Hi Thomas

I see that Anon-co have the Tecsun PL-990 Ferrite rod aerial for sale. It even says in the product description “You can use it for your DIY projects.” I thought it might be of interest to your MW/AM radio constructors, especially if they can build a radio that receives more stations than the Tecsun using the same part!

Thanks for the tip, Gareth. This would indeed make it easy to construct an external MW antenna. Thank you for the tip!

FOR IMMEDIATE RELEASE

Apr 28, 2022

The Courtesy Program Committee (CPC) of the National Radio Club (NRC) and the International Radio Club of America (IRCA) is pleased to announce a special DX Test for distant listeners for WCGA on 1100 kHz in Woodbine, GA. The test is scheduled for 5/1/2022 at 12:00:00 AM Eastern Time (0400 UTC Sunday, May 1st).  This test is scheduled to run for 2 hours.

For WCGA, Wesley Cox, will be performing regular maintenance of the station’s audio chain and transmitter during the test. Listeners will hear: Morse Code IDs at 10 WPM at 800 Hz, Morse Code IDs at 20 WPM at 1000 Hz, Tone Sweeps, Long duration tones at 1 kHz, Off-hook Telephone Sounds, Voice IDs and more.

WCGA will be operating on a full daytime power of 10,000 watts during the test on their daytime antenna pattern.   This should aid DXers across the country and indeed the world in being able to receive this test!

RECEPTION REPORTS & QSL REQUESTS

WCGA is actively soliciting reports from DX’ers on their signal. They’re interested in hearing about frequency stability, audio quality, and overall performance. The station will accept both hard copy reports via USPS mail and email reports. They would love to receive audio recordings in either .WAV or.MP3 and videos in .MP4 video.

Reception reports should go directly to:

Wesley Cox

714 Narrow Way

St. Simons Island, Georgia 31522

wcganews@yahoo.com

Physical QSL card senders will receive a physical QSL. Email QSLs will receive email QSL.

Best audio narrative recording and received via email in MP3 or MP4 about themselves and their passion for radio that includes their reception of WCGA and the who, what, when, where, why and how of that event taking place will receive a special prize from the station. DX’ers who submit recordings must grant permission to broadcast their recordings. The decision of WCGA staff on the winner is final.

The IRCA/NRC CPC would like to thank the owners of WCGA, Wesley Cox, and Hall of Fame DXer, Jim Renfrew, for helping to arrange the test.

Good luck to all DXers!

About the CPC

The Courtesy Program Committee (CPC) is a cross-functional group comprised of members of both the National Radio Club (NRC) and International Radio Club of America (IRCA) for the purpose of coordinating and arranging DX Tests with AM radio stations.  These DX tests both allow radio stations to conduct valuable equipment tests on their transmitter and audio chain as well as enable DX hobbyists to receive the testing station from greater distances than would normally be possible.  The CPC membership consists of:  Chairman Les Rayburn, Paul Walker, George Santulli, Joe Miller and Loyd Van Horn.

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

In border radio’s early days, psychics and mystics ruled the airwaves (Mexico News Daily)

Charlatans originally built powerful ‘border blaster’ stations to evade scrutiny by US authorities

In radio’s early decades, among the oddball attractions found on the airwaves from 1920 to 1940 included a husband-and-wife team of psychics broadcasting from the U.S.-Mexico border under the stage names of Koran and Rose Dawn who became so popular that their extensive following helped them create a secondary income source: an organization called The Mayan Order.

Those who applied for membership and received its periodicals, the founders suggested, could harness the ancient Mesoamerican civilization’s secrets.

The pair were just two of the many psychics and other broadcasters of questionable integrity on the airwaves along the Rio Grande during radio’s beginnings. These characters built “border-blaster” stations of such epic size and scope that they could transmit from the Mexican side of the border into the United States.

Author John Benedict Buescher’s new book, Radio Psychics: Mind Reading and Fortune Telling in American Broadcasting, 1920–1940, unearths Koran and Rose Dawn’s forgotten story, as well as those of about 25 other border-blaster radio personalities on the Rio Grande who were heirs to a longtime American fascination with the occult.

