Elisabeth Lansdale Du Val, Ship Wireless Operator

S.S. Howard, Merchants and Miners Transportation Co.

S.S. Howard, Merchants and Miners Transportation Co.

Elisabeth (sometimes spelled Elizabeth) Lansdale Du Val (Hobleman) (1893-1987) was a ship wireless telegraph operator in the early days of radio, serving on the S.S. Howard of the Merchants and Miners Transportation Company line, in the employ of the Marconi Wireless Telegraph Company.  At the time, she was the only woman serving aboard a ship as wireless operator.

She was the daughter of Edmund Brice Du Val of 2200 North Charles St., Baltimore, and was the great granddaughter of Justice Gabriel Duvall (1752-1844), who was named to the U.S. Supreme Court by President Madison and served from 1811-35.

She passed the Commerce Department examination for a first grade commercial license on September 27, 1917.  On December 4, she began service as wireless operator on the Howard between Baltimore and Jacksonville.  She had sole responsibility for the afternoon shift, and was on watch each night.  Even though approximately fifty women held licenses, Miss Du Val was apparently the only wireless operator serving aboard a ship.

The Commerce Department had received numerous inquiries from women desiring to become wireless operators.  The department advised them that because of housing conditions on shipboard, there was hardly any demand for women as radio operators.  Instead, the department advised them to study American Morse, since there was a great shortage of landline telegraph operators due to the war, and that Western Union was providing instruction and even paying while new operators learned the trade.

On February 19, 1918, she applied to the Secretary of the Navy for a commission and assignment to a war vessel.  According to press accounts, the Navy “took the application under advisement,” but it was apparently never granted.

She married H.A. Hobelman, a 1917 graduate of Johns Hopkins University, on June 14, 1922.  Interestingly, in 1911, young Hobelman had contributed an item to Popular Mechanics for reducing stress on an anchor chain.  Mrs. Hobelman died in Maryland in 1987 at the age of 94.

Selling Portable Radios in 1939

PortableDemo1939

In 1939, Tom Carmichael, the manager of the radio and home appliance department of the Hopper-Kelly Music Company in Seattle decided that he needed to sell more portable radios. The shop’s window contained a colorful animated miniature circus, but buyers weren’t coming inside to look at radios. So Carmichael hired a pretty girl and sent her out to lure in the customers. He gave eighteen-year-old Ruth Carlyle a portable set to sling over her shoulder and sent her outside. She would inconspicuously appear near likely prospects and tune the radio to a musical program.

RuthCarlyle1939At first, most customers thought the music was coming from inside the store. But when they discovered the source, they “found it easy to learn more about the set from a girl who didn’t strain the eyes, proved pleasant to talk to and seemed just as naturally friendly as if they had known her all their lives.”

In her first three days on the job, Miss Carlyle took 57 customers by the arm and led them into the store, where salesmen on the floor closed the deal.Portable1939

The radio salesgirl appears to be the same Ruth Carlyle Miller shown in this 2010 obituary.  According to this source, the store was located at 1421 3rd Avenue.

The photos here appeared in Radio and Television Retailing magazine, September 1939.

Ahmed’s Clock

Irving, TX, Police Dept. photo, via NY Daily News.

Ahmed Mohammed is a bright 14-year-old student in Irving Texas.  He made the digital clock shown above in a pencil case, and this week brought it to school.  He showed it to one teacher who was impressed.  He then put it away in his backpack, but it started beeping during another class.

The other teacher apparently believed that bright kids shouldn’t bring unusual looking things to school.  The principal was called, and then the police were called.  Ahmed was arrested for having what someone believed to be a “hoax bomb.”

Nobody thought it was a real bomb.  Ahmed didn’t think it was a hoax bomb.  It was a clock, and it presumably told time.  He told the police that it was a clock.  He didn’t elaborate any further, because there was nothing to elaborate about.  He could have said that it told time, but presumably the cops in Irving, Texas, already knew that clocks told time.  But because he didn’t elaborate further, he was arrested.

