NOAA Weather Radio for the Deaf

Recently, on a state park Facebook group, there was a discussion of NOAA weather radios. Many people use their cell phones to receive weather warnings. But if you’re camped at a state park, it’s quite possible that you don’t have any internet or cellular service. So a weather radio is an important item to pack.  Unlike internet or cellular signals, the NOAA weather radio blankets the nation (as well as the corresponding services in Canada and Mexico).  Unless you live in an extremely remote part of the country, you will be able to pick up a weather radio signal.  To view a coverage map for your state, follow this link.)  These stations broadcast weather information constantly, and during severe weather, they transmit an alert that will activate an alarm in receivers.  For more information, you can view our earlier post.

One deaf person was part of the conversation, and he pointed out (incorrectly) that a radio wouldn’t do him much good. I corrected him, because a NOAA weather radio is very useful, even for someone who cannot hear, because weather warnings are available other than by audible means. If you have internet access, you will probably get more complete information from an internet source. But in areas with no internet access, or just as important, if the internet goes down because of the storm, then your phone won’t do you any good. In these situations, having a weather radio can be a lifesaver, and this is also true for deaf persons.

The voice on a weather radio gives more information, but during severe weather, the radio will tell you, by text display, that there is a warning, such as a tornado warning, for your county. While the additional audio information is nice, it’s not really necessary. If you know that there is a tornado warning for your county, then you know to take shelter.

Even if you do have internet access, having a weather radio is still a good idea, because it will alert you to watches and warnings, and upon seeing a warning, you can check the internet for specific details.

For a deaf person, you really need a weather radio with SAME encoding. This type of radio is programmable for your particular county, and an alarm will sound if there is a warning for your county. The text display will indicate what kind of warning it is, such as TORNADO, SEVERE THUNDERSTORM, FLASH FLOOD, etc. Most weather radios have an audible alarm that sounds during a warning. A deaf person will need one with a visual indication, such as a strobe light.

While other radios might have these same features, the Midland model WR120B/WR120EZ has these features (with the additional external strobe light).  For a deaf person to be alerted, you will also need to buy a strobe light and/or pillow shaker.

The weather radio includes an AC adapter, but it’s a good idea to keep batteries in the radio at all times, since power often goes out during bad weather. You will need 3 AA batteries for the radio, and the strobe light and pillow shaker each require two AA batteries.

The radio, the strobe, the pillow shaker, and the batteries, are all available at Amazon:

If you want to use both the strobe and the pillow shaker, you will also need an adapter cable such as the one shown below, so that you can plug both of them into the radio. (You do not need a stereo cable, but this stereo cable will work.)

If you are planning on using both, you can buy the strobe, the pillow shaker, and the adapter cable as one package deal:

You can read more information from NOAA about weather radios and the deaf at this link.

The video below, from NOAA, explains in American Sign Language how to program the WR120EZ weather radio.

Radio Apparatus Co., Omaha, 1922

1922Jul30OmahaBeeBy 1922, it was pretty clear that radio was soon going to be a phenomenon to be enjoyed by all. Retailers were starting to pop up, and Omaha, Nebraska, was no exception. This ad appeared a hundred years ago today in the Omaha Morning Bee, July 30, 1922. If you were in Omaha, then the place to be was at the southeast corner of 17th and Howard, where you would find the Radio Apparatus Company. It was no longer necessary to go out on disagreeable evenings. Your new radio could bring you music, lectures, and concerts at will. You could stop in for a demonstration, or if you called, they would be happy to arrange one in your home.



Preparing for Winter Power Outages

MrHeaterWe’ve previously written about how to prepare for a power outage.  With a little preparation, you can live reasonably comfortably without electricity, and there are numerous inexpensive alternatives to provide yourself with light, power your electronic devices, and cook your food.

News reports have warned of the possibility of power crises this summer, and most recently, Texans have been warned to conserve energy to prevent blackouts.

For many, a power outage in the summer would be an inconvenience, and mean having to go back to the days before air conditioning became universal. But a power outage in the winter could have life-threatening consequences. Of course, one can always evacuate and go to a place with power, but this might mean leaving the pipes in your house to freeze, potentially causing thousands of dollars in damage. Indeed, during the 2021 Texas power crisis, water service to a staggering 12 million persons was disrupted due to pipes freezing and bursting. When the pipes thawed, all of that water had to go somewhere, and it was often into the homes that had been without power. Plumbers were booked up solid, and building materials were simply unavailable. We had family members in Texas who had to deal with the aftermath of frozen pipes, and it served as a wake-up call. Since I live in Minnesota, sub-zero weather is common, and being without heat for just a few hours could prove extremely costly.

Of course, one possibility is to drain every pipe in the house, and then evacuate. But that’s extra work, we would need to find a place to stay, and there’s no guarantee that I would get every last drop out of the system. A better alternative is to provide a source of heat.

