No batteries, no problem. The joy of listening to AM broadcasts without any power source has always been fascinating by many including myself.
When I was younger the Science Fair Crystal radio set was my introduction to AM and its wonders. Fast forward to 2008 and my interest peaked again in the hobby and had me interested in building my own kit or buying one already made.
The choice was easy once I found out about this little wonder. The Howes CR-5 was perfect, and it was very inexpensive for all the labor and materials that went into handcrafting it.
The choice is simple, get one of these sets before they are gone forever. This person builds them with so much care and attention to detail that he must be doing it to help promote the hobby more then making money for himself.

3:07 That is so cool looking! Problem might be all of that metal in close proximity to the tuning coil could lower the Q of its inductance, thus causing the set to tune more broadly
yes getting sound from the airwaves for no energy input always fascinated me.. you should also try to light up LEDs with it!
I totally love this radio and this video, well detailed in a very understandable way. But please excuse my ignorance, I have to refer back to other videos or schematics to see where to hook up the earphone.
It is a very good looking radio. I would try an antenna coupler (another coil magnetically coupled) to see if that could improve it any. I used to have one of those "Science Fair" models back in the early '60's, it only got one good station and usually another weakly. This one looks like it is based on it with improvements.
Thanks for sharing bro! I've made this one too! It works!!!🌞🌍👍
Very cool!
I bought several off of eBay some of them were very old and a couple were made by the guy that uses antique radio parts I got one that is really beautiful brass fittings and everything
hi todd can i also use loop antenna with that?
Would you please show us the diagram for this radio?ty
Link to eBay no longer works. Discontinued?
It is a good design. The wiper that moves along the coil is enough for tuning alone. Otherwise the variable capacitor will do the same thing with no wiper. This design has both to give two ways to fine tine.
I bought one coil that's 40 m short wave and Marine band with two antennas that one is cool
coil plus cap makes a resonate freq tank circuit less coil more cap makes a sharper tuned circuit if there was a second smaller coil for the antenna coupled to the tuning coil it would be even more selective
Neat!♡ 👍
where is deomstration ?
Hello,
Is there any chance to see/hear how it works and perform?
In the future I may revisit this set. I need to live somewhere else so I can put up a decent long wire outside and a solid ground connection.
Hallo Sir, are you sell this radio? Greeting from Indonesia
Is this TESLAS Crystal Radio That he Talked to the Dead with ? Has anyone figured what band Its picking up when people say it's the Dead ? Would be interesting to get into
Here is a similar build, it seems you bring the output into a computer for modulation... smoke and mirrors here :) a kit I found, www.mikeselectronicparts.com/product/spooky-tesla-spirit-radio-parts-kit/
Sir can you please tell me about antenna could,i.e. what gauge wire is used ( SWG/AWG), NO OF TURNS, DIAMETER OF PIPE ON WHICH COIL IS WOUND.THANKING YOU IN ADVANCE
25 turn primary (antenna coil) on a section of aprox 3 inch diameter pvc pipe....120 turn secondary (start winding right behind first coil)....another 25 turns in center of secondary. Wrap a strip of paper over secondary before winding third coil. Use 24 AWG magnet wire. Connect 365pf air variable capacitor across 120 turn coil. Connect germanium diode and high impedance crystal earphone/headphones to 25 turn coil wrapped over the 120 turn coil. Telephone speakers work well too. Connect antenna/ground to first 25 turn coil.
Antenna can be any type of small insulated wire at least 100 feet long as high off the ground as you can get it. 250 feet long is even better. A fishing rod can be used to get antenna wire up in a tree. Tie a lead weight to fishing line and throw it over the tree top. Tie fishing line to antenna wire and pull it up then tie fishing line to base of tree. Or you can string out the antenna wire between trees....just get it high enough that nobody will walk into it and rip it down.
You can use a counter poise antenna as a ground....just attach another length of insulated wire to primary coil instead of a ground wire and string it out through the bushes or trees in the opposite direction. Get it up high enough that nobody gets tangled in it.
