Hi,

I have some questions to the T-R-Locator.

1) Is the schematic drawn correct? Because the TX coil is in series with the tuning capasitor but the RX coil tuning capacitor is in parallel connected to the coil. From my feeling the TX tuning capacitor should be also in parrallel to the coil like the RX tuning capacitor.
2) For what actually is the tuning of the coils for?
3) How and what is to be tuned?

Thanks in advance

1. TX tuning capacitor should be in position as on the circuit. by the cap, by its value, you can change a current in the TX coil.
this in not current resonance you sure need to get, but just for the control of current, ie TX power in ground.

Hello kt315,

thank you for your reply. I think this helps me to understand the circuit better.

Hi guys

old thread, but maybe someone can share their experience with building and using two-box?
I have built Delta Pulse and it's good, but 1x1m loop is not handy in a forest and bushy areas.
Looking at simple two-box designs that are handier, but there are very polar opinions on the internets.

[bernte_one]

just build it, it works you can do with two coil of 30 or 40cm each, this is handy enough for the forest and also good depth penetration in ground

sevzirfo is seeking at x-Finland land. you perhaps know that part of Finland territory was been taken by Stalin and now it is under Russia.
Vyborg is former Finland city.

You are lying. Finland was part of the Russian Empire from 1809 to 1917. Then V.I. Lenin gave her independence. You don't have to be heartbroken

[GeoMax]

Actually this comment does not belong here....

Everybody should be aware of the Political Russia. Russia do what they do since many centuries.... occupaying and stealing other peoples land. You can see it currently in Georgia and in the Ukraine until today.

No politics, please. Arch, KT is correct, look up the "Winter War" and you will see that Finland had to cede Karelia and other territory to the Soviets in 1940.

[ArchibaldSTM]

No politics, please. Arch

You should address this claim not to me, but to KT. I just made a clarification of the facts.

Unfortunately, editing Wikipedia can be accessed by anyone today.
I'm not privy to this particular case, I don't know the facts, but I do know that Wikipedia is the last source I would turn to in search of the truth.
I say this from personal experience. Due to some erroneous reports on Wikipedia: I and my people have been suffering severe consequences for decades.
Of course, Wikipedia is not that old, before that there were some other malicious media, which Wikipedia inherited and consolidated.
The one who learns from Wikipedia and bases his knowledge on information from Wikipedia; is deplorable.
Carl you finished school and I guess university. And that's how you became an engineer. After that, you worked in various companies in the field.
And through that work you gained additional knowledge and experience.
How would you feel if you met someone who was mostly "educated" from Wikipedia and similar sources, on the subject of your occupation;
and that he starts talking to you about things that you know very well?
I believe you personally would be very disgusted by such person and such behavior.
Wikipedia is an entertaining almanac with 90% flat one-sidedly interpreted ideas and thoughts and only maybe 10% of some truth.
As for politics; I am an ardent debater when it comes to politics.
But I was repeatedly warned and even banned from the forum for exaggerating and disrespecting the forum about this.
And since then I have decided to respect the rules of the forum and that this will not happen to me in the future.
Despite everything, I don't have a bad opinion about the KT315.
He has been on the forum for a long time, he has contributed a lot to the forum and I respect that.
As well as the fact that he has been there as a member for a very long time. So a kind of habit is created.
But the first time I was warned very harshly and then banned from the forum precisely because of an argument with KT315.
That was when the Maidan happened and when KT315 took one side without a critical review and a deeper understanding of the problem.
Today, here it is almost 9 years later; let's see where that got us.
The point is; a person must have an inner urge to critically perceive the world around him.
And in order to be successful in that; one must first get rid of the ego and be fanatically honest, first with oneself and then with others.
I will not elaborate further on these topics because they are sensitive and we all know where this leads.
But I will notice that KT315 still occasionally inserts a similar remark in one of his posts. Of a political nature.
The statement "you perhaps know that part of Finland territory was taken by Stalin and now it is under Russia.Vyborg is former Finland city."
has nothing to do with the topic of the forum and should not be there.
Because it is primarily a political statement based on incorrect personal views.
Folks, we live in very unusual times. The world is irrevocably changing into something new... which seems very scary to me.
Let's preserve this forum as one of the last oases where all people are still welcome.
Without politics and political opinions and ideas.
And let's get rid of Wikipedia and similar media. We don't need that "knowledge" here.
We have much better literature available.

I will give myself just a little more freedom to present here a universal and highly illustrative case.
So if the admin decides to delete this post; let him, I don't mind.
We remember the day someone from the State Department got on the podium and announced that they had finally found irrefutable evidence that
Iraq had weapons of mass destruction.
We remember how the public reacted then. Not only the US public, but also a good part of the world public.
And we remember how it developed, what it turned into and what happened in the end.
Today, many years later, we have just the necessary time distance and more than enough accurate evidence of those events.
And what do we do now?
How will we compensate for all the damages and all the victims of those lies?
Did someone say "we're sorry, this won't happen again and the culprits will be severely punished!" ???
No, the "great power" does not apologize to anyone and does not compensate anyone for damages.
I'm not saying this because I'm just some passionate "political scientist" without 2 minutes of schooling in politics.
I say this because I am one of the many direct victims of similar events in the past.
Similar and worse lies led to my suffering and the ruin of my beautiful homeland. To this day, those torments and agony continue.
And it didn't stop there!
A part of my beautiful homeland was forcibly taken away for the benefit of some.
And today I notice that Wikipedia history is being edited and written by some from the ranks of those for whom my beautiful homeland was
destroyed and torn apart.
I even saw a couple of articles on Wikipedia, written by a half-literate and not very intelligent celebrity starlet from a nation that stole
a part of my homeland, hiding behind the power of the USA and its weapons.
Yes, you read that right; an illiterate and unintelligent starlet (in the dirtiest sense of the term) writes and edits "historical" and political articles about my homeland, on Wikipedia.
And when someone, across the pond, reads those articles, and is not even better acquainted with the real truth; he will of course be very misinformed.
And consequently make very wrong decisions.
That is the point of my writing here.
Forget Wikipedia. Forget the mainstream media. Because they are owned by individuals, capitalists, who are part of a larger group, which serves an even stronger
group of people "from the shadows", the so-called "deep state". And those media only serve their narrow interests.
Carl, you of all people should be the last person to read what is written on Wikipedia and refer to it.

...Folks, we live in very unusual times. The world is irrevocably changing into something new... which seems very scary to me...

Unfortunately, not long after this sentence of mine, a terrible tragedy happened in my country yesterday.
It's hard to be smart in situations like this. It's hard to say anything.
But these times we live in now are terrifying. And it manifests itself in various ways.
My brain isn't capable of understanding things like this...
The only thing I can do is appeal for peace, reconciliation, love, respect for the people around us.
And a big threshold of tolerance.
