KSTP Morse Code Lessons, 1942

1942April27BCOn this day 75 years ago, April 26, 1942, KSTP radio in St. Paul, MN, began an innovative program, as described in the article shown here from the April 27, 1942, issue of Broadcasting.

According to the report, the station was doing its part to help satisfy the great demand by the armed forces for radio operators, by conducting weekly programs designed to teach young men and women the international Morse code.

The weekly program aired Sundays at 9:30 AM, and “used drama, as sugar-coating for the lessons.” It was built around a small family, one of whom was an amateur operator. Script writing was done by Jack Hill of the St. Paul Radio Club, using lessons from the American Radio Relay League.

After the third week’s episode, the station planned to incorporate “teaser announcements” into the program in an effort to determine how many would be interested in lessons one night a week in classrooms in Minneapolis and St. Paul. The St. Paul Radio Club would furnish instructors for those courses.

The program seems to have been a great success, as reported in the September 1942 issue of QST (pp. 80-81). The fifteen minute weekly programs resulted in a total of 325 Twin City residents signing up for the classes, initially held at KSTP’s Minneapolis and St. Paul studios, with advanced students moving on to classes at the YMCA.

According to QST, transcripts of the radio broadcasts, featuring the “Strong” family, were available by mail by writing to Hill at 1138 Fauquier Avenue (now known as Bush Avenue) in St. Paul.



Station D-E-B-U-N-K, 1942

1942Apr12ChiTribSeventy-five years ago, the April 12, 1942, issue of the Chicago Tribune carried this story about a wartime curiosity on the shortwave bands, Station DEBUNK.

After the United State entered the war, the station sprung up on 7.2 MHz, and tried to pass itself off as a clandestine station operating from inside the United States.

But according to the newspaper, the FCC had confirmed what most SWL’s had already figured out, namely, that the station was broadcasting from Europe. The newspaper noted that the station was on the same frequency as the Berlin shortwave station.

The newspaper also noted that many listeners saw the hand of Freddy Kaltenbach in the station’s appearance, noting that it expressed his manner of expression and thinking. We previously wrote  (here and here) about propagandist Kaltenbach, a former Iowan of German birth.

The station was also profiled in the April 18, 1942, issue of Radio Guide, which noted that the station normally signed on to its 41 meter frequency between 7:30 and 8:00 PM Central War Time. The transmission began with an interval signal consisting of a piano playing part of the melody from the Star Spangled Banner, repeatedly playing the music for the words “by the dawn’s early light.”

The announcer then asked listeners to phone their neighbors to tune in and then played some jitterbug records. After about ten minutes, the announcer, one “Joe Scanlon” unleashed propaganda that was “anti-British, anti-American, anti-Communist, anti-Jewish, in fact, anti everything but National Socialism.”

After the diatribe, the station would sign off with the Star Spangled Banner. The Radio Guide profile noted that the station was amateurish in nature, with “the modulation as rotten as the talks.”

Announcer “Scanlon” was actually Herbert John Burgman, originally of Hokah, Minnesota.  Burgman served in the U.S. Army from 1918 to 1920, posted in Germany. In 1921, he was employed as a clerk at the U.S. Embassy in Berlin and married a German national. By 1941, he was a committed Nazi sympathizer, and declined repatriation to the U.S. along with the rest of the embassy staff, and he signed on as a propagandist for Radio DEBUNK.

After the war, he was arrested a tried for treason. The prosecution relied not only eyewitness testimony, but the recordings of the broadcasts from the FCC’s Silver Hill, Maryland, monitoring station. Despite a plea of insanity, Burgman was convicted of 13 acts of treason and sentenced to 6-20 years in prison. In 1951, the Court of Appeals affirmed his conviction. Burgman v. United States, 188 F.2d 637 (D.C. Cir. 1951).
He died in prison in 1953 at the age of 59.  He then found his way home to Minnesota and is buried in Austin, MN.

WTCN-FM Minneapolis, 1947

1947FebFM

Seventy years ago, the February 1947 issue of FM magazine carried this two-page ad from Federal, proudly showing off the transmitter and 80-foot-tall 8-element antenna of WTCN-FM, then on 96.1 MHz, (now KTCZ at 97.1) atop the Foshay Tower in Minnneapolis, then the city’s tallest building.

Thanks to the antenna gain, the 3 KW transmitter put out an effective radiated power of 25 KW, allowing excellent reception over the 30,000 square mile area shown on the map, extending from Duluth to Albert Lea.

Shown at the bottom is the Minneapolis Symphony Orchestra, whose broadcast over the station allowed listeners at home to tune in to the same brilliance and tonal quality as the studio audience.

One of the inset photos at the bottom shows Minnesota Governor Luther Youngdahl. At the bottom right, conductor Dimitri Mitropoulos is listening to his own orchestra over the air during a rehersal, which he proclaimed to sound “wonderful” and “magnificent.”



