Thanks Gerald et al. Turning off the NB did the trick.
So..because the NB operates over the entire bandwidth..I don't fully understand why that would make the noise floor jump due to strong adjacent signals. Sorry I am sometimes slow on the uptake.

Mark, AGC operates only on the final filtered bandwidth so pumping from other signals does not make sense. Do you have the noise blanker turned on? That might do it since it operates on the entire bandwidth.

IARU HF championship. I notice that with a lot of strong signals, it seems to be overwhelming the AGC. I have the preamp off, ACG settings don't seem to matter and neither does the AGC-T setting. The symptom is that the background noise seems to jump in according to strong SSB or CW signals within the 96 kHz passband. Any thoughts or comment?
