An Oklahoma licensee received a $3,500 notice of forfeiture for failing to file a license application for an FM translator on time.

Potter Radio submitted a construction permit for FM translator K236CT in Pawhuska, Okla., in January 2018 with a three-year expiration date of January 2021. On Aug. 4, 2020, Potter requested six months of additional time in which to finalize construct the translator due to construction delays caused by COVID. The Media Bureau agreed and extended the permit to July 4, 2021.

But according to the bureau, Potter Radio did not file a required covering license by that date and as a result the permit expired.

Later that month, Potter filed a petition asking the bureau to reconsider cancellation of the construction permit. The bureau treated the request as a waiver and agreed to reinstate permit, giving Potter until August 13 to file a covering license. Potter did so on August 2.

But when a permittee fails to file a covering license application on time — as required by FCC Rules — and instead continues operating, the commission considers it an act of unauthorized operation. In this case, the unauthorized operation lasted almost a month, giving the commission the authority to hold the party in question liable for willfully acting without a license and thus liable for a forfeiture penalty.

The FCC’s forfeiture policy statement establishes a base forfeiture of $3,000 for failing to file a required form and an additional $10,000 for operation without authorization. The commission also has the authority to raise or lower that amount as it sees fit. Based on the Media Bureau’s review of the facts and circumstances, it issued a $7,000 base forfeiture before again reducing that forfeiture to $3,500 because as Potter Radio is providing a secondary service as a translator station.

As a result, Potter Radio is required to either submit the $3,500 forfeiture or file a written statement seeking reduction or cancellation.

An image from the clearinghouse site shows the claims process. See the original at https://cbandrpc.com/resources.

The Relocation Payment Clearinghouse LLC is now accepting C-Band relocation claims through an online portal.

The RPC is responsible for collecting, reviewing and distributing payments associated with the relocation, as required by the Federal Communications Commission. This includes those who opted for the lump sum payment option.

“The RPC is ready to accept and review claims,” said Frank Banda, RPC program manager, in the announcement.

“If you have received your email invitation, we encourage you to set up your claimant profile as soon as possible. Setting up your profile and providing the requested information through our Coupa portal is the first step in requesting a lump sum payment or making a claim for reimbursement of actual relocation costs.”

This is the latest in a series of steps related to the FCC’s repurposing of the C-Band (3.7–4.2 GHz) by moving satellite operations to the upper portion of the band (4.0–4.2 GHz) and making spectrum available for other uses through auction.

The RPC website has information about how to establish a profile and submit a claim.

RPC LLC contracted with accounting firm CohnReznick LLP, law firm Squire Patton Boggs, satellite expert lntellicom Technologies Inc. and cable/broadband expert Reed Strategy LLC to perform the duties of the clearinghouse.

Across all users including radio, there are approximately 20,000 registered earth stations in the contiguous U.S. that are classified as incumbents for purposes of the C-Band transition, according to the FCC.

As of May, approximately 1,500 earth station operators, some with multiple licenses, had taken the “lump sum” election, according to data from the FCC. Those licensees that did not accept that option were able to work with their satellite provider or recoup justifiable filter, dish and labor expenses from the clearinghouse, for expenses associated with the transition or relocation.

The National Association of Broadcasters has released a letter concerning protocols for the upcoming show, Oct. 9-13.

In the letter signed by NAB EVP & Managing Director, Global Connections and Events Chris Brown, he said “we will require all attendees and participants to provide proof of COVID-19 vaccination.”

He added, “We think this is a positive step in reducing the spread of COVID-19 and will provide further details on implementation as well as other safety measures under consideration.” The letter did not address protocols issued at the end of July.

Brown cited consultations with “health and safety experts, gathering feedback from a range of exhibitors and attendees, and review of the safety measures recommended by national and local health authorities, including Nevada Governor Steve Sisolak’s important announcement this week regarding large events.”

