1925 Camping Radio

1925AprRadioAge101 years ago, this duo were camped out in the great outdoors. After a day of adventures, they were able to tune in some music, or perhaps listen to the news of the world, thanks to the foresight of bringing along a radio. And for the 1925 season, the April 1925 issue of Radio Age showed how to build the set.

The author began poetically by quoting a portion of The Call of The Wild by Robert W. Service:

Have you seen God in His splendors,
Heard the text that nature renders?
(You’ll never hear it in the family pew.)
The simple things, the true things,
The silent men who do things –
Then listen to the Wild –
It’s calling you.

And the best way to pull in the call of the wild is with a three-tube TRF set, as described in the article. The set was said to pull in DX, and the next step up would be a much more complex superheterodyne. This set was a moderate priced, good, substantial receiver, in a compact case containing batteries and loudspeaker.

Setting it up was simple. Just find a tree 50 feet away from the desired location, get the end of the antenna up as high as possible, and run it to the set. A tent pole would serve as a suitable mast for that end of the wire.

KaitoRadioFor modern campers, we recommend a small portable such as the one shown here. Like everything, it’s available inexpensively at Amazon. In addition to AM and FM broadcasts, it will pull in the shortwaves, meaning that almost anywhere you find yourself in the world, you’ll find something to listen to. And if you’re in North America, you’ll be able to get NOAA weather broadcasts. It’s powered by AAA batteries, but you can also run it from the built-in hand crank or solar panel. You can even use it to charge your phone or other USB device, and it has a built-in flashlight and siren. And you can even pull in the Call of The Wild.

Vitamin C in an Emergency

File:Sollip-cha.jpgAbout the cheapest way to stockpile an emergency supply of food is to get mostly rice and beans, because they will supply most of your nutritional needs at an extremely low cost. (See our earlier posts–this one, and this one, for more information.)   But that diet would be lacking in some essential vitamins.

According to the book Nuclear War Survival Skills, the first vitamin deficiency that will inflict persons living on an austere diet of rice and beans will be scurvy, due to the lack of any vitamin C (ascorbic acid). The first symptoms might appear within a month.

Fortunately, this particular effect of a famine is extremely easy and inexpensive to prevent.

The Recommended Daily Allowance (RDA) for vitamin C is 90 mg/day for men, and 75 mg/day for women. (However, these doses are probably more than necessary, since about 10 mg per day will probably prevent scurvy.)  This dose would be extremely inexpensive to stockpile a supply for many years. For example, this bottle on Amazon contains 110 tablets of 500 mg. In other words, one pill could be crushed up to meet the RDA for a family of five, with some to spare. Just three bottles would last a family of five an entire year.  This site recommends doing exactly that–grinding up one 500 mg pill and adding it to a drink, which will meet the RDA of the entire family.

Even more economical would be this jar of vitamin C powder. It contains about 226,000 mg (226 grams) of vitamin C (a quarter teaspoon contains 1250 mg). That means that it contains about 2500 servings of the RDA–it would be enough to last one person almost seven years.

Of course another option would be to store multivitamin tablets.  In many ways, that is a better option, since this would assure you of a supply of other vitamins, in addition to vitamin C. The cost is somewhat higher, but still reasonable. But the cost of vitamin C is practically zero, and it is the vitamin that you would need before any other.

We think that given the low cost, stockpiling vitamin C would be prudent for everyone. But we also realize that not everyone will be doing it. Fortunately, even if you find yourself in a food crisis unprepared, the vitamin C problem is easily solved.

If you had to forage for all of your food, it’s quite likely that you would starve to death: You simply can’t get enough calories to keep yourself alive over the long term. However, almost anywhere you live, it is quite possible to have vitamin C in abundance simply by foraging.

Your best source of vitamin C will vary depending on where you live. But for me, I have three abundant sources: dandelions, creeping charlie, and pine needles. Any of these will give an abundant supply of vitamin C. There is zero possibility that my cause of death will be scurvy.

Dandelions.

The dandelion (taraxacum) is edible in its entirety, and is an excellent source of vitamin C. The leaves are the easiest part to eat, and you can find good instructions on doing so at this link.

The roots (not unlike the root of a potato, but on a much smaller scale) might actually provide a few calories for your trouble. But just by consuming the leaves, you’ll get all of the vitamin C that you need. They can simply be included in a salad, as you would lettuce. Or, you can just eat them as they are. The veins of the leaf, especially if they are mature, can be quite bitter tasting. But if you simply remove this part by cutting out the middle, you can just put a leaf in your mouth and eat it. According to WebMD, a cup of dandelion greens contains 19.2 mg of vitamin C.  So just half a cup would provide the bare minimum necessary to prevent scurvy.

Creeping Charlie.

Creeping Charlie (Glechoma hederacea) is considered by many to be a weed, but it is found in many a suburban yard. All parts of the plant are edible, and it has a minty flavor. Again, you can simply eat the leaves, but a good way to consume it is as a tea. You can find instructions at this site.  Basically, you just put the washed plant material in a jar, fill it with boiling water, and wait an hour. You can drink the tea either hot or cold.

