Did the calculations for this in January finally building it. 1340Khz. 1/8 inch tubing would be close to the ideal conductor but winding it with what I got right now. I think its 20awg

Nice work

So i guess there is someone else out there who is doing this.. I was beginning to think I was the only person working on this

Best part is the way my neighbors look at this 5ft tall 4 ft diameter coil in my back yard. Some think its a chicken coop, some think its a fort for my kids, and I'm sure there are a few who think its some sort of ufo landing pad lol ... So far I have only met one person (in person, not on the net) who actually appreciates what this is actually designed for, and kinda understands what I'm talking about when I try to explain it, and he is an old military guy.

Hope u keep posting updates here. Will be nice to have someone to bounce ideas off of who is building one too.

CRI Update

Did some calculating for my capacitor and have built a fairly crude looking but hopefully effective capacitor.IMG_0705.jpgIMG_0706.jpgIMG_0707.jpgIMG_0708.jpg The size of plates and how many is based on surface area of the secondary coil windings surface area. I calculated the surface area of the entire coil and adjusted my primary as well IMG_0709.jpgIMG_0710.jpg so that the surface area of all 3 components is within 100sq/in of eachother. This hopefully will cause the coil to resonate better. Also I have got the material now for the extra coil so I will be starting work on it next. This coil will be 1'6" tall and wide, it is a 1:1 ratio coil. Coil will be 90 turns with a wire length of 439'4" and close to 10awg so that is what i am going to use. Also I am changing my topload, The copper hemisphere I have built could possibly cause what looks like a dead short in the coil so i will be replacing it with 2 Toroids made from 6" aluminum foil ducting which will be capped with an insulator on each end to prevent this dead short in the coil.The big toroid will be around 3 ft in diameter and the smaller will be around 2 ft.

CRI coil for 1340Khz Kvot

Corrected 1/4 wavelength= 142.25 ft.
using .7752 correction factor. 102% velocity factor X 76% burden factor.
I avoided all rounding till the end
Length per turn= 85.35 inches
At this point I figured for an octagon instead of a circle since my coil form is an octagon and I'm trying to be as accurate as possible so I calculated 10.67 inches per facet of octagon
Diameter of circle would be 27.18 inches
Height= 5.44 inches

The tuning seems to be right on. With topload and ground connected I can hear the radio station clearly through a regular crystal detector consisting of a germanium diode, demodulation capacitor, load resistor and crystal earpiece. It makes noise but unintelligable with no ground or top load.
At the moment the detector is connected across the secondary. I put together a simple amplifier using a LM386 IC driving a piezo element.
With the amplifier 1340Khz comes in clear with the secondary connected to nothing. When I add the top load the signal gets a little bit stronger and when I connect the ground the signal gets a lot stronger. I have tuned it up to 1510Khz by tapping the top load at the 16th or 17th turn. And I have accidentally tuned it down to 950Khz by adding a long ground wire one day when I didn't want to carry it out to the ground rod.
That's what I have done for testing so far. Oh and I did put a temporary primary on it with variable capacitor. There is a sweet spot where it raises the power of the secondary. Getting ready to rewind the whole thing. I am happy with the frame. More appropriate wire for the secondary and some 4 inch wide copper flashing for the primary coming soon.

Great Looking coil Leebob.

Also, there is about a thousand foot deep rift in the earth between here and town "Rio Grande Gorge" I wonder what that does to the ground signal. I'm gonna have to take it to the other side of the Gorge and do testing there also

CRI Update

Woo Hoo I won the CRI

Just want to throw out a special thanks to Aaron and Eric for the "Crystal Radio Initiative". It has been a time consuming build but very educational for me. Also a shout out to the annonymous donor of funds for the CRI Challenge. The funds are going to good use on the build.

I have now finished the extra coilIMG_0719.jpg and have added a precision adjustor to my capacitorIMG_0717.jpg IMG_0718.jpg Lol. Crude but effective. This is the beast with the extra coil and new toploadIMG_0716.jpg. I have pounded my holes in the grounding and am just waiting to receive funds for the aluminum to fill themIMG_0720.jpg. I have also decided that instead of using the 4awg copper, i am going to dig a thin trench about 12" deep and pour aluminum between all holes. I will also be pouring an extra eight holes in addition to these in the same pattern only 10 feet out. Also connected the same way. I am hoping i can get about 200lbs+ of aluminum in the ground. This should be effective as a good grounding system for now.

