Video: Watch students at KSDB perform a numbers station radio drama

Many thanks to SWLing Post reader, James Copeland, who writes:

I have enjoyed reading the SWLing Post for years and appreciate all your hard work. I wanted to share something with you that might interest the readers.

A few months ago, I was inspired to start writing a radio drama about a number station after reading an article on the SWLing Post about someone working at a number station.

I am the program director for the student-run radio station at Kansas State University, and we performed this drama live last Tuesday on our radio station.

The plot follows a worker at the station who has to decide what to do when she learns that the numbers she reads end up killing people and could start a nuclear war.

There are also a lot of short recordings from various active and inactive stations, including one of my recordings of HM01 at the end of the show.

We at KSDB love producing radio dramas and make them just like the golden days of radio with as many live sound effects as possible.

Many thanks for sharing this, James! I love it!

I listened to the audio as I hiked this afternoon–I actually prefer “theatre of the mind” without visuals with the first listen. Now I’ll watch the studio video and enjoy the reading, sound effects and direction!

James, you’re welcome to share your radio dramas here anytime! Bravo for putting together such a cool little radio drama. I love the off air numbers station recordings and clips!

A Guntersville man is being slapped with a $15,000 fine from the Federal Communications Commission. They say he’s been operating an illegal radio station.

Some people in the neighborhood say they were aware of Michael Dudley’s radio operation. Others say they weren’t, but many people say it’s a pretty stiff penalty.

The FCC shut down the makeshift radio station running from Dudley’s home. In documents from the FCC, Dudley was confronted twice last year for sending music through the airwaves on 103.9 FM without a license. The first time was a warning. The second prompted the fine.[…]

NAB: “Setting the record straight on FM radio in iPhones”

(Source: Contributor Sam Matheny via the NAB Blog)

In recent months, the Southeast U.S., Puerto Rico and the U.S. Virgin Islands have been pummeled by Hurricanes Harvey, Irma, and Maria. The wildfires in California have been equally devastating. These storms and fires have wreaked havoc on communications networks and challenged public safety officials’ ability to get lifeline information to affected residents.

At a time when many Americans have come to rely on their smartphones, massive cellular outages were suffered from Texas to Florida on an even greater scale than in Superstorm Sandy five years ago, and California has also suffered major outages in key locations. In Puerto Rico and the Virgin Islands, it may take weeks and even months to fully restore cellular service because of the damage to the electric grid. This has been a painful reminder of the need for a redundant and pervasive communications infrastructure, especially in times of disaster and emergency.

Radio, television, cellular, satellite, and other communications networks all have a role to play in a crisis. In the wake of these storms, a passionate discussion about activating FM radio in smartphones – and, specifically, Apple’s iPhone – has emerged. This discussion was started by those most impacted by Irma when the South Florida Sun-Sentinel editorialized on the issue and Senator Bill Nelson of Florida called for activating FM chips in smartphones. FCC Chairman Ajit Pai also issued a public statement calling for Apple to activate FM chips to promote public safety and FCC Commissioner Jessica Rosenworcel also weighed in with her support.

There has been a good bit of technical back and forth since these calls to “light up the chip,” and this is my effort to try and set the record straight.

Here is the BLUF – Bottom Line Up Front

Apple has built and offered a wonderful FM app in their iPod Nano for many years. They know how to make FM work, and work well, in their mobile devices. Apple even wrote its own Nano app that allows the user to pause live radio and buffer up to 15 minutes of content.

However, Apple has specifically chosen not to offer this functionality in their iPhone. Indeed, Apple has disabled FM chips despite the capability being available on the communications module within the iPhone. This means other app developers cannot offer FM apps either.

Apple CEO Tim Cook hails from Mobile, Alabama and attended Auburn University. Mobile has been impacted by at least 10 different hurricanes since 1969 and that was prior to Nate, which brought a nearly six-foot storm surge and flooding, so I have to believe Mr. Cook has a personal appreciation for the damage these storms can inflict. We invite him and Apple to reconsider activating FM radio in iPhones, and we stand ready to work together to enable this important service.[…]

Weather Radio Review: Steve recommends the Sangean CL-100

3 Replies

Many thanks to SWLing Post contributor, Steve Lebkuecher, who comments on our recent post about weather radios:

I have the Sangean CL-100 and highly recommend the radio for several reasons and in fact I bought several for family members as gifts. The Sangean CL-100 looks like an alarm clock and is what I use as an alarm clock but the CL-100 is a full featured weather radio as well.

