Hi Les
I also noticed the phantom SWR indication (jump to 3.4:1 on my amp,
displayed after transmitting - in Rx mode) that has only occurred twice,
and those times when the temp approached 60c. The output does not seem
to be affected - power level stays the same, and no fault condition gets
triggered. My external SWR/Power monitors also remained unchanged, so I
am thinking it is a display-only problem that is internal to the amp.
To try and avoid unexpected ATU retuning, studied the specs for the ATU
memories (page 17 of the preliminary doc) and methodically spun the VFO
across every band, pre-recording in ATU memory the settings for every
band/segment based on its intervals (10KHz, 20KHz, 100KHz, 200KHz).
Thereafter I just let the amp decide what it needs to do when changing
bands/frequencies. Have not witnessed any re-turning.

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