“I was surprised how really dominant this stuff was in the early days of radio,” Buescher said. “Radio historians typically have just waved it off, not really focused on it, didn’t really take it seriously.” [Continue reading…]

Why Well-Dressed Towers May Wear Flared Skirts (Radio World)

Cox, Dawson explore the benefits of umbrella-spoke feed for MW towers

Ben Dawson and Bobby Cox will talk about flared skirts at the NAB Show.

“A flared skirt is a set of symmetrically spaced cables around the tower, which attach electrically near the top of the tower, extend outward from the tower along a path similar to the top guy cables, and then turn back in toward the tower base at a point roughly halfway down the tower,” said Cox, senior staff engineer at Kintronic Labs.

“Insulators at this midpoint insulate the cables from ground. The cables terminate on an insulated feed ring encircling the tower base above ground level, similarly to a conventional skirt feed. The antenna is driven between this feed ring and RF ground. The resulting flared skirt takes the shape of a diamond, looking rather like umbrella spokes.”

These systems are used to provide a feed arrangement for grounded towers that is mechanically simple but has certain attractive aspects.

“The wide bandwidth characteristics of the flared skirt make these antenna designs extremely useful for multiplexing several AM stations onto a common antenna,” said Dawson, consultant engineer at Hatfield & Dawson. [Continue reading…]

Palau restores AM radio service (RNZ)

After erecting a new tower Palau’s state broadcaster has restored its AM radio service.

The previous AM tower was destroyed during Typhoon Bopha, in 2012.

Rondy Ronny, head of programming said that the new AM tower and radio service will benefit all the 16 states of Palau.

“A lot of the outlying states are not able to connect into the internet and just don’t have that capability or have very high tech phones like how we do here in Koror. People don’t expect people from Angaur, from Babeldaob to be on their phones all the time.”

Ronny said that the new tower will be crucial to Palauans during natural disasters. [Continue reading at RNZ…]

Frans experiments with the MFJ-1026 Noise Canceling Signal Enhancer

25 Replies

Many thanks to SWLing Post contributor, Frans Goddijn, who writes:

“Last week I purchased the MFJ-1026 ‘noise canceling signal enhancer’ and I posted two blogs with video about it. Initially the device seemed as useless as it is good looking but then I found a configuration where the device is not only pleasant to have but also useful for radio listening.”

Here are Frans’ reports which he kindly shares from these two posts originally published on his blog, Kostverlorenvaart:

Part 1: MFJ-1026 deluxe noise canceling signal enhancer

Using a GRAHN antenna, (a VENHORST wire antenna for noise reference), the iCOM R8600 radio and optional bhi DSP audio noise canceling, trying to see what’s the best way to cancel noise — on the antenna entry point of the radio or at the speaker output end.

In this case the MFJ-1026 seems ineffective. The DSP at the audio output end works well and easy.

I have also tried two GRAHN antennas on the MFJ-1026, one for MAIN and one for AUX but that was also not noticeably effective yet.

I will also try the little whip antenna that MFJ supplied with the box. Further tweaking may turn out to be helpful on some other frequencies / signals.

Before installing the MFJ i used the little TECSUN H-501x to scan the room for any devices producing radio noise. It turned out that the two Apple Homepods sit in a dense cloud of radio noise, the Macbook Pro also radiates noise, EVE smart plugs controlling lights also produce radio noise, two little label printers s well and the HP printer/scanner too. So I moved those to the other end of the toom or to another room. Continue reading →

Trends in Tropical Bands Broadcasting (EDXC)

EDXC co-founder Anker Petersen has published the latest Trends in tropical bands broadcasting and Domestic Broadcasting Survey.

Anker writes: “Since the Danish Short Wave Club International published the first annual Tropical Bands Survey in 1973, I have registered which stations are active, based upon loggings from our members and other DXers around the world. Here is an updated status outside Europe and North America, where Clandestine and Pirate stations are not included.”

