Ham Radio EMP Kit, The Tactical Trash Can
HTML-код
- Опубликовано: 26 авг 2020
- Many believe the worst threat to our electronics is being damaged by an Electromagnetic Pulse. Today I show you how to prevent that damage and what I place in my EMP trash can to be ready for what may come. The trick is useing a metal trashcan AND special gasket to seal up the seams.

This videos seems to be getting a lot of views again. YES, we tested the can ruclips.net/video/o4CnecfAzng/видео.html we used a portable spectrum analyzer for attenuation readings. A cellphone and obviously radios. The results also showed that attenuation was not affected by having a ground line or NOT. Please go watch the live stream.
Are the electronics at risk if they are turned off?
Yes if plugged in
I get my new Bao Fengs delivered, go straight to RUclips and the first video I watch the guy tells me to put them in the trash can...
Lol!
When storing anything that uses batteries isn’t it better keep the batteries out all electric devices stored for long periods of time?
@@rodneyramjet8470 yes, in most cases that is good to do
@@rodneyramjet8470 Absolutely. There is zero reason to keep batteries in the devices.
😂
Josh, don't forget moisture. You aren't going to have a weep hole. Toss a few silica packets in the middle compartment.
Nope you cant do that a pin hole, or screw etc is enough to add +10dbm of signal in. -tested it.
Silica packs are a great idea. Depending on where you live condensation could be a big deal. I had the same idea as Josh, but could not seal it tight enough nor eliminate enough moisture to prevent condensation. I tried rice, but I didn't try silica.
Dry rice in a nylon stocking
@@michaelbaldwin6543 try the stones from a humidor
Josh says he's in SoCal. That means desert environment - not thinking about the consequences of moisture, because not a normal environmental factor for him. I would use it just about anywhere, though.
With the "STUFF" that's happening all over the World right now, an EMP Box makes a LOT of sense! I did a "Poor Man's" version for now until I can get a proper box made. I have put three radios away for this: My Wife's FT-4, my VX-6, and my VX-8. I have Two FT-65's. I'm planning to buy a THIRD FT-65 in the next several weeks, and then put the other TWO in Faraday Boxes as well. For my Poor Man's shield I put the radios and batteries in Separate Plastic Bags, and then Wrapped those in Aluminum Foil. Later I intend to put this in Cardboard Boxes, and THEN Everything into the Trash Can for extra protection.
Check out this new device called a EMP shield which allows you to use them while they are protected 😉
Josh, consider this point: The powergrid relies on substations, each built pretty much entirely with custom built transformers. That take about a year or two to order. So in a large EMP event, the substations will slag down and remain down until two years AFTER the transformer factories can be rebuilt. If you have a radio and license, you will be drafted on the spot for government communications. A friend of mine is on a draft board, and said very bluntly they keep hardcopy lists of all kinds of resources. Like radio operators.
Just call me Generalissimo of communications. 🤣 seriously though we spoke about this on grid-down live stream. Even a small disruption in power could have rolling waves of effect and take down significant portions of the grid.
I hear that most if not all of these sustation transformers are now made in China!
A .50 caliber or 20mm ammo can would work just as well. For a further method of sealing gaps between the body and lid of the can is to use the aluminum foil tape commonly used in HVAC duct work. Peel and stick over the seams.
I have been thinking the same thing. The only issue there is that the adhesive on the tape may act as a dielectric, preventing good connection. My boxes have a rubber sealing gasket. How about the idea of replacing that gasket with a woven copper gasket?
@@Sagart999 perhaps try out copper guitar shielding tape. It utilizes a dielectric adhesive, allowing for conductivity.
I use 40MM ammo cans, 10 gallons of space and they come with a cardboard liner (to prevent sparks originally).
About being prepared for a second EMP, if memory serves me after, lo, these many years, I believe that the military line of thinking was to expect the enemy to execute a second EMP attack in order to take out all of the transmitters that were not destroyed in the first attack. I believe that the idea was that there was a need to protect critical equipment for several days, even weeks or months, as a result.
Perhaps having an "expendable" Baofeng would be the radio to use for a somewhat lengthy period in order to protect the more expensive/useful equipment?
or making "giant" cube out of aluminium or copper mesh and put all your equipment it. would be hard to isolate antenna from radio and still keep it operational though...
@@ApocGuyactually emps wouldn’t harm most antennas
@@mycatsaliberal3848 it wouldnt unless it ha active or passive baluns . the problem is that antenna WILL pick off magnetic energy from pulse, conveying it through wires straight down to HAM radio...
@@ApocGuy honestly I shouldn’t of even said that. I don’t know enough about these kinds of antennas to even make that comment. I guess I was just thinking about other types of antennas.
