No, sorry, we are not going to split kits in sub kits. But look at it in another way: thanks to this complete kit your other Arduino projects can advance without interruption.

Hi Chris That is really great news :) :) !!! I wonder what was going on ? INPOUT.DLL should also go into SYSWOW64, but I doubt very much that parallel port control of a DDS would actually work on W10, UAC and all that security stuff. I can't think of the last machine I had that had a parallel port on it, must have been an XP machine back in 2005 maybe. Anyway, onto the really important matter, a decent aerial. I absoultely recommend the M0AYF loop - very easy,cheap,quick to build on stripboard, or get a WellGood pcb from George Smart and build an even better loop, but more expensive (not a lot) than the M0AYF loop. Good luck, and let us know how your adventures progress Peter

Hi Luc, no the sound is pretty awesome with these cheap Aliexpress power supplys. They have +-58V and after i have 2x 22000µF capacitors. Now i am very happy with the amp. But as you wrote i think this is an shematic issue you found because nearly in every amp that i saw use only one power supply. If you want i can send you a email with the components i use :-)

Hi Peter, Uninstalling and reinstalling did not help.  Just to try, I made a fresh install of W10 on another HD, and your software works fine. So the manual install wil probably solve the problem! I had a look at the manual install, but the DLL files are at the right spot, they are in SYSWOW64 (I use 64 bit installation) Do the files mentioned from 6) also have to be in SYSWOW64? One thing i'm sure of: Have to build myself a decent magnetic loop, so I can receive less noise and more stations! Thanks for all your help! Chris

I see you use  switched mode power supplies Markus. I hope there is no noise injected in your amps from the switching action of these ... ?
