Great to see it is working, looking at your station 3378 I do think you need to experiment with the gain settings.
I don’t know what RF chain you are using: Antenna type ?? -> LNA ?? -> coax type/lenght ?? -> SDR
The E4000 has some specific gain settings that can be used, but can also be confusing.
There are more stations using the E4000 search on the community pages to find some examples.
Here an example of a station that was also having some issues.
Good luck,