Sisolak announced that large venues could eschew a mask requirement in exchange for COVID vaccination proof.

The NAB looks to be following the lead of the CES which earlier in the week announced a vaccination requirement for its show in January.

The Audio Engineering Society, with its annual show co-locating with the NAB Show, has also announced a similar vaccination requirement policy, excerpting the NAB letter in its announcement.

David Oxenford

Attorney David Oxenford blogs often about developments in the U.S. radio industry, and he has thoughts about the just-completed FCC auction.

He notes that almost a third of the available channels drew no auction interest at all, as we’ve reported, and he wonders if the results say something about the FCC’s local ownership rules.

Ninety-seven channels were sold, but 42, including four AM stations, went unsold in the auction. The commission will raise more than $12 million from the auction, but $9 million of that is from just two FM CPs in particularly desirable areas.

“The 42 channels that were unsold range from channels allotted to small communities in states like Wyoming or Alaska that were predicted to serve very few people, thus having opening bids as low as $750 that no one was willing to meet,” Oxenford writes on his blog, “to channels in somewhat bigger communities including channels in New York state and Colorado that had opening bids of $75,000, indicating that they would serve a substantial number of people, but the prices were apparently deemed too high to justify for companies looking for a business return.”

[Read: iHeart Snags a Sacramento FM CP in FCC Auction]

“This lack of interest may also say something about the FCC’s local radio ownership rules.”

Oxenford said he has been told that parties would have been interested in bidding on channels that went unsold but “because of the FCC’s ownership limitations, they were precluded from owning those stations. So instead of providing new service to the public, these channels will lie fallow, providing service to no one.”

He notes that comments on whether changes should be made to the FCC’s radio ownership rules are due Sept. 2 in the commission’s latest rule review. Some broadcasters want the FCC to lift the subcaps that limit how many stations one company can own in a market.

“The results of this auction may well be instructive on the issues that the FCC will be considering,” Oxenford wrote.

“In comments filed in 2019, parties talked about stations in their smaller radio markets that are essentially nothing but a transmitter and a computer — providing no real local service — when local owners who do cover the issues of importance to local communities are precluded from using these channels to provide new services, as the ownership rules do not permit such ownership.”

“There are still broadcasters who want to serve local communities, and as recent congressional activity has suggested, a recognized need for such local services,” he writes.

Quite a few devices in my broadcast technical environment report alerting information by email. I and others have come to depend on these alerts as what my Ops Manager Eric Thomas refers to as “the rhythm of life” as far as the radio station is concerned: pattern changes, tower lights on, like that.

In many cases these alerts come from old-school email origination clients without the ability to authenticate themselves.

These devices need a mail transfer agent or MTA that simply trusts and forwards, something you would never expose to the open internet. In addition, providers like Gmail and vtext have a variety of ways to detect and reject emails that are suspicious. It’d be nice if my mail was accepted without complaint or being bounced.

Like many firms of size, our company email has been SaaS outsourced to Microsoft 365, which requires meaningful email client authentication. The various broadcast devices I need to serve would never play nicely with an MS or Gmail directly. The system I want must live inside the private address, protective firewall environment of the corporate IT department. And it would be nice if it didn’t cost much.

This article takes you through the build process step-by-step for a send-only MTA. All it does is route alerts from your various non-authenticating devices to real-world email providers on the outside. It will not and should not receive mail.

Almost Anything Will Work

To begin the project, I found an old mid-tower Dell box in the recycling bin at the office. So my core system was free. So far so good. My application is low stress and almost any x86 castoff will work.

I updated the BIOS using the Dell tool and installed a 250-gigabyte flash drive. It could easily have been smaller, but it’s what I had. The box already sported a mighty 4 gigabytes of RAM. When this machine shipped it had Windows 7 Pro on it. It still had the hologram license sticker. Vintage 2013, Intel Core i3. Old, unsuited for office use, but more than good enough for this.

