FLEX 6400 : CW signals have a lot of distortion. I am trying to figure out if there is something wrong with the 6400 or if I am doing something wrong on my end.  At first I was saying "wow that guy has a messy signal.  However I noticed that any strong signal had the same characteristics.  I have a video that show this issue.  Can someone have a look at the video and give me a second opinion?
BTW Wide band Noise Blanker disabled, also no other filters enabled.

Russ try cutting back on the AGC-T.
Also make sure WNB is not set too high.
Betting on one of the two.

He stated his WNB is disabled. I tried to replicate with my agc-t set to 100 and
added in 10 db of preamp. Could not see that here. Good luck.

Thanks for the replies.
Update:  I turned off the 6400 over night.  This morning signals were "normal" - no distortion.  After a few hours I checked again and the distortion was back.
I have submitted a ticket for this.