I decided that the best course of action would be to close off a good portion of the house. All of the plumbing in our house is in four rooms, all of which are contiguous–an upstairs bathroom and kitchen, and a downstairs bathroom and laundry room. Most other rooms can be closed off merely by closing a door. A downstairs family room can be closed off with a blanket, although it also contains a fireplace that could be used in an emergency. An upstairs living room and dining room would provide plenty of living space in an emergency.

Therefore, my plan for a winter power outage is to close off most of the house, meaning that only a relatively small area would need to be heated. For a long-term power outage, we do have a generator, and it could be used to run the electrical portion of our gas furnace. However, I would need to go in and re-wire it, disconnect it from the house, and connect that circuit to an extension cord (since we don’t have a transfer switch).

A Portable Propane Heater

simpler option, however, which does not require firing up the generator, is to use a portable propane heater.  To heat the house in an emergency, I recently acquired a Mr. Heater portable propane heater like the one shown above. Unlike many propane heaters, it is specifically designed for indoor use. In fact, in the event that oxygen levels get dangerously low, it automatically shuts off. I only have one, but I think by moving it from room to room periodically, it should keep the house somewhat comfortable, or at least keep all of the pipes above freezing.  Obviously, it’s not going to provide as much heat as the normal furnace, but I think it’s large enough for the bare minimum of emergency heating.

Since we have a gas water heater that does not require any electricity whatsoever, my plan is to keep all of the faucets dripping with warm water. The moving water will keep those pipes from freezing, and a certain amount of heat will be radiated from the hot water pipes. In addition, the gas stove in the kitchen will be used for cooking as usual, and the “waste” heat from this process will help warm the house.  While possible, loss of natural gas is much less common than loss of electricity.  The water heater will keep operating seamlessly without electricity, but the kitchen stove will require matches to light.  (The oven will not work without electricity.)

The propane heater needs fuel. It’s designed to use the small one-pound cans of propane, like the ones shown here. For occasional use, these are quite handy, but they also get expensive, and they probably wouldn’t be available in an emergency.

According to this site, a one-pound bottle will last about 5 hours on low, or about two hours on high. So if was run constantly, it would require, at a minimum, about 5 bottles per day, which would get expensive very fast.

Using Less Expensive 20 Pound Propane Bottles

Propane in 20 pound bottles is much cheaper. And those large bottles are available at many convenience stores, hardware stores, and even the local drug store.

In normal circumstances, these propane exchange retailers aren’t the greatest deal.  Generally, you pay for 20 pounds of propane and only get 15.  So during normal circumstances, there are cheaper places to buy propane.  But if an emergency is looming, the price isn’t too out of line, and there are many dealers close to home.  In our case, we always have one bottle on hand, almost full, mounted on our camper. Others routinely have these on hand for their barbecue. According to that same website, 20 pounds of propane will last about 100 hours on low, or 40 hours on high. In other words, the single propane bottle we always have on hand will last between 2 and 4 days.  And if I acted fast enough, I would be able to buy more very conveniently.

Refilling Propane Bottles

There are two ways to use the larger bottles with the Mr. Heater. The cheapest is to buy one of the little gadgets shown here, a propane refill adapter.  What this allows you to do is to refill the one-pound bottles from the larger 20 pound bottle. It’s a bit of a cumbersome process, since you need to hook them up, and then turn the large bottle upside down for the propane to drain into the small canister. So it’s not ideal, but it’s cheap, and it works.

I should point out that this method is not entirely legal. In particular, you are not allowed to transport a “disposable” bottle, certainly not across state lines, after you have refilled it. That’s because the small bottle is designed for one use, and it might not seal up again. But for emergency use, it seems like a very small risk.  Even though I’ll use the method shown below, I also have one of these refill valves.  In some cases, it’s handier to use the small bottles, and I might want one of them for a propane lantern or stove.  And if the hose shown below gets broken or misplaced, the refill kit is a good backup.

The better method, it seems to me, is to use the relatively inexpensive hose shown available from Mr. Heater. This is designed to be used with the Mr. Heater, and lets you run it directly from the larger 20 pound bottle. You no longer have to worry about the inconvenience and slight danger of refilling the bottles at home. The only downside is that the heater is no longer as portable, since the 20 pound bottle of propane needs to be lugged around.  You can also buy the heater along with the hose, which is what I did.

Now that we have the Mr. Heater Buddy, I feel more secure about winter power outages. While they would still be an inconvenience, it would no longer be life threatening. If such an event appeared likely, I would purchase one or more extra 20 pound bottles of propane, which are available at two stores within walking distance of my house. They could be sold out, but if I act fast, I can probably secure one. And even if I don’t, I always have at least one, which will provide heat for 2-4 days.

