Interference Signal in FM range

[Srinivasan Srinivasan]

I opened post about noise to listen FM. I checked further using different tools.
I can see that sudden increase of RF and down ( you can see in blue color ).
I suspect some external RF try push the quality of the signals.

Attached file for your reference.

Any chance you can decode or other details.
