Radio Waves: First Microprocessors, Ocean FM, SWL Interviews, and NPR’s take on All-Digital AM

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Marty, Martin Butera, and the Radio Survivor for the following tips:

The Surprising Story of the First Microprocessors (IEEE Spectrum)

Transistors, the electronic amplifiers and switches found at the heart of everything from pocket radios to warehouse-size supercomputers, were invented in 1947. Early devices were of a type called bipolar transistors, which are still in use. By the 1960s, engineers had figured out how to combine multiple bipolar transistors into single integrated circuits. But because of the complex structure of these transistors, an integrated circuit could contain only a small number of them. So although a minicomputer built from bipolar integrated circuits was much smaller than earlier computers, it still required multiple boards with hundreds of chips.[]

Ocean FM Was Fire: How Local Radio Done Right Can Heat A Cabin | Radio Schmaltz (Part-Time Audiofile)

[…]The cabin on a rocky peninsula in Northwest Ireland might not have had all the letters for its Scrabble set or a microwave, but it did have another marvel of 20th century technology. It was a little CB/AM/FM radio crouching behind a box of matches on top of a kitchen cabinet.

I decided to put the switch on FM and started swirling the dial. As soon as I heard a lilting woman’s voice underneath a sheet of static, I began carrying it around the tiny room while adjusting the rabbit ears.

Now the signal was as clear as the peat-rich water was brown, a farmer was being interviewed about the economic downturn. It was a quick piece — just some brogue-ish assurances that one doesn’t choose agriculture for an easy life. Then came a trio playing an Irish ballad, and then came North West Hospice Bingo: a bingo game that allows listeners from across the broadcast range of Ocean FM’s two regional frequencies to play bingo, including the residents of the hospice.

I’d bundle up for walks outside where the wind was loud, blustery, and sacred. The ocean crashed against the rocks in a way I never conceived as being real outside of movies. But when I was inside, the radio might as well have been a Soviet relic with only a volume control and no tuner because I simply couldn’t touch that dial. I learned the schedule quickly, timing walks and firewood runs so that I’d be back in time for Country Jamboree, a boy-girl-boy-girl style line-up of Irish and American country tunes.

As I’d stand by the wood-stove, taking off my cold wet socks to put on the toasted, at time singed socks that I’d been roasting, I felt the fulfillment of the promise of radio. I could hear Fessenden making history with the first radio broadcast of music, Oh Holy Night transmitted on a rocky coast on Christmas Eve of 1906 and heard by ships at sea.[]

Coffee and Radio Listen

Coffee and Radio Listen is an investigation of Brazilian radio listener, by Martin Butera.

How they began listening to radio, the local or international stations that influenced them, the interests they have when tuning to a station, the languages they like to listen to, if they send listeners reports and collect QSLs, their antennas and receivers, and all aspects related to the radio listen both in shortwave and in other bands and modes.

Each month they will have in this blog, an exclusive interview with a Brazilian radio listen. At the end of this project, a free downloadable e-book will be available, which contains all the interviews and statistical references.

Every month there will be a new interview, this month of March launch month we start with 2 interviews

Martin is Argentinian, born in the city of Buenos Aires capital. He currently lives in Brasília DF, capital of Brazil. He is also a journalist, documentary maker and founding member of Radio Atomika 106.1 MHz (Buenos Aires, Argentina).

NPR Supports All-Digital on AM, With Caveats (Radio World)

National Public Radio “generally supports” allowing stations to transition, if they wish, to all-digital AM transmission using HD Radio in the United States. But it believes the commission needs to go further on how it would handle interference complaints from neighboring analog stations in the band.

About 80 AM public radio stations are affiliated with NPR or receive operational funding from the Corporation for Public Broadcasting, including WNYC(AM) in New York City.

NPR says it has significant interest in any measures to help AM broadcasters better serve the public by improving the listening experience.

“Facilitating the expansion of HD Radio and its additional functionality for program and public safety information and services would serve the public interest, provided the transition to all-digital HD Radio operation does not cause harmful interference,” NPR wrote in comments filed with the FCC this week.

“As it has in the past, NPR supports the expansion of HD Radio, but not at the expense of current analog AM service.”[…]

Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

WNPV Radio preparing to go off air April 30 (The Reporter)

TOWAMENCIN — When April ends, the airwaves above the North Penn valley region will be emptier, and so will a little brick building on Snyder Road in Towamencin.

Sitting below five 165-foot-tall radio antennas and one cell tower, that brick building has been the home for six decades of WNPV, the local radio station found at 1440 AM and 98.5 FM.

“We’ve been at it for 60 years, and our mission and our core values are really no different today than they were in October of 1960. It literally is to serve the community,” said Phil Hunt, the station’s General Manager.

“It’s gotten to the point where it’s not sustainable for us to continue to do that. It takes resources to do it properly; those resources, primarily, are people, and we were having trouble making ends meet,” he said.

Hunt announced Wednesday that WNPV will go off the air on April 30, bringing an end to an era of live, local news that began on Oct. 17, 1960. The station’s coverage of local sports, politics, breaking news, and key issues have earned dozens of awards, a handful of which greet visitors as you walk past an old teletype machine through the station’s front door.[]

Privat-ear Subminiature Tube Pocket Radio (JamesButters.com)

The Privat-ear pocket radio was manufactured in the USA and released onto the market by Electronics Systems Corporation in 1949 (1a, b, c). Although small enough to fit in a shirt pocket this is not a transistor radio; it owes its small size to the use of subminiature tubes developed during WWII and was designed as an earphone only model. It predates the first commercially available transistor radio by five years and was an innovative, but ultimately doomed, attempt at realizing an American cultural objective; the creation of a portable shirt pocket radio with mass appeal.

