It is VERY IMPORTANT to place the fuse as close as possible to the power source, especially in mobile installations. One of it's primary purposes, except to protect the radio, is to prevent a short circuit of the power lead from causing a FIRE, especially where the wiring comes through the firewall into the vehicle, which brings up another topic, the wires should be protected where they pass through the firewall with a rubber grommet or protection sleeve.
Josh, you're a national treasure, my man. Eleven months later, and this video is still tops.
Thanks David, I appreciate that!
I love this video, people talk about their equipment all the time but I dont see people talking about power supplies much at all
Thank you! Give it the 👍
This is a really helpful video Josh, even two years later. The power aspect is one of the most important parts of SHTF radio gear. Many videos go into ham emergency kits, but fail to really cover the battery solutions that could work, especially when there is no power available at all. Glad that LiFePO4 batteries have come down in price since the video was made. Good job!
For automotive installation of HF 100 watt radios---use 12 gauge or even better 10 gauge wire and run it directly to the battery with fuse or breaker in series. Add an appropriately sized relay and switch the relay from key switch if you want the radio to power down with key.
Josh, you’re a treasure trove of information, so, thank you!
My pleasure!
Excellent vid. Thanks so much!!! Also I just checked out your amazon store. Love how you have it laid out… makes it easy to understand what we need.
Thank you!
Very good video Josh❗️it’s definitely an advantage to have several different options to power your radios. 73. KV5P
Wanted to say thank you for this video. It helped me figure out what I needed to power the SAR radio trailer I get to build out. (The team I am on is a small one in WV and I'm doing their tech/radio stuff for them.)
Awesome! I’m glad it helped!
Focus you Duck!
Great video man, thanks for the upload.
Great video!
Very helpful. Thanks
Great video thank you
Great video josh thank you
Great video Josh, this topic had me baffled for a long time and it is so important too. Wrong amperage/voltage etc… can be very costly to us Hams. Just when I think I’d worked it all out you make a great video explaining it, lol. At least you have confirmed I had grasped the subject correctly. All new Hams should see this Video, 5 🌟 73 de 2E0TWD
Thank you!
Nice video Josh.
I recently purchased an STP 1330 it's got really good numbers on it and I love that it's got the cigarette adapter right there for other shop needs. Anyone have any thoughts about this unit? It's only 30 amp but it is a switching power supply it's regulated and it specifically made for communication equipment.
And yes the 200 amp hours of batteries got to be a bit heavy.
Team Replay for the win!♡♡♡ appreciate your work hamFam :)
THANK YOU FOR THE CALCULATOR
I've used so many different external portable batteries and my favorite are definitely Bioenno batteries for the power/dollar.
I'd love to hear what charge controllers you think are good - also maybe different solar options.
Maybe you already have info on that.... I'll have to look
Thanks for all the info. You cover almost all my questions!
Getting ready to build a portable shtf communications box.
Yes, LiFePO4 is more expensive up front, but the average lifespan of a lead acid battery is 600-800 cycles (assuming you don't run it down below 50% which will kill it). A lifepo4 battery is good for 3000 to 8000 cycles, so it has 10 times the lifespan. If you baby it and only charge from 20% to 80% it will last for decades. Lifepo4 is cheaper in the long run, and safer.
Good points! 👍👍
How many times will you actually drain the battery so much would also be a consideration.
Why not lipo? They're much cheaper than lifepo
Love you charge with solar lots of testing done
You have done a great job covering power for our radios.
Thanks Josh, great information.
Thank you
Sure thing!
Thanks Josh. Have you found a good way to charge your Bioenno using the vehicle? It would be handy to charge one LiFePO4 battery while using another, but most chargers want 120VAC. Seems like overkill to use an inverter.
can use power bank ? i was thinking carrying around.
