Variety: Legacy Radio “Faces a Grim Future”

Traditional Radio Faces a Grim Future, New Study Says

A new study published today by the head of New York University’s Steinhart Music Business Program casts a sobering outlook on the future of terrestrial radio.

In the 30-page report, Larry Miller argues that traditional radio has failed to engage with Generation Z — people born after 1995 — and that its influence and relevance will continue to be subsumed by digital services unless it upgrades. Key points made in the study include:

*Generation Z, which is projected to account for 40% of all consumers in the U.S. by 2020, shows little interest in traditional media, including radio, having grown up in an on-demand digital environment;

*AM/FM radio is in the midst of a massive drop-off as a music-discovery tool by younger generations, with self-reported listening to AM/FM radio among teens aged 13 and up declining by almost 50 percentage points between 2005 and 2016. Music discovery as a whole is moving away from AM/FM radio and toward YouTube, Spotify and Pandora, especially among younger listeners, with 19% of a 2017 study of surveyed listeners citing it as a source for keeping up-to-date with music — down from 28% the previous year. Among 12-24 year olds who find music discovery important, AM/FM radio (50%) becomes even less influential, trailing YouTube (80%), Spotify (59%), and Pandora (53%).

*By 2020, 75% of new cars are expected to be “connected” to digital services, breaking radio’s monopoly on the car dashboard and relegating AM/FM to just one of a series of audio options behind the wheel. According to the U.S. Department of Transportation, the typical car in the U.S. was 11.6 years old in 2016, which explains why radio has not yet faced its disruption event. However, drivers are buying new cars at a faster rate than ever, and new vehicles come with more installed options for digital music services.[…]

WWII Radio: Truman and the Scott Radio Labs RBO-2

Many thanks to SWLing Post contributor, Kim Elliott, who recently shared the photo above of President Harry S. Truman via @RealTimeWWII.

If I’m not mistaken, that is a Scott Radio Labs Model RBO-2.

I’m guessing that’s also the speaker mounted on the wall directly above the receiver.

Scott Radio Labs marine receivers were shielded to the point that they had very low local oscillator radiation. This design prevented detection of the ship via the enemy’s use of radio direction finding gear.

I have a commercial Scott Marine Radio Model SLRM–it is my favorite receiver and I use it daily.

Post readers: Anyone else have a Scott Radio Labs receiver in their shack? Please comment!

Leaving a comment? reCaptcha is back…for now…

Seriously…we know you’re not a Robot!

If you’ve been an SWLing Post contributor for a few years, you’ll recall that we used to use Google’s Captcha system to prevent SPAMbot comments on our site.

A few readers complained about how difficult the Captcha system was at the time (and I agreed with them), so we removed Captcha. At the same time, I implemented a stronger backend system for flagging SPAM comments. You’ve likely noticed many of your normal comments are moderated automatically–we try to approve them within a couple of hours.

Spambots are a real pain: they attempt to leave phony comments on our site in an effort to link back to their target site (some of which are loaded with malware).

How many SPAM comments do we get from Spambots and other Spammers?  Here are the statistics from our anti-SPAM system:

After we removed Captcha, the more clever SPAM comments would still make it through the various filters and fall in a moderation pile. At first, this amounted to, perhaps, a dozen or so comments to moderate each day. Lately, the number has become overwhelming–closer to 12+ per hour falling in the moderation queue among legitimate comments.

“Separating the wheat from the chaff” has become a full time job. 🙂

Until I can find a user-friendly solution to this, I’ve implemented Google’s latest system called reCaptcha. It has its quirks and presents interesting challenges, but I believe if you’ve used it on other sites and proven you’re not a robot, Google remembers and all you have to do to prove yourself is check/tick the box next to “I am not a robot.”

Anyway, I just ask for understandnig as I sort out a more simple solution to SPAM-proof our site!

Hurricane Harvey: Mike stresses the importance of local AM radio

Earlier this week, I received a message from my good friend, Mike, who lives south of Houston in Galveston County, Texas. Mike noted:

Here in Texas, we’re still dealing with the impact of hurricane Harvey.

[…]The absolute best hurricane information came from AM 740 KTRH Houston. A 50,000 Watt AM transmitter that covers a major portion of the gulf coast.