The audio quality for general broadcast is excellent for a radio this size and the build quality is very good. I bought mine several years ago and have not had any issues. (About $60.00 from Amazon)

Some of the features I like and why:

S.A.M,E (Specific Area Message Encoding) Alerts only for your county. If a thunderstorm passes through a county next to you at 4:00 AM you will not be woken up. This has happened to me several times with my previous non S.A.M.E radio and I just ended up turning the radio completely off which obviously left me vulnerable to the next event.

Selectable Alerts – disable alerts that you may not care about such as wind advisory. Again I have been woken up with my previous weather radio that didn’t have this feature for a wind advisory early in the morning. Very irritating.

End-of-message (EOM) Radio turns off after alert is given so you don’t have to get out of bed just to turn the alert off.

RBDS (Radio Broadcast Data System) You can set the radios clock as well as the radio will display station ID and song name.

Display is excellent and has a wide viewing angle plus you can adjust the brightness. I do wish the display was a little bigger and mounted on the front of the radio VS the top so it would be easier to see the time if you wake up during the night.

Two separate alarms and can be programed for different days of the week.

Human Wake-up System – Alarm starts at a very low level and gradually builds up in volume. You can set the alarm to buzzer or radio broadcast. I hate being jolted out of bed by a nasty sounding alarm.

The jacks include DC power in, stereo earphone, AM external antenna, FM/weather external antenna, aux-in, external alert and grounding terminal.

Thank you for your review of the CL-100, Steve! I had forgotten about this particular weather radio and didn’t realize it was still on the market. I now recall an earlier post where Jeff McMahon touted the CL-100.

I love the CL-100 display and the fact that it doubles so well as a proper alarm clock. At time of posting, I notice one on eBay for $44 shipped–I hope someone buys it before I do. (Seriously–I’m very tempted.)

FCC lifts local control rule for radio stations

5 Replies

(Source: The Washington Post)

Federal regulators have voted to eliminate a longstanding rule covering radio and television stations, in a move that could ultimately reshape the nation’s media landscape.

The regulation, which was first adopted almost 80 years ago, requires broadcasters to have a physical studio in or near the areas where they have a license to transmit TV or radio signals. Known as the “main studio rule,” the regulation ensured that residents of a community could have a say in their local broadcast station’s operations.

Tuesday’s vote by the Federal Communications Commission lifts that requirement. With the rise of social media, the agency said, consumers now have other ways to get in touch with their local broadcasters.

“Additionally, technology allows broadcast stations to produce local news even without a nearby studio,” FCC Chairman Ajit Pai said.

But that same technological capability could prompt large media titans to take over small, local TV and radio stations, turning them into megaphones blasting content developed for a national audience rather than a local one, according to critics.[…]

FCC asks Apple to activate iPhone FM receivers

7 Replies

My Android FM receiver app.

Many thanks to SWLing Post contributor, Dan Van Hoy, who forwards the following story from The Verge:

FCC chairman Ajit Pai wants Apple to turn on the FM radio that’s hidden inside of every iPhone. In a statement today, he asked that Apple “reconsider its position, given the devastation wrought by Hurricanes Harvey, Irma, and Maria.” The FM radio, he said, can be used to receive “life-saving information” during disasters.

Apple said Pai’s request wasn’t possible for its newest phones. “iPhone 7 and iPhone 8 models do not have FM radio chips in them nor do they have antennas designed to support FM signals, so it is not possible to enable FM reception in these products,” an Apple spokesperson said in a statement. Apple seemed to indicate that it had no plans to enable FM radio on older phones either, saying that the iPhone already includes other safety features.

