SWLing Hurricane Florence

HWNlogoIf you have a shortwave receiver (or even if you don’t), here are some frequencies you can keep in mind for tuning in to information about Hurricane Florence.  Modern news media do an admirable job of getting the information out, but there’s something to be said for being able to tune in first-hand reports directly.

The best option is the Hurricane Watch Net (HWN), a group of amateur radio operators who will be on the air more or less continuously during the storm, taking reports from stations in the affected areas.  Since most hams are able to get on the air without commercial power, this is often the first source of reports from damaged areas.

HWN formed informally during Hurricane Betsy in 1965, and now becomes active any time a hurricane approaches populated areas.

You can tune in to HWN on  14.325 MHz Upper Sideband (USB).  An alternate frequency, which will be more active during the evening hours, is 7.268 MHz, Lower Sideband (LSB).  Conditions on 20 Meters (14 MHz) have been poor in recent days, so it’s likely that there will be more reliance on the 7.268 MHz frequency.

Health and welfare messages from those affected by the hurricane will be heard on the Salvation Army Team Emergency Radio Network (SATERN), which will meet on 14.265 MHz USB.

If you have a shortwave receiver, you’ll want to tune to these frequencies for live updates.  Even if you don’t own a receiver, there are many connected to the web, and you can listen online.  Simply go WebSDR.org, find a receiver in North America, and tune to these frequencies.

Storm forecast as of Monday afternoon. NOAA image.

Yesterday, we posted some products that may make your life easier if your area is hit by Hurricane Florence, which is approaching the Mid-Atlantic states. We provided Amazon links to purchase some of the items, since in most cases, there was still time to order online and have your purchases delivered well before dangerous conditions hit your area. If it’s not already, it will soon be too late to order online and wait for items to be delivered.

But if past experience is a guide, local stores don’t get mobbed until the last minute. There are probably already crowds, but they are still manageable.

Update:  In some inland areas, it might still be possible to take advantage of the advice given on this page for online ordering.  But as early as Tuesday, some Walmart stores in the Carolinas, particularly in the Charleston area, already closed.  Before ordering, check the status of your store at this link.  Even if online ordering is no longer available, this page will give you some ideas of hurricane supplies you might have forgotten.

And to remove much of the stress, you can still order items online at Walmart, and then pick them up at your local store a few hours later. You’ll probably still have some gaps where you’ll need to go to the store and find an item or two. But if you go to Walmart.com and select items with  “free pickup today,” you’ll be able to save yourself a lot of time.

In some areas, you can use this service for all grocery items. But almost all Walmart stores offer this service for most items, including the non-perishable items you’ll need to weather the storm. To make things easier for you, we have the following shopping list of the most common items you might need. Simply click on the link, and if it’s what you need, you can place it in your cart. If you need to look for additional items, or if one particular brand name is out of stock, you can search for it on the Walmart site.

When you’re finished, simply check out as usual, but make sure you select pickup today, and pick the most convenient store. Within a few hours, you’ll get an e-mail or text telling you that your items are ready. You just go to the store with photo ID and pick up your items from the online counter, which is usually at the front of the store.

Your individual preferences will vary, but here’s a selection of many of the items you might need to weather the storm. If the link says that the item is already out of stock, you should still be able to search for different brands of the same product.

Hurricane Preparations

Hurricane forecast as of _____. NOAA image.

Hurricane forecast as of 5:00 PM Sunday. NOAA image.

With Hurricane Florence bearing down on the Eastern Seaboard, it’s a good time to think about whether you need to top off your hurricane supplies. Even if you’re in a possibly affected area, as of this writing (Sunday evening), there’s probably still time to make a leisurely trip to the store to find everything you need conveniently on the shelf. There’s probably still even time to order on Amazon and have the things you might need delivered. If you wait until the warnings for your area go into effect, the stores will probably be mobbed with anxious last-minute shoppers, and the shelves will be bare of the supplies you need.

