[Elecraft] K3 temperature

[Dave Hachadorian]

Speaking of temperature - A week or two ago I complained 
about the fans continuously speeding up and slowing down 
during a contest. Since then I have set the fans to run 
continuously at low speed (config kpa3=fn1). The fans are 
almost inaudible at this speed, and I didn't hear them 
cycling up and down during the 160 cw or bartg sprint 
contests. The rigs were running only 50 watts though, 
driving high gain amps.

The NAQP RTTY contest is coming up on Feb 28. That's a 100w 
RTTY contest. The rigs will get a workout there. I'll keep 
an eye on pa temp and fan speed.

I did verify that with kpa3=fn1, the fans do speed up if pa 
temp rises.