Last month, I posted on this site the digital clock shown below in a 1975 picture.

1975Scoreboard

As you can see, this clock is just like Ahmed’s, just a lot bigger.  As you can see, there are students in the background, and they don’t appear to be freaking out because there’s a big homemade clock in the room.  The teacher wasn’t alarmed.  The principal wasn’t alarmed.  The police weren’t alarmed.  They realized that it was a homemade clock, built from plans in a magazine.  And even though it presumably had a much greater explosive potential than Ahmed’s clock, nobody was concerned.

In 1975, there was nothing wrong with a kid making something unusual and bringing it to school.  Today, a kid might get arrested for doing the same thing.  And it’s a damn shame.

Stop it, people.  Use a little bit of common sense for a change.

September 16, 1940: First Peacetime Draft

 

Seventy-five years ago, Pearl Harbor was still more than a year away.  But it was clear that it was only a matter of time before the United States was at war.  And the clearest sign came 75 years ago today, when President Roosevelt signed the Selective Training and Service Act of 1940, which put into place the first peacetime draft in U.S. history. Initially, all men between 21 and 35 were required to register. If drafted, a man would serve for twelve months, with the service to be limited to the Western Hemisphere or U.S. possessions. Under the act, up to 900,000 men would be undergoing training at any given time.

The term of service was extended beyond twelve months in August 1941, and a handful of desertions occurred when the initial one-year obligation had expired. The age limits for registration were also subsequently extended, and by the end of the war, all men between the ages of 18 and 65 were required to register.

September 15 1945 Florida Hurricane

Miami Daily News, Sept. 16, 1945.

Miami Daily News, Sept. 16, 1945.

Seventy years ago today, September 15, 1945, a hurricane made landfall in Key Largo and then swept across Miami and Homestead, Florida. It was a Category 4 storm, and winds of 145 mph were clocked at Homestead Army Air Corps Base. Most of the city of Homestead was destroyed, and at Richmond Naval Air Station, a fire ignited during the storm burned down three hangars. 1632 homes were destroyed in Florida, and there were four deaths.

Amateur radio had not yet returned to the air after V-J Day, but hams were still available to help, since they formed the core of the War Emergency Radio Service, which had been formed during the War to allow hams to provide emergency communications for both civil defense and during natural disasters.

The November 1945 issue of QST reported “September Hurricane Finds Miami WERS Ready.” The Dade County civil defense operated under the call sign of WKNW, which used hams to link ten district headquarters stations to the main control station on the roof of the fifteen-story Technical Vocational Building. A Red Cross mobile disaster unit was also equipped with radio, as were a number of privately owned mobile units. Operations began as soon as the wind subsided enough for operators to get to their designated stations.

At the peak of the storm, all lines to the civil defense headquarters were down, and the WERS station, manned by hams and powered by an emergency generator, was the only link. When the phone line to Jackson Memorial Hospital went out, one of the mobiles was dispatched to that location, and contact was re-established in fifteen minutes.

When it was clear that Homestead had suffered damage, a convoy of vehicles set out from civil defense headquartrs. The antenna at headquarters had been repeatedly destroyed, and a temporary antenna was set up inside, with only limited range. Since it couldn’t reach Homestead, one of the mobile hams in the convoy backtracked until reliable communications was established. However, with the 2-1/2 meter equipment in use, it was not possible for that station to reach all the way to Homestead. It wasn’t until the third day that a reliable link was established between Miami and Homestead, after which a considerable amount of traffic flowed.

Singled out for praise were W4NB, W4AFF, W1KVB, W4CFC, w1JMT, and W4ANP, along with two other hams who were licensed after Pearl Harbor and hence had no amateur call sign.  Of those calls, the only one where I could find any later reference was Francis W. Jenard, W1JMT, who died in 1999, according to a QST Silent Key listing.  He was a member of the ARRL A-1 Operators Club, and you can see his 1963 QSL card at this link.

