[Elecraft] KPA1500 fan sequencing

[Mark Musick]

The simple answer John is "Yes". Your KPA1500 cooling fans are running as intended.

Is it normal for only the middle fan to run on the KPA1500 in Level 1? expected all three fans to run, and simply increase speed as needed to efficiently (and quietly) provide the necessary cooling. All three fans do run in Levels 2-5.

Is this normal?
