[Elecraft] K2: KPA100 fan

[Randy Moore]

Today I worked the Ala. QSO party, and was able, most of the time, to 
hold a frequency and call CQ.  I started out running 90w (measured on my 
Elecraft W1 wattmeter).  Then after just a few minutes the fan started 
running.  I was sending at 24 wpm with 4 seconds between CQs, plus 
whatever the actual QSOs took.  I backed my power down to as low as 60w 
and the fan kept running even there!  Is that normal?  The ambient temp 
was 78F, and I had checked the tPA calibration earlier in the day just 
after turning on the rig.

Also, I noticed that with my power control set to 60w, the actual output 
(on the W1) varied up to as much as 80w.  Is that normal too?

This is a KPA100 that's fairly new to me.  Its built into an EC2 
enclosure with a KAT100.