The Privat-ear was invented by Frank L Stuck, a Minister of Lakeland Florida. Born in Washington, Pennsylvania on October 13 1904 to William and Maise Stuck, he was the second youngest of four children (1d, e). He studied Theology at Bethany College, West Virginia from 1924 – 1927 and received a Doctor of Divinity degree from the American Theological Seminary at Wilmington Delaware (1f). Whilst attending College he was one of the founding members of Alpha Pi Alpha, was a member of the Student Volunteers and met and married Iva Myrtle Driggs.[]

IN CASE YOU MISSED IT – The End Of Radio. Really? (Radio Ink)

(By Mike Bustell) I try to keep my head down and quietly work behind the scenes helping our salespeople make a killing for our advertisers and our company. However, I had to react to Roger Lanctot’s “Technology Tyranny and the End of Radio” LinkedIn article published in last Friday’s Radio Ink headlines.

How Tesla and Silicon Valley (and other tech giants) feel about local radio is not much different than what our salespeople hear when talking with their local garden center or auto dealer group — that local radio is no longer relevant to bother putting it on their 2020 dashboards.

All these objections are happy opportunities to educate, bond, and sway hearts, minds, and advertising budgets. We have to be happy well-armed warriors with targeted customer-specific information every time we ask for a decision-maker’s valuable time. Once we earn an advertiser’s business we can never stop educating, bonding, or working on helping them grow their business.

Below is the most up-to-date look at the audio sources that $100K+HHI purchasers and lessees for new hybrid and electric vehicles are using. Like Mike Bloomberg taking the salt shakers off of New York City restaurants’ tables, Tesla’s removing easy access to local AM/FM radio stations on their new vehicles’ dashboards shows a similar out-of-touch-with-the-people attitude. Ninety-four and a half percent of $100K+ Age 25+ adults who plan to buy or lease a new hybrid or electric vehicle in 2020 listen to Local AM/FM radio every week — nearly three times that of Spotify, the second most-listened-to audio source every week used by these consumers.[]

China COVID-19 shut-in tunes in to the world via radio (Marketplace)

The battle to contain the COVID-19 virus in China has kept most people at home since the end of January.

Life is slowly returning to streets in cities like Shanghai, but face masks are now required in nearly all public spaces, even though they are not recommended for the general public by the Centers for Disease Control or World Health Organization.

Since there is a shortage of masks, most people are still effectively forced to stay home. As Marketplace’s China correspondent, this includes me. My window to the world for a better part of a month has been through radio.[]

Tecsun PL-990: How to distinguish pilot run and final export versions

The Tecsun PL-990

As I suspected, it appears the Tecsun PL-990 batch that showed up recently on AliExpress for $399 each are the preliminary pilot run units that Tecsun offered in China last year. The final export version of the PL-990 is not ready for production yet and has been severely delayed by Covid-19 quarantines.

Anna at Anon-Co reports that Tecsun factories have been closed since mid-January 2020 and have only recently recommenced production, “but at a very slow pace.”

Since there will eventually be two different versions of the Tecsun PL-990 in the wild–the pilot run for China, and the finalized export version–I thought I’d share a trick Anna has described to tell the difference between the two.

Anna notes:

One way to easily see this is from the labels for the buttons above the keypad, these should be

[ TIME ], [ TIMER A ], and [ TIMER B ] (see picture below)

Tecsun PL-990 Final Export Version:

Tecsun PL-990 Final Export version

Tecsun PL-990 Final Export Version

Pilot Tecsun PL-990 (preliminary China domestic version):

Preliminary Pilot Tecsun PL-990 distributed in China — image from AliExpress.

Anna adds:

I highly recommend [no one] buy these pilot versions, because the software on those devices is also not developed.

There still isn’t a final version or any price indication available yet, but it will definitely not be US$399.99.

So in case it’s not clear: don’t purchase a PL-990 until you can confirm you’re receiving a final export version which has the TIME, TIMER A, and TIMER B labels.

Again, at time of posting, the final PL-990 export version is not yet in production.

When the final export PL-990 is available, I will announce it here on the SWLing Post with links to authorized retailers like Anon-Co.

Free to a good home: A Vintage Grundig Satellit 600 Professional

I was recently contacted by Allan Rosenbluth, a particularly generous SWLing Post reader.

Allan contacted me because he would like to give away his cosmetically excellent Grundig Satellit 600 Professional (see photo above) with all the original paperwork. He said that the radio turns on, but does not work or produce sound.  Allan purchased this radio for his father who has sadly passed away.

I would assume the 600 might need to be re-capped, or it might only need a little DeOxit on some of the contacts.

We’re not looking for someone to fix the 600 and flip it on eBay, we would simply like his dad’s Satellit 600 Pro to find a good home.

Allan is not interested in the hassle of shipping this radio–he only want to arrange a local pickup.

If you live near Encino, CA (91436) and are interested, simply contact Allan via his email address.

Thanks again, Allan!
