[Elecraft] KAT500 question

[KD7YZ Bob]

Howdy K3' people:

I have a KAT500. The "Auto" green LED is lit. I have previously tuned to
the best it could get on 17m.

This morning it is drizzling. The 450 ladder can sometimes act up when
it is raining.

So I begin a JT9, one-minute long, sequence. Next I hear a little
chatter and see the Red-LED come on for SWR>=3.

The "Auto" LED is now flashing. No tuning is taking place and the
one-minute transmission finishes.

I press & hold the XMIT/TUNE button and the KAT500 finds a nice SWR of
1.1 .

Next sequence comes around and the K3 switches to xmit. The KAT500
chatters maybe once and the Red SWR LED comes on again. The "Auto" LED
is now flashing. I can do nothing about this while the K3 is
transmitting. Technically I should kill the XMIT and correct the SWR
problem. We all know this.

Fortunately I was running  but 5 watts on the JT9-1 mode so I don't
believe I did any damage.

When I used my Palstar AT2K tuner, and it was raining, I'd see the VSWR
climb, and knowing the cause, would just manually turn a knob and keep
the SWR down. Was jut something ya do when it's raining,

Is there something I am overlooking with my new automatic-tuner?
