This first thing I would do is check the voltage at the radio. There is a
voltmeter in my K3S so there probably is one in the K3. You could have a
power supply issue or just low voltage in Curacao. I try to maintain 13.5V
on TX.

I was running some stations on 160-meters this morning, and noted that the
power output had dropped from the amp.
Further investigation found that the maximum power out from the K3/100 was
reduced from ~100W to about 54W, with no error messages displayed on the
K3. Advancing the 'PWR' control beyond 54 W made no difference. I stopped
operating, and found that the power slowly restored, first to a maximum of
84W, and then back to the normal 100W maximum.
I assume that this is an issue with temperature? The ambient temperature
was cool (A/C running in shack). I have not noted this problem before.
The fan was set to 'Config > KPA3 > PA nor'. recommended setting for hard
contest use?