The next step was to load Ubuntu Linux 20.04 Desktop on it. Download a copy at ubuntu.com. The 2.7 GB download is an .iso file for which you’ll use your favorite DVD burner application to copy onto writable disk media or a thumb drive. Connect the box to a network segment that provides DHCP. Boot your boneyard PC from the media you created and install. If you see the choice, elect the “minimal” install. This skips the usual office desktop applications which aren’t needed for this.

Write down your username and password choices (because if you don’t, you’ll be repeating the install). Then open a terminal with CTRL-ALT-T key combination and make your first use of “sudo” which means, more or less, “super user do.” From the terminal you can invoke administrative privileges this way, needed for installation and configuration.

From now on, things you are expected to type will be bold, like… sudo apt upgrade, which will install the latest patches in case they aren’t in the .iso you downloaded. You might as well start from the latest and greatest. Everything is lower-case and yes, case matters. Do not type any punctuation marks. Answer “Y” when prompted and watch the process.

Next is the utility for remote terminal access… sudo apt install ssh, giving you the same terminal functions by IP address using an app like putty.exe. Check from another machine to confirm access via SSH. You can discover the machine’s DHCP assigned address with… sudo ifconfig which will probably complain that you need net-tools. Might as well add those using… sudo apt install net-tools.

You now have a generic Ubuntu Linux install. And for the record, this could probably be a Raspberry Pi just as easily as the scrap pile Dell I am using.

DNS Stuff

The process beyond this point requires two prerequisites:

1. You need a real registered host.domain hostname for your machine. Maybe you have a domain (and access to DNS records to assign its address and other attributes), or for a few bucks, just buy a name. If you buy one, make sure the name registrar provides DNS hosting. Most do for small operations like this.

1. You’ll need an actual registered (static) IP address, at least initially, to facilitate the creation of certificates and mail encryption keys, required for delivery to name brand mail service providers. Don’t worry, your MTA will retreat to the safety of a private address (i.e., 10.x.x.x, 172.16.x.x, 192.168.x.x) inside a proxy once it’s set up. But to get the needed badge of validity, it must stand on the street corner of the real internet for a few minutes.

Start with the prerequisites by choosing a name for your newly configured box. I suggest mail.your_domain_name.com. Obviously, replace “your_domain_name” with your domain name. If you chose some other name during OS install, don’t panic. Use the inbuilt nano Linux text editor to change it: sudo nano /etc/hostname. Replace the text as appropriate with the new hostname. Do the same with /etc/hosts: sudo nano /etc/hosts.

Commands are along the bottom edge of the little nano text editor. CTRL-O to write, RETURN, then reboot.

Using the config tool provided by your domain DNS host, create an A record using the full hostname you gave the mail server. Associate it with the public, registered IP address you will use temporarily. Create an MX record pointing to the same hostname.

Keep in mind that DNS records may take a bit of time to propagate across the internet. I suggest leaving the records you create permanently in place, even though they won’t point to the eventual resulting system anymore. Some mail providers check to see if your hostname is a real box.

Now let’s install the MTA software: sudo apt install mailutils.

When you eventually get a choice dialogue box, choose “Internet Site,” which is the default. Then tab to OK. If it asks for a system mail name, it’s the same name you gave the server you are installing on.

To do what we want, Postfix will require a bit more configuration. Proceed to the text file /etc/postfix/main.cf: sudo nano /etc/postfix/main.cf.

You’ll need to locate a few lines of the file for editing, so this would be a good time to test out the CTRL-W command in nano to find, first: mydestination = $myhostname, your_domain_name, localhost.com, localhost.

Substitute your domain name as indicated. $myhostname is a variable set earlier in the file by a “myhostname =” statement. Might be good to check that info is correct, but Postfix usually gets this right on install.

Then find… mynetworks =  and change it to read mynetworks = 10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 to allow all the ranges of non-routable private addresses. These are the mail originating devices allowed to use your MTA for outbound messages.