I’m learning that the Corpus Christi AM news station was evacuated and secured operations. KTRH kicked in and served the listening public very well.

I haven’t heard from Mike in a couple of days and, since then, Harvey has caused unprecedented levels of flooding in south Texas. I hope he’s doing okay and hope to hear from him soon.

Indeed, I hope SWLing Post readers in the affected area, their friends and family have all made it to safety.

Video: Shortwave shootout with the Tecsun S-8800

After enjoying an afternoon testing the Tecsun S-8800 on the Blue Ridge Parkway this past weekend, I decided to return to the parkway yesterday and test the S-8800’s shortwave performance.

I carved out about two hours of my afternoon and spent the entire time comparing the S-8800 to the Tecsun PL-880 and the Sony ICF-SW7600GR. I tested the radios on several shortwave bands and in both AM and SSB modes.

On Sunday, we discovered that mediumwave performance is lacking on the S-8800. Not so on shortwave! Check out this short video:

Click here to view on YouTube.

In my comparisons, the Tecsun S-8800 has consistently outperformed the PL-880 and Sony ICF-SW7600GR on the shortwave bands. The AGC is pretty stable and sounds much like that of the PL-880 when QSB (fading) is present. Sensitivity is better than the PL-880, though, so the S-8800 can dig those signals out of the noise a little better.

Note, too, I had to pick up both the PL-880 and ‘7600GR  in my hand to obtain the best performance–that additional grounding gave each a slight boost. Quite common for portables. The S-8800 didn’t require this.

After I returned home yesterday, it struck me that perhaps a longer telescopic whip gave the S-8800 an advantage. Turns out, it’s only three inches longer than the PL-880’s whip.

Next, I need to spend a little time with the S-8800 mapping out any birdies on HF–a tedious process. I hope to start on that today.

To follow updates on this yet-to-be-released receiver, follow the tag: Tecsun S-8800.

RadioShack franchises expand in wake of corporate bankruptcy

(Source: Twice.com via Tom Hacker)

RadioShack’s second bankruptcy in two years may have brought its company-owned stores to the edge of oblivion, but it has apparently sparked a renaissance among the chain’s approximately 425 independent franchisees.

As Wisconsin dealer-owner PJ Kruschel explains, inventory is beginning to flow again, and the departure of the corporate stores has ramped up customer demand and unshackled RadioShack dealers from restrictions on expansion.

Kruschel, who will grand-open the country’s first post-bankruptcy RadioShack tomorrow in Baraboo, Wis., shared his observations in an email to TWICE, which we posted below with his permission:

“I’ve owned a RadioShack dealer store for the past ten years and just opened a new store a couple weeks ago. It’s the first new RadioShack since the latest bankruptcy. There is another store opening in Utah and a couple more in Tennessee coming in the near future, but I’m the first.[…]

Thanks for the tip, Tom!

This is encouraging news indeed and verifies what I’ve seen at the two RadioShack franchises I’ve visited since the bankruptcy. In both cases, they are serving the needs of a local community–their inventory and services have always included products and services the corporate stores weren’t allowed to offer. RadioShack franchises have always had more freedom to expand their offerings, but now it appears they can even expand their locations. Excellent news, I say.

Dan shares solar eclipse spectrum files

(Source: The K2DLS blog)

Solar Eclipse Data Collection Project

Between 1600 – 2015 UTC on August 21, 2017, as the solar eclipse swept across the nation, I captured much of the lower 2 MHz of the radio frequency spectrum.  I used a Microtelecom Perseus SDR, a 130? inverted L with four radials, and lots of disk space.  In doing so, I have created a permanent record of this portion of the RF spectrum during the solar eclipse.

I am making the spectrum capture files available for your analysis and research.  Each file contains a 5 minute segment.  If you download a group of files, they will play in succession.

You can use the demo version of the Perseus software or any other software that can read the Perseus data, such as Linrad or HDSDR.  You cannot use just an audio player to play the files, even though they have .wav extentions.

Should you perform any analysis or otherwise make use of the files, I’d like to hear from you in the comments below.

Special thanks to Jav, K4JH, for donating the bandwidth for this effort.

Many thanks, Dan and Jav for making these files available for download! Someday, if I can find the bandwidth and space to upload them, I’ll also share the spectrum recordings I made.
