Thanks for answer me, I researched a little but my search results not include the PCB image. I find that many post talk about the corrections in the pcb, but I not find anything that show the complete image ready to print in the board. I have bitx40 diagrams, the problem is that here I cant adquire the bitx40 kit and for this reason the circuit board has to be build by my self.

Best regards, CL2LKY.

The PCB artwork was NOT published for home brewing.you have to manage from the photos re entering the schematic and re doing artwork on some software like eagle, express or dip trace etc.

the corrections can be had from here
http://amoghdesai.com/technology/electr ... t-to-know/ check from approx halfway down

all the best

Thanks for answer me, I have problems to access on this url. I cant access to yahoo because the domain is denied in my job center and this is the only way to browse in internet that I have.

if you would be so kind as to share that information through email or other way, I will be very grateful.
