A recap of the 2015 Winter SWL Fest

The following article originally appeared in the April 2015 issue of The Spectrum Monitor magazine.

Every year, I attend two great radio conventions: the Dayton Hamvention and the Winter SWL Fest. While the Dayton Hamvention draws a massive crowd of ham radio operators, vendors, and makers from across the planet–and it’s truly a fun and fantastic event–the smaller Winter SWL Fest is actually my fave of the two.

Any why is this? A re-cap of the 2015 Winter SWL Fest might provide some clues.

The Winter SWL Fest is organized and sponsored by the North American Shortwave Association (NASWA) and each year draws well over 100 radio enthusiasts to Plymouth Meeting, Pennsylvania. While it is a shortwave radio festival––with its roots firmly in the shortwave medium––it’s certainly not limited to the HF bands only; in fact, here’s a list of some of the forums from 2015, and their subject breadth is remarkable:

  • Radio on the Road 3. Janice Laws shared radio recordings and videos from her various travels across the planet, showcasing the local flavor found on the FM and AM dials.
  • The Year in Pirate Radio. George Zeller once again hosted the shortwave pirate radio forum, covering the year in pirate radio, and announcing inductees into the PIrate Radio Hall of Fame.
  • Time Travel, Teleportation, and Spectrum Hoarding for the Contemporary DXer. My good friend Mark Fahey and I co-hosted this forum. In this forum we discussed our obsession with collecting and sharing spectrum recordings, highlighting the added context spectrum playback provides that traditional broadcast recordings cannot. We brought along several terabytes of spectrum recordings from my home in North Carolina and from Mark’s home near Sydney, Australia, to share with this forum’s attendees.
  • Coast to Coast: Geographically Enhanced Mediumwave Reception. Bill Whitacre shared what he has learned from mediumwave DXpeditions to Grayland, WA, and Lubec, ME, over the past 5 years. Bill focused on the advantages of carefully-selected geographic locations for the best DX opportunities.
  • Ultralight Mediumwave DXing. Gary Donnelly hosted a forum which touted the virtues of the most simple radios and receivers and the immense fun that can be had from them. Gary discussed some amazing reception records obtained with these pocket-sized “ultralight” (and ultra cheap!) receivers.
  • Crisis Radio. Michael Pool (a.k.a., “The Radio Professor”) focused on radio as it sounds locally during crises. He shared recordings and airchecks he had captured during natural disasters, terrorist attacks, and moments of civil unrest. Through these recordings, and with the advantage of some emotional distance, attendees could form their own opinions as to how the media handled each event.
  • Radio and Today’s Teenagers. Anthony Messina (age 18) focused his forum on the way teens view radio today, taking into account the medium’s ongoing evolution. Anthony also discussed how he got interested in shortwave radio and DX’ing in the age of internet and smartphones––a remarkably fascinating (and familiar) journey.
  • Kickin’ It Old School: A Return to Regenerative Receivers. In this forum, Skip Arey proposed that a radio design, at the very roots of RF Technology, is experiencing a resurgence: regenerative receivers. He discussed the classic regen circuit and how to use it to bring a new dimension to shortwave listening.
  • The View from Europe. Finn DXer Risto Vahakainu, who travels to the Winter SWL Fest with a contingent of Finnish DXers, reported on the state of the radio hobby in Europe and specifically in Finland. He focused upon the impact of SDRs and also described remote DX sites one can rent for one’s own DXpedition in northern Finland.
  • “UFOs, Gliders and Planes, Oh My!” Tom Swisher––noted member of the SWL Fest so-called “scanner scum”––covered the wide array of frequencies that can be monitored with “your trusty old scanner” after local law enforcement goes digital.
  • Monitoring Dusty War Zones and Tropical Paradises: On Being a Broadcast Anthropologist. Mark Fahey––who travelled from Australia to attend the Winter SWL Fest for the second year in a row––presented a tour of his monitoring station (i.e., his house). We saw how Mark combines several satellite, internet, and SDR feeds from across the globe to create a custom video and audio listening post with feeds. Mark, who is also an avid traveler, shared some of his highly original, out-of-the-box ways of collecting rare radio DX.
  • The Keeping of Time. In this forum, Mark Phillips discussed the importance of accurate time-keeping as our hobby moves toward the digital realm. Mark explained the difference between time sources, why they are different, and why accurate time is so important.
  • Recognizing Digital HF Signals: Eyes and Ears. TSM contributor Michael Chace-Ortiz taught that simply with one’s eyes and ears, it’s possible to identify a number of the digital modes and anomalies on our HF bands. Mike gave an interactive audio-visual tour of numerous modem signals, Over-The-Horizon RADARs, ionospheric sounders, ocean sensing systems, and various other digital oddities that can be heard today.

