Hi Tony,
Thanks for your last post.
I think you are wright, I will let C4&C5 as the are now, at least for a while as this seems to work properly.
It also seems that the propagation last night and today was not so generous than yesterday and the night before, as I got only a few local WSPR spots. But wave propagation is so fanciful !