Like you I wanted to have a “ miners canary” so I did put a small AM/FM weather radio solar power hand crank. But now that I’m thinking about it, I think I’m going to get a really small can just for the “canary”. Because I don’t even want to take the lid off of my big can, shortly after an EMP that may have been donated by an enemy, because certainly they will follow it up with at least the second one and possibly even a third. That’s why I have decided to move my “canary” to a separate small can so that I don’t have to open my big Can with all my electronics in it to get to the canary. Tweet!
You could also consider buying a small, cheap faraday bag for this purpose. I have a tablet bag for my Surface so I can carry it with me. I was thinking it might be helpful to have small faraday bags inside the trash can to increase the attenuation for some of the more sensitive components (such as the transceiver and its microprocessors).
I have had a EMP can for years as part of my Southern California Earthquake/Disaster kit.
- Placed a strip of conductive copper tape around the cans upper lip to help with the electrical connection between the bottom and top.
- Also placed copper tape along the inside where the handles are connected to the lid and sides. Mine had small holes at those attachment points.
- I have placed all my gear in Engpow Faraday Bags or wrapped them with foil.
- Lined mine with a rubber floor mat cut to fit bottom and sides.
- Before loading the can I lined it with two heavy duty trash bags and sealed them closed for water protection. (I live at the beach)
- Kenwood TH-G71 with USB charger and AA battery pack.
- Two Baofeng BF-888S programmed with GRMS and FRS frequencies, with USB charger. (Yes, I know...)
- Crank powered AM/FM/NOAA radio with light that can also work as a USB charger if you want to sweat out some amps.
- I placed rechargeable batteries/gear at the top of the can for easy access/maintenance. Also taped a contents list to the outside.
- Can also has solar panel, USB power packs, rechargeable AA batteries and other gadgets.
Tested can by placing my cell phone inside then called it. Failed the first time, then I added the copper tape covering the handle attachment points and it worked.
"- I have placed all my gear in Engpow Faraday Bags or wrapped them with foil.
" Respectfully, Bruce, I think you could have led with, and stopped at, that. That's all you need to do. I believe the rest is superfluous to the task.
@@davidkennerly I had the bags first, but they didn't store all my items and they were not 100% effective. So I stuck them all inside the can.
Thank you Mr. Murray this nubie Nurse knows how to start hearts not EMP. Your list is helpful.
I used a 35 gallon can, but its the same with the exception of scale. Think about using metallic tape to cover the seam down the side of the can, the seam at the bottom of the can, and the holes in the can and the lid where the handles are attached. Anyplace there is a puncture of the metal or where two edges, come together. I used the same RF gasket you have around the inside of the lid to keep from having to tape the lid on. I used a yoga mat that I cut to fit as an insulator aound the interior wall of the can and a anti fatigue mat that I cut into a circle for the bottom and top. I also put items in shield bags before putting them in the can.
Love your channel, and the way you present data (easy to understand) keep up the excellent work!
Thanks for this good video. It gives me a lot of new ideas. I prefer aluminum tool boxes for keeping my emergency rig. Most of it is square shaped, so a round shaped container seems not optimal. After watching this video, I will probably add a seal as you have shown it. Hopefully none of us experiences an EMP caused by nuclear explosion.
I have to say, after I first started looking at HAM radio and went for my first Tech test, your channel has been an enormous help and inspiration. You might even go so far as to say you're my "virtual Elmer". Thanks for the awesome info. Keep it up!
I bought one of these cans from the farm store a little while back and put an HT in there for EMP. You gave me a ton of new ideas for other items to add. The antenna mount idea is awesome!
That's a nice portable EMP set up. I have 13" and 14.1" laptops and all my old cell phones in a Faraday Defense NX3 bag, two Jackery Explorer 300 both in each their own metal ammo cases with the metal gasket upgrade to make them EMP proof. Just recently ordered four Fenix ARE-D1 battery chargers for my Eneloops, 21700 and 18650 batteries. They have 4 bay chargers but I live by the one is none rule so 4 single bay chargers with full featured display are better for my preps and can be spread into other kits if needed, plus its Fenix which I've owned a lot of their products with no failures for decades! I've got a bunch of AM/FM/Shortwave radios I like and two way radios but thinking still about what others I want to add.
One special one in my preps is the Sony ICF-F10 because it's a basic AM/FM with no sensitive complicated digital circuits to fail, sounds great and at low volume and I ran mine for 2 years on once set of D cells maybe 1000 hours. I used it every morning for a couple hours and some weekends working outside I could not believe it, some kind of efficiently fluke at low volume where it can just last. Since then I have D cell to 3AA adapters and use 6 Eneloops in it. It still goes for a year depending on how I use it. Its a 1990s style design. When they were available for $20 back in 2011 I bought 5 of them for me, friends and family it was a good one for the cost.
