Well, reducing the amplitude is easy, but things become interesting with
echoes etc and that's not easy. You might use an indoor antenna, but the
results might not be reproduceable.

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
well...
I hope that i can avoid a manual offset compensation. I see the problem that
if i want to implement it in the tuning procedure, i need to wait until
the decoder has locked and this might take long.
But if i come to the opinion that i need to do so, i will come back to your
proposal.
Best regards
Hartmut
