No Problem, all are the same because the total consumation is lower than 100ma

[abdou2014]

Thank you Geo !

[Geo]

What preamplifier do you use???

[abdou2014]

Your Email ?

[abdou2014]

I have never used the audio stage, only the VU meter and I detect a magnet at 1 meter and TOTEM transmitter at 5 meters, I do not know if the 4066 + 555 will give more amplification or sensitivity ???

[abdou2014]

I have not yet received the email from Géo ???

[Geo]

If you wil look at my profil will see it!!!

[abdou2014]

Excuse me Geo, I didn't know

[abdou2014]

Is it possible to work in VLF ?

[Geo]

who???

[abdou2014]

I'm talking about ANDY FLIND MFD , if yes , is the 16cm Coil is good for this range or we must work with ferrite ?

[Geo]

Yes it is possible to work at VLF.
I believe that it will works the same with ferrite or with round coil.

[abdou2014]

Thank you , I want to know more about 7.1 Khz that you use with your best LRL ?

[abdou2014]

I believe that the two 15cm Ferrite rods have more sensitivity than all the antenna, I made an experiment with it once and I was impressed

[abdou2014]

it's not to say that I'm right, I believe that the 15x2 rods gave great results than other antennas only in the circuit I used, and the Antennas gives equal results with Andy MFD

[Geo]

One Ferrari is better than a Lada jeep at good road but at mountains the Lada is better.
I mean every thing for his job....

[abdou2014]

you are right , check your email ?

[abdou2014]

Flat spiral tesla coil gives more sensitivity, 7 meters from the transmitter , I think it needs to be converted to infrared

[abdou2014]

[Geo]

Does it "see"the watch now or you want to post a video from an old member???

[abdou2014]

give me a little time I will make a historical modification

[abdou2014]

Oops, the batteries have dropped, it's a pity I still have not detected the electric watch, but I have good results

[abdou2014]

the watch I used has no coil, it is not normal with this high sensitivity and I have not been able to detect it, I think it must this model ???

[Geo]

If your watch is n't the proper... use a wall clock... they have the same machine.