This is a very sensitive and selective crystal set.
PS: PVC pipe diameter isn`t critical. You can use 2 3/4 inch pipe or 3 1/2 inch pipe with almost same results and tuning range....520khz to about 1600khz. You can buy 500 ft spools of cheap insulated wire off Amazon.
TIP: Use super glue to hold windings in place as you wind coils. This way you can rest some and not have to do it all at once. Hot glue works well too. Be creative.
@@chimpjones6219 Your instructions are clear and concise. Thanks so much and I hope to report back soon with my own build. Also, what would you have to do to get reception up into the shortwave bands?
@@jdschauss I used to make a crystal set that would receive WWCR 5065 by winding 4 turns of 26 AWG wire on a paper towel tube. Then right behind that coil wrap 14 turns. The tuning capacitor, diode and earphone are all connected to the 14 turn coil. The air variable tuning capacitor I used was around 200 pf. Connect a 170k resistor across earphone leads and volume and tone will increase. This design isn`t very selective. It`s designed for the most volume at night to hear WWCR. The coil turns need to be spaced apart more for selectivity. Just experiment.
@@jdschauss Just throw ends of antenna wires out the window when not in use and during storms or lightning will come inside your house.
@@chimpjones6219 i may just install a BNC female chassis mount socket and use an 80 meter dipole. Should work, unless a crystal set just absolutely MUST use a real earth ground. Barring any requirement for a Marconi styled antenna, I can make an 80 meter dipole with about 132 feet of 30 AWG stealth wire that folds up nice and small for travel.
Sadly, he's no longer on ebay
Any way to contact this fellow, and purchase one of these directly?
@System 3: I bought a brand new fully assembled unit from him about 3 months ago on eBay for about $58.00 which included shipping. I think it’s a wonderful little set. Good luck. 👍
1:45 Very impressive quality
hi,I want to buy this radio,I am Turkey
Seria bom uma tradução ou legendas com esquema e dados da bobina.
Who buys a crystal set? It takes the fun out of it. The thing is to build your own.
The person who has built their own, and wants to see how someone else's work performs. In this case, I was happy that this gentleman's work was top shelf for the cost. I also want to venture into collecting original sets built in the teens and twenties.
You might want to buy an outstandingly built CR radio as a benchmark in performance in order for you to make an acceptable radio that you can enjoy. Don’t waste your time building foxhole radios - they’re so frustrating.
Yes, winding/constructing your own coil is the best part
Good point.
wonder what the coil would be like with 12 guage house wire
It would be awkward to wind but OK in general.
have you tried that? you might get voltage and amps from them..
The seller is not exist :( .. can you help to find him
My link in the description above still works, he has four in stock.
Thank for the quick response. Can you post the link here please :)
For some reason I can't paste a link here. Search " Howes CR-5 Cristal Radio Set" on ebay.
Found him and bought one. Thanks for your help
Where's the band scan?
I'm still working on a long wire setup to get decent reception.
shoot it appears that it is no longer available :(
The guy made a few hundred of them, It is a bummer he no longer makes these.
Looks like about 500 pF tuning capacitor.
😮😮😮😮😮
Mine is S# 171 (10-4-14)
Nice!
Esperamos escuchar como suena.
NEAT RADIO IT HAS MY LAST NAME HOW COOL IS THAT MY LAST NAME IS HOWE
Very cool, maybe your relatives :)
todderbert could be thanks 🙏 for the reply my friend
Howes was a British radio kit maker years ago. RX, Tx, and Vfo 👍

Only ONE station ?????
I built mine way back in the 1960's. In the wilds of Oregon. And with a 50 foot wire anrenna I got 4 very clear stations. With my 100 foot wire antenna, from 12 to 18 stations !!!!
Me thinks you were either living on MARS or, maybe you put it together wrong??? 😢
I'm not able to have an ideal outdoor long wire for it. The radio will perform.