I have both the adapter hose to run the heater from the large container, and also have the refill adapter to re-use any small cans we have. (And we usually have at least a couple of those on hand.)

In anticipation of a power outage, I would set the heat higher than usual, and prepare to seal off unused rooms. If the power went out, I would seal them off, and also set the faucets to dripping. At that point, I would fire up the propane heater and move it as needed to the four rooms where the heat is needed.

I won’t know for sure until it happens, but I’m confident that this strategy will keep my family relatively comfortable, as well as preventing any damage to plumbing due to freezing.

Indoor Kerosene Heaters

Another option, with which I am less familiar, is a kerosene heater, such as the  this one.  Kerosene heaters seem to be more expensive than their propane brethren, but they could also be a good solution. For most people, the liquid kerosene fuel is easy to store. In my experience, it’s not for sale as many places as propane, but if you stock up before the emergency, this might be a good option.

Safety First

Whatever fuel you choose, keep in mind that you need to buy a heater that is safe for indoor use. Some of them are, but most are not. All of the heaters shown on this page are designed for indoor use, and are safe to be used in the house.  (The ones designed for indoor use have an important safety feature missing in outdoor heaters.  They contain an oxygen depletion sensor which will shut them down automatically if the oxygen level gets too law.  For this reason, however, the indoor units will not work at high altitudes.)

And having a battery-powered carbon monoxide detector is always important, but it takes on special importance when using new appliances to heat your home. It’s cheap insurance.

1953 Grocery Prices

1953Jul28PghPressFor a snapshot of grocery prices in 1953, this ad appeared in the July 28, 1953 edition of the Pittsburgh Press.  (You can click on the image above for a larger version.)

These prices look low, but there’s been a lot of inflation since 1953. According to this online inflation calculator, one dollar in 1953 is the equivalent of $11.10 in 2022 dollars. So the 25 pound bag of flour for $2.05 would be the same as $22.75 today. You can compare that to the link below, which shows today’s price for 24 pounds:

The price is pretty close, but the 1953 version contained a silver teaspoon inside the bag! And I’m guessing that more households bought flour 25 pounds at a time than they do today.

Ground beef was 2 pounds for 89 cents, which works out to $4.93 per pound in today’s money. How does that compare to today’s price below?

If you were doing your family’s grocery shopping in 1953, what would you buy? And do you think you would spend more time in the kitchen preparing dinner than you do now?

Upgrading Portables with Selenium Rectifiers: 1947

1947JulyServiceSeventy-five years ago this month, this ad from Federal encouraged radio dealers to make some extra profit by upgrading their customers’ portable radios. Most such sets operated off batteries as well as standard household current. The radio itself had four tubes, along with an additional rectifier tube for use at home, in this case a 117Z6. The low-voltage tubes came to life almost immediately, but the rectifier took some time to warm up. By replacing it with a selenium rectifier, this problem was solved. And even though selenium rectifiers are famous for their catastrophic failures (which produce malodorous and toxic fumes), they probably lasted longer than the tube, and probably outlasted the radio in most cases.

The age of selenium rectifiers lasted through the 1960’s, when they were replaced by silicon diodes.

The ad appeared in the July 1947 issue of Service magazine.



Radio the Right Way and the Wrong Way: 1922

1922JulPSWith radio, as with everything, there’s a right way and a wrong way of doing things. A hundred years ago this month, in the July 1922 issue of Popular Science, Armstrong Perry gives some pointers on how to set up your radio receiving station the right way, and he includes the examples shown above. He concedes that the second station might be highly efficient, but from not planning things out right from the beginning, it is “no ornament to the household.”



1922 Crystal Set

1922JulSI2A hundred years ago this month, the July 1922 issue of Science and Invention carried the plans for this, which the magazine called the “simplest radio receiver.” The plans had been sent in by Leon Webster, who won $50 in the process, as the third-place winner of the magazine’s radio design competition.

According to Webster, the set could be constructed by a twelve year old boy, and a great deal of pleasure could be obtained. All that was needed was an outside antenna and ground, a tuning coil, condenser, and detector.

The condenser consisted of one from a defunct Model T spark coil, and the detector was a piece of galena or silicon. The coil, as shown here, was homemade on a piece of wood. The set would work with an old telephone receiver, but for better results, a 1000 ohm headphone was the better option.

Prediction of Television: 1922

1922JulySIA hundred years ago this month, the July 1922 issue of Science and Invention made its prediction of what television would look like. The accompanying article, written by Hugo Gernsback, got most of the technical details wrong. But the artist’s conception, by illustrator Howard V. Brown (1878-1945) doesn’t look very different from the sets that started showing up in American homes a quarter century later.  If the style looks familiar, it’s because we’ve seen Brown’s artwork before.

 



Seaman’s Aid Society Radio Doctor: 1922
