Hello KT,
He wants to know what size coil to use. How many microhenries?
Cheers

guys
if you buy DP board you can always ask me to put DVDs with archive for just 4 euro of additional price. i also give a link on full
folder of files. why you can find those files in it? laziness? folder HUGE COILS. NO SECRETS AND NO FILES I DO NOT SHARE.
those standart tables everybody gave and gives them in every threads on coils and a PI detector everywhere.

the think is that you dont understand that some people like me are new in electronics and they dont have anyone to help so any file any information is importand
anyway i make the device to work and this for me is huge step and thank you for your help

good. now tune a frequency on 100 Hz sure with PPS pot on board by frequence meter. set a probe in T2 or T3 control point.

The maximum I can get is 95

why 6.36V? power supply voltage is 12v -0.8v diode ->11.2V. minus losses - you must see 10v>

The maximum I can get is 95

change c1 on 20 or 18nF.

I received my new oscilloscope tonight I will install it to my pc and I will measure again to be sure because I don’t like this oscilloscope it seems that doesn’t work so well and if I see the same results with the new one I will change directly I have capacitors will this values

I made it I have 10,7 volt stable

[Kubi2323]

Now?? How can I increase the sensitivity

[kt315]

sensitivity in DP is tuned by pot DEPTH (old name noise). also, set DISC at minimal.
DISC is in reality FIRST SAMPLE DELAY.
why 10.7V if needed sure 12V? DP is not working with 10V.
for 500us PULSE WIDTH you need good capacity of battery with low inner resistance.
