I've found an issue with pure signal, very visible, when using 2TONE.
If you adjust pure signal at a very low drive level and then you try to adjust for a full power output, PS produces a very wide 300Khz splatter/spike while auto ATT is trying to find the correct value.
Same issue, but not as clearly visible, when PS auto adjusts using your modulation.
Tested in my Anan 7000DLE/Thetis 2.10.3.4 and also in an Anan 7000MK2/Thetis 2.10.2.2 from a friend of mine.
First time I saw this issue was 15 days ago when going from low to high drive power on 15m. After the spike/splatter, one of the LDMOS transistors in my power amplifier was damaged because of a fast SWR trip.
Is anyone else experiencing the same issue?

I was asking people before posting to GitHub to confirm if it is a wide spread issue.

That is completely normal behavior. That is how PS has always worked. As @mw0lge wrote, it takes a finite amount of time for PS to analyze, adjust and implement a correction.
However, it does beg the question of whether anything could be done to make the process more graceful. But in the meantime, again know that this is "normal".

I understand that PS takes some time to adjust.
It could be me, but I don't remember to see that 300Khz wide splatter when PS was analyzing/adjusting.
Thanks anyway!
