Carl,
Not sure about the KPA1500 but I believe the limit on the KPA500 is
90C. It is normal for the fan to come on and speed up automatically at
particular temperatures. I set up some of the macro buttons in the
KPA500 utility for various fan speeds. If I run a high duty cycle
digital mode, I will kick the fan up on the highest setting before
operating. Don't think I have had it up to 75C, but it will usually run
in the 60s if making lots of back to back QSOs.
73,
Mike - KI0HA

Tried full power on 20M FT8 this morning in order to work weak Russian. Temp
gets as high as 75C. Loud fan kicks in. Hope this is normal.
