Sam found where genealogy and radio meet

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.

Shortwave Radios Keep Up With Tech (Radio World)

There’s still lots to listen to, and new ways to do it

Surprise! Shortwave radio as a broadcast medium is holding its own, despite the intrusion of the internet, transmission cutbacks by major broadcasters such as the BBC World Service and Voice of America and abandonment of the SW bands by other state-owned broadcasters.

Meanwhile, the ways in which people listen to SW radio transmissions are evolving, because SW receiver manufacturers are keeping up with the technological times.

Stayin’ alive

There is no doubt that the variety of stations on the SW bands has declined, due to the end of the Cold War — the propaganda war of which drove the medium in the 1950s and 1960s — and the emergence of the internet.

Special operators are already dealing with a shady piece of Chinese technology the US has been warning about. (Business Insider via MSN)

  • The spread of 5G mobile communications technology is creating new problems for the US military.
  • Compromised networks could give adversaries an opportunity to monitor and attack US personnel.
  • See more stories on Insider’s business page.

In an increasingly interconnected world, the US military is facing new challenges in old stomping grounds.

Even though the US isn’t at war with China, competition with Beijing is already raging, and conventional and special-operations troops deployed around the world are exposed, either directly or through proxies, to Chinese technology that could hinder them in a conflict.

The worst offender is 5G, the same mobile communications technology ordinary people use or will be using in the future.

[…]However, Chinese firm Huawei – which is suspected of stealing its 5G technology from a Canadian firm through cyberattacks – has been deploying its 5G technology worldwide.

Given China’s peculiar national security laws, which require individuals and companies to cooperate with the Chinese security services, any Huawei technology around the world is a potential threat to privacy and national security. Through Huawei, Beijing could spy on or disrupt infrastructure and operations during peace or war.

Governments have realized the danger and have been banning Huawei from their networks. The British government did so in 2020, and the US Federal Communications Commission designated Huawei a national security threat in 2021, following several Chinese cyberattacks.[]

Chip Shortage Hits Radio Technology Marketplace (Radio World)

The severity of the global computer chip shortage has broadcast equipment manufacturers finding creative ways to manage supply channels while trying to meet product demand.

Despite the semiconductor shortages, people in the radio technology marketplace who spoke with Radio World say products are still being shipped, with mostly minor delays, thanks to prior planning. Equipment suppliers said they hope the semiconductor shortage will ease soon, perhaps by early 2022.

The story of the Radio Hat, 1949 (Rare Historical Photos)

In 1949, Victor Hoeflich held a press conference to introduce the “Man from Mars, Radio Hat”. Hoeflich knew a picture would tell the story so he had several teenagers modeling the radio hats for the reporters and photographers. Soon pictures and news stories appeared in newspapers coast to coast. The articles typically included a photo of a young lady wearing the hat and a six-paragraph story.

Although the radio hat had a futuristic appearance at the time, this was in fact due to technical limitations. While the transistor had been invented in 1947, it was still experimental and not widely available. The hat’s radio relied on vacuum tube technology, and Hoeflich made the tubes a prominent feature, as well as the loop aerial. The tuning knob sat between the two valves. The battery was carried in the user’s pocket.