Nicely done Josh! 73 de K1JHS
Hi Josh,
Excellent video with great info. I've been using a Samlex SEC-1235 power supply for my FT450, Amertron RCS-8 remote coax switch, and West Mountain Radio ClearSpeech CLRdsp for three years with a hiccup. You and the family stay safe. 73 WJ3U
Makes me feel fortunate that my vehicles cig lighter is straight off the battery using using around 8 gauge wires straight from the battery and has a 30amp fuse. Never had any issues. The most power i run mobile is only 50 watts so my setup serves me well.
Any all in one power stations - jackery, goal zero, etc, that would work for ham radio? I know they're based off watts and not amps, but looking to build one out of a lifepo battery costs more than an all in one. Bioeno makes a box but doesn't have the solar charge controlled built in.
I lucked up with a switching power supply it is very quiet. I put it on a scope and it has a really clean power output. It was a cheapo so was a gamble.
Most all switching power supplys produce noise but the high speed switchers are easier to filter and the higher frequency the smaller the caps needed to filter them.
thanks Mike fantastic video 73 from kb2uew
I’m Josh. 😵
Hi. Can you please advise for a battery for the anytone 578 for a manpack? I was looking into 12v lithium polymer. Would those work? I'm really new. Thanks
Some of the upgrade batteries for the Baofeng radios have a DC input jack on the battery themselves (as well as the normal charge pads to use the stock Baofeng charger). There's also the battery packs that take AA batteries, as well as the one that contains no batteries but allow you to plug into the DC port in the car.
There's also the far more expensive Battleborn lithium batteries if you're using solar in the shack to power equipment.
OK, I have a question about vehicle power. The typical car/truck, the battery isn't far away from the radio. However, in a semi truck there's a lot more real estate between the battery and ground to the radio. The batteries are usually mounted in one of three locations; step box under the door, battery box under the sleeper (not very common anymore) or in a battery box mounted between the frame rails usually a foot or two behind the back wall of the sleeper. Would the extra distance of power wire effect the radio? Now most trucks do have red/black screw poles (12v) for CB somehere on the dash or overhead CB din and works just fine but I'm not to sure if it will be sufficient for a Amateur radio.
Also I am finding a bit of conflicting information on Amateur and CB antenna mounting and spacing. I would like to keep the CB up and running at all times for traffic information but don't want the HAM interfering and bleeding over into the CB. Any ideas?
How RF noisy is the toolKitRC power supply?
Is your pointing assistance tool an Abbree??
Yeah. The sharp one.
@@HamRadioCrashCourse Now I got a ToolkitRC P200 in the shopping cart.
@@HamRadioCrashCourse it's sharp and to the point......
I run my base with one of those switching power supply @11:42. 😁
@Ham Radio Crash Course. I Have a 20 Amp 13.8VDC Linear Regulated Power Supply highly stable, high quality. My question is on the unit it says 20 AMPS Constant / 22 Amps Surge. What is the 22 AMP Surge for? And What does it do? Thank You. Love all the info from this channel.
Surge implies short term draw. Not continuous. It would depend on the device you run on the supply of that even matters for you
hello, I'm looking for a way to store my radio presets on my boat when I cut off power to the helm. Do yo know if I can do this with a similar battery? NOONE has a video out there showing this process. I think it would be very beneficial. I don't think the radio needs much juice to "remember' those presets. Thoughts? thank you so much.
Use ferite filters in the DC line to keep noise off the power going to your radio.
It is all over the Web about converting those ubiquitous computer power supplies over to bench supplies, and it seems that everyone has one sitting in their basement. And it alsoseems that a lot of them have 12VDC @ 40+amps, and if you add a buck boost converter, you have a PS that gives you 5VDC for USB and up to 35VDC of adjustable, plus a fixed 12VDC for your radios. And it is not expensive nor hard to do.

Greetings from the UK! 🇬🇧🤝🏻🇺🇲
Thank you for your electrifying wisdom...
I wish I'd known all your tips and tricks before realising I couldn't just plug my IC-705 directly into a wall socket... 😱🤣
But thanks to the lovely gentleman at Waters & Stanton in Portsmouth, England, I'm now using a very small Pro Audio KX-33 adaptor (230V => 14V) designed for an Elecraft KX3. Works a treat, job done!!!
