" i did think ak48 meant FISHER IMPULSE while now i see it is simple shiff sniff. "
it's the Mole Impulse Pro and not XR71 or anything else as you can see on the pics , thank you
power transistor :IRF 540N

I think KT315 is asking that you don't post the schematic until AK48 has posted photos of the PCB. He wants to build up his archive to 18TB.

thank you George. you are perfect mindcatcher.
my mistake. i did think ak48 meant FISHER IMPULSE while now i see it is simple shiff sniff.

[КУОТЕ = ецлипсе; 280943] Не желим да кварим ствари, али та плоча изгледа исто као кр71 сниффер. Поред тога, у горњем левом углу можда постоји регистар напона и можда ниски цкт бат, али то је опет стари кр71. [АТТАЦХ] 53295 [/ АТТАЦХ] [/ КУОТЕ]:палац: Yes xr71

I dont want to spoil things but that board looks the same as xr71 sniffer. As addition there might be a voltage reg on the top left and perhaps low bat ckt but thats the old xr71 once again.

Ah so!
And yet i don't know what schematic it would be!??
Don't have a clue.
I saw posted photos of pcb in meantime and i don't recognize it.
On the other hand: i don't remember what was yesterday... not to mention what happened in the past.
Too occupied and focused with what i am doing now; all other things faded completely from my mind.
(I am using some meds on daily basis that helps me a lot. Side effect is lost of memory and memory with huge time holes.)

I don't understand you at all?

[kt315]

i need 18 tb archive value.

stop give the schematics. just AFTER HIGH RESOLUTION SUNNY DAY PICS OF THE BOARD.
THIS IS the FORUM. THAT IS FREE EXCHANGE OF INFO.
did Dave Johnson give you the pics FREE and schematics from his archive?

The Impulse was a commercial product, not a do it yourself hobby project. It's possible to strip the design down to about half of what you see here and still have a fun little PI. I'll leave the details to others, sorry, I don't have time to mess around with a hobby project.

In my experience this basic topology is a very forgiving design, back in the 1980's I built many variants of it. You can do almost anything to it, and if what you do isn't really stupid, it'll probably still work. So don't be afraid to play around with it, this isn't one of those projects where everything has to be "just right" to work.

What archive KT315?
You got me totally confused and lost!
Nor i know what this topic is all about?
Dave Johnson gave us occasionally few crumbs of good advises "poured" with a lot of arrogance. I don't mind.
As far as i am concerned; he owe us nothing... but than again we also don't owe him nothing too except basic respect.
But this all conversation is making no sense to me at all.
I don't know what are we talking about here!??

i have to grasp Impulse is PI or VLF. LOL!!!
