[Elecraft] Thermal control for Q1 / Q2 in KPA100?

[Stan Rife]

	From the description of the noise that the fan on your KPA-100 is
making, I'd guess you have a defective fan. I never hear the fan on my
KPA-100. I have a pretty quiet shack, and operate with the volume fairly low
on the K2 and I have only noticed the fan running a few times.

Whizzer - what a good name.  It actually startled me when it came on and
the noise interfered a bit with copy of the weak station I was working.
I may have to go to closed headphones.

The MEs here at work tell me similar things.  Some of the pads are
better than grease.  Good, grease is a PITN (neck) to work with.

I'm also glad to hear the pad reflows when it gets hot the first time.
That answers a concern I had that maybe things just aren't tight enough
yet.

I have a few muffin fans left over from a PC build-up.  I think I'll set
something up.  The 60 deg air in my basement plus some fan-action should
keep the whizzer under control ...

Thanks Ron & others.

73!

You aren't the only one to be bothered by what I call the "whizzer" on
the back of the K2, although I confess I'm getting used to it. Sort
of...
