DX Central SEDAP: A Sporadic Es Data Analysis Dashboard

Many thanks to SWLing Post contributor, Loyd Van Horn, who shares the following announcement:

FOR IMMEDIATE RELEASE

DX Central Unveils SEDAP: The World’s Most Advanced Sporadic Es Data Analysis Dashboard for the FM DX Community

MANDEVILLE, La. — April 29, 2026 — DX Central is proud to announce the official launch of version 2.0 of our popular Sporadic Es Data Analysis Project (SEDAP), a revolutionary, interactive intelligence dashboard designed to decode the mysteries of VHF propagation. Officially unlocking on Friday, May 1, 2026, at 7:45 PM CDT (0045 UTC May 2) at fmdxdata.com, SEDAP transforms nearly a decade of siloed radio loggings into a massive, cinematic data science suite, completely free of charge for the hobbyist and academic community.

Historically, analyzing Sporadic E (Es) propagation on the FM band has been an isolated effort, with individual DXers tracking their own localized season-over-season metrics and comparing notes with other DXers. SEDAP shatters that limitation by aggregating more than 95,000 North American FM broadcast logs and presenting them with brand new interactive visualizations to give DXers a whole new understanding of this elusive and magical propagation method.

“For years, our understanding of Sporadic E has been largely limited to individual observations,” said Loyd Van Horn, founder of DX Central and creator of SEDAP. “By bringing all of this data together, we aren’t just looking at spreadsheets anymore. SEDAP allows us to physically watch ionospheric clouds spawn, compress, and track across the continent in real-time. We can finally see what a typical season looks like on a macroscopic level.”

Built on a Google Cloud BigQuery architecture, SEDAP boasts a sleek user interface featuring dynamic visualizations, including:

  • The Es-Cloud Tracker: The newest and perhaps most exciting addition to the SEDAP dashboard. The Es-Cloud Tracker is a cinematic, multi-day playback engine that maps the approximate geographic formation location of FM DX Sporadic Es ionization clouds over North America. Openings can be “played” on a timelapse, allowing DXers to watch a simulation of the Es clouds as they develop, morph and transit throughout the day or a range of days.
  • Path Line Analysis: In-depth analysis on the most common and productive paths to and from a DXer or station location. Visually “see” the paths that evolved over the span of a day or date range.
  • Frequency & MUF Forensics: An interactive “SDR Tuner” interface to interrogate large scale band yields, signal paths, and daily Maximum Usable Frequency (MUF) ceilings.
  • Station & RDS Intelligence: Deep-dive forensics into the WTFDA station database, featuring PI-Code adoption maps, format/slogan correlation matrices, and gamified “Unheard Target” lists for US States and Counties.
  • DXer Network Intelligence: Long-term seasonal performance audits and multiple normalized metrics to filter out observer bias as much as possible
  • “We have certainly seen a huge growth in the number of DXers both reporting receptions and the amount of receptions they are reporting thanks to improved technology and resources from SDRs to propagation monitoring through Rabbitears and the FM DX Webservers,” says Van Horn. “So while we are not here to say one season was better than another, we can give DXers insights into Sporadic Es season that can help them strategize antenna placement and bearing, timing of monitoring, potential paths based on different periods within the season and a whole lot more. This is about improving our understanding of what happens when the ionosphere sends those FM signals back down to Earth.”

SEDAP makes no claim of ownership over the raw data presented, acting strictly as an analytical engine. The platform owes its immense capabilities to the unprecedented collaboration and public data provided by FMList.org, and the Worldwide TV-FM DX Association (WTFDA).

To protect the integrity of the database and respect the bandwidth of its data partners, SEDAP is strictly governed by a non-commercial usage policy. Automated scraping and commercial monetization are prohibited, but users are highly encouraged to explore, share, and cite the dashboard’s findings.

The Sporadic Es Data Analysis Project will be accessible to the public beginning May 1, 2026. To access the dashboard, view the real-time launch countdown, or read the full data usage policy, visit fmdxdata.com.

About DX Central: Based in Mandeville, Louisiana, DX Central is a premier hub for the radio monitoring community, dedicated to advancing the hobby of DXing through live streams, online receivers, regular DX challenges and contests, educational content, and data-driven propagation analysis.

Mark shares some sights and sounds from South Korea

Many thanks to SWLing Post contributor Mark Hirst, who recently returned from a trip to South Korea and, at my request, is sharing some sights and sounds with us. Mark writes:

Thomas,

I’ve been catching up on cataloguing pictures and videos from my Korea trip.

I’ve enclosed a picture taken through the Seoul North Tower observation window of an adjacent radio mast.

You can also see a view of Seoul along with its dubious air quality !

I’ve posted these radio-related YouTube videos:

Thank you, Mark! Wow–I can’t imagine being a guest in a capsule hotel during a fire–that sounds terrifying. And thank you for that photo of the Seoul North Tower–great shot!

