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.

“Anatomy of a Field Radio Kit” series on QRPer.com

If interested, I’ve now published both parts of my Anatomy of a Field Radio Kit series over on QRPer.com. This series was originally featured in the June and July 2021 issues of The Spectrum Monitor magazine. Here are links to both articles:

These articles primarily focuses on portable amateur radio field kits, but many of the concepts are ones I also use for my field portable receiving setups like this one.

I hope you enjoy!

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.

Sailing Vessel with Ham Radio History Marks 100 Years (ARRL News)

The schooner Bowdoin is a century old this year. Now owned by the Maine Maritime Academy (MMA) as a training vessel, the ham radio history of the 88-foot (LOA) Bowdoin is often neglected. Constructed in Maine specifically for Arctic exploration, the vessel relied on amateur radio for communication during explorer Donald B. MacMillan’s Arctic Expedition of 1923 and on the MacMillan-McDonald-Byrd Expedition of 1925 — thanks in part to ARRL co-founder Hiram Percy Maxim, W1AW. The venerable vessel, the official vessel of the State of Maine and the flagship of Maine Maritime Academy’s Vessel Operations and Technology Program, recently underwent a complete hull restoration and refitting and has done a little touring to mark its centenary. Its home port is Castine, Maine.

The longwave transmitters MacMillan used on his earlier missions had proved “unable to penetrate the screen of the aurora borealis,” then-ARRL historian Michael Marinaro, WN1M (SK), explained in his article, “Polar Exploration,” from the June 2014 issue of QST. In 1923, MacMillan turned to ARRL for help in outfitting his next expedition with better wireless gear. Marinaro recounted, “It was enthusiastically provided.” Maxim and the ARRL Board recruited Donald H. Mix, 1TS, of Bristol, Connecticut, to accompany the crew as its radio operator.

M.B. West, an ARRL Board member, designed the gear, which was then built by amateurs at his firm, Zenith Electronics. The transmitter operated on the medium-wave bands of 185, 220, and 300 meters, running 100 W to a pair of Western Electric “G” tubes. Earlier exploratory missions had used gear that operated on longwave frequencies. The shipboard station on board the Bowdoin was given the call sign WNP — Wireless North Pole. [Continue reading…]

The Machines That Built America (History Channel)

In 1893, sending information across America is a time-consuming process. Letters travel slowly by land, and those who can afford it, send telegrams along a limited network of fixed wires. But two rival inventors have the same idea for improving things: wireless communication. Nikola Tesla is one of the most famous and successful thinkers of his day, single-handedly changing the way electricity is supplied and generated. Guglielmo Marconi is a young, uneducated Italian inventor who ignores scientific consensus and goes with his gut. Both want to rid the world of wires and send messages through the air. With millions of dollars on the line, the two men battle to dominate the new market and bring radio to the masses. [Click here to view episode on the History Channel.]

Woman fights to have ham radio operations banned after potential interference with insulin pump (WFTV)

MARION COUNTY, Fla. — A Marion County woman is taking on her neighborhood association, in a matter she said puts her health at risk.

Michelle Smith, a Type 1 Diabetic, and a consultant determined that her neighbor’s ham radio hobby might have interfered with the doses of insulin being pushed out from her pump.

The 55+ community where she lives hired that consultant and told the neighbor to shut down his amateur radio station.

But a copy of the community’s rules shows a change was put in place that could pave the way for other similar antennas to be installed.

9 Investigates learned that Smith’s complaint went all the way to the state level.

She wants the Florida Commission on Human Relations to make a determination whether the community’s board and management is doing enough to protect her and others with medical devices.[]

RTE on long wave 252 kHz back on air (Southgate ARC)

RTE carried out essential maintenance of the Long Wave transmitter in Clarkstown, Co. Meath for two months during which period RTE Radio 1 was not available on 252 kHz.