I’ve been unable to find the exact dose of vitamin C, but creeping charlie is said to be high in the vitamin, and it seems likely that drinking the tea on a regular basis will fend off scurvy.

Pine Needles

Eastern White Pine (U.S. National Park Service)The needles of many (but not all) pine trees are a good source of vitamin C. In particular, the white pine is an excellent source, and the needles can easily be made into a tea. You can find instructions here, but the recipe is very simple. Just add the needles to water and bring it to a boil. Then, let it steep for 10-20 minutes and strain.

In the winter of 1536, explorer Jacques Cartier and his men were suffering the effects of a disease unknown to them, scurvy.  Thanks to the Iroquois,pi the made a miraculous recovery after being given pine needle tea.

Sprouting Seeds

If you have beans stored as part of your emergency food storage, then another alternative to obtain vitamin C in a food emergency is to sprout them.    Even though the bean does not contain vitamin C, the sprouts do contain this essential vitamin.  The process for sprouting them is easy, and you can find complete instructions in Chapter 9 of Nuclear War Survival Skills.

In a food emergency, foraging for food is unlikely to satisfy many of your needs.  But it will easily provide you with one necessary nutrient, vitamin C.  But still, the cost of buying the vitamin before the emergency is so low that it’s the obvious choice.  But if faced with an emergency where you failed to prepare, remember that this particular deficiency is fairly easy to solve.

1978 Grocery Prices

1978Apr5PghFor a look at 1978 grocery prices, this ad appeared in the Pittsburgh Post Gazette on April 5, 1978.  The prices might look low, there has been a lot of inflation since 1978.  According to this online calculator, one dollar in 1978 works out to $4.89 in 2025 dollars.

This means that the ten-pound bag of potatoes for 98 cents is about $4.79 in today’s money.  And the quart of Miracle Whip for 59 cents would be about $2.89.  A pound of bacon for $1.29 would be $6.30.  If you want to compare prices, these links take you to the current listing on Amazon for the same product.

1940: Learning Code for Scouts

1940AprBLEighty-five years ago this month, the April 1940 issue of Boys’ Life contained some pointers from William “Green Bar Bill” Hillcourt for Scouts to learn the Morse Code, which was then a requirement for First Class.  The best way was to sit down with a buddy and learn the letters with a buzzer telegraph set, and the simple instructions for making such an instrument are shown below.  Then, you could continue your signaling in the great out-of-doors.

Visie-Talkie, 1945

1945AprilRadioCraft11945AprilRadioCraft2Eighty years ago today, April 1, 1945, Radio Craft magazine introduced what is properly the ancestor of the modern cell phone. It was the next logical progression after the walkie talkie and the handie-talkie, namely the visie-talkie.

The extreme miniaturization was possible due to the elimination of a needless step in television, namely, scanning. The article correctly pointed out that the human eye, just like a TV camera, contains a lens. But that’s where the similarity ends, since the TV camera has a complicated scanning mechanism. The human eye has a retina, and the article explains how this was duplicated with the use of condensinators.

Undoubtedly, the idea was put on hold due to the war, and not used again for many decades. But eighty years ago, this device demonstrated that convenient handheld video communication was possible.

Seventy years ago this month, the March 1955 issue of Popular Mechanics showed off Chrysler’s “defense minded” radios.  The dials were “especially designed to enable motorists to tune in quickly for emergency Civil Defense instructions.”  As far as I can tell, that meant that the dials had the required CONELRAD markings on 640 and 1240.



Science Fair Idea: Molecular Theory of Magnetism

1945MarPSIf Junior is looking for a fast science fair project for the deadline tomorrow, this one (and others) involving magnetism appeared 80 years ago this month in the March 1945 issue of Popular Science.

You’ll need a magnet, a compass, a needle, a clothespin (or some similar object to hold the needle) and some method of generating fire, such as a lighter.

Magnetize the needle by rubbing it on the magnet. After doing so, hold it near the compass, and the compass needle will point toward it. To demonstrate the molecular theory of magnetism, then heat the needle up to red hot. Hold it toward the compass again, and it will have no effect, or only a weak effect.

This is because the needle became magnetized because all of the molecules within became magnetized in the same direction. When the needle is heated, the atoms can move more freely, and are aligned in random directions.

EU Urges Citizens to Prepare for Emergencies

We reported a few days ago that France is encouraging all of its citizens to prepare a 72-hour emergency kit. Now, the same advice is coming down from the European Union. The X video above is from Hadja Lahbib, the EU Commissioner of “Equality, Preparedness and Crisis Management.” The recommendations are familiar to most of our readers.  Every citizen of the EU should have a survival kit consisting of:

We like to think that most of our readers are prepared in excess of these bare minimums.  But even so, it doesn’t hurt to look through a list like this, and make sure you have these items available at home, at work, in your car, at school, or wherever you might find yourself when disaster strikes.

Some of the links above are to inexpensive sources on Amazon.  Some of the links are to our prior posts where we go into more detail.  You can click here for all of our posts on the subject of emergency preparedness.

We hope there won’t be a war.  But it doesn’t hurt to take at least some minimal preparations to help you should there be one, or even a more mundane emergency.
