Wartime 3-Tube Regenerative Receiver

Jan45PMrcvrWartime parts shortages were a major inspiration for the design of this short wave receiver from the January 1945 issue of Popular Mechanics. The lamp isn’t there for decoration; it’s one of the parts.

The receiver used three identical tubes, the 6C5. It ran directly off house current. The three 6-volt filaments are run in series, and to avoid the need for a filament transformer, a 40-watt light bulb in series is used to drop the 110 volt house current to the 18 volts necessary to light the tubes. A standard household receptacle is mounted directly on the chasis, into which a desk lamp can be plugged. Another alternative was to mount the bulb directly on the chasis, using a lamp adapter plug.

Speaking of the chasis, the set is constructed on a literal breadboard, sourced from the nearby dime store. The coil form was also obtained at the dime store, in the form of a plastic drinking cup. The coil is wound with cotton-covered wire, held in place with fingernail polish.

Jan45PMrcvr2The two variable condensers, one for tuning and the other for regeneration, were scavenged from old broadcast receivers. For regeneration, only half of the 350 mF condenser is used. For tuning, the two sections of the 350 mF condenser are wired in series, rather than parallel, resulting in 88 mF, which is better suited to the 25 and 31 meter bands the set tunes. An additional five resistors and five capacitors round out the parts list.

One of the 6C5 tubes is used as a rectifier, one serves as the regenerative detector, and the final one serves as an audio amplifier. In the 1943 Allied Radio catalog, the tubes are available for 56 cents each. The catalog notes that most glass tubes were available in limited quantities. However, it noted that the metal tubes were generally available only to high priority customers.

Canadian Wartime Nickel Contains Morse Code

The 1943-45 Canadian five cent coin, known as the “Victory Nickel,” is unusual in that it contains Morse Code.  Most Canadians were unaware that they were carrying a Morse message in their pocket, since the code is discernible only upon close examination with a magnifying glass.  It is partially visible on the image shown here.  It’s on the reverse of the coin, and runs clockwise along the edge.  It begins just to the left of the letter “N” in the word “CENTS”.

The beaver design currently appearing on the coin first appeared in 1937, but the coin was redesigned during the war.  The reverse featured the letter V, with a dual significance.  In addition to being the Roman Numeral for five (which was used on the U.S. Liberty nickel from 1883-1912), it was also the symbol of victory.

And with little fanfare, it also included the message, in Morse Code, “WE WIN WHEN WE WORK WILLINGLY.”

The Canadian Mint re-issued the design in 2005, dated 1945-2005, to commemorate the 60th anniversary of the end of the war.  However, the 2005 design did not include the Morse Code inscription.

Specimens of the coin in which the full message is legible are fairly uncommon.  Most were made of steel, plated with nickel.  The sheets were plated before the blanks were cut out, resulting in the edges being unplated.  This has caused most of them to rust around the edges, making the Morse Code illegible.  In the example shown above, the words “WE WHEN WHEN WE” are very legible, but most of the rest of the message is impossible to make out.

The 1943 coin was made of tombac (a brass alloy), and the message is more likely to be legible on specimens from that year.

AS-19/TRC-1 Antenna System at the Siege of Bastogne

US Army Signal Corps photo, Wikipedia.

This photo was taken 70 years ago today, 26 December 1944, during the siege of Bastogne, part of the Battle of the Bulge.  It was taken by a U.S. Army Signal Corps photographer, and shows troops of the 101st Airborne Division as they watch C-47s drop supplies to them. Of course, if you’re a ham, your eyes zero in on the antenna, shown below, and you see what appears to be a horizontally polarized VHF Yagi antenna on top of a tall mast. If you’re like me, you wonder what it is and what it’s doing there.

BastogneAntenna

I apparently wasn’t the first to ask the question, since it had already been asked and answered on K4CHE’s site.  The antenna in question is, indeed, a VHF Yagi, and it was part of a telephone relay system operating with 50 watts between 70-100 MHz. This was an FM full-duplex relay that could handle one voice conversation or four teletype channels.  It was linked to telephone circuits and represented a low-cost alternative to stringing phone lines.  A diagram of the antenna system, known as the AS-19/TRC-1, is shown below.