Saw this when you 1st made it. Have the bucket and now with Cycle 25 coming on strong I am working to make it a Thing for here. The CME potential is a fairly reasonable possibility for trouble so; great idea, Josh. Thanks. Joe
I'm just getting into HAM your videos have been so incredibly helpful. The baofeng program video you did was the best. This was full of great info.
Awesome Nate. Thanks for watching!
I will have to give this a try. I have a few radios that would need this protection. Most of my gear though is vacuum tubes, which has been proven to be impervious to EMP. Nice presentation!
The tactical trashcan? Is that what my drill sargeants used to bang on and throw to wake me up all thoss years ago?
I'm pretty sure they had trashcan throwing competitions because I remember a few times when full trash cans were thrown across the barracks bay, trash going everywhere while they're yelling at us and making use clean it up immediately. lmao good times
Oh those were the good ole' days...
Remember having to scour the inside of those trash cans till the shined like a mirror.
my dad did the same thing when I was in high school
Yes Sir, OMG, and dumping out the dead heads. Now it's pretty please get up.
And if you don't get out of bed fast enough, they throw it at you.
Great Vid!! I've been out of the radio scene for a long time!! I figured now is a good time to get some info on all the new stuff. And this really helped me to see what's going on and find out about using the new stuff!
This could be one of your more important videos imo. Thanks for sharing!
Wow. Thanks for that!
Great selection of gear and I'm glad I'm not the only one who thinks there could be more than 1 EMP if that is the scenario (Jericho, could be months apart).
Be cool to watch more of the series, too bad they cut it off without any ending. Or maybe that’s Project Mockingbird, and we are the Season 3. Wish it was joking.
Great video Josh. My suggestion is to make room for some desiccant packets. Here in So Cal it’s not such a problem, but in wet climates it is a very important necessity. I’ve not read the comments, so sorry if this a re-post.
Great idea! I'm new to the ham world going for my 1st test in 2 days. There is alot to learn. Love your videos ill be tuning in alot for ideas on radios and antennas. 73
Hope it went well 👍🏻
Josh- I think a better container would be either use a 20mm or a 30mm ammo can. My thought is, it is easier to put a square or rectangular piece of equip. in a rectangular box, plus it would be easier to use the seal on the lid. Just a thought.
I agree I love ammo boxes. The issue is the seal. You need a metallic seal instead of the rubber gasket.
That fastener on the manual screwdriver antenna is a "thumbscrew."
I scrolled down, and there it was. Gracias
I think that in an emergency situation 11m CB band should be looked at as well. There are lots of them around. Most in storage (That maybe accidentally stored EMP safe) Preppers from years ago had had the same ideas about EMP ;)
I agree. HF is nice for long distance info, but CB is the way to go for local communication because it is still being used the most.
Thanks Josh for your great even tempered videos.
My pleasure!
I don't have any radio stuff (other than a phone and an am/fm radio in my car), but this kit is extremely helpful to me. I have been wearing what basically amounts to a chastity device that is a bucket welded around my front and back. I have not been assaulted before or since!!! Thank you!
You could just switch to using smoke signals for comms. Problem solved!
A lot of good thought went into this video. Good job and thanks for posting. I'm a former EMT and I put together SABFAK medical kits. One of my philosophies is that you need to use your equipment on a regular basis to familiarize yourself with it, make sure it works, and make sure nothing is missing. I've taken up welding, and my EMP case is a custom steel box with a copper mesh seal around the top and a clasp for a lock. For my purposes a 14"x10"x12" does fine. The steel does not have to be heavy. I just keep my equipment in there, and take it out when I use it. One of my ham friends has his shack in a Faraday cage (he designs military HF and VHF equipment for a specialty contractor) and all his antenna couplings go out of one port that he can disconnect and close easily with a good seal. When he's not on the air, the whole room and all his gear is sealed up tight.
,"I think we're gonna need a bigger can."
Yes, I bought same and nothing much can put it.
So I bought a bigger one.
50 gal trash can
@@raymacdhomhnuill8018 I was thinking a 50 gal steel drum. Heavier metal...
thats what she said
In case a bigger shit hits the can.
Absolutely awesome content! Thank you ... 73!
Your video certainly made me think. Thanks!
Back in the days of film cameras there were these lead lined bags called Film Shield used to prevent damage to film from the X-ray machines at airports. They might still be available or something similar and be handy to keep a HT protected in the glove compartment of your car.