End of an Era: CBS News Radio Shuttering After 100 Years

Edward R. Murrow

Many thanks to SWLing Post contributor Richard Cuff, who shares the following article from The Guardian regarding a significant restructuring at CBS News. In a move described by editor-in-chief Bari Weiss as a “necessary decision” driven by a radical shift in the media landscape, the network has announced a major round of layoffs affecting roughly 6% of its staff. Most notably for the radio community, the nearly 100-year-old CBS News Radio service is set to shutter on May 22, 2026. This marks the end of an era for a service that famously hosted Edward R. Murrow’s wartime reports and produced the CBS World News Roundup, the longest-running newscast in the country.

The Deepelec DP-666: A very interesting radio

By Jock Elliott, KB2GOM

My friend Andy, who is an expert medium wave DXer, calls it his “weapon of choice” and a “DX machine.” In fact, just a night ago, using a YouLoop passive antenna hanging from a birdfeeder on his porch in upstate New York, he snagged a couple of tiny Mexican stations above 1600 kHz at a distance of over 2000 miles. He was surprised the stations were there, and it was a bit of a hunt on the internet to find their livestreams and ID them.

The radio that made hearing these diminutive stations possible is the Deepelec DP-666, a radio based on the high-sensitivity, high-selectivity TEF6686 chip which is used in automotive radios. The DP-666 measures 5 inches wide (excluding knobs) by 3 1/8 inches high by 1 1/8 inch deep. On the front panel are a speaker grill, a 2.8-inch color display, and 15 buttons for various radio functions (including a full numeric keypad for direct frequency entry) and a red power button. On the right side are tuning and volume knobs. On the bottom panel is a master switch for power. On the left panel are a 1/8-inch headphone socket and a USB-C port for a communication interface and for charging the 5000 mAh rechargeable battery, which is not user-accessible.

The DP-666 can receive FM (from 65-108 MHz with various frequency ranges selectable for different parts of the world and over a dozen different bandwidths), SW (from 1700-27000 kHz), MW (522-1791 kHz, 9 kHz steps; 520-1720 kHz, 10 kHz steps) and LW 144-513 kHz. In AM mode, 3/4/6/8 kHz bandwidths are available. The DP-666 does not offer single-sideband reception.

You won’t hear anything, however, unless you connect an antenna to the standard SMA female connector on the top panel of the radio, because the DP-666 has no internal antenna. The DP-666 comes with a 29 ½ inch whip antenna that does a yeoman job of receiving MW and FM. For MW DXing, Andy prefers the passive YouLoop, and he uses the DP-666/YouLoop combo frequently. “It’s quiet,” he says.

For MW reception, I like a direct cable connection between the DP-666 and a Terk AM Advantage, which is an un-amplified loop antenna with capacitive tuning. I can hold the Terk antenna in my left hand (which allows me to rotate it from side to side and even tilt it for improved reception), and with my thumb, I can rotate the antenna’s tuning wheel for peak reception. At the same time, I hold the DP-666 in my right hand and operate the tuning knob with my thumb and forefinger. It looks a little weird, but works really well.

For FM reception, I use a scanner antenna, a Comet W100RX extended to about 31 inches. The DP-666 display offers a full complement of RDS information if transmitted by the FM station. I am not, by any means, an expert FM DXer, but it seems to be a “hot” receiver.

For SW reception, the DP-666 also works pretty well with the whip antenna that comes with it. When connected to my 50-foot indoor horizontal room loop antenna, it detected a lot of shortwave stations on auto-scan. My guess is that dedicated shortwave DXers will be pleased with this pocket-sized radio.

In addition to its excellent electrical performance on MW, SW, and FM (I did not test LW), there are a couple of things about the DP-666 that I really love. The first is that, straight out of the box, the DP-666 is easy to use without consulting the manual. However, if you want tons, and tons, and TONS of customizability, press and hold the MODE button to access the MENU screens, where you can “fiddle the bits” to your heart’s delight. I have never used any of these settings, but they are there if you want them. (I think I consulted the manual just once to learn how to store stations in memory.) The well-written manual can be downloaded in PDF format here: https://deepelec.com/files/dp-666/DP-666_Product_Manual_EN.pdf .

The second thing that delights me about the DP-666 is that it is a quiet radio to operate. The clicks from the buttons are soft, and the tuning knob has detents that are felt, not heard. With headphones on, I can seek distant stations without disturbing others in the room.

Bottom line, the Deepelec DP-666 is a sensitive and easy to use radio that delivers pleasing results on MW, SW, and FM. I would be delighted to hear from others who have used it, particularly with high-performance antennas.

New Radio Station Breaks the Silence from Gaza Ruins (SAFA News Agency)

From the rubble of a territory that has endured years of siege and devastation, a new independent radio station has begun broadcasting once again, offering a voice to residents after a prolonged blackout of local media. For the first time in over two years, Palestinians in the Gaza Strip can tune in to Hona Ghazza, meaning Here Gaza, on FM radio, a milestone in communication after all 23 local stations were destroyed during Israel’s genocidal war.

Broadcasting from makeshift studios and supported by collaborations between local media groups and university centres, the station is designed to serve as more than just a source of music or news. [Continue reading…]