So if you live near the Atlantic Coast, you should think about this today. And even if you live elsewhere, it’s a good reminder to make sure you’re ready for unexpected disasters.

Here are links to some previous posts of reminders of things you’ve forgotten.  A comprehensive list of supplies is available at other sites, such as the National Hurricane Center.

Water

Having bottled water on hand is always a good idea if you know that a storm is coming.  Your tap water might be interrupted or become unsafe to drink.  But you can also store tap water, both for drinking and cooking, and also for other purposes such as cleaning.  You probably already have all of the containers you need, but if you need more, they’re still readily available.  I have more information at this link, both for suggestions on what to use that you already have, and also other containers you might consider buying.

If your water goes off, being able to take a shower can be a priceless luxury.  If you wait, it will be too late.  But if you act now, you can get an inexpensive solar shower, which I have described on this link.

You’ll probably want to use some of that water to make a cup of coffee.  You probably already own everything you need, but you might want to invest in a gadget that will make the process easier.  You can read all about it at my How To Make Coffee Without Electricity page.

Communications

The main topic of this blog is radio, and we often discuss how to communicate during an emergency.  For a detailed look at the problem, visit my Emergency Communications Primer.  At a minimum, you’ll want an AM-FM radio such as the one shown here, along with plenty of batteries.  Even if you have cellular service, cell towers often have very limited backup power, so if you’re counting on your phone as your only communications device, you might be disappointed.  A portable radio will give you access to information.

And even if cellular service is available, it won’t do you any good if you don’t have power to charge your phone.  At a minimum, you should have a car charger so that you can go out to the car to charge it up.  But another good option is  the USB charger shown here, which allows a cell phone or other USB device to be charged with AA alkaline batteries.

And speaking of battery operated devices, don’t forget to get some flashlights and batteries.  You don’t need anything fancy.  Just get a few inexpensive flashlights like this one along with plenty of extra batteries.

For information on running 120 volt appliances with the 12 volts from your car (and the limitations of this approach), please visit my power inverter page.

Food and Cooking

There’s no need to buy a bunch of expensive “survival” food prior to a hurricane.  Instead, you should simply stock up on the foods your family normally eats, with a focus on things that don’t require refrigeration and require minimal preparation.  If you buy things that you normally eat, then there’s no additional expense.  If there’s no hurricane, you simply use them up in your normal meals.  If you do want to do a bit more planning, please visit my Food Storage page for more ideas.

If your power goes out, you might not be able to cook, and having an inexpensive camp stove such as the one shown here could be a luxury that’s the envy of your neighbors.  I have more discussion of camp stoves at my coffee page.

Shopping Hints

If you’ve waited too long and it’s too late to order online, you still might consider taking advantage of Walmart‘s option to purchase online and pick up at a local store.  You’ll save time hunting down the things you need, you’ll know before you go to the store that the items are in stock, and you won’t need to wait in the checkout line.  You simply place your order online, select the option to pick it up today at a local store, and then go to the online counter to pick up your order.  If people are fighting over the last bottle of water, you’ll have the satisfaction of knowing that yours is behind the counter waiting for you with your name on it.

If you take my advice, you’ll have everything you need well before the storm hits your area.  But in case you didn’t, and you need batteries at the last minute, you can find them at a toy store.  Supermarkets will be crowded, department stores will be crowded, and they’ll all be out of batteries.  But nobody buys toys before a hurricane, and they have plenty of batteries.  So if that’s the item you need at the last minute, you’ll avoid the crowds by going to the closest toy store.

1968 Instant Battery

1968SepEE1Sixty years ago, the September 1968 issue of Electronics Illustrated carried a review of this interesting product, an emergency battery.

Batteries have a finite shelf life, so to extend it, this dry cell was sold dry. In its dormant state, it had a guaranteed shelf life of five years. When needed, you added the electrolyte, which could be any water-based liquid. In the test, the magazine used window washer fluid, but almost any liquid could be used, such as soda, or what the magazine euphemistically called “second hand beer.” After activation, the battery was good for 72 hours.

