WSJT-X has provision for changing the delay between assertion CAT PTT and onset
of audio (settings/advanced/miscellaneous). The delay between end of audio and
CAT PTT
My Winkeyer has settings for both lead and tail time, and so does
N1MM+. WSJT-X does not appear to have these variables.

Pete, have you tried increasing the transmit delay between your exciter and the
amp? If the exciter continues to transmit briefly after the amp’s relay kicks
out, you could see an swr spike.

I don't have the same equipment as you but I experienced a very similar problem

when I looked at the output of my TS-590S with a scope and spectrum analyzer,
I found that it was emitting out of band spurii at the end
I've been operating 160M FT8 recently, and am noticing some odd symptoms
from my amp that seem only to occur in FT8 mode. Even running only
about 1170 watts into a good dummy load, with the KPA-1500's ATU
bypassed and a displayed SWR of 1.0:1 during transmit, as soon as the
transmission ends