The example config I show gets the whole universe of private IPv4 addresses. If you wish, you can restrict down to the individual device by using a complete address and /32 as the CIDR mask. Or anything in between. This is your gatekeeper. Let paranoia be your guide.

At this point save your changes to main.cf and restart postfix to allow the software to read the changes: sudo systemctl restart postfix.

Testing, testing…

Let’s test your server from the terminal (CTRL-ALT-T) with… echo “This is a test of email” | mail -s ” This is the subject line of the test” your_email_address.

Some receiving domains will probably accept the mail. Outlook.com (MS 365) might, but it’ll probably show up in junk or clutter. Vtext.com (Verizon email to text conversion) probably will as well and display in cellular text. Google Gmail won’t accept it at all; it’ll get bounced. So there is more to do. Time to enable encryption, certificate validation and transport layer security (TLS).

Meanwhile, take a look at the logging that Postfix provides, as it will tell you exactly what happened in the interaction with any outside service. Linux provides a nice utility to look at the last few lines of a log file and even monitor it as lines are added: sudo tail -f /var/log/mail.log (note: your install may name this log file differently, but it will be in the folder /var/log). Also notice that the -f argument makes the utility display new lines as they are appended in real time. You can have more than one terminal instance open at a time, allowing you to watch what happens with the gmails of the world in real time.

Next up is the authentication piece that real email services will be looking for from your MTA.

Let’s get the needed credentials from the free Let’s Encrypt folks. Consider making a contribution to their efforts. sudo apt install certbot.  As always, press “Y.”

Then sudo ufw allow 80. This tells the UFW firewall to open a port for HTTP. The command should answer with confirmation that it opened the port. Certbot’s process will reach out and “Let’s Encrypt” will reach back over port 80 to confirm the host presence at the address claimed, using the DNS records you created. But certificate information doesn’t include IP address directly, so a later move to a private address inside the firewall shouldn’t break anything.

Now let’s create a certificate that identifies this server as within the domain you’ve placed it in and provide a public key to go with the private key that’ll be stored on this host. sudo certbot certonly –standalone –rsa-key-size 4096 –agree-tos –preferred-challenges http -d your_domain_name (those are double dashes, by the way).

When complete, you should see this:

 

If it doesn’t work, check your DNS configuration, or maybe just wait a while and try again. When it completes, pay attention to certificate expiration.

Now let’s tell our server where the keys are kept. Back to the postfix config file we go:

sudo nano /etc/postfix/main.cf.

Under # TLS parameters find:

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem

smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key

 

and change it to:

smtpd_tls_cert_file=/etc/letsencrypt/live/your_domain_name/fullchain.pem

smtpd_tls_key_file=/etc/letsencrypt/live/your_domain_name/privkey.pem

 

Finally, to further satisfy Gmail, add the line: “always_add_missing_headers = yes”.

Save, exit nano then restart postfix: sudo systemctl restart postfix.

If all went as described (it should have), then you have a mail transfer agent. Any mails from your devices, pointed to the private address the server has, will be forwarded to whatever mail service is indicated.

Finally, you can disconnect from the public internet (the registered static IP), bring this server inside the firewall and give it a private address.

Use the desktop “settings” tool to change the IP. So long as port 25 is open through the firewall, you are all set. Just point your various reporting devices to that same private address and watch the alerts flow.

If it doesn’t work, check your DNS configuration or maybe just wait a while and try again. When it completes, pay attention to certificate expiration. In my case, using GoDaddy DNS, I had to assign the IP address to my machine that is associated with the your_domain_name DNS entry. Your DNS provider may work differently. The error messages that certbot sends are helpful for Googling.

Now let’s tell our server where the keys are kept. Back to the postfix config file we go.