The battery was available for $5.95 from the Globe Battery Division of Globe-Union, Inc., Milwaukee. A matching lantern was available for $10.95.

Since modern alkaline batteries have a long shelf life, it’s probably not necessary to have this battery today. The best modern equivalent is probably the one shown here, which allows a cell phone or other USB device to be charged with four AA alkaline batteries.

Another option for emergency charging is s standard 12 volt USB charger.  Even if the car battery is unavailable, in most cases, these chargers consist of little more than a voltage regulator, so if they’re hooked to any source of more than five volts, they can be used in an emergency.  So if you desperately need to charge your phone, you can use one of these adapters, along with four flashlight batteries or a 9-volt battery, as demonstrated in this video:

For another emergency battery that can be made using household goods, see our earlier post.



1960 Soviet Nuclear War Planning

Vanov4
Vanov1Shown here are some eerie images of how the Soviet Union envisioned the Battle for the Fulda Gap would take place.  In the event of war between NATO and the Warsaw Pact, it’s likely that Soviet tanks would rumble through the gap on their way to Frankfurt.  And it’s just as likely that they would have been met by the use of atomic weapons to delay their advance.  As can be seen here, the Soviet tanks were expecting the atomic blasts, and planned to dig in to continue the tank battle.

Vanov2The images here are taken from a 1960 book entitled Поражающее
действие ядерного взрыва (The damaging effect of a nuclear explosion) by A.I. Vanov and G.I. Rybkin, one in the series Popular scientific library of the military publishing house published by the Soviet Defense Ministry.

Vanov3Despite the word “popular” in the series title, the book appears to be a quite scholarly look at the effects of nuclear weapons.  In fact, the book contains numerous footnotes, including frequent citations of the definitive U.S. Government treatise on the subject, the Effects of Nuclear Weapons, as shown here in the bibliography:

AM Radio Direction Finding

1958JuneRadioElecSixty years ago this month, the June 1958 issue of Radio Electronics carried the plans for this transistorized radio compass.

The circuit was nothing more than a superheterodyne receiver covering the standard broadcast band and, if desired, the longwave band. It was specifically designed for use as a radio compass. Any portable AM radio with a loopstick antenna can be used for the same purpose, although the magnetic compass mounted directly on the case made use of this one quite convenient.

The article specified that it was a worthwhile investiment for “people interested in outdoor activities such as motorboating, sailing, hunting, trapping, berry picking, camping, hiking or other activity where there is a possibility of getting lost.”

Even with this modest receiver, or even the most inexpensive AM transistor radio, the method of locating yourself is actually extremely accurate. All you need is an AM radio and a good map marked with the locations of local broadcast stations. The ferrite core antenna coil is mounted parallel to one of the sides of the case of the radio. Fortunately, the vast majority of inexpensive radios were also built this way. The antenna is very directional, and produces a sharp null when the length of the antenna is pointed directly at the station.

To use as a direction finder, the radio is placed on the map, and with the compass, the map is oriented to the map. The radio is turned until the signal fades out. At that point, the side of the radio is used as a straightedge, and a line is drawn through the radio station.

This process is repeated with a second station. The point on the map where the two lines intersect is your location.

I’ve tried this method using an inexpensive transistor radio, and the accuracy is astonishingly good. In an urban area, I can generally find my location within a few hundred yards. At night, using distant signal clear channel stations, I can determine my location within about twenty miles.

The exact location of a radio station’s transmitter (which might be different from its city of license or studio location) can be looked up at the FCC website.  Once stations are found, their latitudes and longitudes can be plotted on a map, or even on graph paper. With a bit of practice, you will be able to very accurately determine your location with very minimal equipment.

