Splatter on 7191 kHz

This morning, during the RV Service Net on 7191 kHz a strong (S9+20) station on 7195 kHz generated some audible splatter on the net audio as heard at my location. Below are two different displays I captured from my Flex-3000, showing the energy that was received below 7192 and above 7195.

 The above image is the panascope display with the 5 kHz receiver bandwidth setting. I added a green horizontal line for reference to the noise floor on vacant frequencies below 7189. I set the receiver to display the peak received signal at each frequency sample.

This image is a capture of the waterfall display. The elapsed time from top to bottom is 30 seconds, for the window size (not full screen) that I was using. Splatter from the 7195 station is clearly visible above 7195 and below 7192.