# Raspberry Pi differences:

1. Enable SSH terminal access using the raspi-config tool
2. net-tools are already installed in the Raspi Lite .iso
3. Use raspi-config to change the hostname
4. mailutils does not include postfix when pulled from the raspi repositories. sudo apt install postfix

It doesn’t take a lot to create a functioning MTA out of equipment already on hand. Having that functionality will ensure that important status and warning messages get through, which will make the engineer’s job easier and provide for faster responses to anomalies.

Dear Radio World,

The advice that appeared at the end of a March Workbench column about resetting a generator fault remotely is something I discourage strongly.

Besides clearing the fault and possibly the run-time and error logs, cycling the DC power to the controller may also clear the real-time clock and reset the exercise timer, and may leave the generator in an offline state until the clock and timer are manually set.

As stated in the tip, you have no idea why it faulted in the first place. Attempting a restart without an inspection or a person present could result in catastrophic damage to the genset, a fire (if there was a fuel leak), or even harm to a technician who might be working on the unit and could have even been the cause of the fault or shutdown.

If there was a mechanical failure, running the engine without repairing the damage first could make things even worse.

I bet a generator technician reading the tip would cringe. Of course your local generator sales person would love to take this opportunity to sell you a new generator.

My own home standby generator, a Kohler 14RESA, resets just the clock and exercise timer if the battery is disconnected; the run-time and error logs are maintained in nonvolatile memory. But it won’t run until those two items are set. For safety reasons they tell you to disconnect the incoming AC power as well as the battery whenever you service the unit, but I find it more convenient to do neither of those things but just press the OFF button when doing the annual maintenance (oil, spark plugs, and filter changes).

Several organizations that push for diversity and civil rights are urging Congress to reinstate the minority tax certificate program.

“Supporting these pieces of legislation would eliminate barriers and create new opportunities for women, people of color and socially disadvantaged individuals to own local TV and radio stations,” they wrote to congressional leaders.

The letter supports H.R. 4871, the Expanding Broadcast Opportunities Act of 2021 introduced by Reps. G.K. Butterfield of North Carolina and Steven Horsford of Nevada, and S. 2456, the Broadcast VOICES Act, introduced by Sens. Gary Peters of Michigan and Robert Menendez of New Jersey. All four are Democrats. Menendez has been pushing for reinstatement since at least 2008, when he introduced a similar bill.

The bills would authorize the Federal Communications Commission to reestablish what would now be called a Diversity Tax Certificate Program.

Individuals who donated broadcast stations for the purpose of training socially disadvantaged individuals in the management and operation of stations would be eligible for a tax credit equal to the fair market value of the station.

The joint letter is from the Multicultural Media, Telecom and Internet Council, the National Association of Black Owned Broadcasters, the National Urban League, United States Black Chambers, Asian Americans Advancing Justice, the League of United Latin American Citizens and the Hispanic Federation.

“From 1978 to 1995, when the diversity tax certificate was instituted, it was an effective mechanism for bringing more people of color into station ownership,” they wrote.

“During this time, broadcast ownership by people of color increased by more than 550%. The elimination of the diversity tax certificate in 1995 disproportionately affected that rate. According to data from 2017, women make up less than 6% of broadcast TV station owners, and people of color account for less than 3%. Similarly, women own just 7% of broadcast radio stations, and people of color own less than 3%.”

“CES will be in person in Las Vegas in January 2022, and we will require all attendees to be fully vaccinated.”

That’s according to Gary Shapiro, president/CEO of the Consumer Technology Association.

“We have seen a spike in cases due to the Delta variant, which is severely hurting the unvaccinated population,” Shapiro wrote in a blog post today.

“Yes, there are breakthrough cases for the vaccinated, but many of those have few or no symptoms at all. And of the vaccinated getting the Delta variant, only a tiny percentage are hospitalized.”

“We prioritize the safety and security of CES participants.” Shapiro called it a “major decision” to require vaccinations.

“We are also assessing proof of a positive antibody test as a requirement and will share more details on this later. Importantly, we will continue to follow state and local guidelines and recommendations by the CDC and will announce additional protocols as we get closer to the show.”

