If I understand your situation, you are depending on the rf signal
triggering the change in frequency and tuning. That usually works but
is slower than having the tuning set before you push the transmit button.
Using something like DxLab Commander lets a signal be sent to the tuner
(or amplifier) as soon as you change the VFO and therefore the amp and
tuner can be ready as soon as the transmit switch is thrown.
Likewise the Flex friendly utility DDUTIL will communicate with the
KPA500 as well as DXCommander.

I am using a Flex 6700 into a KPA500 into a KAT500. I have "trained" the
tuner and placed the tuner into manual mode as per a document from Elecraft.
All works well when I stay on a specific band. When I initiate a "tune",
the tuner quickly goes to the preset tuning without a problem.
When I go to another band, for example if I am operating on 40 then go to
20, it takes a second for the tuner to read the frequency during which both
the tuner and KPA500 see a high SWR. The amp then locks out.
I am using the cabling as described on page 10 of the KAT500 manual; but,
instead of Icom transceiver, I am using a Flex transceiver.
While this is not an issue when operating from my shack, when I operate
from a remote location, I am unable to use the amplifier.
Any thoughts on how to correct this issue?
