try retune to 10us strobe delay min. for gold nugget you have to use 16-18cm coil.
learn double field coil infos.

I greet Mr. KT315 these values are real or is it a mistake

[kt315]

these resistors might being taken in very large range. if you take R40=1k (look sniffer xr-71 schematic) you
get more fast SAT nulling and without sound in the process. if you take 10k you hear the slowly descending sound
(pressing RESET knob). anotherway you choice yourself what you wish =)

many thanks.

Regards Mr. kt315 ...... For the best performance of this Project, can you tell me approximate what the values measured on points T1, T2, T3, T4, T5, T6, T7?
Thank you and a good day.

[kt315]

look the diagram.



T6 reaction in negative
T7 reaction in positive

I read the board from head to tail and no one said anything concrete about A frequent adjustment and coil values.

Is anyone able to tell which is tuned for optimal A frequent IRF740, value coil resistance, coil inductance value, resistance value dumping?

thank you

[kt315]

all had been told many times. you do not wish to read this thread - laziness of mind, yeahh?

100 PPS Hz for EU with AC electric standart 50 Hz.
120 PPS Hz for USA with AC electric standart 60 Hz.
300 PPS for Sniffer XR-71 for any country.

Mr. Phil do you have scheme of for this pcb mode?
greetings

[gaby_sult]

with respect Mr KT315, which is correct?


What do you think about this mode ?

i understand your delusion. simple rule - you have to look on the coil wires at first. cold end is used for shielding.
so for N channel mosfet (E+) is cold end.
i did not intendly name +E as ground... just cause the schematic will be looking unreadable for dummies...
if you look Hammerhead schematic you will notice what i mean.

i did check with the resistor - did not feel a difference. in my opinion that is a protection of mosfet if vd8 vd 9 breaking off.

Ok I understand but:
I read 126 pages twice to understand nothing.
With respect, I put this question with the intent to understand why you published schemes are not the same with your assembly (PCB).
I know that each influences the value changed for better or worse performance of a project.
Why not post a schema with the exact values for the best sensitivity and performance of this detector?
And now a few examples:
