Is Ham Radio Useful?

The BaoFeng UV-5RE.

Last year I got my general and technician amateur radio licences thanks to an easy to learn memory trick. But when it comes to actually using a radio I don’t have a clue. To learn more I joined my local club and took part this last Friday in a contest, using the club’s equipment, to talk to Hams worldwide. The contest involved the quick exchange of call signs. One moment I’d be talking to Japan the next Slovenia, the Azores, Brazil, Venezuela, Mexico, New Zealand–the list of countries went on and on.

I spent three hours in the club’s radio room, located in the emergency communications center at the offices of a local hospital. It was fun, but the utility of the exercise was not immediately apparent. The cell phone system is a lot more robust than it used to be and you don’t need a licence to use a phone in an emergency.

I got home from the contest around 9 pm and as I began to make dinner the windows started rattling and the house began to roll. It was an earthquake. The cats panicked and ran under the couch. Since Ham radio was on my mind I instinctively grabbed my handheld radio and immediately heard the voices of other Hams discussing the earthquake. It was then that I realized how useful amateur radio could be. Not only did I get instant information about the earthquake, but I also had access to a network of people who could help me and my neighbors in a real emergency.

The cats? Not so useful. It took about a half hour for them to emerge from their hiding spaces.

In an emergency it’s a good idea to have a radio and know how to use it. And you don’t have to be a Ham to listen to Ham frequencies. Thanks to cheap imported electronics you can now get a radio that receives and transmits on Ham bands, works as a scanner and even transmits on FRS (family radio service) frequencies–all for $40–the BaoFeng UV-5RE. The Survival Podcast did a whole episode on radios you should have in an emergency and the BaoFeng features prominently in the pantheon of zombie apocalypse communications equipment discussed on that show. I can’t speak from experience about the BaoFeng as I have a Yaesu FT-60. But, combined with a battery operated AM/FM radio, the BaoFeng would make a nice addition to your emergency supplies.

Now if only I could teach the cats to tap out Morse code.

I really enjoy learning about technologies that are basic enough that I feel like I can understand them–and maybe even replicate them. The technology of Tudor-era in England is by no means primitive, but it also is not as complex and machine-based as the tech which takes off in the 19th century and accelerates so quickly into the present era. I would be hard pressed to explain how anything around me works–from this machine I’m typing on to communicate with the outside world, to the electric light burning beside me.

Bless the BBC for making Tudor Monastery Farm (a title which I believe would not fly on American television). This is a quiet series showing three historians/archeologists at play in the Weald & Downland Open Air History Museum, trying out some of the skills they’d need to be tenant farmers to the local monastery. It has some of the structure of a reality show, but it seems that no one really wants to go that direction much, so with the exception of a bit of camera confession about the urgency of getting the peas planted before Easter, there is none of that annoying reality show faux drama. Instead, it’s just full of juicy nuggets for the appropriate tech geek.

The series is on YouTube. I pray the BBC doesn’t take it down before I get to finish it.

In the first episode alone, they cover goodies like:

  • Coppicing
  • How to make two type of fences: a hazel wattle fence and a dead hedge fence, both of which can be made with a machete and a club
  • Treadwheels: Giant human powered hamster wheels which, along with water wheels, were the engines of their time.
  • How to make rush lights out of sheep fat and rushes.
  • An almost forgotten food plant called Alexanders, which is a Mediterranean plant related to parsley, which I’ve never heard of but now want to plant in my garden.
  • Tips on calligraphy done with quills. Did you know the quill has to be almost horizontal in the hand?
  • And how to make a paintbrush out of a feather and a stick. Marvelously clever, and the secret to the fine lines in illuminated manuscripts.
  • How to make a magnifying glass out for working the detail in said illuminated manuscripts.
  • How a Tudor gentleman literally sewed himself into his clothes each day, & the mysteries and marvels of the codpiece. (I suppose that if I were transported to that era I’d eventually stop staring at the distracting cords dangling from gentlemen’s crotches. You’ll see what I mean.)
  • You get to meet one of the last working teams of oxen in England (sad!), and see what it takes to plow a field.
  • How to build and wattle and daub pig house
  • And finally, very exciting, there’s a cameo by Robin Wood, the last professional wooden dish carver in England. I’ve seen his videos (where he looks much less dorky than he does in Tudor gear) and actually have one of his bowls. He carves beautiful bowls and spoons, his only tools his hatchet, his carving knives, and a foot operated pole lathe. The foot operated lathe was in use for nearly 1000 years, but now is almost extinct. It’s a wonderful piece of technology. Robin makes it look simple, but I’m sure it takes mad skills to use.

And that’s just the first episode. Ale and cheese, blast furnaces and sheep shearing to follow!