Radio Goes to School, 1925

RadioSchool1925a

Ninety years ago, radio went to school, and these Kansas schoolchildren were starting their day by doing their morning calisthenics under the direction of Mike Ahearn, athletic director of the Kansas State Agricultural College. (Ahearn carefully avoided the word “exercise,” since he knew the children had been up for hours and had walked a mile or more to school.)  The same scene could be played out in any of the state’s 9000 country schools, but Ahearn was behind the microphone of the college’s radio station, KSAC in Manhattan.

RadioSchool1925bBy September 1925, when these pictures appeared in Radio in the Home magazine, a good percentage of those schools had already been equipped with receivers, and plans were in place to add a radio set to all of them.  In the photo shown here, the antenna is mounted to the school’s belfry, and it is powered by the teacher’s Model T parked outside.

The college’s director of radio extension, Sam Pickard, was doing more with radio than just morning calistenics. The sets would be in place for Kansas farmers to attend statewide radio meetings of farm organizations, and they could be used on Sundays to receive church service broadcasts.  Pickard’s vision for radio saw him appointed two years later by President Coolidge as one of the first five commissioners of the Federal Radio Commission.

KSAC had first come on the air on December 1, 1924, broadcasting with 500 watts on 880 kHz. In 1928, it moved to 580 kHz. In 1929, the Topeka Daily Capital wanted to start a radio station, and asked the college whether it could share the frequency. Since the college couldn’t afford to keep its station on the air 24 hours a day, it quickly came to terms, and was able to boost its power to 5000 watts to match the new station, WIBW.

By the 1980’s, the college had been known as Kansas State University for 30 years, and KSAC got around to requesting call letters that would match the University’s name. However, the call letters KKSU had been assigned to a ship, and even though the ship was mothballed, the owner wasn’t willing to relinquish them. So the station became KEXT (Kansas Extension) for a time until finally getting the KKSU call letters.

Over the years, the commercial station, had tried to buy out the college station, but the college refused. It wasn’t until 2001 that they had relented. WIBW had carried Wildcat football, and the University was planning on moving it to another station. WIBW used the opportunity to point out a clause its 1969 contract with the University. In exchange for allowing WIBW to carry the games, the college had been allowed to extend its operating hours by an additional 15 minutes each weekday. Finally, the University agreed to sell out for $1.5 million. The games would go to the other station, and KKSU would sign off for the last time in November, 2002,

Kansas wasn’t alone in putting radio receivers in the schools. Radio was already installed in schools in Cleveland, Ohio, and the superintendant predicted that within a few years, American schoolchildren would be receiving ten percent of their lessons by radio. Some of the big stations were involved. For example, KGO was broadcasting to the schools in Oakland, California, and WLS in Chicago was broadcasting “Uncle Ben” Darrow’s Little Red Schoolhouse into 150 schools in Cook County, Illinois, and was also popular at schools in Illinois, Michigan, Wisconsin, and Indiana.

Allied “Tiny Knight” Model B10509 & B10510, 1941

 

1941Allied4TubeIn an earlier post, we showed an inexpensive 1940 four-tube broadcast radio for $7.95 available at Walgreen’s. A modest radio such as this one would probably stay in service until the end of the War, because on April 22, 1942, the War Production board ended the production of civilian radio receivers. So if you had a radio, that’s the one you would have for the duration.

Shown here is probably one of the least expensive prewar receivers of all. This model, the “Tiny Knight” from Allied Radio is shown here in the 1941 Allied catalog, and had a catalog price starting at $5.30. It measured 6-1/2 by 4-1/4 by 4-1/2 inches and weighed four pounds, and was billed as being something that you could hold in the “palm of your hand.” It was marketed as a second radio, or for travel: “It’s so small you can pack it into any size suit-case or overnight bag and take it along when you travel.” But it was also billed as being “so low-priced that anyone can afford it.” At the tail end of the depression, it’s likely that more than a few households had a set similar to this one as their only radio. And with the ban on the manufacture of new radios, quite a few of these sets were what many families depended upon for war news.

