coil generator : tester of coils

[Tibuck19]

nice. i am glad. let see your solder process and result. i will put some pics of board at near time.

Well do thanks

Perfect!

Stupid question time, How do we know what Cap to put on C ?

[kt315]

if you do not know is there a cap inside a coil or not connect a cap with 1% accuracy. russian uses 10nF, like a standart. i use 5% accuracy, do not have less.
i had gave the pics. look this pic on right side a value "C=10N" - is 10nF
and he gives values of resonanse he measured for rx and tx.

all tesoro coils do not have a cap inside, while i do not know lobo coil, no data.
whites xlt coil has a cap on rx and tx side.
if you have tx like colpitts generator you can take same cap or desolder this cap from detector board and tune with it.
you have to see sure a frequency of your detector.

Great quality of PCB, but I need help about value of electronic condensator and transistors which are npn and which pnp. I can't find nowhere on the posts those informations or electronic schematic

I found it on first post, now everything is OK

npn vs pnp

E - emitter
B - base
C - collector

pnp and npn

Kt, Would it be possible for you to post the Gerber file si I can try to pen mask a board and compare it with the one you sent me please. Thank you

compare for what? i ordered just one batch. from this batch one pcb was soldered and demonstrated for GTers.
there is not mistakes if you mean mistakes. gerber files is not graphic files and how you open them, by what soft?
installed CAM350 to look just one sided primitive pcb?

Sorry I should of specified, the .gbr I would need the file and not a image of it , A file with just the traces and and holes for top CU layer, I want to pen plot it with the plotter I made, I would like to compare the traces with one ill pen mask and the actual board you had sent me a while ago.