1957 TV Network

This map in the January 1957 issue of Radio Electronics, shows the status of the TV networks sixty years ago (in black), ans shows the explosive growth from the network as it had existed just six years earlier in 1950 (in red). By 1956, most American and Canadian cities were on the network, and were capable of receiving live network programming by this network of coaxial cable and microwave links. By 1957, a certain amount of redundancy was developing. For example, in 1950, Minneapolis-St. Paul got its first link, via coaxial cable to Des Moines, which was in turn linked to the nationwide network via microwave relay from Chicago. By 1957, there is a second link shown from Chicago through Wisconsin.

The diagram also shows at least two interconnections between the U.S. and Canadian networks. The U.S. Network was operated by AT&T, which had coast-to-coast service in place by 1951.

1957janradioelec2The issue also carried a listing of all stations then on the air.  The Minnesota listing here reveals that in the Twin Cities, channels 4, 5, 9, and 11 were at their familiar spots on the dial.  In Duluth, channels 3 and 6 were on the air, and Austin and Rochester each had one station.



Happy New Year!

Happy New Year from OneTubeRadio.com!

As we enter 2017, we look back 75 years to January 1, 1942, the first New Year’s Day of the War. The nation’s industry was already largely on a wartime footing, as shown by these night shift workers at the Northern Pump Company in Minneapolis. They took a half hour break to don paper caps and give 1942 a short defiant cheer. Then, they went back to work making anti-aircraft guns for the Navy.

The company was founded in 1929 by the merger of Northern Fire Apparatus Company and the Pagel Pipe Company. It moved to the Fridley plant shown here in January 1941. In 1942, it created subsidiary Northern Ordinance Incorporated. Northern Ordinance continued naval production until 1964 when it was purchased by Food Machinery Corporation (FMC), which operated the site until 1994. BAE Systems currently owns and operates the Fridley site.

Northern Pump currently operates in Grantsburg, Wisconsin.

KSTP St. Paul, MN, 1941

1941dec22bcWith America’s entry into the war, the nation’s broadcast stations were essential to inform and warn the public, and to maintain morale. As such, they were placed under military protection.

The photo shown here appeared 75 years ago today, in the December 22, 1941, issue of Broadcasting magazine.  It shows a military policeman, stationed at Fort Snelling, standing guard over KSTP, St. Paul, MN.  The caption notes that the station housed both the 50,000 watt main transmitter as well as an auxiliary 5000 watt transmitter with its own tower.  Both transmitters had been equipped for code transmission on Army and Navy frequencies.

Can America Be Bombed? November 1941


1941nov22pghpostgazSeventy-five years ago today, only two weeks before Pearl Harbor, the Pittsburgh Post-Gazette for November 22, 1941, posed the question of whether America could be bombed, and included contradictory answers:  Yes, an air raid was possible, but a Coventry-style attack on the Continental United States would be impossible, as long as America or a friendly navy controlled the Atlantic.

The article didn’t mention the Hawaiian or Philippine Islands which would be so obviously in the news in a fortnight.  However, it did look at the Pacific situation on the continent.  From Japan, air raids could possibly be made against Alaska.  If Siberia fell into enemy hands, then most Alaskan bases could be raided at will.

The focus of the article was a traveling exhibit put together by the Science Museum of Minnesota.  After being displayed in Minnesota, the exhibit was on tour, and was making its first stop in Pittsburgh.



“Vision of Peace,” 1936

1936octpopularmechanics

Eighty years ago, the October 1936 issue of Popular Mechanics featured the familiar “Vision of Peace” sculpture in the Ramsey County Courthouse-St. Paul City Hall. The sculpture had been unveiled earlier that year.

The sculpture was created by Swedish sculptor Carl Miles, and is based on his own vision of Native American spirituality, with no connection to any particular Native American beliefs. It depicts five Native Americans seated around a fire holding their peace pipes. Emerging from the smoke is an unnamed god of peace speaking to all the world.

The statute originally honored the Minnesota soldiers who died in the First World War. Subsequently, names of those who died in other wars have been added. The name “Vision of Peace” was given in 1994, during a ceremony involving the three major Indian tribes of Minnesota.

The 60 ton 38 foot statue sits on a revolving base which turns 132 degrees every 2.5 hours.

Al’s Radio Service, Owatonna, MN, 1941

1941AugRadioCraft

This ad for Al’s Radio Service of Owatonna, Minnesota, was reproduced in the Mailbag column of the August, 1941, issue of Radio Craft magazine,

along with a letter from the shop’s proprietor, Alfred J. Beauchamp. He reported being a regular reader of the magazine for eight years, during which time he saw many different service shops pictured. However, he reported that he hadn’t seen one that was as modern, up-to-date and complete as his. He asked the magazine to run his ad as a challenge to other servicemen readers. The editor obliged, but also noted that one motivation might have been “as a free ad?–Hi!”

The ad noted that Beauchamp had recently added to his staff a radio engineer and technician of outstanding ability and training. That individual was presumably Myron C. Jones, whose name appears next to Beauchamp’s in the ad. The ad noted that Al’s repaired all makes of radios, and was an authorized service station for Philco, Motorola, and General Motors car radios. While the shop did not sell radios, it was the only shop in the territory completely equipped to satisfy sound equipment needs, and had public address systems for sale or rent, as well as Dorafone office call systems and other inter-office communication systems.

The shop was located at 128 W. Pearl, Owatonna, Minnesota.
