Very interesting, and complicated, like nature always is.
I have to use the LP filter because the noise at 65 and 80 kHz makes my station nearly unusable. I know it introduces a delay also.
Is there any reason to otherwise keep the pass band as high as possible? I have other noises at 20 kHz but not too bad, but I kept lowering the cut-off even down to 14 kHz. That is why my wave looks so smooth.
I did notice a few weeks ago that close lightning from the Norway coast looked different. Now it makes sense that the wave is altered on the way to Finland from Pakistan for example.