Mylar freezer bags? Metal "space" blankets...
Great video. Wrap each item in aluminum foil and put each in a ziplock bag. Separate out batteries and wrap them also. Disconnect antennas. Do not ground the can because the ground lead is an EMP antenna. Avoid ammo cans because of bad chemicals. Most important is pre-establishment of nets. Don't use callsigns because they give away your address. You may well have to defend your radio gear and everything else so use your gunsafe for guns. 73 de K6VK ##
Very nice EMP kit. This is a great idea for sure
Not a ham yet .. So I went with a President McKinley ssb cb radio , Wilson 1000 mag mount antenna, Dakota lithium power box 10 and solar panel.. 3 to 4 hour recharge time . a 400 watt inverter to plug my home propane cook range into .. It will provide heat and a way to cook/ boil water .Everything eles in the kit runs off aa rechargeable batteries/ USB changer .. lanterns , flashlights , frs radios and a skywave ssb . I bought a btech triband but at this time its worthless due to my lack of knowledge.. I just started watching your videos great video .. Thanks for all you do . Amazing info
Repeaters going down: It seems that some (likely a very few) repeater operators might have done some extra engineering effort to harden them against EMP, to the greatest degree practical. It is not impossible at all, just a lot of careful considerations.
The bucket is galvanized steel.
Looks good
I was hoping someone would say something. i had to immediately pause the vid when he said the can was made of aluminum. That would be useless as a faraday cage if it were aluminum, you need to use a steel container for it to be effective.
@@fwddodge22 Lol. Aluminum is a good conductor. They used to make wiring with it FCOL.
Great video. thanks for the advice. I thank tis could be very important way to keep emergency radio gear.
Ordered my first radio and the study guides for all 3 tests.
How about keeping everything in an individual faraday bag so when you speculatively open the can to pull one thing out they all don’t get fried, because a sun driven event would be very likely to last for hours as we commonly see in all the various events involving solarflares.
Yeah. I like that.
I'm considering building my own. And using heavy duty aluminum foil. I would create a couple of layers, and then have my electronics in small Faraday bags. That would create three layers of EMP protection. Might be overkill but I figured better safe than sorry.
Great job on the tactical trash can. I think I'll attempt to make one myself. 73!
Love your info. Thank you, and nice shirt as well
Side note, if you need more gear just get a bigger trash can. You might not be able to carry it around handheld, but you could totally fit a 100 watt solar panel and a QRO radio in it with no problem. Also if space isn't a concern, you could also totally line a foot locker with tin foil or something. Great video Josh, though I hope you never have to use that kit lol. 73 de W8IJC
I hear solar panels don't get affected by EMP. The only thing that would be effected would be the battery charger that connects to the panels. I saw a video about it. Also cars that could be from the late 90s and early 2000s could be effected too.
Outstanding and informative video! Much to consider after watching this one. When considering a more robust radio it makes me wonder if using an FT-2980 and a Diamond X-300A will reach your area form say around Irvine.
Glad it was helpful! Thank you for watching.
Hello Josh. I just found this video and I know it was 2 years ago but maybe you'll respond. I'm just now starting to think about getting into ham radio, I have watched a few videos on it and it seems to me that you pretty much got it together. The other ones I watched did also but they did not go as deep into it as you have. I appreciate you leaving the links in the description that is going to help me a lot as far as Gathering equipment and after that it's all up to me. So thanks again so much for this video I personally really do appreciate it and as an appreciation I'm going to subscribe. Since this is two years later maybe I can gather some newer information. Thanks again for the video and always remember stay vigilant.
You know your stuff man. Incredible. Amazing.... #respect
Need to use a surface conversion coating such as alodine to mitigate the aluminum oxide.
RF gasket on the lid would improve it. Copper or gold lining would be nice.
Like the shirt, with the recent balloons flying around this is a very good video.... Thanks for creating this for us all.
I just purchased 1 31 gallon that my portable solar panels fit in along with some smaller items and 3 of the 10 gallon for my solar stations,batteries and 3 6 gallon for small radios ,wiring and other. The new 31 gallon cans have a new type lid that fits better,more secure than older lids, tight fitting like the smaller cans lids all fit.
It’s my understanding that it is best to ground your Faraday cage. I’m not an expert here by any stretch, and I’ve read conflicting opinions on the necessity of grounding. It would be great if you could get some expert advice on this for your next video on this topic
Lots of very good thinking here. :) In my EMP can, I have additional layers of attenuation. I place my IC705, solar charge controller, Yaesu HT, etc in individual plastic bags. These bags are tightly wrapped in copper cloth, and each copper-cloth-wrapped bag is placed inside a larger plastic bag. Smaller holes in the large can are sealed with copper tape. Cardboard lines the larger can. My thinking is two layers of RF attenuation are better than one, and the copper cloth makes a second layer easy.
