[amsat-bb] Re: searching advice on low hpass filter for 146 MHz

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 you afterwards.

Thanks a lot and 73 Werner, HB9BNK
