coil generator : tester of coils

Ahh! Thanks KT. Now I can make for myself. I am working on new project called Beach bug/Goldhunter @20khz. May need your expertise.

[kt315]

certainly DB. only copy the layout in sprint-layout and do a hotdog. i will still check it and then will order the pcbs.

i give some pics from russians. you see a resonance value of rx and tx.

[dbanner]

Yes I see. Russian guys are very smart.
Now with coil generator circuit, I can be smart too.
All Now I have resonance frequency of both tx and Rx, checking one at a time.
The cibola tx is very high.
We're these measurements taken with C1 50 pF?

[dbanner]

No couldn't be. Looks like they measured using caps values from schematic unless coils have internal caps.

Good for VLF or IB coils also ???

[kt315]

good for all tipe coils - vlf ib bfo pi etc.

Great when are you getting these little boards made ?

[kt315]

ahaha! look on my screen

[kt315]

received the boards batch. have to solder and test.

It will be interesting to see what transistors you choose and if a PI coil will oscillate with out C1.

Are those transistors and resistors you used from recycled Electronics ? Keeping true to KT ways? Looking good so far.