Of course, a GPS receiver will give more accurate results much more easily.  But the GPS receiver depends on GPS satellites being operational, which might not be a given in some emergency situations.  Also, if the sky is obscured by heavy foliage, a signal might be unavailable, but AM radio signals would come in loud and clear via ground wave.  As long as at least two AM radio stations are on the air, an AM radio can tell you your location quite accurately.

I’ve found that a few of the local broadcast stations seem to give an inaccurate bearing. It’s possible that some of them moved their transmitter site without telling the FCC, or possibly that station’s signal is being reflected by some nearby object. To get a precise location, I plot several bearings on the map, and ignore the one that seems not to intersect the others. The other lines are generally very close together, and I estimate my position based upon where those other lines converge.

More information about this method of direction finding can be found at this post.



Midwest Blizzard of 1949

As I write this, snow is once again forecast for my region. Since the calendar says that it’s the first day of spring, it’s likely that the snow will be little more than a temporary inconvenience.

But I was recently reminded that a snowstorm wasn’t always just a minor inconvenience, and I learned about one of the Midwest’s largest winter storms ever, the blizzard of January 2-5, 1949.

Ida McNeil, KGFX.

Ida McNeil, KGFX.

I don’t think I had ever heard about this storm until I had a comment on my post about KGFX, a one-woman broadcast station run out of the home of Ida McNeil in Pierre, SD.  As I mentioned in the previous post, Mrs. McNeil did take commercial advertising, but she viewed the station mostly as a public service.  And this is borne out from the story of the 1949 blizzard shared by reader Dwight Small:

I well remember her broadcasting during the blizzard of 1949. We were completely snowbound on the former Hugh Jaynes ranch 15 miles NNW of Pierre. She was our only window to the outside world for at least a couple of weeks. We had no electricity but the battery powered radio lasted sustained our spirits. We learned from her that there were hundreds of others in the same boat.

I did some research about the storm, and it appears that many were, indeed, in the same boat.  The winter of 1948-49 was severe in many respects, but it delivered it’s biggest punch to the northern plains in the early days of January, 1949.

The April, 1949, issue of QST describes its entry to South Dakota:

Things began on the morning of January 3rd in South Dakota, when KOTA, Rapid City’s broadcaster, let loose with the first hint that the impending storm was to be of record-breaking proportions. Unfortunately many ranchers, traveling people and others failed to hear the broadcast warnings and were totally unprepared for what was to come. It started coming down on the 3rd, and continued until about noon on the 5th. The actual snowfall was not of record-breaking proportions, but high winds, sometimes in gusts of 65 to 70 miles per hour, piled the snow into mountainous drifts, oftentimes 30 to 50 feet deep.

Many others found themselves isolated by the storm.    In 2013, the Rapid City Journal carried the reminiscence of schoolteacher Grace Roberts, who was stranded at her post in Creighton, a small town about 25 miles north of Wall. She and her four-year-old daughter made it to school, but then found themselves trapped there for 38 days. The road to the school was plowed a few times, but was quickly covered over with snow.

She reminisced in 2013 that she ate a lot of canned soup, but managed due to the kindness of neighbors, the closest of whom was a mile away. The neighbor would ride over on horseback, “and when his wife baked bread he’d bring us some bread or when he milked a cow, he would bring some milk.”

The school had a small bed, and was well stocked with coal. They also had a battery radio, and would listen occasionally, but mostly passed the time by talking and reading.

Another survivor, Everett Follette of Sturgis, like many South Dakotans, had a phone line that kept working through the storm and served as the lifeline. Interestingly, though, Follette recounted in 2009 that the family also had a battery-powered radio, “but the only station they could tune in came from Bismarck, N.D.”

Battery radio of the era, a Philco 41-841.

The family used as much milk and cream as they could from their dairy farm, but with roads impassible, they had to dump the excess. Eventually, the Sturgis creamery called about the availability of milk, and made a deal to follow a military snowblower. When neighbors learned that the truck was coming, they quickly phoned the grocery store in Sturgis to have groceries delivered.