What do you do about batteries and your ability to recharge those batteries?
@@g-whiz286 I have a Bioenno 30 Ah LiFePO battery. It stays in the can as well. Two relatively inexpensive solar panels in parallel run the charge controller which charges the battery. I would like to protect the panels as well, but do not yet have a good solution because of their size. :(
@@Davidinalaska I picked up a 100 Watt foldable solar panel that is made up of ten smaller 10 Watt panels joined together in a fabric web. When collapsed, it is the size of a thick notebook and about 1/2 the size of my Jackery E300 it resides next to. The Jackery provides 300 WH of capacity and includes a 300 Watt AC inverter, a 10 Amp 13.2V (regulated) port, and a variety of USB A & C ports for small appliances. This, of course, does not fit into a 5 gallon pail. I use a 52 gallon galvanized trash can with a slightly smaller plastic trash can (handles cut off) as my insulating liner. All of the rivet holes have been soldered closed. The intention is solder the lid on (probably with solder wick) when it is full to hermetically seal it up.
Good to see you including PACE in your vids!
What is pace?
I have a similar setup, but I wanted more storage, so I used the 10 gallon can instead. :)
I am watching this with my 12 year old daughter and she pointed to the pi400 thatI got her for Christmas. I think your kit is great but my daughter pointed out that she thinks her pi400 my be better since it has everything but the mouse in a single unit. I have to agree with her.
What is a pi400. ?
stop replying to comments from TWO YEARS AGO @@rondathompson5248
Just a thought : It is possible that your pop rivet (holding the antenna support to the lid) may act as a radiator internally, it seems to protrude enough internally and would effectively act as an antenna re-radiating the EMP pulse at a reduced range of frequencies but still at high power
I was thinking the same thing plus pop rivets are hollow when the pull through breaks. It was confusing the seal around the inside of the lid then using basically pop rivets to support the strap. Open path for moisture and RFI?
Pop rivets come with sealed tops for aerospace use. Also you can put the head INSIDE, just a thought.
Too kewl, I have my kit going with a G90 also, I have it all set except for FUSES....Thanks for the clue...I forgot 73's
That alinco 2 meter rig was my first mobile. It’s nice and small, so I use it as a portable rig now.
EMPs come in waves. The first is the most intense and short lived. The ones the follow become less intense but last for a longer duration.
For EMI shielding, the smallest gaps should be no larger than 1/10th the signal wavelength.
Non nuc emp can have upto several hundred MHz freq. So gaps no larger than an half inch should be good.
You can buy copper conductive paint, spray or in a pail. Something that is not reusable, aluminum foil tape.
If the frequency is higher, maybe in the microwave wavelengths, you need specialized conductive gaskets. i.e. Parker cho-seal
true, but we're still talking about very short duration of event in any case. CME is another matter though. tnx for info on high spec gaskets, will look into it ;) .
That the 1st EMP wave is the most intense (or that it comes in waves) depends on the source. It might be true in an Atomic Bomb, but it can be more than one bomb, at variable distances, a particularly strong solar flare, a targeted EMP attack using a directional antenna...
Microwave oven with cord unplugged.
Would aluminum foil work? Where's my tinfoil hat!
@H Higgins
And hammer that lid on, and seal it with 100mph tape.
To help a metal trash can attenuate the EMP you must add some kind of seal. I prefer using a reusable seal mesh gasket on the lid that sits on the lip of the can. A future video is in the works that will demonstate the cans capability.
Isnt that galvanized steel? I thought it had to be Aluminum? At least it is for data storage like hard drives I think. I don't know much about radios.
@@ModernDecay70 to act like a faraday cage, it just have to be a good conductor, so that the pulse take the least resistance path through the shell and not into the radio, where any piece of circuit trail/wire will act like an antenna and send stray currents to all the unprotected components.
I have heard of a 'cage inside cage, inside cage' sort of arrangement where a diode connects the shells before heading to ground ... curious in all directions.
You need a large garbage can. Then you don't need to choose so little. lol
Make sure you add a bit of desiccant so it stays dry.
I have a very large old table top microwave oven for my cage....while not portable it has the sealed door you need for perfect seal. If you have a early-warning from the alert radio, you can use your existing kitchen microwave in same fashion....put your GMRs/FRs radios in there before the blast, just be sure to unplug it and leave a note on the door.....
What a killer video! Most important topic that doesn't get attention
NASA engineer here.
