Lady Bird Johnson Tours Fallout Shelter, 1961

DamascusMdFalloutShelterShown here is second lady Lady Bird Johnson touring a fallout shelter at the home of John R. Bryan, Jr., 25014 Woodfield Drive, Damascus, Maryland.

Because of his official duties as Training and Education Officer with the Office of Civil Defense, Mr. Bryan would be on duty at such time as the shelter was occupied, but he built it, at an expense of about $300 for the benefit of his wife, daughters, and mother in law.

According to the Washington Evening Star, the shelter was surprisingly cheerful looking, with yellow walls. It measured 10 by 11, with a height of six feet. Concrete blocks eight feet thick surrounded it. About 40 gallons of water were stored in the shelter, with an additional 160 gallons in tanks in the basement connected to the shelter by a hose. Food consisted largely of canned goods, with crackers and other items. A canned heat stove was on hand to heat meals, but when Bryan participated in a shelter occupancy experiment, it was discovered that this type of stove was very slow to heat the food. They also had a ratemeter and dosimeter, and as shown above, a portable radio. Little money was spent on furnishings, since most were hand-me-downs or camping gear.

The children slept on the double-decker cots, and one cot was left out during the day for seating. Another cot was unfolded at night for sleeping. A folding table rounded out the furnishings. Toilet facilities consisted of a portable toilet using plastic bags, which would be sealed in food cannisters after they had been emptied.



Motorola Playmate Junior, 1947

1942JanRadioNewsSeventy-five years ago, these youngsters, shown on the cover of the January 1947 issue of Radio News, had been especially good, since Santa had brought them, among other gifts, this Motorola Playmate Junior portable radio (Model 51M1U).

The four-tube (1R5, 1U4, 1U5, 3S4) portable covered the broadcast band, and ran off batteries or AC. On AC, the set used a selenium rectifier.

Actress Jeanne Crain had apparently also been a good girl, since she is also shown with the same model in the ad below, which noted that the set was the company’s most compact portable and had excellent signal pickup and shock-resistant tubes.  It also notes that the antenna is conveniently built in to the cover.  Since the ad mentions the film “Take Care of My Little Girl,” it must have been from about 1951, meaning that the set remained in production for quite some time.



1922 Grocery Prices

1922Jan6SeattleStarFor a snapshot of the cost of living a century ago, these grocery ads appeared a hundred years ago today, January 6, 1922, in the Seattle Star. The prices look cheap, but these are all in 1922 dollars. According to this inflation calculator, a dollar in 1922 was the equivalent of $16.54 in 2022 dollars. So you need to multiply all of these prices to get the corresponding value. So ten pounds of sugar for 57 cents is close to $10 today. Coffee was 42 cents a pound, but that’s close to $7 today. Pot roasts were 12-1/2 cents per pound, which is about $2 today, which isn’t bad. I don’t know if the supermarket today as a “fresh killed jack rabbits,” but back then, they were 35 cents each, or $5.76 in today’s money.

Jewel Model 5050: 1951

1952JanRadioRetailingSeventy years ago this month, the January 1951 issue of Radio Retailing carried this ad for Jewel’s combination table model/portable set, the model 5050.  The ad notes that whether on a table or being carried, the dial is always in a convenient position, and the sound is always pointing in the right direction.

The set operated on household current or battery, and featured a ferrite core antenna. The set had four tubes, 1R5, 1U4, 1U5, and 3V4



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.

Re-use of N95 Masks

Most N95 respirators are intended to be disposed of after a single use. However, during the first months of the COVID-19 pandemic, there were insufficient numbers of respirators for healthcare workers, and strategies for preserving the supplies were necessary. Therefore, the Centers for Disease Control published strategies for reusing masks, rather than disposing of them after each use. Those strategies were published online.

As of May 2021, that agency reported that the supply of approved respirators has increased significantly, and most healthcare facilities should resume conventional practices, namely, disposing of masks after one use.

However, with the increased availability of N95 masks, many consumers are using them for protection outside of the healthcare context. We have previously published a review of some of the available N95 and KN95 masks.

While they are now readily available, the cost might be prohibitive if a whole family wears them all day and then has to dispose of them. Therefore, many consumers may want to employ the same strategies to be able to use a single mask for more than a single use.

I rarely wear an N95 mask for more than a few minutes at a time, and it’s usually in relatively low-risk situations, such as a supermarket. Therefore, it would be extremely expensive to discard it each time. Therefore, I store the mask and re-use it at a later time. I use a procedure similar to these instructions from the North Dakota Department of Health, which show the approved procedure for re-use.  Basically, I carefully remove the mask in a brown paper bag until the next use.  This video from the University of Nebraska is a good overview of the procedure:

If you are looking for particular masks, I have used and recommend all of the following, all of which are made in the USA. You can view my full review of these masks at this link. (Note that availability varies, but all of these are usually available at Amazon. You may need to search for different colors or different size packages.

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.



Your 2022 Calendar

As you prepare for the new year, you’re undoubtedly in need of a good 2022 calendar. But there’s no need to run out and buy a new one, as you can re-use this 101 year old calendar from 1921. This one was provided courtesy of the Atlanta Tri-Weekly Journal.



William F. “Billy” White III, K5CBZ

I am not old enough to have to have worried about contracting polio, but I am old enough to have known people who suffered from the effects of polio. Amateur radio has always served as a window on the world for those with many types of disabilities, and I had the pleasure of meeting many hams who were handicapped as the result of polio.

Thanks mostly to the vaccines of the 1950s, North America saw its last case of polio in the 1970s, and children and their parents no longer had to worry about contracting it. But there were still many survivors of the disease when I was growing up in the 1960s and 1970s, and largely because I was a ham, I had the pleasure of meeting many of them.

One example was profiled in the December 1961 issue of QST, thirteen-year-old William F. “Billy” White III, K5CBZ, of Corpus Christi, Texas. White had been confined to an iron lung for eight years, and it was from that location where he spent all of his time, doing his school work, reading, and watching television. But recently, he had added to his repertoire the magic of amateur radio.

His first novice station was installed by a group of local hams, but could be operated only when he was out of the respirator, meaning that the time on the air was extremely limited. When he passed the Conditional test, a permanent solution had to be found. And thanks to the local hams, it was. It was decided that a Collins KWM-2 transceiver would be a good choice since it was relatively lightweight at 18 pounds and completely self contained. It was possible to mount the transceiver directly on the iron lung using fittings that were normally used for items such as mirrors and book holders. The set was mounted vertically, and could be removed and reinstalled in a matter of seconds.

Billy was able to operate the controls using a spatula held in his mouth. The only exceptions were the band switch and transmitter tuning. But when those were set, he could operate the set by himself.

During Hurricane Carla, Billy handled a considerable amount of emergency traffic from his station. When power at his house failed, the local hams delivered a generator, which powered both the radio and the iron lung.

Billy died in 1967 at the age of 19. But for the last six years of his life, as the article notes, “daily he traveled the airwaves, visiting friends, meeting new people, and filling his time through the magic of amateur radio.”

For people with disabilities who are interested in learning more about amateur radio and other assistive technology, we recommend you contact the Courage Kenny HandiHam Program, which has carried out that mission since 1967.



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.
