Vellman CW (Morse) decoder

Couple of days ago a friend of mine post add, selling his almost new Vellman cw decoding kit. I miss a moment so my other friend bought it. Today he make a post on FB that show this thing actually work despite all bad copies made from China :)
I google a little and I found schematics for this great cw (morse) decoder so I decided do make a "footprint" of it on my blog.
I hope someone will find it and use it and find it interesting too.
Enjoy.
