Can you also send a screen shot that shows the audio input level? I can easily get to 20W on FT8 with the input level around 0db - your power supply is sagging a bit at 14.6V so that could also be a small contributing factor

It is FT8 screen, but I use TUNE mode for this screenshot.

The issue is same with MeanWell PS where is 15V constantly.

It is not about FT8, it is global problem - on FM, in TUNE mode, IN USB (FT8) everywhere

Good morning to all.
In my case the same thing happens. Maximum power 14.7 W. Work on FT8 and Remote with 15 V continuous.
What can happen?

Good Evening,

issue is still here. For example this is screenshot from 20m. Under load the PS giving 15V, current is 3,4A consumption is something like 51W.

Of course I have set 20W maximal output and so on.

Can someone help me please?

Thank you in advice

It is not about VAC, Digital - it is global. Please email Roman @ EE directly. He is very helpful and can assist with ending your frustration.