Shapiro said that the past 18 months have been “a roller coaster of emotion” for him as a CEO “as I work to lead by example and make decisions that will have positive effects.” He described the difficult decision not to do last year’s event in person and the need to lay off employees last year because of the pandemic.

“We all play a role in stopping the spread — requiring proof of vaccination for CES 2022 is one way we can take responsibility on our part.” He said those who choose not to attend will be able to experience the show online.

In a separate email to the show community, Veronica A. Lancaster, vice president, Standards Programs, said the requirement to provide proof of vaccination will affect all attendees, support staff and exhibitors’ staff.

“CTA decided this based on today’s science which shows that vaccines offer us the best hope for stopping the spread of this pandemic. … While we are still more than five months from CES 2022, we want to communicate this decision early to give you time to plan. CTA is also assessing the acceptance of proof of a positive antibody test as an alternative requirement and will share more details on this later.”

CES has a page with info about health protocols.

Dear RW,

Cris Alexander’s delightful reminiscing on changes in audio processing (“Air Chains Then and Now” ) brought back memories of when I was hired by GAF Corp. in 1976 to rebuild and manage New York’s Classical WNCN, 104.3 FM.

We started with a blank sheet, and the first thing GAF’s chairman did was to retain the services of the legendary Dick Sequerra to handle all aspects of the audio chain. 

The chairman was an audiophile, and had one of the amazing Sequerra FM1 tuners in his home. Of course, we had one in our main studio as an off-air monitor, too.

As our studios and offices were located in a building on Sixth Avenue, and the building’s foundation went straight down to the Sixth Avenue subway, the studios were built as rooms within rooms, with the inner rooms mounted on rubber dampers that resembled hockey pucks.

Sequerra hired WFMT Chicago CE Al Antlitz to design and fabricate the boards used in each studio. Their performance was far superior to anything available in the marketplace and greatly added to the very clean sound that he wanted to achieve.  

Sequerra hoped to broadcast the way that the BBC did with its Classical channel, requiring the announcers (presenters) to ride gain, with no processing. AFTRA, the announcers’ union, mandated that wasn’t about to happen, so we ended up with the then-new Orban processors, which really were superior to anything else on the market. 

As part of his passion for excellence, Sequerra went into the bowels of Manhattan and rebuilt the telco amplifiers going from our studios to the Empire State Building, unknown to New York Telephone, of course.

After the new Gates transmitter was delivered to our space in the Empire State Building, Sequerra spent three days tearing the transmitter apart and rebuilding it to his specs. The performance was just spectacular! My memory is not absolutely perfect here, but as I recall, with the Orban bypassed, the lines were clean to something in the –90 dB area. 

There is no doubt that Dick Sequerra’s passion and expertise made WNCN the best-engineered FM station in the country. The programming team was led by a Julliard graduate, and the combination made WNCN a leader in the country’s Classical music FM stations.

Thanks for the memories.

This plastic cap was an inexpensive deterrent to insects that would otherwise nest in the feed horn.

Steve Tuzeneu is a longtime broadcast engineer and Workbench contributor, and the general manager and CE of WIHS(FM) in Middletown, Conn.

Steve had a problem: a lost satellite signal; but he was able to track the problem to wasps that had taken up residence in the feed horn.

After removing them and their nest from the throat of the feed horn, Steve wanted to stop them from coming back. Fig. 1 shows Steve’s solution: a plastic cap from a used can of aerosol glue. The cap happens to fit nicely into the feed horn, discouraging any insects from moving in.

Keep this solution in mind, especially if you suddenly lose your satellite signal. As a contractor, I once was called to a station that reported losing its satellite signal every evening at sundown. Yep, you guessed it: Bees had taken up residence; during the day they were mostly away from the nest, but at night they all returned, and their combined body mass was enough to disrupt the signal.