Stay safe, best regards,

Good that you pointed out HF radios need about 21A to put out 100W. I bought a 12v LiFePO4 battery for portable work. I transmitted with 50w or less, and the battery lasted a very long time, longer after I attached a solar panel and charge controller. I now have a kind of semi-permanent shack (literally, a shack in an olive grove) and power my devices 100% with batteries and PV. I would like to be able to transmit with a full 100w, but the LiFePO4 battery says, " no can do." That has to do with the battery chemistry and construction. So now I have go buy a more suitable battery that will deliver constant 20-25A, which means in general a bigger, more expensive battery. My XYL is not amused. So keep the constant output current in mind when you buy a battery. If you want 100w RF output, you will be dissatified with a battery like mine. 73!
Hello Tim, my batteries from "Eremit" create 100 W on the TRX. With 18 Ah, 50 Ah and more. With built-in BMS. Arthur von Funkwelle's UA-cam channel is also testing this on the FTDX 101. That works with it, 73 Jürgen DK4BU
Eremit LiFePO4
The Icom IC-7851, Kenwood TS990S, & Yaesu FTdx-101MP have the power supplies built in.
No, the ftdx101mp requires an external psu.
@@Dreamlgider ah, I don't have one in front of me, but it probably works like the FT-2000D it is external, but it ships with the required power supply. The yaesu specs say it requires mains AC voltage.
@@josephdurnal yup, the 101mp is 200w and comes with a dedicated speaker/psu. the ftdx101d is 100w is "12v" (13.8v) 73 de oy1r
Best noise free power supply, 200 amp hours of battery that is not charging while you're using your radio. Good luck hauling that around with you.
Oh Great Ham One! We thank you for your insight into the power! Just seems the auto focus keeps getting you though... But how crisp and beautiful the image is!
I had a “product showcase” feature on just testing it out. I’m too animated with my hands for it I think.
Autofocus seems to work well outdoors but I’ve given up on using it indoors.
@@n2rj Its that "product focus" feature on the zv-e10. Wanted to try it :D
@@HamRadioCrashCourse yes that’s the product showcase feature. In general it relies upon autofocus which doesn’t work well indoors here so I turned it off. It’s not a bad concept but I think it needs improvement. I just set manual focus now.
I've been a ham for quite a while and I wish this info was available when I first started. My reasoning for learning these comm options was SHTF. Now my question to you is, when SHTF is there a counter measure to help prevent or protect against government jamming frequencies? I see it being, NO. There is nothing we can do. And pray this never happens. But we never know when this may be the case.
Be frequency agile. Hop bands as needed.
How do I regulate/control the battery output to the radio to have a constant Voltage? I see small variations in my Voltage while operating with batteries and I don't like it, not sure if it can cause problems in a long term. Tks for the video!
Most newer radios are fairly tolerant of battery dips. They make devices that supply a consistent voltage, look into devi
Great video Josh. PS luv the shirt 👍
Is it safe to have a handy talkie near air bags??? Read it wasn’t so wanted more thoughts on it… Appreciate any understanding on it…
Likely not a good idea in front of airbags. Like between humans and the airbags. 😳
@@HamRadioCrashCourse ok appreciate that… Wife curious, y’all know us men got to ask, lol
One of the best upgrades I did for my car battery. Get a automotive AGM battery, I got mine from autozone there Platinum series. Thy take deap discharge better and the on time is longer when the motor is off. The voltage sag is less when starting the motor. The one in my van is going on 7 years and still strong. Just replaced the battery in my other vehicle the one.
Any link for the PowerFilm Solar panel...couldn't find it in your list! 73
Try Gigaparts. They sell them.
Where's the link?
Good video Josh👍❗️ 73. KV5P
Thank you!!
HIIII I M NEW BEE IN HAM , I HAVE A QUESTION , IN POWER GRID FAILURE , CAN I USE MY HOME INVERTER SQAURE WAVE BATTERY BACKUP TO POWER LINEAR POWER SUPLY (30 AMP 13.8 V ) WHICH GIVING POWER TO IC7300
Yes.
the baofeng i have charges with usb, so i can use a battery bank, solar or even a dynamo i bought
Sure. But likely not while also running the radio. Etc.
