first, let it dry and then seal with epoxy.

Another tip for high gain circuits is it is important to clean the circuit board and solder joints after the soldering is completed. A thin film of solder flux left on the conductors can make a path for electrical leakage in the high gain sections even when you cannot see the flux. It is common practice to clean the circuit boards with methylated spirits and let it dry before sealing it with coatings and potting. The cleaning of the circuit can also help when tuning the circuit so small signals are not lost with electronic noise from leakage across the conductors near the transistors.

You should be careful when choosing your words, now gurus are going to be needed to to clean the boards from spirits traces...

that is good ideia,is some kind of verniz spray,it will isolate the circuit and then pot with epoxy ,thanks

,yes,it will be a problem if Jinns stay around the LRL circuits.

This is not a problem for you. I see guru printed under your name.

It have to be dedicated to insulation in electronic. Not all spray lacquer are suitable for this purposes.

Well it looks like no one will build me aSuper Pistol LRL on this forum.

Morgan was going to but has changed his mind, but I respect his decision.

I therefore have decided to build one myself with the help of a qualified electronics engineer.

If anyone hear would be happy to help me in this project then please PM me.

I would be grateful for your response on what you think would be the best and most up to date schematic pistol to build.

Of all the schematic LRL`s projects on this forum I’m confused “do any of them work or not” the only one that comes to mind is Morgan’s video finding his own sample target, but is there any other proof videos of actually finding a good target.

I have some good areas hear in the UK to search for old buried precious metallic treasures, so would be happy to publish all my field test results hear.

I want to join with you in a treasure search with PDK in this places,i hope to visit your country very soon.

Morgan,

I look forward to searching with you on your visit, and very interested to see how your PDK performs hear.

One thing here is Humidity is quit high at the moment it’s about 78-90%, in summer it doesn’t get much lower than 65-70%

I believe this can cause problems with PDK detection range?

No,it works fine even with high humidity.