AS19TRC1

AS-19/TRC-1, Radio News, Jan. 1946.

Later models had greater capacity, such as the one whose operating manual is available at this link.  The range obviously depended on the terrain, but was normally used for links of 25-100 miles.  The technical details are discussed in detail in the Radio News link below.  Not surprisingly, the Yagi antenna was not referred to by that Japanese name at the time.  It’s referred to as a “double H” type antenna.

I haven’t been able to find it, but one of the sources above indicated that a ham magazine published an article for converting this antenna to 6 meter use.

1944 Teen Girls: Homework With the Radio Full Blast

1944TeenSeventy years ago, Life Magazine, December 11, 1944, featured the life of teen-age girls, and noted that all six million of them “live in a world all their own–a lovely, gay, enthusiastic, funny and blissful society almost untouched by the war.” Music stores bulged with girls listening to the singers and bandleaders they have made famous, and “half a dozen radio programs are aimed at homes where a daughter will cut off her father’s news to follow the fictional adventures of a contemporary.”

1944FullBlastShown here and above is Miss Pat Woodruff, a high school student from Webster Groves, Missouri, a suburb of St. Louis. She’s wearing her “after-school costume of blue jeans and a checked shirt,” undoubtedly getting ready to tune in one of those programs on the console radio in the parlor. She quickly gets to work tackling her homework, but with the radio playing full blast.

1944PhonographWhen the girls featured in the story were not listening to the radio or talking endlessly on the telephone, the phonograph occupied them. Here, a group of girls spends 2-1/2 hours listening to two dozen records at a record store, buying only one or two. Here, a group is completely engrossed listening to Dick Haymes‘ Together.

Dates were usually double, the article noted. Teen-age girls were primarily interested in themselves, with high-school boys running a poor second. Servicemen stationed near town rated last. An old high-school boy home on leave in uniform, however, was in a class by himself and rated tops.

The First Shot of WW2 in US Territory, 1939: The Arauca

The Arauca (left). The Orion is barely visible, circled, at the right side of the photo. Big Spring (Texas) Daily Herald, December 21, 1939.

The first shot of World War Two to be fired in the United States was 75 years ago today, on December 19, 1939. On that day, the merchant ship Arauca sailed into Port Everglades, Florida, flying the Nazi flag. Just off the Hillsboro Lighthouse, the British cruiser HMS Orion was pursuing the Auraca and signaled for the Arauca to proceed into international waters. Not surprisingly, the Arauca’s captain did not heed the message. The British ship then fired a shot across her bow from not more than 12 miles away from the U.S. coast. This was a violation of U.S. neutrality, but there’s no record of any protest having been filed. The captain of the Arauca sailed the ship into the U.S. port. The Orion remained in the area for a few days, but when it disappeared, the Auraca‘s crew was seen painting the ship grey, preparing to make a run for it in the next fog.

But the Auraca never left port under its own steam. What the Royal Navy attempted to do was instead accomplished by American lawyers.

The Auraca had been sailing from Veracruz to New Orleans. She was on her maiden voyage, having sailed to Havana prior to the outbreak of hostilities. After the war started, despite the captain’s request to return to Germany, she was sent to Veracruz.

The Auraca was carrying a cargo of sugar, and about a dozen German passengers returning to Germany from Mexico. She was also carrying fuel that was thought to be in excess of her own needs, leading to speculation that she was an auxiliary military vessel tasked with refueling German warships. This was a critical distinction, because if she were deemed to be an auxiliary, she would be allowed in port for only 24 hours. It turned out, however, that this determination was never made, because the U.S. civil courts saw to it that the vessel would never again see service to Germany.

The ship’s presence in Ft. Lauderdale was quite a tourist attraction. In addition to those along the Florida coast who witnessed the shot across the bow, thousands flocked to Ft. Lauderdale to see the Nazi ship sitting at the dock.

The morning after the Auraca‘s arrival, a libel action was brought in the U.S. District Court in Florida. The Imperial Sugar Company of Galveston, Texas, filed the suit against the ship’s owner, the Hamburg-American Line, for damages for breach of contract for an earlier transaction predating the war. Other claimants followed suit, and eventually claims of over $138,000 had been filed, in addition to the Port’s claim for docking fees. To release the ship, the owners would have to post bond of more than $277,000, which never happened. The ship became a permanent fixture in Ft. Lauderdale.

