Hi Patrick, Andrea and Josef,
Yesterday, I took the QFH antenna and split the receive. The resulting layout:
String 1: QFH antenna (split) -> Sawbird LNA/Filter -> Rspduo -> PC 1
String 2: QFH antenna (split) -> LNA4all (no filter) -> RTL/SDR 2832 -> PC 2
The attached picture shows the results from the two strings side by side:
I honestly do not know what I am seeing. I understand why I might
see more lines in the String 2 picture, since there is no filter in that
chain, but why are the lines different in thickness?
