Serbian "Most Wanted"

[ivconic]

I disagree with the name of this contraption. "Caesar" or even "Cezar" is much more poetic than the initials SMW! Come'on surely there is something better!

Edit - What specifically do the "phase" and "amplitude" controls accomplish here? Also, what is U6b the opamp floating at the bottom connected to nothing doing (is that the ground reference for the other opamps?).

I can not use name somebody else invented. It is strange , especially at this particular design. There are few "designers" who are trying to take all the credits for this design. One of those named it "Caesar". There is much antagonism among those few "designers" here in local. Provincialism, vanity....what can i tell? Most funny is fact that this "Frankenstein" actually is not original design at all. It is just crossbreed between White's Classic and Fisher 1225. Even than...this schematic originally came, long time ago, from Bulgaria - not from Serbia. I received original schematic 6 years ago from one bulgarian friend. At the time i didn't payed any attention on it.

So...leaded by that logic and that bad experiences with local "designers", i simply refuse to call it "Caesar".
Not only that, also i refuse to use "original" setup because of few major lacks it is having. "Original" "Caesar" or whatever, is made very poor and bad. Not working enough good. Handmade coils i have seen so far are very bad.
So for all those reasons i decided to use only schematic as starting platform to improve and change and finally get something different and better.
So...as long as i am concerned name "Caesar" is out of question.

"Phase" is...phase! Ahahah! Simply as that. With that trimmer you can additionaly fix the phase at phase detectors.

"Amplitude" is actally preset with which you can affect amplitude of TX signal.
With that trimmer you can regulate voltage that fed into TX transistor BC327.
In original Classic oscillator there is fixed resitor; at some 100ohms and at some versions 51 ohms...etc...etc..
Replacing that resistor with 200 ohms trimmer you can fine readjust that voltage to shape up the sinus at TX output.
Clear?

"...Also, what is U6b the opamp floating at the bottom connected to nothing doing (is that the ground reference for the other opamps?)..."

ATTABOY! Indeed.

Hello Friends,

Thanks Ivica and others for this nice project !

In the Fisher 1235 there is a TR freq. adjustment, can this be used for adapting coils to make them work on that coils freq ?

Regards.

Sorry i made mistake mentioning 1235. RX part is from 1225. Although...there are simillarities between those two models.
But yes, you are right, it also can be applied as pretty useful option, too.
Regards!

How is this rapidly changing opinion? , The worst yesterday, today
the best detector, and now the work of someone else earning nice.
This detector has its original spool, great work,
no need for replacement and adjustment.

No need you to come here and act smart.

"...the work of someone else earning nice..."

By any chance; could be that "someone else" you?!
It is shamefull what you are trying to do here. Nothing constructive, just to provoke and bash.
That "someone else" who initially designed this (previous one, from first page) schematic is (by some strange coincidence) my very good friend form east Bulgaria.
So do not act smart here because you look very STUPID, instead.


I am descent enough to come out here in public and admit my own mistakes. I did that many times here and i will do that in future too. Besides i don't think that i was wrong than when put remarks, at first page. Originally "Caesar" i seen the first time was very bad made like some illiterate ignorant made it. It simply need improvements and modds.
It is much better for you not to show here any more. You look enough bad already. Bad and very stupid. And total ignorant also. Otherwise you will show some of your works and suggestions.
Your ignorancy is unbeliveable!! Every possible detector on this planet CAN BE DONE BETTER and CAN BE IMPROVED.
Shut up and disappear! Better for you!
Or start new thread on this forum with your works,schematics,pcbs...whatever. Do not spoil this thread. Start your own thread and post your "knowledge" there. I would like to see any of your works! No chance! You are from those kind of worse people - waste whole life on empty talks, provocations, bashing and harassing . To work...nooo. Work - zero! You making your fortune on somebody else misery.

I think that will be better-sound,power,tresh...

Interesting enough! Maybe i will try it soon.
Thanks!
Looks like Magnum part to me?
Regards!

[ivconic]

Glad to hear so.
One major progress.
You have found supplier for those coils?What is the price?
Can you see the changes I made around disc. pot?Is this correct?Also what are those spots in blue for?Some switch?
Thanks
I will try to find same coil on ebay.

Oh ...that is just part of 1265/66 audio stage i excluded from schematic... Never mind. Don't pay attention on it.

Hi,
Ok.So I just skip those?
Can you see the green lines that I changed around disc pot?
I think that they should conected this way.According schematic.Because I saw this mistake yesterday when tracing pcb.
Or I am wrong?
Thanks

YES! You are very right! But PCB is accurate - schematic is NOT!
I will correct schematic asap and post it again.
I made that mistake in a hurry. Switched pins.... because i used old schematic to redraw new one with another audio...
So..respect pcb, it is accurate (made and tested)..
Thanks and Regards!


P.S.
As you can see...it is tough to be focused on work, various fools distract my attention with their brainless provocations. That's why i didn't answered you just as you posted question...

[ivconic]

"....various fools distract my attention with their brainless provocations..."

Maybe is good idea to replace this subject (as few others) in Restricted forums? Ha?
So we can work relaxed and safe from various idiots?
Because this subject have chance to grow further. I have many more ideas.
Agree?

Than if someone want to join we will reconsider and vote.
Agree?

[ivconic]

I have proposition; to move this to Restricted area. And only old and checked members to have permission to join. I agree (and invite) each old member to join there. We already know who we are , among us. Admin would have very easy task.
Let's vote!

[Ultimate_Haze]

Hi,
Ok.So schematic have mistake.
But because there are no labels on parts I begin to trace.I now that pcb is acurate.But cant figure out which part is which.
If you have labeled view please post.
Don't bug your self with those fulls!Those are just provocations.
Ok for private thread idea.
You have done great work.
See you

There is no reason, my friend, to go on restricted. Your work is the best answer on provokative posts. Dont waste your words for it.

Ok i will put labels on pcb today. I will post it here later.

hi ivconic
how much depth detect for coin and larg target Most Wanted"????

[ivconic]

Ok here is pcb with labels. Hopefully this will help..
