Wow! How many posts here, in one day??? I need some time to read all and than to reply here...
But only short note for Nelson!
Nelson, as old radioamateur, i remeber (although misty) that you can not use those calculations for large coils...It is not same thing.
Formulas are valid only up to some diammeter (dont remeber which).
Oh, yes, you can input any value in calculations but you will get impossible results, not accurate at all. Check with some radio amateur at your place...
Most of formulas and calculations available on .net are for coil,chokes,inductances mostly used in radio designs, in most cases small sized coils...
There must be some abbreviation factor included when calculating unusuall coils with unusuall sizes.
So far as i know THERE IS NOT NEITHER ONE PROPER FORMULA for MD coil calculations....Strange but true!
Thats why all think that there is some "secret" about coils for MD. There is not....
Best way to know coil inductance is to wound it and than measure with accurate inductance meter....later to do some corrections...
I am telling this cose i also tried so many times with various formulas and neither one gave valid results.
I even reassembled one original White's coil, counted windings and compare all collected data with results got from several formulas - neither one justified experience with original coil???
Know what i mean?
Another thing;
I am big donkey!!! Sorry,sorry,sorry !!! Sorry to all members here!
Outer diammeter is 28cm! Inner diammeter is 26.8cm !!!!!!
I just realized that!? In all hurry and hush to post here some concrete stuff i measured diammeter without thinking....I could swear on 28cm!!!!
Just few moments ago, reading your complains i decided to measure all again.....!!!
Sorry,sorry,sorry !!!! It was not intended! Sorry!
I think that this could be the problem!I have used 28cm for inner diameter and 115 turns of 0,30 wire for both windings!
When I mesure the resistance its 18,8 and 18,9!
I have tryed to null with 1k resistor and 15n capacitator,but my multimeter show 0.00 why?
I have put multimeter in 200 m DCA range?Is this right?Or it should be in 200 ACV?
thanks
I use isopropilic alcohol. Look the Wilson's VLF 710 PCB after cleaning. Ready for to copy.
Isopropilic is not corrosive as other alcohols.

As you can see, I'm living in the "reality" you want. You uniform your thought because the administrator thinks in the same way. You have not own criteria. I don't need the sympathy of the admin, not yours, anybody. And I don't feel shane when I said that electronic LRL locators are a reality, I'm not speaking about brands. If you want attack brands, attack. Is not the same attack brands that attack possible (REAL) systems.
(And Max, I don't sell any LRL detectors. Also, I'm not the person who detect a gold medal at 700-800 m with electronic LRL. I was a witness! ).
Hi,
Max nice work!
I have a question.Will you tell me how much turns I need to make good coil with 0,20 mm only one I have and 22 cm diameter?DD coil!
Thanks

Hi,
0.20mm wire is not good to make these coils.
You need something from 0.25 to 0.30mm wire to suit specs without loosing too much performances.
I've made 0.30mm coils and worked ok, but required caps mods.
I suggest try something 0.25 (0.28 with varnish) to 0.28 (0.30 with varnish) to stay close and avoid much troubles.
Hi,
MAX.
I have have you test your TGS?
I still cant get my work as I wish!
I have coil probleme I think.Maybe I use 0,30 without varnich,but maybe my resistance is to low?18,...
Shouldnt it be from 19 to 22?
I will see how much its with shield!.
Please tell me when nulling in which mode should I put multimeter DCV;ACV;DCA?
Hi what is this detector? If its TGS why all pots are 10k?
Ultimate Haze, is the Wilson VLF 710 and yes, all pots. are of 10 K.
Hi,
the fact that you have a VLF PCB and some alcool to melt flux means nothing special to me. I use too that stuff, but thanks anyway for the hint!
Anyone could buy alcool or VLF detectors... and so ? Understanding what's inside is another film.
Reality ??? Reality is that you want present yourself here as an educated, rational mind but the truth is that you support nonsense.
Why ? What I have to think when you talk about sparks, gaps and 25meters for detection of a coin ?
It's arficious rethorics mask and enforce intended (fake) thinking and spoke with good arguments and facts.
Old game, old players.
The witness ????
So I'm right! There is a "tribe of nonsense" here !
Anyway I've nothing personal against you and your friends... find funny many things I read in the LRL section... always said that! just hate fake stuff, fake claims, fake games expecially when there is business around. So don't take it personal. It's general.

Put in AC voltage. You need more turns cause resistivity is lower than 0.25. Can't remember exact number now... but you can find in older posts.
Have few time to test at now:
for now
freq. 14.35 KHz
+V 8 volts (regulated by 780
-V -6.9 volts (just with 4024 in socket)
-V -6.2 volts (with all stuff)
Battery checker is working.
Found another mistake on schematic: tantalium cap reversed!
Big problem is that I need lot of solvents/chemicals to remove "well" any flux.
How do you remove flux ?
Best regards, Max
For what a lot of solvents/chemicals for a easy solution? Do you want explode when you light your Clint E. cigarr? Simple (now you know and the thanks is real): isopropilic.
As I see you don't know how. Maybe you use the alcohol for other purposes, but no for to clean PCBs. When you want to write here and in LRL section, please leave far the alcohol!
ALCO-COOL

Ah! But not in your PCB?
Have to find some spare time!!!
Best regards, Max
Also check your PCB.
You have much time, but use for build good coils.

My education said me that I'll be educated here and in other parts. So, do you're educated here and bad-educated in other instances? If I post in LRL section, I am no-educated, but you are, OK? Justice, where you are?

Max I'm on the way...
And so what?
PS: do you see the RED tantalium cap ?
And...??? Great!!! As I see, is the first time you use this type of cap.
* * * * * * * * *
Respond, please!
As your buddy RObert? He use various masks and you said nothing. Justice, come, please!
Do you deffend RObert? With this kind of friend (you) RObert no need enemies!
Do you scare in via to emit your opinion against administrator's decission?

Yes, and I'll dissect your inputs in LRL section in via for to demonstrates your funny non-senses.

Hi,
I'll light the cigar with caution next time!
But I've used already smoking ??? Anyway, I'll don't explode just to post on the LRL section!
And make some more laugh!
But if I explode then you could flood the forum with nonsense!
Best regards,
Max
BTW I know it from 25 years ago... used to clean-up tape-heads... of my C64 recorder! But don't ask me to explain you what's a C64!

Hi,
You maybe don't know what is it a tantalium cap.... you know crappy LRL ! And some alcool (so what are solvents made of ??? you are not so smart, I see!)
"Found another mistake on schematic: tantalium cap reversed!

Look at your LRL inside... cut some other PVC pipe, c'mon !
You are the master of crappy homemade stuff!
"Respond, please!

Do you deffend RObert? With this kind of friend (you) RObert no need enemies!"
Justice ??? You ask for it ??? Be carefull, justice could come there... and your door bell rings at night!
I defend Robert ? Robert has no need of my defence... I think. He has his own methods of fighting LRL-fakes... I've mine! And lot of fun
Enemies ? Your crappy things are the only enemies for us... entusiast THs !
"Do you scare in via to emit your opinion against administrator's decission?"
I'm not against administrator opinion ! It's the same... but not cause I'm scared of something (why I have to ???) like you said... but just cause for me all these CRAPPY-LRL are JUNK... no science, no facts, no proofs.
" ... find funny many things I read in the LRL section

Yes, take care at all those BS he said... YOU ARE MASTER OF NONSENSE HERE (with your LRL-tribe).

Max
