power varying - KPA1500

It is quite easy to determine if the K3S's output is dropping.

When running the KPA1500 at full power, sometimes the power will fluctuate.
EXAMPLE: I was checking in to the Elecraft SSB net a little while ago. While
transmitting, the power dropped to around 400W. This has happened on 20M CW
as well. I wonder if the K3S output is dropping. (??).
If I run at 500W or so, no problem.