OK, so if you *really* want your system operational after a man-made EMP (or even a really bad solar EMP), you also need gamma ray shielding. The only way to obtain gamma ray shielding is to have at the very least 15 pounds of material *per square inch* of exposed container. For your 6 gallon bucket, that is about 2 or 3 feet of concrete (or dirt), or the same weight of water. The bottom of a swimming pool is one thought, but then the bucket has to be water pressure-proof long-term. An earthen berm can be used to store lots of sensitive equipment, plus, can act as a root cellar.
Humidity is going to be your enemy no matter what.
The reason for this is that a single gamma ray can pass through the junction of a transistor or FET and leave a permanent short circuit as it strips off the electrons on it's way through the chip. Once electrical power is applied, the chip lets all the smoke out. It can easily ruin an entire subsystem like a transceiver. This is a lot more probable than you might think. A good EMP will give close to a 100% probability of gate shorts. The thin EMP bucket/faraday-cage cannot protect against this at all.
In my case, I know where the nearest burst will be and the radiation levels across the spectrum for my location. I am preparing for the worst case X class solar burst, and the nearby (7 miles away) man-made burst. I will still keep my Faraday box just underground.
Batteries are a continuing problem - they leak and corrode everything, and have to be maintained fully charged but never overcharged.
Best of luck everyone! And, this was a great video! I learned a lot!
Thank! I appreciate your insight as well!
wont wiring be fried? so does it really matter to have a faraday system? thanks
@@4seasonsTrucker Only very long lengths of wire get damaged. The utility grid, for instance, has to deal with this (but they don't). Your car and house wiring will be fine. The electronics connected to it, not so much, but the wires themselves will easily survive any pulse that your own body can survive.
I listen to you and Canadian Prepper podcast . I will stick a baofeng and spare battery in a sealed ammo can with metal tape around the lid. I already have too many UV5rs.
Definitely! I couldn’t figure out why a pair of Baofengs *instead* of the FRS radio wouldn’t be a much better choice. That provides backup for VHF/UHF and simplex HAM comms, it also gives you a pair of radios to use as scout/recon if someone in your immediate group needs to go somewhere for food, water, etc. They can be setup to talk to FRS, GMRS, or anything else you might want.
Love the shirt! The Field Craft is Awesome!
good video and good thinking.
Remember if you're at work or not at home a microwave over can store small electronics and is a pretty good faraday cage. Just don't forget to unplug it. You don't want someone turning it on accidentally.
Will not work! put ur phone in a microwave and call it does it ring? Yes! Then it will not work
Great video! I think it is unlikely that EMP will be a problem but that doesn't mean it is impossible so this is a very good back up plan for the worst case scenario. I am more worried that the air waves will be jammed so for me I want a robust and devise coms plan, something that is hard to jam or block, I would be interested in your thought on this.
Unless you’re running spread spectrum or have many bands at your disposal, you will get jammed.
Another useful thing to add to your kit is the ZSF-YAESU-USB Yaseu USB Charger from gigaparts as another means of charging the HT.
Behrens makes 10, 20, and 33-gallon cans too. I nest a 20 inside the 33, lined with cardboard. Small stuff like batteries, cables, antenna wire etc can go in between. The most sensitive stuff goes deep inside, also insulated with cardboard.
I once watched a video where a dude sprayed Flex Seal inside of a metal can. Couple questions though, if the energy burst was large enough, wouldn't this need to be grounded to really work? Or is sufficient insulation inside enough? And how much insulation is "sufficient"?
I use a few military ammo cases. They seem to be well shielded and also seal out the weather really well. They use a rubber gasket (non-conductive) but I think the way the cover wraps around the base makes it ok, but I may want to get some aluminum duct tape (any home improvement store would have it) and start wrapping it up like a mummy.
Better off with shielding tape for guitars, conductive adhesive I think
Testing has shown clearly that the rubber gasket of ammo cans causes complete failure as a Faraday cage. Most people replace it with rolled up Al foil. And, again, I like to add a bond strap or wire between lid and can, just to be sure.
Those who have more real estate could purchase freight boxes (train car size) as a radio shed, modified for a safe house for living, faraday rated and very sturdy..can be sub grade located hillside for stable indoor environment, skylight tubes with inset solar panels for charging batteries, led lighting..etc.
I wrap both my Pelican and Gator Case Go Kits with Aluminum Foil when not in use. I also have eight 100Ah 12v Battleborne and Clone Lithium batteries, folding solar panels, misc electronics and a 2KW Propane Generator in my 2 large and 4 small metal cans with a trash bag as the middle layer. My food and survival preps are also fully stocked so I am actually alive more than a few days. Make sure you don't allow the lid seal to create any openings the EMP can penetrate.
