echoes etc and that's not easy. You might use an indoor antenna, but the

Indeed. But i think i should go through the whole tuning procedure again.
But unfortunately, a day has only 24 hours and i have to earn my salary as
I hope that i can avoid a manual offset compensation. I see the problem that