This essential maintenance of the transmitter was due to be carried out in 2020, but was postponed due to Covid-19 restrictions. For the health and safety of those carrying out the works, the transmitter had to be switched off for the works period. Any overhaul has to be completed during the summer months when there is good light and weather conditions.

Transmissions commenced once again last Monday with an output of 500 kiloWatt during daytime and 100 kiloWatt at nighttime.

During this shutdown, one could receive Radio Algeria transmitting on the same frequency with 1.5 megaWatt during the day and 750 kiloWatt at night, broadcasting a varied program.

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.

Jock discovers the joys of ATS tuning with the C.Crane CC Skywave SSB

Many thanks to SWLing Post contributor, Jock Elliott (KB2GOM), who shares the following guest post:


Really cool trick the CCrane Skywave SSB will do — the “radio butler”?

To paraphrase Ratty from Wind in the Willows: ” “Believe me, my young friend, there is nothing–absolutely nothing–half so much worth doing as simply messing about with radios.”

That is precisely what I was doing . . . messing, simply messing about with the CCrane Skywave SSB.

Then I observed something. Just above the LIGHT button is some lettering: “ATS.” Not having taken notice of it before, I looked it up in the manual. It stands of Automatic Tuning System, and the manual says this about it:

“This feature programs all receivable stations in the AM, FM, Air and Shortwave bands to memory buttons. To use ATS, select your desired band: AM, FM, Air or Shortwave, and press and hold the ATS button for two seconds. The CCrane Skywave SSB will scan the entire band and automatically set all available stations in sequence 1-20. If more than stations are available, then the remaining stations will be preset to the next memory page, and so on.”

So I tried it; I punched in a shortwave frequency — 9250 — and pressed and held the ATS button for two seconds. The Skywave then muted itself and went to the bottom of the shortwave bands — 2300 — and started silently scanning through all of the international shortwave bands, hopping from one shortwave band to the next. Occasionally it would stop and silently store a frequency. After a while it stopped, unmuted, and began playing the very first memory that it stored. I checked the other memories that were stored and — sonofagun! — there were stations stored in each memory. Some of them were really faint, and I had to mess with single sideband and bandwidths to make them fully copyable, but they were there, automatically scanned and stored by the CCrane Skywave SSB. Obviously, you might want to repeat the ATS scan as shortwave propagation changes, say, from day to night.

Well, I thought, would it do it also for Air frequencies? Short answer: it certainly will. And it will do the same for AM, FM, and — get this — if you put the Skywave SSB in single sideband mode, it will scan the ham bands, automatically changing sidebands appropriately as it hops from ham band to ham band. Note: when you check the memories stored during an ATS ham band search, you may not find anything there, simply because ham transmissions come and go much more often than international broadcasters.

There is one downside to the ATS function. When the Skywave scans and stores stations, it does so starting at Page 1, Memory 1 of the memory system . . . always. So, if you scan the Shortwave frequencies and store frequencies they will be stored starting at Page 1, Memory 1, wiping out anything that you have already stored there. If you then use ATS on the Air band, it will then write over whatever you stored from the Shortwave frequencies. I wish there were a way for the user to designate at which page in the memory system ATS will begin storing frequencies so that the information stored starting at Page 1, Memory 1 is not constantly overwritten.

However, there is another trick the Skywave will do: if you have used ATS to scan and store Air frequencies in Page 1 of the memory system (which it does automatically), you can then press and hold the UP and DOWN buttons at the same time, the Skywave will then scan through the Air frequencies that are stored there. Further, there is a squelch function on the Skywave that works only on the Air frequencies. So, with a little persuasion (very little), the CCrane Skywave turns itself into a civilian air scanner.

The ATS function on the CCrane Skywave SSB is a bit like having a radio butler: “I say, Jeeves, find me what’s on the air this evening.” A short while later, Jeeves reports back: “Here you are, sir, I found 10 shortwave stations you might like to listen to.”

Frankly, I don’t know if other modern shortwave portable radios offer a similar function, but if you have a CCrane Skywave SSB, give the ATS function a try; it’s pretty slick.
