Polar Bear Mushing: 1923

Screenshot 2023-01-11 1.18.43 PMA hundred years ago this month, the cover of Popular Mechanics for January 1923 showed a self-explanatory transportation idea that, for some reason, never caught on. For the really big loads that sled dogs couldn’t handle, simply replace the dogs with polar bears! They’re fast and they’re strong, and they could haul sleds of unimaginable size.

“While the Eskimo is, by necessity, too busy with hunting and fishing to attempt training the bear in a serious way,” the manager of a fur company saw real potential in the idea. Of course, “in selecting the team, care would have to be exercised in eliminating animals showing  predisposition to temper.”

So even though the Inuit who had lived there since time immemorial didn’t seize the idea–simply because they were too busy–the fur company can send a man in to tackle the job.

The idea never caught on, and we’re guessing because the man sent in to tackle the job wound up as a tasty snack for one of the bears.



Kerchunk: The Sound of Safety

Book Review: War Diaries by Volodymyr Gurtovy

My friend Volodymyr “Wlad” Gurtovy, US7IGN, has published a book about his experiences living in Kyiv, Ukraine, in the middle of a war. Wlad, like me, is an attorney, and lived a middle-class existence similar to mine, until Russia invaded eastern Ukraine in 2014. He and his family then relocated to Kyiv, but with Russia’s 2022 invasion, he was once again in the middle of the war. His wife and teen son and daughter evacuated to Poland, where they were able to find an apartment, thanks in part to the generosity of friends in America and elsewhere.

He remained behind, partly because he was prohibited by law from leaving, but mostly because he felt the need to stay behind and defend his native land.

The most compelling part of his book is his account of the mundane details of life in the middle of a war. Wlad lives in a fifth-floor apartment building in the middle of a city of 2.8 million (prewar population). Some days, the supermarkets are open, and some days they are not. The mail continues to go through, but some days, it’s too dangerous to go to the post office to pick it up.  Power, water, and heat are sometimes turned on, but they’re often unavailable. When he needed dental work, he was surprised to find the dental office near his home open, staffed by dental students.  There are even a few accounts of his visits to court on behalf of some pro bono client.  To me, the descriptions of how he navigates this dystopia are fascinating, especially since his life prior to the war wasn’t too different from mine.  Many who follow this blog have an interest in emergency preparedness, and I’m sure they will also find this book compelling.

Of course, since Wlad is a ham, radio is a main character in the story. He gets much of his information from the broadcast radio, and one of his main roles has become that of radio repairman so that others can remain in touch when their radio has problems. He also recounts listening in directly to Russian pilots and both Russian and Ukrainian troops.

As the title suggests, it’s written in chronological format, and you’ll have a hard time putting it down, wondering what’s going to happen the next day.

The book is available at Amazon, as a paperback, hard cover, or Kindle.

If you feel moved to provide additional assistance to Wlad’s family, please see our crowdfunding campaign to help with their needs at GoFundMe or GiveSendGo.

Hitler’s First Mention in the New York Times: Nov. 21, 1922

1922Nov21NYTA hundred years ago today, November 21, 1922, Hitler first made the pages of the New York Times,  page 18 to be specific. The newspaper’s Munich correspondent concluded that the “Nationalistic anit-Semitic movement (the word “Nazi” didn’t appear in the article) has now reached a point where it is consiered potentially dangerous, though not for the immediate future.”

The paper noted that the anti-Semitic propaganda had reached a point where “a number of prominent Jewish citizens have sought asylums in the Bavarian highlands, easily reached by fast motor cars, whence they could hurry their women and children when forewarned for an anti-Semitic St. Bartholomew’s night,” (which happened eleven years later).

But the paper reassured readers that this couldn’t happen: “Several reliable, well-informed sources confirmed the idea that Hitler’s anti-Semitism was not so genuine or violent as it sounded, and that he was merely using anti-Semitic propaganda as a bait to catch masses of followers and keep them aroused.”

Interestingly, the article presupposes that reader’s have some knowledge of Hitler, as the article doesn’t bother to use his full name.

Hunt the Bleeper Game: 1972

1972NovPracWirIf you need to liven up Junior’s next party, you can put together this circuit for a fun game of “hunt the bleeper,” as described in the November 1972 issue of Practical Wireless.

The magazine noted that British children love noise, and this is equally true on this side of the Atlantic. The beeper, which draws only 600 microamps, puts out a high pitched tone at a low level. The device was to be hidden, and the children would be split into two teams to find it. There were two strategies available: They could concentrate on finding the device, or they could make so much noise to keep the other side from hearing it.

The cost was said to be 50 pence, which didn’t include the case, which was one of the then-ubiquitous 35mm film can, which was deemed to be free. Even though they’re no longer free, like everything else, you can find them on Amazon.

1947 TV Microwave Relay

1947NovRadioNewsSeventy-five years ago, this microwave relay station was under construction atop Jackie Jones Mountain near Haverstraw, NY. It was one of seven microwave relay stations linking Boston and New York, delivering television programs with a 1 watt signal on 4000 MHz.

It is pictured here on the cover of the November 1947 issue or Radio News.



Almo Radio Company, Camden, NJ, 1952

1952MayRadioNewsShown here is the Camden, NJ, location of Almo Radio Company. The company, founded by Morris Green and Al Margolis, was based in Philadelphia, and had expanded to a chain of six stores, plus warehouse. It served as a parts jobber for radio dealers on the East Coast. To make sure dealers could be quickly served with their needed parts, each branch store had an inventory of $75,000 at all times, with the warehouse stock valued at $600,000. It employed 12 salesman, each covering an average of 200 accounts.

The photo appeared 70 years ago on the cover of the May 1952 issue of Radio News. According to the magazine, the company was one of 1500 parts distributors nationwide. According to this 1956 ad, the company was located at 1133 Haddon Ave.



1962 License-Free Projects

1962MayEISixty years ago, the May 1962 issue of Electronics Illustrated featured these two projects to build unlicensed devices for use on 11 meters. The first is the walkie-talkie shown at the top. The three-transistor transceiver was powered by two mercury batteries. It’s 100 milliwatts were said to have a range of about 1000 feet.

The other project is a transmitter to be installed in a model rocket, weighing in at only 1-1/8 ounces, including battery. It had a range of about 1500 feet. The circuit was shown for 11 meters, where it could operate license fee, but the magazine also pointed out that good results were had on 10 or 40 meters for licensed hams.

Various types of telemetry could be used, but to start, the magazine recommended a photocell, mounted near a small hole in the side of the rocket. This would allow a measurement of the rocket’s spin, since it would oscillate in time with the photocell pointing at the sun.

1947 Tom Thumb Portable

1947MayRadioRetailingIf you were wondering what the most wished-for radio of 1947 was, this was it, at least according to the manufacturer, the Automatic Radio Manufacturing Co., 122 Brookline Avenue, Boston.

The radio in question was the Tom Thumb portable, a four-tube (plus selenium rectifier) portable that came with its own rechargeable battery, undoubtedly a two-volt lead-acid cell. It could operate off battery, AC, or DC, and the battery could be charged internally (but now with the radio playing).

It was rather pricey, at $47, the equivalent of over $600 in 2022 dollars.

The ad appeared in the May 1947 issue of Radio Retailing.