The song is just quiet enough in the background that all I hear is the klang... Klang... Klang... Throughout the video but not loud enough to hear that it's a song. Sounds like someone's outside your house banging trash can lids
Just a thought: Use small bucket exactly the way you propose, in addition, develop a secondary unit in a large galvanized trash can for you home base. If you have to bug out, pick items in secondary to supplement the primary; dire situations pack away both…🤔
Years ago up in New England..we had an ice storm so bad..we lost power for 10 days.. lucky for me I had some survival equipment..the transistor radio keeped my sanity ..cb radio.. inverter powered my pellet stove..can food and small camping stove..all help me survive it..
THE CAN DOES WORK.. A buddy of mine and me we were in a farm store. And put a radio and cell phone in a trash can. People were watching us, and one asked what we were doing.
We explained about the EMP situation and what happens. And we demonstrated what happened to the signal reference in and out. And about Amateur Radio.
I’d like to see your calendar to find out how often you have inspect and re-charge things....I find that’s a pain with just go bags/ anything battery powered -
The advantage of the solar options is worst case scenario you can just go self-charge the batteries. Advantage of the use of AA is you can still find those anywhere after a disaster, etc.
Ham Radio Crash Course I get that, but do you check and charge things once in a while ? Or don’t touch it till it’s needed?
Nice! I was wondering, Ive heard that mylar/Reynolds cook bags can help keep out emf. If so whould it be a good idea to also line the can and tie off the bag to help with any leakage???🎛🎤🎧📡
It appears that mylar is not a good protector from EMP. I watched a video from a YT channel [ disasterprepper ] that tests a mylar wrapped box against RF emissions. Did not perform well.
Great and interesting video. You should make and sell these EMP cans! Thanks
This is a lot more portable than the typical trash can designs I've seen.
The EMP from a high level nuclear blast is unbelievably powerful. A mere aluminium or steel trash can will do nothing. Forget Faraday cage, to protect from EMP you need inches thick of copper or steel. A thin layer of steel is useless, as the magnetic component of the EMP will saturate the steel and then pass straight through. Ditto the electric component, which will generate huge currents in the shield and if the shield is not inches thick the bulk resistance of the shield will allow the EMP through.
Sorry to burst your bubble but even a small EMP will destroy huge transformers in the electricity supply grid, burning them to a crisp and melting the windings, your electronics, even disconnected and sealed in a tin can doesn't stand a chance.
Unless your car is a diesel or a very old petrol car with points, don't expect that to work either.
Do you know a resource for the field strength? I mean something that I can use to determine the V/M2 to determine what distance is safe with what shielding. There's also other considerations that help a lot unpowered equipment is much less susceptible for instance. Putting a shunt on the antenna and power connections when stored would help considerably. And there are things like putting your equipment in ESD bags in the can help as well. There is nothing stopping you from putting a can like he shows inside a larger metal can as well.
@eric thefathead most older diesels do not have any computers to run them and do not require electricity to run since it’s all compression ignition. Only time electricity was needed on my older Mercedes diesels was to warm the glow plugs when it was colder out. Mechanical fuel injection and vacuum valve to shut off the engine
Doesn't Our Government Already know that We are being Threaten w/an EMP Attack & Already have on Hand "Back Up Transformers". ? Why do we have to Wait for an "EMP ATTACK" to Build the Transformers. ? Everybody Keep's Saying, it's Gonna take a Year or 2 to Build Them. "Shouldn't We Already have a Stock Pile of them to get Everything back Up & Running Again."? I sure Hope Somebody is Taking Care of This in the Military. 🫡 Why Wait, they should be Building them NOW. !!! Common Sense. !!!
Shazam! For once I am ahead of you. Bought two small bucket size and two regular garbage can sized Behrens trash cans 5 years ago with aluminum tape to seal them. I will be very interested to see your discussion re: the seal.
@ Josh: Be sure to mention the fact that ammo cans are no good as is because the rubber gasket to waterproof/seal them leaves an opening, unless you sand off the paint from the outside edge of the can and the lid and wrap aluminum tape, or remove the gasket and apply a wire filler mesh.
replace the rubber gasket with conductive gasket?
1/2" copper woven braid grounding strap pop riveted to BARE metal between the ammo lid & ammo can's body. Again remove the paint & pop rivet to bare metal only. Route the braid on the hinge side sp you can still open the lid fully.
Since I'm here do the braid mod to the TTC too for the very same reason. Don't try t rely on just the sudo metal gasket inside the lid as was shown. And since I like copper grounding straps, run a strip between the TTC/ammo can and to a copper water pipe or your shack's earth ground for a REAL solid earth ground.

