[Elecraft] KPA500 - Fan running fast

[Michael Walker]

I run my KPA500 remotely... very remotely

There are times when I am running at full power in a carrier mode that I
turn the fan on high manually.  Which is pretty funny when it is blowing
-10C air through it.

Then, when I am done, I turn it down.

But.. there are times when I actually get to the remote station and find
that that fan is still running at high speed even though all the remote
controls show it at low speed.

Has anyone else notices this?
