There is a couple of openings at 0149Z every evening "NIghts" in Europe. Italy unfortunately is at the lowest part of the path but
manageable as we used to have one in the past. Here all the North eastern part of the continent is in the path too.
As you said it is the night in Europe that's explain why there is very few stations available but it take's only a reminder to have some
folks awake and on Friday and Saturday night it could be the best day to have some Europeans friends on the air!
I will give a try tonight.
On a different subject i have the same VHF antenna here "KLM 2M-14C" and the polarisation relay became open did you ever have to replace it
on your antenna? Seems to be not an easy task!. And finding a suitable relay even more difficult.
P.S. I am usually in the middle of the downlink pass band on FO-29