In short: what a dynamic––and diverse––forum line-up!

Of course, for the second year in a row, David Goren’s annual Shortwave Shindig was broadcast live from the Fest via WRMI. It was great fun receiving live reports from listeners across the globe.

I’m sure some twenty-eight years ago when the first SWL Fest was held, forum topics all centered around the shortwave radio hobby fairly exclusively. But today, how we define radio has changed, and the shortwave radio is no longer the only way to glean accessible content from across the globe. Most of the SWL Fest attendees and hosts, however, maintain and cultivate the spirit of DXing: finding innumerable paths into an ocean of diverse broadcasting. I was happy to be a part of the shortwave radio-related forums that centered on the use of software-defined radios, no doubt a revolutionary game-changer in our listening hobby, and a technology I actively explore (see my review of the TitanSDR next month).

While the 2015 line-up was diverse and drew on the expertise of some of the most noted enthusiasts in our field, this experience is actually what I’ve come to expect from the SWL Fest. So many amazing projects, including a Sundance award-winning film (!), have played a part in making the Fest what it is today.

I encourage you to keep tabs on the Winter SWL Fest and make plans to attend in 2016. Details will be posted on the Winter SWL Fest website: https://swling.com/blog. One thing is for sure: if the crazy winter weather conditions this year didn’t stop me from driving several hundred miles through snow and ice to the Fest, nothing is going to stop me next year! Hope to see you there.

A parting note

Martin-Peck-2

As you may imagine, since the SWL Fest has been ongoing for many years, strong bonds have formed among Fest attendees––indeed, the group has become like an extended family. This year, we learned during the annual Saturday night banquet that we had just lost one of our Fest family, one Martin Peck, following a battle with esophageal cancer. Marty, as we all knew him, was an incredibly kind fellow, well-loved and warmly regarded at the Fest. He was not only an avid SWL, but a talented musician, and a member of the New Westchester Symphony Orchestra. Marty could play some of the most obscure interval signals on demand with practically any wind instrument. He found a welcome home at David Goren’s Shortwave Shindig.

Marty, pal, we’re going to miss you.

How I Discovered Shortwave Radio

BoysBookOfRadioI discovered shortwave radio almost by accident.

I had built a simple crystal radio from plans in a library book…(I think it was “The Boy’s Book of Radio” or similar. ) I added a one transistor amplifier later. I had a really great long wire antenna from the garage to the house, up about 30 feet, about 75 feet long, and a good earth ground.

I was playing around with it, and I had an old phonograph amplifier I connected to the output of it. I de-tuned the coil and apparently managed to get it tuned into the 49 meter band. All of a sudden I was hearing broadcasters from Europe. Some were in English, others in foreign languages.CrystalRadio

Up to that point I had thought that all radio was like AM broadcast, only good for a few hundred miles even at night. I was flabbergasted. That marked the beginning of my addiction to radio. I have never gotten over the miracle of HF radio ever since.


Many thanks, Greg, for sharing your memories with us!

I can only imagine the thrill is must have been to tune in stations from across the planet on your simple, home-brew radio set.

I encourage other SWLing Post readers and contributors to submit their own listener post!  Tell us how you became interested in radio!

When WLW was the one and only “Super Station”

For a Brief Time in the 1930s, Radio Station WLW in Ohio Became America’s One and Only “Super Station”

by Katy June-Friesen

When President Franklin Roosevelt, sitting in the White House, pushed a ceremonial button on his desk in May 1934, a five hundred thousand-watt (500 kW) behemoth stirred in a field outside Cincinnati. Rows of five-foot glass tubes warmed. Water flowed around them at more than six hundred gallons per minute. Dozens of engineers lit filaments and flipped switches, and, within the hour, enough power to supply a town of one hundred thousand coursed through an 831-foot tower.

Thus began WLW’s five-year, twenty-four-hour-a-day experiment: a radio station that used more power and transmitted more miles than any station in the United States had or would. The so-called super station—licensed by the new Federal Communications Commission (FCC) on a temporary basis—amped up the debate among broadcasters, government regulators, and listeners about how radio should be delivered to serve the “public interest,” a mandate laid out in the Radio Act of 1927, and influenced legal, programming, and technical decisions that shape the broadcast system we know today.

Since radio’s beginnings in the early 1920s, industry and government leaders promoted it as the great homogenizer, a cultural uplift project that could, among other things, help modernize and acculturate rural areas. The challenge was how to reach these areas, many of which received few or no radio signals in the mid-1930s. One solution was high-powered, clear-channel stations that could blanket large swaths of the country with a strong signal. These stations operated on “cleared” frequencies that the government assigned to only one station to prevent interference.