The set’s four tubes consisted of a 12K7GT RF amplifier, 12J7GT detector, and 50L6GT audio amplifier, with a 35Z5GT serving as the rectifier. It tuned as high as 1720 kHz, making it capable of picking up police calls in many areas.

This set was a TRF (tuned radio frequency) receiver. On the same page, Allied showed its least expensive superhet, a five-tube model starting at $8.30.

The four-tube set was Allied model B10509 or B10510, depending on the cabinet.

Cave Paintings of Lascaux, 1940

Lascaux_painting

220px-Lascaux_01Seventy-five years ago today,  September 12, 1940, eighteen-year-old apprentice mechanic Marcel Ravidat was exploring the caves near his home in Lascaux, France. The war was over in the “Free Zone” of Vichy France, and young Marcel went exploring a hole he had discovered a few days earlier, opened the prior winter as an oak tree had been uprooted by a storm.

What Marcel saw hadn’t been seen in over 15,000 years. He had 220px-Lascaus,_Megalocerosstumbled upon the entrance of a cave containing some of the most spectacular cave paintings ever found. He and his friends kept the cave a secret until finally revealing its location to a teacher known to be a scholar of the other less spectacular paintings in the area. During the war, the cave was used by resistance fighters to store weapons. In 1948, the cave was opened to the public. But the breath of the constant stream of visitors, along with exposure to the atmosphere, began to take a toll. The cave was finally closed to the public in 1963.

1940: FCC Announces NARBA Rules

BC091540

Saturday, March 29, 1941, was a big day in broadcasting in the North America. At 3:00 AM Eastern Time, most of the broadcast stations in the United States had to change frequency, due to the North American Radio Broadcasting Agreement (NARBA).  The agreement was signed in Havana in 1937 and ratified by the U.S. Senate in 1938. The ratification stipulated that it should take effect a year after the treaty was ratified by four of the participating countries, Canada, Cuba, Mexico, and the United States.

The treaty was necessitated mostly by the powerful Mexican “border blaster” stations which operated on the same frequencies as U.S. stations and caused considerable interference. For example, an earlier post details how Chicago’s WCFL suffered interference from XEAW in Reynosa, Mexico.

Mexico had no incentive to deal with the situation, since it had never been assigned any “clear channel” stations on which these powerful stations could operate. The interference was Uncle Sam’s problem, and Mexico had no reason to fix it. As an incentive, NARBA gave Mexico its own clear channels on 800, 900, 1050, 1220, 1550, and 1570 kilocycles. The rest of North America agreed to keep these channels clear for Mexico. And in return, Mexico would limit its superpower stations to those channels.

The make room for the new channels, the broadcast band was expanded. It had previously run from 550 to 1500 kHz. The new band would extend from 540 to 1600 kHz, where it remained until 1990 when the top of the band was expanded to 1700 kHz.

As a result of the change, 777 of the country’s 862 standard broadcast stations got their orders to move. In most cases, the stations moved up the dial. Near the bottom of the dial, the move was generally up 10 kHz. Toward the top of the dial, most stations moved up 40 kHz. For example, WCCO in Minneapolis moved from 810 kHz to its present spot on the dial at 830.

Over the next few months, there was a great deal of activity. Transmitters would need some tuning during the early morning hours of March 29. But the most pressing matter was new crystals, and the change put a strain on the country’s crystal manufacturers. Since most stations had a spare, stations were encouraged to buy the spare from an existing station on their new frequency and to sell their own spare to a station moving in. For broadcast engineers, the night of March 28, 1941, would be a busy one.