Whether it’s a plastic cap or a cut-down 1-liter plastic water bottle, Steve’s tip will save you a headache and maybe prevent you from getting stung.

 

Analog at the Edge

I got a followup from engineer Dale Lamm about the AoIP EAS adapter we discussed here in July.

“I’ll confess, when I first saw the tip about the AoIP/EAS interconnection, I thought it was an April Fool’s article that was somehow delayed,” he wrote.

Dale Lamm wasn’t sure at first that we were serious with our tip about the AoIP EAS adapter in the June 23 issue.

The CATV F connector adapting to an RJ-45 Ethernet plug was something he had never encountered. A clever engineer from WETA found this adapter and used it to solve a problem that had nothing to do with CATV.

But where did this odd adapter come from in the first place?

It starts with someone who wanted to install a TV set in a room that had nothing in the wall but Ethernet category wiring. There was no RG-6 coaxial wiring in the room.

With a pair of these adapters, you take RF from the CATV distribution amp and send it on one of the twisted pair inside the category cable.

In the room, another adapter takes it to an F connector that is attached to the TV. The 100-ohm twisted pair is close enough to the 75-ohm RG-6 impedance for this to work. Obviously, use a direct category cable connection. Don’t expect to shove RF through a network router!

Looking closely at the picture in our original article, it seems only the first pair is used. Moving consumer S/PDIF to professional AES with this adapter solved a problem inexpensively.

Dale’s plant makes partial use of audio over IP but has a lot of gear with analog I/O. He was never a big fan of dongles with twin XLR connectors hanging off the back of a dense array of rack gear. He finds it easier to modify a LAN cable — cut off one end, fan out the four pairs and solder the left/right pairs to a couple of XLRs that plug into the analog gear.

Use some tubing or heat shrink to make it pretty and more durable. Running balanced analog through 10 or 20 feet of unshielded category cable is fine.

If you use the hanging dongle method, you’ll be soldering an XLR at each end of the interconnection. Dale’s method requires an XLR only at the analog equipment end, and results in less wiring congestion. Less dense rack wiring can save time troubleshooting in the future.

Note that LAN patch cables use stranded wire instead of solid if you’re concerned about flexure.

Someday, everything will be AoIP-ready or shrunken into a piece of software inside a server. For now, we all have to deal with analog at the edges of our facilities.

Dale “Squeak” Porray, AD7K, really liked Bill Weeks’ submission about the LED replacement for fluorescent Circline bulbs but says the website link we gave may not have been right in some versions of the story. It is www.mpja.com for Marlin P. Jones Associates.
The site now has over 60 YouTube videos of the products they sell. Squeak has been dealing with them since the 1970s and says they’re a fine company.
Since we also were talking about Cat-5/6 Ethernet cables, watch the site’s YouTube video about the LAN RJ Plug Crimp Tool. It has a built-in cable continuity tester to check cables you’ve crimped, all for under $30. One notable feature is a ratchet release pin, very important!

Once while helping an engineer crimp cables, we took a break, but as we chatted, he inadvertently put his index finger in the jaws of the crimping tool and pressed down. CLICK — the jaws latched. And there was no release.

I drove him to the emergency room to get his finger freed. Since witnessing that, I’ve made sure that any latching pliers or crimping tools I use have a release pin. You can’t be too careful.

The AM radio station formerly known as WMBI no longer has those historic call letters. It officially is now WXES.

That’s just one of the call sign changes reported by the FCC for the month of July, and probably the one involving the most famous call letters.

The station, which airs at 1110 kHz in Chicago, was acquired by El Sembrador Ministries from Moody Bible Institute of Chicago in July. Moody still owns WMBI-FM.

Moody had announced earlier that it planned to sell the AM station, which is considered one of the oldest noncommercial Christian radio stations in the country.

WMBI had been Moody’s flagship dating to 1926, and its call letters referred to the organization’s name. Moody had switched the station to Spanish-language Christian programming in 2012.

