Dbanner I wish to do the same. DP has to prove it self before i decorate it. My worst fear is that the two meter cola can detection is contingent with extra terrestrial conditions. Mr KT has been cooperative and proven his expertise and i hope we can complete the project soon but so far i haven't got a clue about where the enclosure is grounded.

DB i show you an old pic of camaraden who did read my suggections and did sure i wrote him. JUST EXAMPLE.
they are living in wood, they doing all from wood, they are birth the wood.
and you can not do something with that! even they do helicopters and airplanes from wood.
wood is that is around all their life there. only wood and the foil they are know good. and slightly chinese transparent thermo glue
they use in every their job/crack, where needed and where not needed.

Dbanner that's what i am going to do. Do i need to ground the metal enclosure? With what point on the board?

KT315 will tell you everything you need to know about Delta pulse. He is the expert on this matter of shielding.
Do not put beautiful woman in crocus bag, she will not be happy. Put Delta pulse in good chassis box!!!
You have done very good job thus far, you need to think "big". Reward your efforts with professional looking device.

Man, can't you find some aluminum box to use for your enclosure? Journey to nearest city and walk around the town, keep your eyes open wide.Look for proper chassis box. If you insist on wood box, use copper clad board for shielding.
Use ordinary Elmers white glue for mixing with graphite powder.

This DIY graphite powder is a nightmare. I give up. Now looking for alternatives

Make a 200-500ohm graphite screen with wood glue+water or coating enamele lacquer, composition 3:1 add more glue+water/lac when too thick. Dry it, test, add more layer as needed.

Don't forget to sanding for better bond

Treasure hunting season has started and i have already missed a trip to the field. I have to complete this project as soon as possible.

do a big pause. simply relax.

Dear careful don't burn yourself.

The graphite coating is also connected with the board?

Do you know how advanced jets avoid radar detection?

[kt315]

Don't jerk in my side. burn wood in the oven and boil a caffee on the night job.