Most of the passengers and crew were forced to remain aboard the ship. The captain and officers were initially allowed into the town of Ft. Lauderdale, and the captain was quite willing to give interviews to the many U.S. reporters who pursued him.

The ship and crew, basically imprisoned aboard the ship, remained until March 20, 1941, when President Roosevelt arrived at Port Everglades for a fishing trip. From aboard his presidential yacht, anchored just yards from the German ship, he was upset when he “caught sight of a Nazi flag fluttering over American soil.” Before the end of the month, 60 ship seizures, including the Arauca, took place under the Espionage Act, on the grounds that the vessels posed a threat to American harbors.

The Justice Department then obtained arrest warrants against the entire crew on the grounds that the crewmen, imprisoned in the ship, had actually overstayed their visas. The Coast Guard arrested the crew and replaced the Swastika with Old Glory. The crew was later transported to the Broward County Jail, then to the Dade County Jail, and finally to Ellis Island. They were still at Ellis Island when the U.S. joined the war, and the men were interned at the Fort Lincoln Internment Camp in North Dakota.

The litigation surrounding the ship dragged on until well after the war was over. The ship was eventually sold, and the proceeds held in trust for the various claimants. A 1949 decision, Suns Insurance Office v. Arauca Fund, 84 F. Supp. 516 (D.C. Fla. 1949), involved the computation of damages for contracts payable in reichsmarks. Since the reichsmarks were “worthless in terms of dollars” at the time of the deicision, that claimant got nothing. The attorneys didn’t fare much better, in what appears to be the final reported decision of the case, United States v. Knauth, 183 F.2d 874 (C.A. 5 1950). In that decision, the Fifth Circuit held that the prevailing attorneys did not have a lien against the vessel, since their cause of action actually arose out of a claim involving a different vessel.

The ship itself was purchased in 1941 from the U.S. Maritime Commission by the South Atlantic Steamship Company of Savannah, Georgia, which towed the ship to Mobile and renamed her the Sting. After such a long period of disuse, the ship was in need of extensive repairs and was eventually handed back to the U.S. Government. In April 1942 the ship, now named the USS Saturn, was in the hands of the U.S. Navy. She suffered numerous mechanical problems, but operated along the East Coast and to Carribean bases such as Trinidad and Guantanamo. She made one transatlantic crossing to England in 1943, and trips later in the war to the Mediterranean, Iceland, and the Carribean. She was decommissioned in 1946, but held in reserve until 1972 when she was sold to a Spanish firm for scrap.

Note:  In many sources, the name of the ship is incorrectly reported as the Aranca.  This appears to have originated in typographical errors in many newspaper accounts in 1939.  The ship was intended for trade with South America, and was given the name of the Arauca River of Colombia and Venezuela.

Merry Christmas Hans: 1939

Dec1939BL

The December 1939 issue of Boys’ Life magazine carries an interesting short story, “Merry Christmas Hans” by Philip Lightfoot Scruggs. It’s full of technical inaccuracies, the author’s unfamiliarity with Amateur Radio, and even countless FCC rule violations. But it’s an interesting look at how Amateur Radio was viewed 75 years ago, and it pretty conclusively puts to rest the assertion that the Boy Scouts are somehow designed to militarize boys.

The hero of the story is Dave Smith, W2KSM. (It looks like the call was really in use, as shown by what looks like a Sweepstakes entry in this 1938 QST. And it was held in 1954 by one Howard M. Ames Jr.)

Young W2KSM, a 17-year-old Eagle Scout, decided to get on the air on Christmas Eve to wish a Merry Christmas to his DX friends in France, England, Belgium, or Holland. Much to his surprise, he heard the voice of Hans Schuler in Germany, where Amateur Radio was not allowed. (Amateur Radio actually did exist in Germany, and even continued somewhat during the war. Germany was one of the few belligerent countries where there were still a few hams on the air, even during the war. For more information, see my earlier post.) The story contains an editor’s note pointing out that the story was written before war was declared. Dave asked Hans what would happen if he was caught, and Hans replied, “the concentration camp at least.”