Most smartphones have an FM radio inside, and they have for a long time. Until recently, however, most of those radios were deactivated, so that owners couldn’t use them. There were a handful of reasons for this, but two of the more obvious ones were that if your phone receives FM radio, you’re going to be less likely to pay for music and extra wireless data — instead, you’d just tune into the radio for free.[…]

Dan notes: “The one false part of Apple’s response is about the antenna. Earbuds are used for the FM antenna in mobile phones. I use mine often when I travel.”

That’s correct, Dan–I use my Moto phone’s FM receiver a lot when travelling and, in fact, it requires earphones to operate. Some of the latest iPhones don’t even have earphone jacks, but most previous models did.

It’s too bad Apple won’t allow for the receiver to be unlocked in the models that do have FM radio. It’s such a great, accessible and free feature.

Thanks again for the tip, Dan!

NASB: “Digital Radio Mondiale Delivers at IBC 2017”

Digital Radio Mondiale Delivers at IBC 2017

Participants in the four DRM events organised at IBC by Gospell, Thomson Broadcast, Nautel and Ampegon between 15th-17th of September have had an insight into a wide range of DRM activities, from big projects in Morocco (Thomson Broadcast), India and Hungary (Nautel), to the progress of DRM in South Africa. And DRM used not just for broadcasting but for other vital activities was demonstrated by Rfmondial involved in a wide-ranging application for the US Coast Guard.

One constant for all events, each unique and so different from the other, was the positive messages about DRM in both AM and VHF and the increasing availability of new receiver and receiver solutions, many always on display. The first event on Friday the 15th (Gospell) saw the launch of GR-227 the multi-standard (DRM/DAB/DAB+) car adaptor that is compatible with any car stereo with USB port and able to work with Android Smart Tune App. As the manufacturer explained, this after-market solution can be a significant development allowing digital reception in cars initially fitted with analogue receivers.

Of equal major interest was also the Titus II multi-standard digital radio receiver produced by Titus SDR, a division of PantronX. The consumer software-defined radio digital receiver platform, which is the result of collaboration between Titus SDR/Patron X, Jasmin-Infotech, TWR, and Fraunhofer IIS, supports multi-standard radio reception, including DRM, DAB and DAB+ and core data applications. The representatives of PantronX and TWR received lots of questions about this receiver system based on a custom Android tablet platform, featuring multipoint touch, WiFi/Bluetooth and stereo sound.

Other receiver possibilities: the tablet solution presented by Fraunhofer IIS, the Indian receiver Avion, and a new concept DRM receiver produced in South Africa all enforced the idea that the excellent work done by transmitter companies like Thomson Broadcast, Nautel and Ampegon in providing a digital transmitter infrastructure in many parts of the world can link now with the innovative receiver solutions.

The Thomson event came alive with the presentation about the huge project in Morocco and the Nautel event attracted lots of guests already familiar with the big projects of this established transmitter manufacturer recently in India and now in Hungary.

The last of the DRM events, hosted on the 17th by Ampegon was a moment of celebration. First of this company (now 75 years old) displaying solid-state transmitters of all capacities successfully used globally, as well. As Ampegon has been also involved in Africa and supported the first DRM trial in South Africa two years ago, they were the natural hosts of a special DRM award moment. The DRM Enterprise Award 2017 (Africa) has been awarded to 3 pioneering experts in promoting DRM digital radio in South Africa. The winners are Dr Roelf Petersen on behalf of Radio Pulpit (member of the Pulpit Media Group) and Broadcom International involved in the trial of DRM in mediumwave. The other two winners Thembeka Khaka (Thembeka Khaka and Associates) and Johannes von Weyssenhoff have been very active in getting the legal framework and conducting the current trial (DRM for local coverage) that is taking place in conjunction with a community station in Johannesburg. (This event was streamed on Twitter click here to view.)

As Ruxandra Obreja, Consortium Chairman, remarked: ”All those who have hosted successful DRM events, the new and old supporters and specialists interested in digital radio and DRM, all the other companies supporting DRM and present at IBC (BBC, Babcock, Becil, RFI, Riz, NXP, Rfmondial, Sentech, to mention just a few) all the guests from countries as far apart as India, Argentina, the Netherlands, Belgium, Pakistan, the Philippines have seen how much effort goes so that DRM can deliver for all, globally.”