One last take away: Because my undergraduate degree is in art history, one thing that really struck me was how much everyone in this show looked like characters out of a Bruegel painting. If you know Pieter Bruegel’s work, you might remember how all his people have this particular stocky, stuffed, oddly jointed, funny-footed sort of look. I thought this was an artistic affectation.  Turns out it’s just the way the clothes fit. Pieter, I did you wrong. You were just painting what you saw.

Extreme Low-Tech Communication

PowerSupply-large

This has to be the ultimate achievement in low-powered long-distance communication. Ham radio operator Michael Rainey, AA1TJ, transmitted a message over a distance of over 1,000 miles by yelling Morse code with his own voice into this primitive home-made transmitter, nicknamed “El Silbo.” No power was used other than that generated by his own voice vibrating the microphone (which was a re-purposed speaker).

If you want to build your own here’s the circuit schematic and more details.

And here’s Rainey, back in 2009, using El Silbo:

On a side note, can we please apply Ham radio’s level of detail and open source spirit to the world of backyard vegetable gardening?

Primitive Grain Storage Technique

Screen Shot 2013-11-02 at 11.17.50 AM

When thinking about technology, I like to play with the idea of what is the absolute minimum you need to get the job done.  This may be because I’m not very handy at building things, but yet have survivalist tendencies. So while I’m pretty sure I’ll never actually have any need for these skills, it’s fun to think about how I’d get by in a DIY world.

So I was delighted when I ran across this minimalist grain storage technique on the BBC documentary series, A History of Celtic Britain (2011), hosted by Neil Oliver of the Delicious Scottish Accent. (I am watching it on YouTube. Fingers crossed the BBC will not take it down before I finish it!)  I love this technique because while it is simple, it is far from stupid.

The technique is described by the Dave Freeman of the Butser Ancient Farm in Hampshire, where they’ve been experimenting with grain storage iron-age style (c. 400 BCE.).  Turns out all you need to do is dig a pit in the soil. The pits they dug are circular, and look to be 2 or 3 feet in diameter, and maybe 3 or 4 feet deep.

So you may ask, how can you pour grain into a hole in the ground and expect it to keep? The secret is a clay cap on the top. In the screen grab below you can see the cap and some feet for scale:

If you go to YouTube,  you can watch this sequence starting around 52:36, but what Freemen says is that when the grain goes in the pit and is sealed with a clay cap, the clay blocks out moisture, air and light. Moisture is still available at the sides and bottom of the pit, of course, especially as they are in green Hampshire.

The grain touching the sides of the pit sucks the moisture out of the soil at the edges, and uses it to attempt to germinate. The germination process sucks up oxygen and releases carbon dioxide, effectively clearing the chamber of oxygen. At that point, as Neil puts it, “Time stops.” Nothing can grow, nothing changes. The grain cache keeps for at least a year, perhaps two years, and provided a very handy safety backup for hard working iron age farmers. And some very basic appropriate tech for modern armchair survivalists to ponder.

Gourmet Foraging and Advanced Acorn Processing

acorns

It’s acorn season in Southern California. I’ve long been interested in acorns, knowing that they were the staple food of the native people who lived here, and I’ve gathered and processed them before. However, once I have the acorn meal, I’ve never known exactly what to do with it. It’s highly nutritious, but I thought (wrongly!) that it was somewhat bland, and all I could do was incorporate acorn meal into baked goods. This weekend, however, I’ve had my eyes opened to the possibilities, thanks to Pascal Baudar and Mia Wasilevich.

Pascal and Mia putting out a spread: acorn sliders, acorn and tapioca pudding, red cabbage and red onion slaw with wild juniper berries, chocolate truffles infused with white sage and dusted with dehydrated raspberry powder, plum membrillo and beer hopped with yarrow. We were there to learn about acorns, but they fed us well!

Pascal and Mia are high caliber foragers and foodies.  Check out their sites, Urban Outdoor Skills and Transitional Gastronomy, and if you live in the Los Angeles area, you’ll definitely want to experience their forages and food workshops. Their Meetup groups are The Los Angeles Wild Food and Self-Reliance Group and Foraging Foodies LA.

It’s rare to find folks who combine deep food know-how with a love of wild foods. Too often wild foods are considered mere survival foods. Pascal and Mia are using them to develop a uniquely Californian cuisine. Just check out this gallery on Transitional Gastronomy to get a quick picture of what I’m talking about.

On Sunday, Erik and I attended their acorn processing workshop, where we learned some valuable tips regarding acorn processing, and were privileged to eat the finest vegetarian burgers we’ve ever tasted — sliders made with acorns.

acorn sliders

I’ve downed a lot of veggie burgers in my time, and I’ve come to think of them mostly as excuse to eat bread and condiments. I’ve never had a veggie burger good enough to eat on its own. The acorn burgers they treated us to were not just “good for veggie” but some of the tastiest food I’ve ever encountered.