As might be expected, hams sprang to action to deal with the communications needs of the region, as detailed in the April 1949 issue of QST. In South Dakota, when the snow first started coming down, W0ADJ and W0CZQ made arrangments with the Air Force base to maintain contact with the base at Colorado Springs, “just in case.” Hams also played a role in coordinating the massive air operations after the storm had passed. Planes were used to search for survivors and drop supplies for both humans and livestock.

Broadcast stations advised incommunicado ranchers of which marks to make in the snow to request drops of feed and other supplies.

One of the most dramatic uses of amateur radio took place in Ogallala, NE, a town of about 3000 in western Nebraska. A train was stalled in the snow west of town, and a major transcontinental highway was blocked. State snowplows managed to break through, and led a mile-long convoy of cars into town. Suddenly, the town of 3000 was pressed into service to shelter, feed, and supply communications for an additional 2000 people.

The communications duties fell upon W0LOD, the town’s only ham, whose station was limited to running 50 watts with a single 807, and only on 40 meters. Despite his modest station, “all around W0LOD–north, south, east and west–were hams with sensitive receivers, and perhaps greater power, and, as the skip ebbed and flowed he was able to sit at his operating position handling emergency traffic in unbelievable quantity much as he had been accustomed to handle routine traffic night after night. It was a 48-hour session at the key, but no heroics, no frantic ‘QRRR’–just a traffic man doing that which he likes best.”

The April 1949 QST article tells of other storms that winter, many of which overlapped each other. For example, when railroad telegraph lines went down, hams were called upon to assist the railroads in keeping te trains running. In Kansas, W0EQD didn’t even realize that his town had been cut off from the outside world. The power was out, so he got his station running on the emergency generator and checked into the Kansas Phone Net, which had traffic waiting for the phone company. As soon as he delivered the message and local officials found out he was on the air, he was kept busy for the next 48 hours as his town’s only communications facility.

Missouri was hard hit by an ice storm on January 11, and many commercial telegraph lines were down. Western Union called on hams to deliver both company and weather bureau messages. The cartoon below appeared in the Springfield (Mo.) News & Leader, and was reprinted in QST. It shows a ham being scoffed for spending so much time and money to take part in a “kid’s hobby” only to talk to people he didn’t even know. But in the next panel, after the ice hits, the same man is begging the ham to get news of his mother who was cut off from the outside world.

Solar Fire Starter

1980SolarLighterWhen I worked for Radio Shack in an earlier lifetime, one of the more interesting products we sold was the solar cigarette lighter. It was something of a novelty item, but it was also fully functional. It was nothing more than a parabolic mirror, with a little holder at the focal point.  It’s shown above in the 1980 Radio Shack catalog. The idea was to place a cigarette in the holder, point it at the sun, and after several seconds, the cigarette would start smoldering. No, it didn’t work at night or on cloudy days, but on a sunny day, it worked flawlessly.

The same simple device is now available at Amazon.  Taking inflation into consideration, it’s not much more expensive than it was back in the day, and would serve as one method of starting a fire in an emergency. Yes, you’re better off if you have matches or a traditional lighter with you, but redundancy can be a good thing, and it’s kind of fun to amaze your friends by lighting a fire using solar power.

If you don’t smoke (this is one rare case where a cigarette could save your life), then you could use other similar tinder, such as tissue paper, dry grass, or leaves. This device won’t cause anything to burst into flame, so you’ll need more tinder at the ready. As soon as whatever you lit starts to smolder, you’ll need to transfer it to a larger pile of tinder, and then blow on it until it bursts into flame.  You then keep adding larger fuel until you have a fire of the desired size.  You don’t want the fire to go out after it gets dark, because obviously you won’t be able to light another one until morning.

