Irwin,
The PA temp calibration is, as Don already stated, in the manual.
Just wondering, do your fans actually run?
The fans can be tested in de menu: KPA3.
If set to 'PA nor' then the fans are temp controlled.
If you turn the main dial, PA Fn1 - Fn4 will come on the display, You
should hear the fans running.

Thanks. I will reset the PA Temp to a lower setting. I am finding that once
the PA temp gets to 27C, it shuts the 100w amp off and I only get 10W out
of the radio until it cools down. Even at 70W output in RTTY, I should be
able to keep the temp down with the fans? I am wondering if I have
something set wrong?

Irwin,
Yes, I think that PA Temp setting *may* be too high, but it 'all depends'.
The PA Temp indication will follow the actual temperature of the heatsink,
so if your K3 has been on for a while, that 27 degC may be normal.
Follow the instructions in the manual to set the temperature.
First turn off the K3 and leave it off until the heatsink acclimates to
room temperature (at least 15 minutes, I recommend 30 minutes).
Then turn it on and go to the PA TEMP menu - set it to the room
temperature in degC. For a 73 degF room, that would be 23 degC.
If I recall, the fan will not turn on until the PA Temp reaches 40 degC.
If you want the fan to come on sooner, set the PA Temp to a higher value.

How do I set the radio to turn on the fans when then 100 w amp temp gets
to
a specific temperature. I am playing around with the RTTY contest -
running 70 watts output into a tuned antenna.
With KPA3 set to NOR, the fans do not seem to turn on, even when the 100W
amp gets to high. I know the fans are working because when I set KPA3 to
FN
1 to 4, then fans run continuously at the appropriate speed.
PA temp is set to 27C. Should this be lower?