It turns out that acorns have umami qualities, that savoriness that characterizes meat and mushrooms, along with a delicate sweetness. You just need to know how to bring it out.

Mia did say that acorns have unique qualities in how they hold and absorb moisture, so she’s been learning how to handle them. Like any new food, it takes a while to learn the ways of acorns, but it’s worth it.

Here’s a recipe from Mia’s Transitional Gastronomy site for acorn timbales. If you serve these on a bun, instead of in a pool of (amazing looking!) nettle veloute sauce, you will have the acorn burger I experienced this weekend.  Do be sure to note the part where she asks you to refrigerate the mix before cooking. She told us that if the mix doesn’t have time to set up, the patties will fall apart. The recipe doesn’t specify how long to chill, but I believe she said overnight. (You could also make a log of the mix and freeze it for later, like cookies.)

I’m going to forage some acorns of my own this week and see if I can replicate those sliders. In the meanwhile, after the jump  I’m going to share some processing tips that I picked up.

Let us know if any of you process acorns,  and if you have any tips or recipes!

The Upside Down Fire

This is how I make a campfire fire now. I used to use the teepee method, or some half-assed rendition of the teepee method, and I often had trouble with such fires. They required babying, rebuilding, etc., and they burned fast. This fire is built in the opposite direction: heavy stuff on the bottom, lighter stuff on top, tinder on the very top. Basically, the finished product looks like a bird’s nest sitting on a log cabin.

This style of fire is great because it takes care of itself–build it, light it, and get on with your other chores. It lasts a long time too, as it makes very efficient use of the wood. I’ve done this many times, and it works like a charm.

The video above is a little shaky, but the technique is clear. He’s building a big campground fire in a fire ring. It’s not necessary to use so much wood–the technique scales. Here’s a link to another video showing the same method with smaller sticks and a more bushcraft-y technique.I’d recommend watching both.

The only thing I’d add to the technique in the video above is that I would lay down a larger layer of thin sticks (the 1″-2″ diameter stuff) on top of the big logs. Somehow he pulls it off with remarkably little small stuff. I found that if I didn’t have a good supply of twigs and small branches on top, the big logs in the under layers didn’t catch fire fully.

In video #2 the fellow builds a complicated teepee structure on top with his twigs. I don’t think that’s necessary, either. I mean, it’s okay, but it seems like work. You can just pile lots of little stuff on top any which way and light it.

It’s like Goldilocks. I think the first guy has too little tinder, the second guy, too much. But to each, his own. You’ll find your own way–and you’ll love this fire.

ETA: I forgot to mention that a Vaseline soaked cotton ball or a lint firestarter or some pieces of fatwood or something similar can really help foolproof the fire. Just tuck the firestarter under the small stuff. Not at all necessary, but helpful if you’re a beginner, or if conditions are bad.

Bushcraft Video

Now that we’re car-free, we may be spending even more time together then we already do. How will we keep succumbing to cabin fever, prairie style? (Prairie style means “with axes.”)

Well, while Erik obsesses on those pernicious skunks and even more heinous texting-while-driving music video producers, I’ll be laying low, watching bushcraft videos on YouTube.

We may as well give up our Netflix subscription because this YouHole is bottomless. I’ve discovered there are hundreds of men roaming about the woods with their video cameras in one hand and their survival knives in the other, ready to share their knowledge with you. And they are almost all men. I’ve only found a couple of women who put their adventures on video.

I’m not sure why this is such a male dominated field, except that it is greatly fueled by the love of pointy implements and the display and discussion of such implements–which seems a very masculine past time. But that’s generalizing, because I can attest that around our house, I’m the one with the fetish for sharp blades. And fire. And making things out of tin cans.

Anyway, there are many bushcrafters on video, but only a few rise to the top. Many–many–are hampered by poor sound quality and camera work. Their info may be good, but if I can’t hear them, or see them, I’m clicking on down the road.

In my journey of a thousand clicks, I’ve discovered many nice surprises, and I’ve learned things, too. These video makers are spread all over the world, so it’s a really nice opportunity to see different natural landscapes, and learn how people work in them. Winter survival skills may not do me a lot of good here in LA, but I do love watching video of the snowy Alps.

If you fall down this YouHole, you may find yourself gravitating toward a bushcrafter who lives in your climate zone, or one who shares your world outlook. As for myself, I’m pretty much all about watchability–yes, that’s a word–and that leads me to a couple of recs.

Picture Sundays: An Altoid Box EDC

Altoid Box EDC

Reader Ben Wison sent sent an email about his EDC (everyday carry), along some photos,

Wanted to let you see my EDCs. enjoyed your posts, and figured I would share my improvised Altoids tin. The dividers are made from empty tins cut and riveted in place. My next addition is a iron thin envelope under the mints containing a mini survival kit.

Ben promises an update once the mini-survival kit is assembled.