CKLW is a 50,000 watt, Class B, AM radio station . Is this the station your trying to pick up and have you done any receiving yet LeeBob. The local station I built for only puts out a thousand watts. I think maybe I could do pretty good by taking it to town and connecting to a fire hydrant for ground.

ground here is dry sandy clay. I pounded a 4ft piece of rebar for a ground to start with. Then I tried my roof. I am building a concrete dome on top of rammed earth walls. There is a 3ft piece of rebar every 30 inches driven into the rammed earth walls to connect the bond beam to the metal skeleton of the roof. The CRI coil and the crystal radio both work better using this for ground than a standard ground rod. I have not made an actual ground plane yet but I do have the room to do so. the rammed earth walls are a 20ft diameter on the inside circle and the walls are about 30inches thick so the connection to earth is good as far as surface area goes

Thanks Jeff

Your coil sounds like its coming along nicely. How far are u from the station u are tuning for. And as for the rift it shouldn't effect your signal to badly as it is still connected down there somewhere. I am about 25 miles from the radio station which i am trying to recieve and have a hard time to get the station on my Iphone doc with the antenna at exactly 90 degreesIMG_0721.jpg to the station signal. The interesting thing i accidently discovered after messing around with the coil yesterday is that with it plugged into just the house ground and the extra coil and topload in the circuit i was able to lay the antenna coil from the iphone doc flat on the tableIMG_0722.jpg and the station would come in clearly. I thought at first that maybe it was just the weather at the time or something but as soon as i unplugged it from ground the station would cut out.

Just as a suggestion for when u put in your ground network, maybe run some pvc pipe beside ur ground rods and wires with holes drilled so u can flush an electrolitic solution down to the conductors to help them. I have done this before with gardens for feeding the plants. It will saturate the soil and the conductor giving u a larger conductive surface area. I was going to do this with my system but my water table here is less than 4' from the surface so it is kinda pointless here.

Looking into what to purchase to wind the secondary with and am really getting confused. I am looking for a 6 AWG size conductor. 1/8th inch copper tubing and 6 AWG welding wire cost about the same. The welding wire is made of many small conductors so should be good for skin effect. I saw some 6 AWG Litz wire on Ebay made of magnet wire but that guy didnt have a long enough length. Might look into a spool of that. A cheap solution is 1/8th inch wide copper tape. Lots of surface area low mass???. And the there is the suggested teflon insulated coax. What would i be looking for in coax that has an outer conductor the right size??? Any suggestions and or pros and cons of each choice would be much appreciated. Today I got an antenna 29 feet into the air and am messing with a standard crystal radio.


oh and I am 15.87 miles away from my thousand watt station with the rift a little closer to me as per attachment on post #38..........and yes have done the PVC pipe trick for trees out here in the desert I will do that for my ground rods when I get them.

Hey Jeff

Sounds like u have some good ideas for conductors, Only thing I would suggest is to stay away from buying anything for now. The trick I used was to scrounge at the dump and local guys with junk in their yard will sometimes sell u bits and pieces for pennies, also an option that I almost took was to use many strands of magnet wire scrounged out of a few old CRT tv's, U can get about two layers of full length turns from one tv depending on the size,I calculated that I was going to need 8 turns of magnet wire to make up the conductor diameter, so I would have needed about 4 tv's about 27" or bigger ... Now that said u may not be able to find the exact conductor diameter for your project. I found that it was easiest for me to do all the math for my frequency following Aaron and Eric's video presentation and the e-book. Then once I knew my conductor length i was able to find something of that length that I had laying around luckly, which was actually quite a bit larger then I wanted diameter wise but its what I had. So I took my conductor diameter and started to work the math backwards till I came up with a form size built for the conductor diameter. That is why my coil is so large. I looked up buying conductors of around the same diameter and it is very pricey for experimentation purposes. I found it much cheaper to buy material to build the form a different diameter. As for skin effect, I am no expert thats for sure. I have read a few papers on it but it was about three years ago now and my knowledge retention is dwindling with the more kids I have lol. I will have to look up those papers again and get back to u. Pretty sure I just googled conductor skin effect at high frequencies. And as for the coax cable. I looked into it as well but I wasn't sure about stray capacitance between the outer conductor lining and the inner wire. It may have an effect on tuning. Hope this helps

I do have enough of the pictured wire whatever it is. It has 3 twisted pairs and a copper? foil sheath. The foil sheath is a little large but the entire wire with the insulation is about right to tight wind the thing. I have also thought about using the twisted pairs inside as some makeshift litz wire. I want to wind it with copper tubing but not for any really good reason other than it would look really good with a copper flashing primary. I am kinda leaning towards using the twisted pairs at the moment. If anyone has pros and cons of each choice it would much appreciated

After trying to research alternatives, I am back to my original notion of winding the secondary with 1/8th inch copper tubing. And will be stopping at Architectural Copper for the primary on my next trip to town.
Correction...Make that 3/16"o.d. copper tubing for the secondary!