Radio dealers could also take advantage of an opportunity for some business. It was estimated that there were ten million sets in use with pushbutton tuning. The September 15, 1940, issue of Broadcasting
pointed out that a service call to reset the buttons should cost about $2, although any listener “who can read and handle a screw-driver” should be able to do the job. As the months went on, many radio dealers sought to capitalize on the opportunity to visit customers’ homes, and perhaps sell a new set while they were there.

On this day 75 years ago, September 11, 1945, the FCC announced the new channels. The headline shown above is from the September 15, 1940, issue of Broadcasting.  It marked the start of a six-month frenzy to make the necessary changes.

Emergency Water Storage in Your Bathtub


Quick Links:


If you have advance warning of a hurricane or other emergency situation, it’s a good preparation to use your bathtub to store emergency water.  Even if you take no steps to sanitize the tub, simply filling it with water is a good idea, since you can use the water for many purposes, such as cleaning. However, unless you clean the tub thoroughly before filling it, you probably don’t want to actually drink the water from the bathtub. Also, the tub is uncovered, so the water can be contaminated. Finally, there’s the possibility that some of the water will leak down the drain. The plug is designed to hold the water long enough to take a bath. If it leaks even a tiny amount, the water could be gone in a few days when you need it.

The products shown here are designed to solve those problems, and they do. For some people, having one of these on hand could be cheap insurance. If you live in hurricane country, you should consider the problem, and having one of these might be part of the solution.

The products shown below are normally available on Amazon.   The first is the AquaPod, and the second is the WaterBob.  However, at the first hint of a hurricane approaching the U.S., they quickly sell out.  If you’re reading this before hurricane season, then it’s a good idea to order now if you think you will need one of these.  If you need a water storage solution and it’s too late to order, continue reading, since this page shows many alternatives.

For a less expensive alternative, see our later post about disposable bathtub liners such as the ones shown here:

Essentially, each of these products is the same: A large plastic bag, made of food-grade plastic, that fits inside your bathtub. The bag itself would burst under the weight of the water, but cradled by the bathtub (which was designed to hold water in the first place), the bag serves simply to keep the water sealed up safely. It also prevents the water from leaking in case the tub’s drain doesn’t have a perfect seal.

Each of these comes with a spout to fill the bag from the tub’s normal faucet. To get the water out, each of them comes with a hand pump to transfer the water to more convenient containers. So overall, each of these products is a good idea, since it gives you a convenient way to store between 65 and 100 gallons of drinking water. For some people, having one of these could be a good solution.

There are a couple of downsides, however, that you should consider. First of all, all of these are really only good for a single use. There’s no way to completely empty it. So once you’ve used it, you need to dispose of it. For that same reason, there’s really no way to test it. I’ve never heard of one of these having a leak. They appear to be well made, and it’s very likely that they will serve the intended purpose. But if it proves to be defective, there’s no way for you to know until the hurricane is bearing down, at which time it’s probably too late to get a replacement.

In addition, there is the matter of cost. While the prices are very reasonable, it’s still something that you hope you never need to use. And it’s possible that you’re reading this hours before a hurricane is expected to strike your area. If you don’t have one of these stored away, it’s probably too late to get one. So it’s important to think about alternatives.


Other Water Storage Alternatives

Obviously, clean water is one of your most critical needs during an emergency. Many emergencies could cut off your supply of tap water.  These could be a local  water line break, a hurricane, a winter storm or blizzaard, or many others.  If one of these is approaching, you should store water in all available containers, whether or not you have one of these. Your kitchen probably contains many pots, pans, and other containers, all of which were designed to hold items for human consumption. Your first order of business should be to fill them with tap water while that water is still safe to drink. Also, if you believe that the water might become unsafe at some point, it’s a good idea to turn off your water heater and turn off the intake valve. Then, you can get safe water from the tap at the bottom. (You’ll probably need to open a hot water tap on a higher floor in order for air to enter the system as you draw out the water.)

