Les,
Possibly "power drift" in your antenna? Sometimes trap antennas have ceramic
capacitors which drift under high power. Try a dummy load, etc. I think the
SWR threshold point at which the auto tuner makes correction is adjustable
in the amp. Try setting it up a little higher? Please let us know...

Subject: [Elecraft] First impressions of KPA1500 #113
Arrived May 5th and setup was easy. I’m noticing periodically a momentary
higher than normal SWR indication on the SWR bar graph. And I’m still trying
to get used to the ATU. I’m experiencing the ATU having to make adjustments
sometimes at the start of a transmission after the ATU has already been
properly setup for the antenna and band. Is anyone else experiencing
anything this or am I doing something wrong?
Les, N1SV
