Experimental Station will Recreate 1906 Fessenden Transmissions

Experimental station WI2XLQ will be on the air on 486 kHz AM for the Reginald Fessenden commemorative transmission. Brian Justin, WA1ZMS, is the licensee. He will transmit for 24 hours starting at 2000 UTC on December 24, with a repeat transmission starting at 2000 UTC on December 31. Justin will use a homebrew 1921-era MOPA exciter with Heising modulation, followed by a modern 500-W linear. The transmission will be the same as in past years — two violin pieces that Fessenden claims to have played as one of the very first voice transmissions from his Brant Rock, Massachusetts, radio lab site. “While doubt remains that such a transmission ever took place, Fessenden did perform some crude voice transmissions over a few miles distance in early December near Washington, DC, as a demonstration for the US Navy,” Justin said. “So, perhaps some credit is due Fessenden for his efforts to transmit the human voice in an era of spark transmissions.”

If you would like more information about Brian Justin and WI2XLQ, check out our interview with him in 2013. Indeed, I successfully heard the 2013 WG2XFG broadcast and posted this audio clip on the Shortwave Radio Audio Archive.

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!


Significant X-class solar flare (Southgate ARC)

There was a global eruption on the sun today. It started with a powerful X1-class solar flare from sunspot AR2887.

The blast created a massive tsunami of plasma in the sun’s atmosphere, which rippled across the entire solar disk. A CME is probably heading for Earth, raising the possibility of a geomagnetic storm on Halloween. More information and updates @ Spaceweather.com.

History of the Ham Radio Callsign (Southgate ARC)

In this video Mike Ritz W7VO looks at the history of amateur radio call signs in the United States

Every legal amateur radio operator in the world has a unique callsign assigned to them by their government, and many of us are better known by our callsign than our given name. But what world event was it that caused these monikers to be? Why are they constructed the way they are? Continue reading

Sam found where genealogy and radio meet

Many thanks to SWLing Post contributor, Sam Alcom (KB3DFJ), who shares the following guest post:


Genealogy and radio meet

by Sam Alcom (KB3DFJ)

Who knew two of my hobbies – genealogy and radio – would joyfully collide in such an unexpected way?

My grandfather died in the 1950s when I was just a few months old, so I didn’t know him, let alone have some misty recollection of him. Seemingly, our only connection was the DNA bloodline though my father.

But as I dove into my family’s history, one web search led me to William H. Alcorn and 3ADJ. What the heck was 3ADJ? I dug deeper and found Amateur Radio Stations of the United States, U.S. Department of Commerce, Radio Division from June 30, 1924. Both of us were hams!

He was licensed as amateur radio station 3ADJ in Port Norris, N.J. with authorization to operate up to 50 watts.

I found him and his 3ADJ callsign again listed in 1925 in the Department of Commerce, Bureau of Navigation, Radio Service publication. The “3” in his sign threw me for a brief loop, but I learned that in the early days of radio Southern New Jersey was part of the third call district along with Delaware, Maryland, Virginia, certain counties of Pennsylvania and the District of Columbia.

The worldradiohistory.com website, a goldmine for anyone delving into all aspects of broadcasting’s past, led me to more publications where I spied my grandfather in the late fall 1925 edition of Radio Listeners’ Guide and Call Book and the 1926 edition of Citizens’ Radio Call Book and Complete Radio Cyclopedia.

The last radio trace I find was in the June 30, 1927, edition of the Amateur Callbook.

It was around this time that the U.S.  began using “W” to start callsigns and I wondered if my grandfather continued with his radio hobby under the new designation. I looked up W2ADJ and found William Czak of West Brighton, N.Y., owning that sign. Likewise, W3ADJ belonged to the University of Maryland in College Park, Md. Both were from 1929.

I dug a little deeper to learn if he possibly had been an amateur prior to 1924, but I saw 3ADJ licensed to Horace Derby of Norfolk, VA., 1920 through 1923.

His amateur radio interest appears to have started sometime after 1921 and a stint in U.S. Navy as a Seaman Second Class and then seems to have waned – at least license-wise – as marriage and the first of my aunts, uncles and my dad were being born.  I wonder if my dad had known about his dad’s radio hobby. In all the years I’ve been a licensed ham and bono fide radio nerd, he never mentioned it.

Of course, learning on this radio connection to my grandfather raised a host of other questions. Did he enjoy CW as much as I do? What kind of contacts was he making with 50 watts? Would he have admired the WAS and DXCC award certificates hanging on my wall? Would my hefty binder of shortwave QSL cards impressed him?

So, I’ll keep poking, looking for more radio connections. Who knows, maybe, somewhere, there’s a 3ADJ QSL signed by my grandfather.

1951 US Army Film: Independent Radio Station WMCA

Many thanks to SWLing Post contributor, Kris Partridge, who shares the following:

I belong to a FaceBook group “The Broadcasting Club” and [recently] there was posted a link to a YouTube video of a 70 year old 1951 US Army film called “The Independent Radio Station WMCA”. It’s worth a view to show what the thinking was 70 years ago:

From YouTube:

In 1951 the US Army made this film showing how an independent radio station operates. There was certainly a cold war propaganda motive for the US Army to produce this film, but today, when independent stations are a rarity, this film gives a detailed view of how a large market, independent radio station, WMCA New York, went about producing its programming and paying the bills in post war America.