Doing the work to fix a ammo can makes the most sense to me! Radios fit better in them plus they are already tactical. That shinny bucket will get you killed! Not to mention I have plenty.
@@WW5RM Agreed. I'm bugging in.
I'll be putting my "prepped" 50 cal ammo cans in a large trash can.
You know what i use. Have used for a lot. The 'grate' looking mesh in a microwave on the door is made to keep waves from leaving the microwave. You can deconstruct a few large ones and make a web some rooms at the PMC base i am a part of are coated with this, along with professional mesh. In my 'home' the walls arw fitted with DIY EMP protection due to my line of work.
Microwave doors won’t stop and emp.
Looking forward to seeing you at HAMCATION !
I’m in town!
Or you can just get old boat anchor equipment with vacuum tubes which are immune to EMP.
they won’t fit in my trashcan. 🤣
You still need to power it!
@@MishaDaBear Just get a truck load of potatoes
Sir, I literally just found your channel and I am going to be honest...I have absolutely no idea what you are talking about. I just wanted to ask if it would be possible for you to use the Behrens 30 gallon trash can(I believe at Lowe's) so that you can fit all of that gear and possibly more in case this event takes place. I will definately start watching to learn about comms.
Sure.
Ther is a guy(caravan guy, I don't remember anymore the name) on YT that have Testet a couple flexible solar panels and all are not working after a couple years.
He suggested to use better monocrystalline panels with propper holding.
The flexible panels go defective maybe because of not enough space for heat expansion and not good enough heat disappearing, that's probably why the aluminium and Glas cased panels holding longer.
Could I recommend a different cage?
The dimensions of an M134 ammo can come out to about 7.5 US Gallons.
It is also square and made of steel.
Can be welded onto to give an antenna support, like the one you added to the trashcan.
So in conclusion, It is square so it fits in places with more space efficiency.
But because it is square more things can fit into it neatly without rounded corners.
And it is slightly larger and easier to carry with its built in handles.
World gone silent had good kits but now r not around :( they had some awesome stuff
One more comment. Ya’all better be keeping a bike or skateboard handy if you drive a car with a computer or electronic ignition. They will be yard art after this event.
Me? Well, I run a fleet of what’s in my sig pic. 😜
good ol carb aircooled boxer :) . i have vw baja bug class 5 for "rainy days" stashed in secure place . vw golf 1 and 2 would be great options too, while 3,4 are a bit more problematic (still not impossible with some knowledge and replacement parts ) ;) .
There are now emp devices for computer cars, generators,RVs, houses.
I would line that can before the cardboard is inserted with a high dielectric strength tape. EMPs can get to 50kV/M and I don’t know if that packing tape has a high enough dielectric strength to withstand breakdown at those voltages. Also using multiple shields is not a bad idea (a metal enclosure within a metal enclosure), each enclosure will attenuate the signal if the next outer shield didn’t completely block it. He didn’t ground the shield in the video, but FYI don’t ground this faraday cage if you think it will be better, that is usually only needed if there are penetrations in the outer shield or if you’re using surge suppressors rated for EMP rise times to protect hard wired equipment. The ground wire will act as a antenna and increase the voltage on the grounded shield, something you don’t want to do.
interesting josh about the EMP i was reading somethink about that the other day so good stream 73. ps they had one on that program were the toy action men were trying to take over the street and the kid fried the chips what was in them with a magnetic pulse can,t think wot it was called but
the good action man got saved because the satalite dish fell on him and it saved him fron the pulse lol good show josh
Great idea. One question though. If the EMP event is thermonuclear, will the radioactive particles in the atmosphere create nasty noise on all bands?
That is entirely possible, access to the bands would like be based on how far you wwere from the explostion.
Yes, but it will be relatively localized. One event over Antarctica won't bother the USA, and the winds aloft will affect things too, but only an EMP expert can give you specifics.
For example, the "dinosaur-killer" meteor strike in the Yucatán Peninsula spread iridium dust globally (it was that big.) but a nuke event is not that big.
Can the TTC performance be improved by grounding it? Looking forward to the show.
was thinking the same.
Grounding doesn't really do anything. An EMP pulse is so fast that there isn't much it can help.
@@HamRadioCrashCourse HRCC, many thanks. Thanks for the very informative content. Be well.
Ham Radio Crash Course Can you expand on this? It doesn't make sense to me that an EMP could out run the grounding of a Faraday cage.
@@viewatyourownrisk they have done tests the best way I can explain it is how a toroid can be a dead short on dc but it's an open where rf is concerned.
Subscribed! You had me at tactical trash can...
