[Elecraft] setting KPA 100 page 48 problem

hello Don,

the measures find
3.600 => 18161
7.100 => 18163
10.120 => 15034
14.100 => 19014
18.110 => 23024
21.100 => 16185
24.930 => 20016
28.200 => 23285
I put a link to a video : https://we.tl/t-rFR61aZsYH

look what happens when I go from 20 to 30M with HI CUR power for a
fraction of a second, 14 W instead of 5W

if I reconcile again the step of HICUR and I have my 5W, surprising! ...

may be related to my breakdown I think?

thanks again for your help