My skype call with Eric Dollard.

I asked about grounding. He basically said that the deeper you can go with the maximum amount of surface area will give best results. Also using a large piece of conductor to join all grounds on the surface directly below the coil will help in tuning. He also spoke of using trees as a source of grounding, by using a rod driven into the base of the tree allowing the root system to conduct the signal deep below. The bigger the tree usually the deeper the root system. Main thing is surface area as close to the water table as possible.FYI His grounding system is 17 acres.

I asked about skin effect. In my case with aluminum which is a ribbon style conductor making it thin, the skin effect is not an issue. The skin effect is more of a factor in large awg solid round wire conductors at high frequency. In which case is best to use brass.

I asked him about insulated wire compared to non-insulated wire. His recommendation is to have all components of the system as well insulated from air and ground as possible. Insulation on the secondary and primary windings will help with the self capacitance.

I asked him about capacitors. More small capacitors are better then one big cap. He suggested tank capacitors close to my capacitance and a smaller adjustable cap for fine tuning. Best if vac caps are used.

Other suggestions given were to not go overboard with the topload like me lol. All that is needed is a smooth conductor which should never exceed the diameter of your second coil.


Im sure im probably forgetting some stuff but I will post it as I remember.


Thanks for your help Aaron and Eric, can't wait to see this years presentation vids.

Just a quick update. Ordered 2 50' coils of 3/16inch copper tubing today...at local lumber yard. Ended up being cheaper than Ebay but it will be a couple weeks. I will need one more 50' coil to wind the secondary, it is about 145'. The Architectural Copper guy was not in today. He is also a river guide so not the best time of year to catch him at store. I had intended to get the copper for the primary today. I also put a longer and higher antenna on the standard crystal radio. It ended up being pointed right at the local radio station and nothing else would tune in. I was getting about 6 stations with it before. 3 of them were strong enough to listen with unpowered crystal earpiece. Been some storms here so antenna is down. gonna point it a different direction next time. A good ground connection is going to be tricky here. The water table could be 1000' down where I am at.

Just want to post an update on the coil. I have been very busy so progress has been slow. Although I have had the time to get my grounding system put in and I am in the process of getting all the connections together for some testing. I have 9holes approx. 3-5ft deep and they are in a star formation with one at the centre. They are spaced about 8ft from the centre and about 6ft from each other. They are all connected like a spider web with 4awg copper. There is also 4 50ft strands of 14awg aluminum welding wire running straight out from each hole buried about 12inch underground. Here are the vids of me pouring some. https://youtu.be/qjVALjfi94E, https://youtu.be/cg4l0VWKoIQ, https://youtu.be/MrU7fDjoAxM

CRI Coil Update

So I connected everything up for testing and have run a few tests on the coil with my frequency generator. My initial tests were not what i was hoping to see as the secondary was resonating closer to 600khz rather than the 800khz I am shooting for. So I went back to my books to look over my initial calculations for the coil to see if i was mistaken, and I have found that somehow I messed up on my calculation for coil diameter. It was calculated originally to be 18 turns at 4'10" to be 247' winding. But when you do the math on that 4.84*3.14=15.2*18=273.6. So this means that I am going to have to reduce the diameter of my coil to 4' 4 1/2" to bring my coil to the desired 247'. 4.375*3.14=13.74*18=247.32. Time to start unwrapping and rebuilding.

Don't you just love those stupid rookie mistakes I really annoyed myself last week when I measured 44.1cm for a shelf type arrangement, wrote it down on a piece of paper to avoid errors, then went and cut out a piece of wood, installed it, and found there was a big gap. Measured what I had cut - 41.1cm. But luckily I needed a hole to pass things down from above to below the shelf anyway so the gap got incorporated into the design. Typical case of more haste less speed.

Thanks for the updates, I hope the rest is going well!