In addition, you can probably find additional containers in your recycling bin by making use of soft drink bottles. Simply clean them thoroughly and refill them with water. (Plastic milk bottles probably can’t be cleaned sufficiently to use for drinking water, although they also represent a way to store water for other purposes.)

If you are still expected to have power for a few hours, fill your refrigerator and freezer as completely as possible with water containers.  The ice and cold water will keep the other contents of the refrigerator cold, and it’s another source of clean water.

Even without a special liner, the bathtub can still be used for water storage.  You can clean it thoroughly for use.  Presumably, if you get every last bacteria, then you can simply drink the water.  However, you have no way of knowing whether you cleaned it well enough.  But even if the water is questionable, you could later purify it with bleach.

You’ll also need water for things other than drinking.  So even if you have plenty of drinking water stored elsewhere, filling the tub is cheap insurance.

If you do use the tub without a liner, you’ll want to make sure that the drain is completely closed and makes a good seal.  If you’re not sure, a piece of plastic and caulk can ensure that the tub will remain full.


Emergency Bathtub Water Storage With Garbage Bags

After filling all other containers in the house with water, you can also make your own bathtub liner in one of two ways.  The easiest would be to line the tub with clean plastic sheeting.  Then, simply fill it as usual.  It won’t be covered, but you can take care of that with additional plastic sheeting.

If you don’t have any plastic sheeting, you can also use normal garbage bags.  Of course, such a bag will quickly burst if you just started filling it with water, because it was never designed to hold that much weight.  But it will still keep the water contained.  And the tub will provide the required support.

The process of filling them is not particularly difficult.  Take enough bags to completely cover the surface of the tub.  With a normal household garbage bag, you will probably need four or five.  Place them in the empty tub, and open them up the best you can.  If there is any sharp edge in the tub, such as the drain, it’s best to cover it up with something like a washcloth.

When you have them placed, you’ll need to start filling them.  But you can’t immediately fill one of them all the way, because it won’t hold the weight.  The bag will need to be supported by the tub, and by the other bags.

Therefore, you need to take turns filling them partially, while they’re already in their assigned spot.  You won’t be able to get water from the faucet into the bags at the rear; so you’ll need to come up with another method.  If you have some kind of hose that you can attach to the bathtub faucet (or another nearby faucet), that would be easiest.  Lacking that, you’ll need to use another container.

Fill one bag part way, and then fill the one next to it to the same level.  Once you’ve filled all of the bags to the same level, go back and add more to the first one.  Eventually, all of the bags will be full, and snugly fitting in the tub.



When you pick the bags to use, make sure that you’re using ones that don’t have any kind of insecticide.  This is a case where cheaper is better.

When all of the bags are full, you can tie off the tops to keep them sealed.  Getting the water out will be slightly challenging, but not too difficult.  A pump of some kind would be ideal.  But if you don’t have one, you can simply use another container to remove water as needed.

Just as you filled them evenly, you’ll need to take the water out evenly.  You’ll need to take turns taking water out of different bags so that the water level stays about the same.

If one of the bags springs a leak, that’s not a major emergency.  You won’t be able to use that water for drinking, but it will still be safely contained in the tub for other uses.  And because the other bags are separately sealed, you can still drink that water.

waterstorageIf you need more ideas for storing water in an emergency, a good source of ideas is chapter 8 of Nuclear War Survival Skills.  Despite the title of the book, it is also an excellent source of information for practical ideas for other emergencies.  For example, the illustration here is from that book, and shows a man carrying ten gallons of water in burlap bags lined with a plastic trash bag.  You might not have burlap bags around the house, but you probably have pillowcases, and they will work as well.  You can also use a trash can or heavy cardboard box with a garbage bag as a liner.  (All of these will be heavy once filled, so you’ll want to put them where you need them prior to filling.)

Other Water Containers

Of course, if you know that a storm is coming, rather than relying on expedient solutions, it would be a good idea to have some containers designed for the purpose.  The links below show just a few of the many possibilities:
