How to Fight Fire Bombs: 1942

1942Jan24RadioGuideEighty years ago today, according to the January 24, 1942, issue of Radio Guide, fire bombs were “ugly, dangerous weapons the enemy will eventually try to use right here in the U.S.A.” According to the magazine, hundreds of such bombs, each weighing only a couple of pounds, could carpet an area, causing particular damage if they hit the roof or attic of a building. Bing Crosby, therefore, took a few minutes out of the Kraft Music Hall program to allow Maj. John S. Winch to discuss how to deal with the threat.

The wrong thing to do was to hit them with water as soon as they landed, since the water would ignite the magnesium. It was necessary to wait about sixty seconds, and then if attacking it with a hose, to use a mist of water. The idea was to let the bomb burn out, and keep nearby material from catching fire. Buckets of sand stored at strategic locations were also indicated, according to the magazine.

This threat, of course, never materialized in the continental U.S.  For the closest thing to happen, be sure to read our four-part series on the Fu Go Fire Balloons.

Bomb Shelter Radio, 1942

1942JanRadioRetailerThe January 1942 issue of Radio Retailing stressed to its readers that their trade was an essential one. Radio was a necessity in every home, factory, office, and car. The radio dealer’s patriotic duty was to keep ’em working.

Here, the magazine notes that Americans might have need for bomb shelters, and a working radio would be an essential part of that shelter.



1942 Radio Repairman Short Story

1942JanRadioServiceDealer1This interesting short story appeared 80 years ago in the January 1942 issue of Radio Service Dealer. The story appeared in the magazine’s “Serviceman’s Diary” feature written by contributing editor John H. Potts.

The story must have been written days after Pearl Harbor, and the author is fantasizing about an air raid warning. Ordered to shelter by a police officer, a radio repairman found himself in front of a big apartment building. Somewhat counter-intuitively, he remembered that the safest place would be on the third or fourth floor, so he went to the third floor and rang the bell of the first apartment he saw. An attractive woman answered the door, and the story has its happy ending when she falls for him after he is able to fix the radio.

It’s an interesting prediction of home front life early in the war, and makes an interesting read:



1942 Code Practice Oscillator

1942JanPMCPOEighty years ago, these gentlemen probably realized that they would soon be serving in the armed forces, and their stint would probably be more comfortable if they came to their induction in possession of a skill useful to Uncle Sam. Therefore, they have undertaken to learn Morse Code, thanks to this one-tube oscillator described in the January 1942 issue of Popular Mechanics.

The set used a single 117L7-GT tube, whose 117 volt filament meant that it could run straight off the AC power lines, without worrying about dropping resistors or transformers. It had plenty of volume, which could be controlled with a volume control, to drive a speaker or up to 20 pairs of headphones for group practice.

Happy New Year!

Happy New Year from OneTubeRadio.com!

We’ve had a tough couple of years, but it wasn’t “Siege of Leningrad” tough. The picture shown above was taken 80 years ago today at the Leningrad Children’s Hospital, where the children were celebrating the new year 1942.  Despite their predicament of being surrounded by the German army, these young comrades seem stoic and determined to endure.

While these children were all born before the start of the siege, the fierce battle surprisingly marked the beginning of a baby boom within the city. In 1943, the number of marriages in the city were up 13%, leading to a 1944 birth rate that was 23.6% higher than the pre-war level. From the start of the siege, special efforts were made to ensure nutrition for infants, and surprisingly, infant mortality actually declined in 1942.

You can read more about this aspect of the siege of Leningrad at the Russian Wikipedia.  Google should provide a good translation of the fascinating article.



KIRO Seattle; Milton Shaw, 1917-1944

1941Dec29BCEighty years ago today, the December 29, 1941, issue of Broadcasting showed Private Milton Shaw of Cleveland, Georgia, standing guard over the 50,000 watt transmitter of KIRO, Seattle, sited on Vashon Island. The soldier was one from the 41st Division. The magazine claimed that the station was “located in the center of a large colony of Japanese nationalists.” The magazine noted that the station was the only 50,000 watt station north of San Francisco and Salt Lake City.

free-vector-poppy-remembrance-day-clip-art_106032_Poppy_Remembrance_Day_clip_art_smallAccording to this source, Shaw was killed in Action in New Guinea on June 17, 1944, and his remains are buried at Oakwood Cemetery, Oakwood, Georgia.



1941 Five Tube Portable

1941DecPSEighty years ago, this young woman is pulling in a favorite program with this camera-style portable radio. The brand is not stated, but it has five tubes, including the rectifier, and can operate either from battery or, as she is using it here, standard household current. It had the option of use with a separate window antenna to increase the sensitivity. It was finished with gray plastic, with a dark blue covering of simulated leather.

A few days after this picture appeared in the December 1941 issue of Popular Science, she was probably using the same set in a more somber mood to pull in the latest bulletins from Pearl Harbor.



WW2 “Ivan The Terrible” Broadcasts

1971NovEIFifty years ago this month, the November 1971 issue of Electronics Illustrated carried the story of Ivan The Terrible, the Soviet interloper who interfered with Nazi broadcasts during the war.

Deutschlandsender broadcast its German home service on 191 kHz, with broadcasts including the news. One day in 1941, listeners were able to hear additions to the news broadcast. For example, if the announcer said, “new victories have been won by the Wehrmacht,” another voice completed the sentence with “in the grave.”

