I should point out that I have left the fuses on default which I believe gives me 8mhz but looking at the scope, maybe I am mistaken!
As before, any help or pointers gratefully received.
I had a few problems with the ouput signal and it turned out to be my signal was inverted. So added a few extra parts to invert signal and worked great and i'd done nothing wrong. I'm using Futaba gear but may apply to UK spektrum gear?!.
