portal, a hub for Android Automotive developers.

“Those developing to the Android Automotive open operating system can deploy automotive apps, which OEMs can then easily scale and manage to drive new digital touchpoints with their customers through the Harman Ignite Store.”

A spare transmitter blower is a great idea. Pre-wiring it is even better!

If you’ve never lost a blower motor in a high-power transmitter, your time probably is coming!

It is a helpless feeling when the transmitter completely shut down. Then add the frustration of trying to find a replacement, not to mention removing the old motor and assembly.

Honolulu contract engineer Dale Machado found a replacement blower and motor assembly to keep on hand, and added to the insurance policy by pre-wiring it. Adding the wiring harness is one less thing to think about when you are off the air.

In the case of three-phase motors, pre-wiring also reduces the chance you’ll miswire the phase, causing the motor to run backwards!

Data points

Consulting Engineer and frequent Workbench contributor Frank Hertel of Newman-Kees RF Measurement and Engineering compiled useful information for engineers working with AM stations. Frank bases the information on his own experience and on documents available from Kintronic Laboratories (www.kintronic.com).

Frank has been called in after lightning hits to repair a number of antenna tuning units at the base of AM towers. Lightning knows no season! Frank’s summary keeps things simple and easy to understand.

First discussed are estimated impedances for a single reference tower that is series-fed, and operating at 1000 kHz (1 MHz) at heights of 150, 90 and 60 electrical degrees. Under these conditions, the values in the first table are typical:

(150 deg. height)     782R      –j13         (Capacitive Reactance

(90 deg. Height)     44R        +j18         (Inductive Reactance)

(60 deg. Height)     11R        –j113       (Capacitive Reactance)

If you are using an isocoupler on your (single) series-fed tower, it is assumed that the isocoupler has a typical capacitance of around 100 pF (or more). Thus, the isocoupler will present its added shunt value, to your single series-fed tower.

When the isocoupler’s shunt value is added in parallel to the impedance of your single series-fed tower, the addition of the isocoupler will shift the single tower’s impedance and typically yield the approximate values in the second table:

(150 deg. Height)      623R    –j315       (Capacitive Reactance)

(90 deg. Height)        45R      +j17         (Inductive Reactance)

(60 deg. Height)        10R      –j105       (Capacitive Reactance)

Frank adds that a single 90 degree height, series-fed tower will normally use a simpler ATU matching circuit. This circuit may be more efficient as a result of needing fewer components and lessened power loss, but this is debatable.

A single series-fed tower that is shorter than 90 degrees will yield a low R value with capacitive reactance. A single series-fed tower that is taller than 90 degrees will yield a higher R value with capacitive reactance.

Finally, it is worth noting that a tower height of slightly more than 90 degrees should yield an R value of approximately 50 ohms with a manageable reactance value.

Spring is in full swing for many readers. If you find yourself doing AM work and needing AM components, visit the Kintronic site.

Unbalanced-to-balanced adaptor

San Francisco contract and project engineer Bill Ruck has built a number of unbalanced-to-balanced adaptors over the years. He is careful to pay attention to absolute phase — if you’re not, the design can invert the audio.

There is an easy fix to this; the input inverting op amp output is connected to Pin 3. The inverted unity gain IC connection is Pin 2. Swapping Pins 2 and 3 will ensure that the output is in absolute phase with the input signal.

Bill prefers to use +/–15 VDC as a power source, but he has also used inexpensive DC-to-DC converters to take a nominal 9 to 12VDC signal and make +/-15VDC.

And Bill has found it wise to add a small capacitor across the op amp feedback resistor in order to limit bandwidth and make the amplifier stable. Although this is not critical, he tries to pick a capacitor value to be equal to the resistance at around 150 kHz.

Storage strap

Over the years, we’ve shown a variety of cable management solutions from brands like Velcro and other hook-and-loop manufacturers. But the one in Fig. 2 serves a dual purpose.

A heavy-duty hook-and-loop cable organizer.

The metal grommet helps organize and hang bundles of remote broadcast cables. In the Technical Operations Center, the grommet secures large bundles of cables, especially of the Ethernet variety. The fastener secures the cables without deforming the wire wrap. This heavy-duty nylon strap is available from Koppy and they come in small, medium and large sizes. There is a quantity discount.