The voices were coming from Soviet Station RW-1 at Noginsk, near Moscow. The engineers at that station were able to tune the 500 kW transmitter from its original frequency of 172 kHz and synchronize it with the German station to avoid any heterodyne. Eventually, the Germans were forced to put their news broadcasts on mediumwave, and use their powerful longwave transmitter for entertainment programs.

When the Russian source of the broadcasts was known, it was dubbed Ivan The Terrible, and that name is used in this 1941 Time magazine article from September 15, 1941.

According to the 1971 Electronics Illustrated article, British and American intelligence issued a report disclosing the identity of Ivan the Terrible. Unfortunately, however, the American copy of the report was misfiled and was lost somewhere in the Washington catacombs. The British copy was still covered by the Official Secrets Act and couldn’t be made public until 1991.

But the author of the article did enough digging to give “a pretty good idea” as to the identity. According to the 1971 article, the instigator was Sololmon Abraham Lozovsy.
Despite his service to the Soviet Union, Lozovsky became the victim of one of Stalin’s purges. Even though Krushchev later issued a pardon, it came a bit too late, since Lozovsky was shot in 1952.

The actual voice of Ivan The Terrible was that of Bohemian Ernst Fischer.  After winding up on the wrong side of the Austrian civil war, he found his way to Moscow where his fluency in German was put to good use. After the war, Fischer brought his communism back to Austria, where he remained a figure in the Austrian Communist Party until 1969, serving as the Communist Minister of Information immediately after the war.

1941 ARRL Battery-Powered Equipment Test

1941SeptQSTToday marks the 80th anniversary of an ARRL contest that, as far as I can tell, happened only one time, the 1941 ARRL Battery-Powered Equipment Test. The announcement shown here appeared in the September 1941 issue of QST, and the full rules appeared in the October issue.

While June Field Day was, and is, dominated by gasoline powered generators, this event was “aimed at individual-class lighter weight equipment.” To stress this, the official contest exchange included the transmitter weight. Participants could work non-contest stations for one point, with an extra point for sending and getting acknowledgment of the transmitter weight. If the other station was battery powered, there was an additional point for copying their transmitter weight.

WFD1In my opinion, the small advantage gained by an electric generator is more than offset by the convenience of operating with batteries.  For example, as I previously reported, I worked the 2021 Winter Field Day contest with my trusty fish finder battery.  Especially if you’re thinking in terms of emergency preparedness, it’s an easy matter to keep fully charged batteries on hand, whereas a generator usually requires a certain amount of maintenance, as well as keeping fuel on hand.

The maximum power level for the 1941 contest was set at 30 watts, although it would have been a stretch to get more from battery-powered equipment. Operation from the field was encouraged, with a multiplier of of 2 for all contacts. However, stations could also be operated from home, as long as batteries provided all power for transmitter and receiver. The contest rules reminded hams that portable operation required 48 hours advance notice to the FCC.

There were categories for both HF and VHF (called in those days “low frequency” and UHF). Interestingly, HF operation was confined to the daylight hours, but UHF could continue all night. The UHF category allowed 5 meters and up, but all of the entries in that category used exclusively the 2-1/2 meter band.

The results weren’t published until after Pearl Harbor, in the March 1942 issue of QST.  They are shown below, with W8RMH, Edgar Cantelon of Detroit, later W8CV, taking the honors for high score with 82 contacts from a portable location. Among the calls is one familiar one, that of Don Wallace, W6AM, whom we have previously profiled.

In the “UHF” category, W2NPN took top honors, with an impressive 72 contacts from a portable location, all on 112 MHz.

The “transmitter weight” is an interesting piece of data to exchange. Even though this contest is no more, transmitter weight is still a factor in at least one contest. While it’s not sent on the air, transmitter weight is an important factor in scoring for the Adventure Radio Society Spartan Sprint contest.  In the most recent runningK4PQC managed 11 contacts with a station (transmitter, receiver, headphones, and battery) weighing in at 0.1268 pounds (2 ounces). He reported that his station consisted of a 40 meter ATS-3b.  The rig is designed to fit inside an Altoid’s tin, but he ran it without the case to shave a whopping 1.2 ounces off the station weight.

I suspect W8RMH’s rig weighed a bit more in 1941, but he probably used a lot of other gear, both larger and smaller, over the years. According to his 2016 obituary, he had just started working at WJBK radio (now WLQV) shortly after this contest, and he was in the transmitter room when the station reported that Pearl Harbor had been attacked. He then secured a new job in a defense plant, later becoming a radio operator for bomber test flights. He later served in the Merchant Marine as a radio operator, and then the army. He later went back to WJBK and served as an engineer for their TV station.

CBS Berlin Correspondent William Shirer

1941Oct11RadioGuideShown here, in the October 11, 1941, issue of Radio Guide is a photo of CBS correspondent William Shirer, conferring with a German naval officer acting as his censor. Shirer had recently returned to America after being posted in Berlin, and the magazine offers some of his recollections.

For most of his term in Berlin, Shirer had lived in an apartment, but for the last year of his assignment, he had lived at the Adlon Hotel.  Since the hotel catered to foreigners, it was one of the last places in Berlin to have hot water constantly available. In fact, Shirer often met with officials in his room, and was able to provide those officials with a hot bath.

The article served partially as a tease for Shirer’s forthcoming book, Berlin Diary,  which is still available. The book recounted his years in Berlin. Shirer is best known as the author of The Rise and Fall of the Third Reich.