1961 Life Magazine Fallout Shelters

1961SeptLife1A year before the Cuban Missile Crisis, the September 15, 1961, issue of Life magazine carried a big section of civil defense advice to the nation, along with a letter to the American people from President Kennedy. He stated that war couldn’t solve any of the world’s problems, but that the decision was not ours alone.

Accordingly, he urged the magazine’s readers to carefully consider the issue’s contents to prepare for all eventualities. And the picture above shows how one family did exactly that by building one of the fallout shelters, the basic blueprints of which were included in the magazine. The magazine also told where you could write for more information, and it’s likely this family had done exactly that.

The view outside shows that this family’s town escaped the blast effects of the nuclear weapon, but the fallout had either arrived or was on the way. But life went on. Mom is tucking in the youngest child, while the older brother sits vigilantly near the entrance. (And the shelter did have an entrance, but since the original picture took up two pages in the magazine, it seems to have gotten cut off when the image from the two pages was combined). Meanwhile, the older sister seems to be fixing her hair, and the father is relaxing by lighting up a smoke in the relatively well ventilated enclosure. (In addition to the ventilation provided by the entryway, you can see four ventilation holes on the wall near the ping-pong table.)

The family shown in the picture below had even better protection, since their outdoor corrugated pipe shelter provided protection against the blast as well as fallout.   In this case, instead of going inside the relax with a smoke, it looks like the father is hoping to catch a glimpse of the fireball before slamming the door before the blast wave arrives.

1961SeptLife2

The magazine carried plans for more shelters along with estimates for their cost, as well as some other rudimentary civil defense instructions.  It also suggested the possibilities for private community shelters, such as that constructed for the group shown below:

1961SeptLife3

This shelter was in a suburb of Boise, Idaho.  Families there incorporated and bought shares for $100 each for access to this community shelter dug into a hill.  According to the magazine, the shelter had dormitories, a power plant, kitchen, hospital, and decontamination showers.  In the photo, the families were lining up in peacetime to bring in their emergency rations.

1961SeptLife4

And speaking of peacetime, there was no reason to let all of that perfectly good living space go to waste just because Krushchev hadn’t hit the launch button yet, as demonstrated in the picture above of Amelia Wilson of Vega, Texas.  The family had installed a shelter in the backyard, and Amelia seized upon the opportunity to make it her clubhouse and the perfect place to get away and chat with her friends.  But as the magazine pointed out, the shelter was ready to be put to its intended use at a moments notice, as evidenced by the air blower directly above her and the exhaust pipe running out of the ceiling.  And the radio entertains her now, but it’s also all ready to go at a moment’s notice to tune in civil defense information and warnings on CONELRAD.



Calibrating Your Watch With The Stars

1947OctPSSeventy years ago, the October 1947 issue of Popular Science showed this method of making sure your watch was accurate.

While this method would not, by itself, give you the exact time, it would very precisely tell you the elapsed time.

The method was very simple. You simply installed a piece of tin with 1/16 inch hole on some fixed location, such as the side of the building. You used it to sight a vertical fixed object, such as a lightning rod or distant skyscraper. Then, you observed the exact time that any star was occluded by the object. Since the star is essentially a point of light, it would disappear suddenly. You noted the time.

Then, the next evening, you would observe the same star. It would be occluded exactly 23 hours, 56 minutes, 4.09 seconds later–one sidereal day. In other words, the time on your watch should read exactly 3 minutes 55.91 seconds before the previous night’s figure.  (For all practical purposes, a sidereal day is 364/365 of a solar day.  This makes sense, since the Earth itself has moved 1/365 of its way around the sun in 24 hours.)

Depending on whether your watch was fast or slow, you could thus adjust the spring.

If you knew the exact time the first night, then you could also create a table showing the exact time of occlusion subsequent nights. As long as you didn’t move the piece of tin, you would always know what time it is.

This method has two applications.  After the zombie apocalypse, presumably WWV will be off the air.  The stars give you a method to keep your clock calibrated very accurately.  It could also be the basis for a very interesting science fair project.
