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...

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?
