Audio distortion after a few hours

[Dave30019]

I've owned the 7K MKII for 3 1/2 weeks and this issue started after 2 weeks. After the rig has been on for about 2 hrs or up to 12 hrs I start getting distorted audio. I tried a total of 3 different sets of powered speakers, same issue. This occurs on both FT8 & SSB. Not sure what to do. This example is a mild version of the distortion.

What does your spectrum look like? Especially the FT8 transmit spectrum when this happens?
I find my ANAN 100 frequently starts generating noise similar to this and I have to toggle the power button in Thetis to reset.

It has nothing to do with your speakers, trying a different pair will make no difference.

How are you feeding those speakers? Are they plugged into the 7000, or are they plugged into the computer and you are using VAC?

[Dave30019]

The speakers are plugged into the front headphone jack.

Unfortunately I haven't any good suggestions. I hate to suggest resetting the database...
