Thank you all for your valuable informations. Yesterday, I carried
the IC910H into the garden and attached a Arrow Antenna directly
to it. Then I listened to AO-7 and FO-29 pointing the Arrow
roughly into the right direction. The result was amazing: I guess,
I have not heard such good signals since quite a while !
So, it is clear, that I must first fix my installation - I have
obviously a problem, which reduces my 'hearing' and I must have
become used to the bad situation over time.
Then, as some of you suggested, I may have to reduce the preamp
gain drastically and can probably go without them.
This will take some time. I will document my findings and inform
Thanks a lot and 73