WLW had operated on one of forty designated clear channels since 1928. The station’s creator and owner, an entrepreneur, inventor, and manufacturer named Powel Crosley Jr. frequently increased the station’s wattage as technology and regulation allowed. In 1934, when WLW increased its power from 50 kW to 500 kW, all other clear-channel stations were operating at 50 kW or less. Now, WLW had the ability to reach most of the country, especially at night, when AM radio waves interact differently with the earth’s ionosphere and become “skywaves.” People living near the transmitter site often got better reception than they wanted; some lights would not turn off until WLW engineers helped rewire houses. Gutters rattled loose from buildings. A neon hotel sign near the transmitter never went dark. Farmers reported hearing WLW through their barbed-wire fences.

Sean’s A15 Season International Broadcasting Statistics

VOA-Greenville-Curtain-Antennas

Many thanks to Sean Gilbert, International Editor at the World Radio TV Handbook, who is kindly sharing some international broadcasting statistics with us again. These statistics were originally posted on the WRTH Facebook group:

Seasonal Language Output Comparison

[F]or the top 19 languages used in international (and Domestic SW) broadcasting. There are 10 seasons worth of data to compare. In those 10 seasons, we have seen an overall drop of 33%, the biggest casualties being Farsi, German, Portuguese, Spanish, Russian, English & Indonesian. Tibetan is usually fairly stable with it’s output being pretty constant over the past 9 seasons – this season, however sees a huge increase in output (+69%), mainly due to the USA hiking output of the language this season. In sheer numbers of data lines (which is how this table has always been generated), English is the biggest casualty, dropping 104 transmission periods per week.

A transmission period is based on the following data structure:
Shown below are 2 “transmission periods” for WWCR and 1 for WWRB. 2 in English and 1 in Spanish. These transmission periods cover a weeks worth of output on that frequency at that time for that broadcaster.

WWCR 1630-2100 English wcr 100 NAm,Eu,NAf daily 15825
WWCR 2100-2200 Spanish wcr 100 NAm,Eu,NAf daily 15825
WWRB 0100-0400 English wrb 100 NAm daily 3195

So a transmission period could, in reality, be from 5 minutes on a single day to 24 hours, daily, depending on the broadcaster. There are nearly 5000 of these entries in our database for this season (When I started at WRTH back in 2000, there were over 10000 entries). Of these 5000 entries, over 3600 are taken up by just 19 languages. The other 1400 entries share somewhere in the region of 200 languages/dialects and combinations! Although this doesn’t show how many hours a particular language has decreased by, it does show the ongoing trend in International broadcasting by radio.

WRTH2015A15 International Broadcasting Season Facts

There are 191 schedules listed in the International Radio and COTB (Clandestine & Other Targeted Broadcasts) section of the WRTH A15 schedules file.

Who uses the most frequencies? CRI, with a whopping 279 frequencies in use. The next largest station, by frequency use is (probably quite surprising to many of you) Voice of the Iranian Republic of Iran (VOIRI) with 140 (that is half the amount of CRI!). Next is VOA with 126; then RFA at 112; BBC at 110 then Sound of Hope Radio International with 84 and All India Radio at 67.

Below is a list of the ‘Top 20’ broadcasters in terms of frequency usage. If you were to do a study of actual transmitted time, the list would look rather different. I will shortly post a table showing the top languages, by use, and what has changed over the past 10 broadcasting seasons.

  • CHINA RADIO INTERNATIONAL (CRI): 279 frequencies
  • VOICE OF THE ISLAMIC REPUBLIC OF IRAN (VOIRI): 140 frequencies
  • BBG – VOICE OF AMERICA (VOA): 126 frequencies
  • BBG – RADIO FREE ASIA (RFA): 112 frequencies
  • BBC WORLD SERVICE: 110 frequencies
  • SOUND OF HOPE RADIO INTERNATIONAL: 84 frequencies
  • ALL INDIA RADIO (AIR): 67 frequencies
  • RADIO ROMANIA INTERNATIONAL (RRI): 56 frequencies
  • AWR ASIA/PACIFIC: 52 frequencies
  • RADIO JAPAN (NHK WORLD): 49 frequencies
  • VOICE OF TURKEY (VOT): 43 frequencies
  • RADIO TAIWAN INTERNATIONAL (RTI): 41 frequencies
  • BBG – RADIO FREE EUROPE/RADIO LIBERTY (RFE/RL): 33 frequencies
  • KBS WORLD RADIO: 32 frequencies
  • SAUDI INTERNATIONAL RADIO: 32 frequencies
  • AWR AFRICA/EUROPE: 30 frequencies
  • VATICAN RADIO: 29 frequencies
  • RADIO CAIRO 29: frequencies
  • VOICE OF KOREA (VOK): 27 frequencies
  • FEBC PHILIPPINES: 26 frequencies

63 broadcasters, or so, use just a single frequency.