@@HamRadioCrashCourse indeed but that's what it's internal battery is for ;)
I am looking for such a cheap, readily available and flexible solution. I like that it uses standard components (there will be plenty empty powerbanks available in a grid down situation). Charge them with your solar panel (portable or from the grid connected panels with a emergency off grid solar inverter) and you can hand out full powerbanks and power a lot of radio's.
What is a QRP radio?
There are so many precautions to take and think about when it comes to connecting your mobile radio directly to your car battery. So to avoid that I was just thinking........why not just purchase a separate stand-alone battery? With a stand-alone battery you don't have to worry about the radio effecting other components to the car because the separate stand-alone battery will only be dedicated to the mobile radio. It would cost me almost nothing to build my own compartment in the trunk of my car for a stand-alone battery. What do you think of that?
For remote work, I like Bioenno and Jackery.
Me too!
How is a 12v battery increasing your power with the 705 when it’s rated for 13.8v ?
The ht battery it runs on is lower voltage, so less output power. If you give it 13.8 volts, it’ll put out ten watts.
I run my equipment off of the energy produced by my 15 month old. Tough to convert and sometimes has spotty output. 2/10 would not recommend.
Wow, thank you for the nice gut chuckle, I needed that!
Most of the energy produced by 15 month olds is wasted coming out the top and bottom.
In the movie the matrix they have it all figured out, maybe watch that for inspiration.
@HamRadioCrashCourse, @Josh... Being a noob to Ham radio I caught wind of something the other day that I was hoping you could clear up for myself and others who may hear the same thing at some point...... Can a person use a CB 'Linear Amp' for Ham radio?..... I have tried to look this question up here on the web, but I'm just not having any luck. Personally I kind of feel the person who told me was being a douchebag and hoping I would fry something so they could be entertained at my expense. I am currently studying to get my license and hope to take my test soon. Thanks my friend, love your content!! Keep up the good work and hope to hear back from you!
You might be able to use a CB amp in 12 or the 10 meter band. You might need to adjust the amp.
Im intending of getting the Anytone UHF/ VHF radio. It says it is DC12V- DC13.8V. What does it actually mean? Can I power it with just 12V ?
Yes. It’s asking for voltage between 12-13.8. How many amps does it also call for?
@@HamRadioCrashCourse I couldnt find what is its maximum draw, but on their site they say that the recommended PSU current is 10A.
You would need a power supply or battery that can handle 10 amps at 12-13.8v
@@HamRadioCrashCourse Thanks, Josh
Yes, a while ago, I had a local two way radio
dealer, install a cable from the battery 🔋 to
the passenger compartment with the appropriate connector to match my mobile
radio, which will not perform well on below
the required voltage, such as a portable
battery 🔋. 73 de W2CH, Ray
This seem to be all quite expensive and complex gear. Do you have simple solution for simple hand held radio's. For example, solar charging a simple usb power bank, and use that at night to charge your recharge the hand held radio's? I do not plan on continuously transmitting with 100's of watts in a grid down situation, just with local living family members / friends. (Even The light saver max is already 400$)
Sure the usb dc cables I mentioned will do that. Just find the for your radio.
@@HamRadioCrashCourse I somehow missed that part - I found the right cable for my plan, thanks!
You can figure out how much your cigar lighter delivers is to simply find the fuse and check its value.
The connector is rated at 10 A max anyway. Fine for that 2M mobile.
How is that DMX-40 working out for you?
A video is coming soon!
I am a 27 year old women am i the only young women my age that is licensed and loves ham radio ham radio is basically my life i really live for this hobby
Glad you’re out there on the air!
That IC705 is pretty cute. I'm just not leaving the house due to pandemic, so can't really rationalize it.
Ohhhh, i need a power Suply or batterie for my radio? First time here about it..........
It depends on the radio. What are you running?
