Γεια σου Bill. Δεν ξερω τι ενοεις CW αλλα σαν παλμικο θα δουλεψει με ενα πηνιο στο δεκτη. Εννοειται πως σαν παλμικο δεν χρειαζεται τα πηνια να ειναι καθετα μεταξυ τους.

Hi

Nelson,What did you do with TR circuit & coil?

[Shahab]

Here is my TR circuit:

TR locator

Hi Shahab.
My circuit need a few components to get ready. Today i got it and tonigth i hope i can finish it.
About the coil, i m working on the support and coils, so i think i ll be ready to make field test may be this weekend.
By the way your circuit is nice. Have you made any expirencies with it?
For Gary: Gary is possible to put those 0.4 and 0.2 caps together with each coil instead of placing them on the board. This i think is an easier way to replace them to get tuned both coils.

Nelson

Nelson,i hope that you finish your circuit.

I built some PI detector but TR Locator is my first detector in TR mode &

I don't have any experience with these detectors.

Hi Nelson, YES, Those Caps Mount on the Coil, Not on the PCB.
And There are No pads for them on the board.

Your T/R Board and REG1117A will go out in the Mail Today.
You Should get them in About a Week.

Take care....Gary

Ok Gary, what a stupid mistake i have done, yes i didn´t look that, the caps go of board. Sorry for that question.
Tomorrow i ll go con a money exchange bank and after that i ll mail it for the two reg1117a.
In advance many thanks

no. because coils are in one plain. you will get overloading in RX look on TM-808; TF900 and Gemini-3. their coils are orthogonal each other.

[Bill512]

To Geo and kt315, thank you for your replies.
to Geo: CW is continuous wave ( γεια σου Γιώργο , εδώ Pytheas )
to kt315 : I know about the “standart” two box design. I had the TF900 but it seems these detectors (TF900, TM808,Gemini, Garrett…) are not good enough for treasure hunting in real conditions. The TF900 it will easily pick up a (25cm x 25cm ) iron sheet in 60cm inside the ground (tested) , but olso it will easily pick up “ ground signals”. The 90 degrees Tx-Rx placement it seems perfect only on air tests. Also do not believe that those reports from companies ,about depth capabilities, is truth.
Some other tests on ground (metal mode) :
A) iron sheet (30cm x 15cm) in 120cm depth : not detected
B) iron sheet (35cm x 37cm) in 155cm depth : not detected
C) two aluminium engine cylinder head’s, say (43cm x 30cm x 15cm) in 170 cm depth (top) : not detected

hello Bill.
try load this book. it is in russian, but you will find the copy very informative in particular of two box design of Andrej Schedrin.

How can I read a ".djvu" file?
What program is needed?

[kt315]

amazing that you do not know about this format. all www archives use only the format. magazines, books, schematics etc. - all I see in it.
visit http://www.lizardtech.com/
really for DJVU there are very much kinda converters, viewers, plugins etc.
I think you can try to ask your neighbour anyway. because I can give you only links on russian resourses. I even do not aware what is a best soft for it... a standart is SOLO.

Hi kt315,
Yes - it is amazing, but I have never heard of this format.
I have downloaded the Internet Explorer plugin and now it works ok. With the assistance of Babel Fish, I can even understand the text - more or less.

Thanks!
