Nice job dekoratör. Are PCBs on sale?

Nice job dekoratör. Are PCBs on sale?

I have the same (home made). I can send you for free. Just give me addres on P.M.

thanks WM6 my friend did for me.

Does any error in this pcb?

Thank you SimonS, at this moment new PCB is over my need, I still have two unpopulated PCB's from Geo (waiting for ...). I asked just for general info.

@dekoratör: As I can see your pcb is ok. Wish you full success with this project.

ok.thanks. I'm waiting for parts to arrive.

I believe that pcb for KPOT2 must be 2 sides with one side to use for shield.
Maybe if there is not the shielding side it makes KPOT unstable. This is the problem that i has with my homemade KPOT. I bought one full unit from Andrew and it works fine.

[reiv]

It`s not true, I have one side PCB and my Kpot is totally stable

[Tepco]

Mine is stable too, on single sided DIP board. With shielded coil (graphite) and proper cable ( some audio stage\studio wire of unknown origin) not a single false beep outdoor at highest sensitivity, even indoor is relatively quiet in noisy apartment flat. Recently I updated newest K3 V12 software to play with multifrequency and different coils, everything works fine.

[Geo]

So.. it is time to play again with my homemade KPOT. I have an original coil from Andrew so i can try it to see where is the problem.
Thanks for your reply .

[reiv]

Tepco, What is Your procedure of making graphit shield? How do You mix it, and witch option You choose- applying on coils or inside of shells?What is resistance of Your shield?
How do You solve switching to others capacitors changing freq.?
I`m using S-VHS cable coaxial with two seperate shields.

Lately appears on Andrew`s webside some note under the scheme:
КУ усилителя приемного канала 50-80 подбирается R10.
Земли можно не развязывать -> убрать дроссель Dr1.

It is about R10 and Dr1 but what does it mean?

[WM6]

Mean that:

(A) amplification (gain) of receiving RX channel should be 50-80 and could be set by value of R10

In case that Krot2 ground balance is impossible, remove choke Dr1.

[Geo]

Hey Jaka. how are you???
Why dr1 at KPOT2 is 10uH and at KPOT3 is 33uH??, it has not anuthing to do with the frequency...