My goodness man! How many radios do you have? What is your electric bill every month?!
Electric bill = yes
Shame no powerfilm or bioenno product is available outside the USA
A suggestion: you sometimes say "amperage" and other times say "current" and
that can be confusing to a beginner. "current" is really the correct term.
This is a good point and I’ll try to remember the correct terms. 👍
Also, sometimes people say "wattage" instead of power.
Hello everybody, I would like to get my L1 and L2 Ham license. My intention is simple, monitor for what is stirring in the weeds and in the event of an emergency be able to transmit. I have a limited budget, so I don't qualify for an enthusiast or hobbyist. What ham at home radio can I buy, so I can use the L1 and L2 online courses to get my license?
-Regards,

Which country are you in? I am not familiar with L1 & L2 here in the states.
@@HamRadioCrashCourse Bastrop TX USA :) HamRadioPrep is how they label the Technician and Technician + General license classes. Do you know of HamRadioPrep?
@@HamRadioCrashCourse I currently own a very entry level ham (BAOFENG GT-5R Dual Band Two Way Radio 144-148/420-450MHz) will this be enough to take the classes and pass the exams?
If you are running power from your mobile battery and place a properly sized fuse in line at the battery connection you will never have a burned wire, because, a fuse is there to protect the wire, not your appliance...... radio or equipment!
Instead of making these radios where a power supply is needed, why doesnt ICOM, Yaesu and Kenwood make their radios with regular plugs that can be plugged up into a regular wall socket in the home? How hard can it be to make a radio that plugs up into a wall?
You want them to include a ac/dc power transformer in the radio body to make it heavier and more expensive? What about the people that only have 12 volt dc in their shack or off grid setup?
@@HamRadioCrashCourse Paying a little extra for shipping would not be more expensive than going out and buying a power supply. No where near as expensive as getting a power supply. Even the cheapest power supply for your average ham radio is about 4100.00. There is not way that shipping would be $100.00 more if they included an AC/DC power transformer in the radio. No way.
@@HamRadioCrashCourse As far as off the grid setup, they can still make the make radios that have the all all connections in one radio including a plug.
Companies don’t want to make two radio models one with a different case and power supply and one without. It’s not worth the effort and costs.
Further, power supplies usually power more than a radio in the shack. So that’s an issue.
If the supply fails, a cheap part, do you ship the whole radio back?
FYI, this was tried in the ham radio market. The customer base didn’t want it.
👍👍👍
Fuses do not protect the radio at all.. What they do protect is the cable itself. The fuse burns out before the cable catches fire.
… which protects the radio too?
I use old socks... the stinkier the better! I used to use my old lady's worn knickers, but the voltage was too high. Nasty!
such a hassle to find the power supply from your link, you should have a direct link to item.your loosing out money, jut easier to input name of item on amazon,.just saying
I thought for sure this was going to be a jackery ad, it seems they send portable power units to every UA-camr these days.
They might do that. But I bought mine and the panel. 😬💸
I **REALLYYYYY** wish someone would make an HT that would charge directly off of USB-A/C... cmon... Everything is made that way. I've used some USB-A to DC adapters but they are all noisy. I want a damn USB jack directly on the radio.
Radioddity GS-5B has a charging port on the back of the battery that connects to USB.
Yes there are batteries like this, but they don’t recommended charging it while the radio is running.
@@HamRadioCrashCourse Good point, but that's what you get when you charge a 7.4v battery over a 5v USB port.
Solution: have multiple batteries. Continue operating while charging off USB.
Or do what the rest of us do and get an HT with a 12v charger. I was just pointing out that USB charging exists for an HT.
Meh, you don’t buy a refrigerator that needs a power supply, ham radio companies are just cheating out
Not really. It’s all 12 volt systems.
for some reason that is apparently beyond me, those Bioenno bastards charge far more than they need to for their gosh-darn batteries compared to almost any other brand that I've researched............. Apart from overflowing greed, what the HELL is going on with those folks from Bioenno?
Different cells, different BMS, etc.
