No issues of that type here. These are my setup numbers:
Baud Rate = Eight
Stop Bits = one
Handshake = None
PTT method = CAT
Mode = Data/Pkt
Split = Rig
Also under the Advanced tab: Miscellaneous
TX Delay = 0.1 sec.
I'm not running any other applications such as JT Alert, N1NM, etc.
Hardly. There is no delay adjustment for VOX activation, just sensitivity.
if the VOX sensitivity is set correctly, activation is virtually
instantaneous. It is the VOX release where the delay is adjustable.

But there is a delay in WSJT-X. See the F2 Setup, Advanced tab and
Miscellaneous. Make sure the TX Delay is set to 0.1 sec. This is the
time delay between PTT and start of audio. Also, if one uses CAT
control, then be sure the VOX on the radio is OFF. Don't use both.

Understood, Bob.
My point was that in the radio, with the VOX correctly adjusted, response to a
transmit command using VOX is virtually indistinguishable from PTT. Any
significant delay is on the release. Agree with you that PTT is the better

The most common cause of "not coming out of transmit" is that you have 2
sources of PTT.
VOX and CAT, or VOX and RTS, or CAT and RTS, or any other combination.

Here’s my latest attempt:

Most SWR meters accurately read 1:1 with a 50-ohm resistive load but may
not read accurately at higher SWR. That normally isn't a problem: when
you're tuning an antenna you are aiming for lowest SWR. The exact SWR
isn't important as long as it is minimum.

It appears that the higher voltages at QRO are enough on return to fault the
amp. That could be an arc or the match isn’t really 1:1. Using an antenna
analyzer at the balun would be useful.
If you’re on 80M, without the tuner, you’re likely to see ~3:1 untuned at the
balun, within the range
I’d guess that something is going on in the tuner. Maybe a leaky gasket and