Still, the two continue their conversation, as Dave tells of freedom, and Hans tells of the repression in Germany, and even explains how he can quickly dismantle the station and antenna if the Gestapo got too close. Another Scout in New York City just happens to be listening to the contact, and alerts his father, a network executive, who spontaneously decides to broadcast the contact nationwide where millions, including Dave’s parents, listen to the boys talk.

Dave tells about Boy Scouts, and Hans tells of his experience preparing for war in the Hitler Youth. Dave concludes the contact by reciting the Scout Oath and Law, “that is our Scout Oath and Law, Hans–what we try to live by,” as Hans prepares to hastily disassemble his clandestine set.

Dave walks downstairs wondering whether his family will believe it, only to hear the end of the broadcast in which he and Hans had a starring role.

Scuttling of the Graf Spree, 1939

Montevideo1939

75 years ago today, December 17, 1939,thousands of curious residents of Montevideo, Uruguay, gathered at the docks overlooking the estuary of the Rio de la Plata. They can be seen in this wire service photo which appeared in the Milwaukee Journal the next day.

The ship visible three miles from shore is the German warship the Admiral Graf Spree.  Two years earlier, the ship had participated in the Coronation Review for King George VI. In 1939, Germany was at war with Britain, and in the first months of the war, it had sunk nine British ships in the South Atlantic. It was confronted by British ships on December 13 and suffered considerable damage. It sailed into neutral port in Uruguay to effect repairs. Uruguay, however, allowed it only 72 hours in port, an insufficient amount of time.

The British began transmitting on frequencies known to be monitored by the Germans, and gave the immpression that a much larger force was en route to Uruguay than was truly the case. The Germans believed the misinformation, leading the Graf Spree’s captain to believe that a return to Germany would be impossible. He sailed the vessel into the Rio de la Plata, and 20,000 gathered on the docks to witness what they believed would be a battle between the German ship and British vessels. Instead, the Graf Spree prepared to scuttle the ship. At 8:55 PM, after an Argentine tug evacuated the crew, the charges were detonated, treating the spectators on shore to an explosion visible for miles.

While much of the ship was salvaged, parts are still visible in the Rio de la Plata. The ship’s captain committed suicide in his Argentine hotel room three days later.

American-Made Plane En Route to England, 1939

PlaneCrossingBorder1939 Life Magazine 75 years ago, December 11, 1939, shows this photo of an aircraft being exported from the United States en route to its new owner, the British Royal Air Force. American neutrality prevented either American or Canadian pilots from flying military aircraft across the border. To remedy this difficulty, the planes were flown from the factory in California to Sweetgrass, Montana. From the airstrip near the border, the planes were towed by automobile over the border. The line running up the picture is the international boundary. The plane’s nose is in Canada, and its tail is in the United States.

The airport in question is truly an international airport. Coutts/Ross Sweetgrass International Airport‘s current runway, 07-26, is a 2900 foot grass strip that runs East-West along the international border. It can currently be used to clear customs entering either the United States or Canada.

Radio Coverage of Pearl Harbor

 

imgHandler

USS Shaw at Pearl Harbor. Defense Department Photo.

Contrary to popular belief, the networks never broke into live programming to announcing the attack on Pearl Harbor on December 7, 1941. The first broadcast announcement came at about 2:30 Eastern Time on CBS, during a scheduled newscast.

But you tell me that you’ve heard an announcement breaking into a symphony mid-note, with the words: “We interrupt this program to bring you a special news bulletin. The Japanese have attacked Pearl Harbor, Hawaii by air.” This was actually from a record produced by CBS in 1948. The second sentence came from an actual broadcast later in the day. You can hear the original at this link.

There was apparently no recording made of the first announcement, and there was apparently no interruption of regular programming.

A recording from Minneapolis CBS station WCCO  is available at RadioTapes.com.  While there’s no time stated on the WCCO recording, this was apparently recording during the break in the New York Philharmonic concert, which started at 3:00 Eastern Time.  Therefore, the WCCO recording probably starts at about 3:30 Eastern Time.