Both of the documents are available at the DSWCI website, to study and enjoy. Click on the two blue boxes on the left side of the website for the current versions, and also to look back over previous versions. Hopefully, these will also encourage more DXers to listen regularly to the Tropical Bands. [Click here to read the original post…]

Universal Power-Up Time For AMs Seen As One Potential Fix For Proposed Clock Change. (Inside Radio)

Talk in Washington about making Daylight Saving Time permanent may bring cheers from people who hate the “spring forward” and “fall back” disruption to their body clocks. But it has the potential to upend radio stations, especially during the darkest winter months. New Jersey Broadcasters Association President Paul Rotella is urging the bill’s sponsor to consider adding some protections for AM radio into the bill.

“If this legislation is adopted, many if not most, AM stations will lose an hour of morning drive with no or reduced power and no one seems to be addressing the issue,” said Rotella in a letter to Rep. Frank Pallone (D-NJ), the chair of the House Energy and Commerce Committee. Permanent daylight-saving time would mean that AM daytime-only stations and AMs with directional signals would not be at full power until after 9am in some parts of the country.

Rotella says such a move would mean that these stations would lose most of their critical morning drive daypart when a lot of ad revenue is made. The upside is the change would give AMs more time during their afternoon drive, when some stations need to power down before 5pm during the winter months. But many AM owners have said that the amount of money they would make from an extra hour of broadcast time during the afternoon would not make up for the losses they would suffer in the morning.

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’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Is radio in a second golden age? Here’s what the first looked like. (MSN / Washington Post)

On. Oct. 30, 1938, America was rocked by shocking news: Aliens had been spotted crash-landing outside Grover’s Mill, N.J. Additional sightings were soon made across the Northeast, including reports of Martians unleashing poisonous gas on Manhattan and burning onlookers alive with ray guns. Periodically, the breathless news reports would be reduced to static.

Listeners reacted in real time; many of them flooded the streets wearing gas masks and wet towels over their faces. Stores were raided, bridges and expressways were inundated with traffic, and pregnant women reportedly went into early labor.

Of course, the alien invasion never actually happened. The news bulletins were part of a live Halloween program a young producer and a cast of talented actors were presenting over the radio. The producer was 23-year-old Orson Welles, and the name of the episode was “War of the Worlds.” The H.G. Wells-adapted story had been produced for radio as part of Welles’s regular Sunday night broadcast, “The Mercury Theater on the Air” — a program that had hitherto been largely ignored, as it was up against a wildly popular variety show starring comedians Edgar Bergen and Charlie McCarthy.

Only this Sunday was different, as millions of Americans who had tuned in to listen to Bergen and McCarthy changed their dials when the duo introduced a guest opera singer. “No one was in the mood for opera that night, and much of the country stumbled onto Welles’s broadcast by mistake, not knowing the news bulletins they heard were part of a radio drama,” explained Carl Amari, a syndicated radio host and the founder of Radio Spirits, a large distributor of classic radio programs.

The Kremlin tries to stifle Radio Free Europe — and its audience surges (Washington Post)

As the U.S.-funded broadcaster is forced to shut most of its Russian operations, its Web traffic indicates that Russian people are eagerly consuming its stories

Radio Free Europe, the U.S.-funded operation that got its start by piping American-flavored news through the Iron Curtain in 1950, could see big trouble brewing for its Russian operation in recent years.

The Kremlin kept putting the screws to its Russian-language broadcasts, throwing up ever more regulatory hurdles. But it was in late 2020 that the hammer really came down. The “media regulator” demanded that every broadcast, digital story and video carry an intrusive disclaimer at the top stating that what followed was the product of a foreign agent.

“Basically, it was like telling our audience to go away,” said Jamie Fly, the CEO of Radio Free Europe/Radio Liberty, as the organization has been known since a 1976 merger.

That labeling would interfere with the private nonprofit’s mission at a core level. So, Fly told me, “we refused to comply.” [Continue reading…note that this content might be behind a paywall for some readers.]

New radio station helps Ukrainian refugees adapt in Prague (AP)

PRAGUE (AP) — This is Radio Ukraine calling.

A new Prague-based internet radio station has started to broadcast news, information and music tailored to the day-to-day concerns of some 300,000 Ukrainian refugees who have arrived in the Czech Republic since Russia launched its military assault against Ukraine.

In a studio at the heart of the Czech capital, radio veterans work together with absolute beginners to provide the refugees with what they need to know to settle as smoothly as possible in a new country. Continue reading →