Here’s the list of 22 call sign changes in July (PDF).

Expanding on its existing relationship with Mercedes Benz, Xperi announced that HD Radio receivers will be available in digital dash displays of Freightliner Cascadia trucks early next year.

Xperi SVP/GM Jeff Jury said in an announcement that the Freightliner Cascadia “will be the first commercial truck to fully implement HD Radio technology in its cab.”

Daimler Trucks North America is the parent of the Freightliner line.

The two companies have worked together before, including in the hybrid radio space. Xperi’s DTS AutoStage system was introduced to the market in the Daimler MB User Experience (MBUX) in the 2021 Mercedes-Benz S-Class.

Xperi says HD Radio technology is now available from approximately 40 manufacturers in about 200 vehicle models and that it is in 75+ million vehicles.

The author is general manager, KTRL/KXTR, Tarleton State University.

I manage two stations at Tarleton State University in Stephenville, Texas, and we have used Tieline’s Report-IT app and iMix G3, Commander and Merlin codecs in the past.

Recently we purchased the Tieline Gateway 8 to use for sports and other remote broadcasts on KTRL(FM) 90.5 MHz and KXTR(LP) 100.7 MHz. Some Gateway channels are hooked up to a Logitek console in one studio via a JetStream Mini, and others are hooked up to the Logitek console in our other studio. Codec outputs are networked across to all three of our Logitek consoles, including a production suite.

KXTR is heard in Erath County, and KTRL covers a large section of North Central Texas and reaches Fort Worth and the outskirts of Waco. Both stations are also streamed online.

We selected the Tieline Gateway 8 as it streamlined our setup by using a single codec for remotes on both stations. Tieline’s upgrade path allows us to expand channel capabilities via software upgrades in future as required.

 

My “Go-to”

The new Gateway 8 replaces an older Commander codec being used for remote broadcasts across our campus and community. It also replaces a Tieline Merlin in preparation for the football season here at Tarleton State.

We use the Gateway to send live audio back to the station and send station mix-minus audio to the remote site. The Gateway delivers flexibility. We can handle two sports broadcasts on both stations or be doing a remote broadcast on campus on one station, and a sports broadcast on the other.

Tieline is my go-to for remotes. Its integration with older equipment and being able to use the Report-IT app are major reasons. We replaced our iMix G3 with the ViA, and our Athletics department has done the same, so we are using Tieline ViAs for all our remotes nowadays. We will use the Commander and iMix G3 that they replaced as a backup STL.

The transition was pretty simple. Like the Gateway, our Logitek console uses RJ45 for the ins and outs. With the Merlin and Commander we had to use RJ45-to-XLR adapters, but with the Gateway we can get rid of those and go straight in/out.

The university has a fiber-based IP network, and we use AT&T hotspots to connect on-site. Our athletics team uses AT&T and Verizon. Connections are reliable in this area, but with sports broadcasts, that can depend on where an away game is located.

Quality and functionality is the best part about broadcasting using IP codecs. When you compare codecs to a cellphone or POTS line, the overall quality difference with Tieline is undeniable.

During the pandemic we worked with a staff of three, myself and two student workers. We actually used Report-IT, along with our Commander and eventually Gateway more than ever before. It was the best way for us to put students on the air. They can download the TieServer Console and Report-IT apps on their phone and we could put them on the air in a snap.

The Tieline Toolbox Web-GUI for configuration and control is easy to use and very helpful for configuration and control. Tieline’s Cloud Codec Controller is also something we plan to use for remote control of equipment. We have a lot of students and play-by-play announcers doing broadcasts who are not very familiar with the equipment, so being able to control everything remotely would be incredibly useful.

Tieline’s quality is great. It is the best of any other options we have used in the past and we have had nothing but great experiences with Tieline’s technical support. We have had very positive feedback from our engineer and all of the people who use the equipment on a weekly basis. They have been some of the most reliable and best working pieces of equipment we have.
