Yes, the KPA1500 will drop 10% of the output, as it warms up. 1500 drops
to 1350, so you have to compensate with the drive.
I'm told this is typical of all solid state finals (my KPA500 did likewise).
If you're running the station remotely; bump up the fan speed to slow
the drop (or wear
I note my KPA1500 drops power at its temperature rises...
Using FT8, so a relatively high duty cycle.
Say I start at a heat sink temperature of 27 C, and 1,000 watts out; by
the time the temperature is at 65 C, the power has dropped to 893 watts out.
I have a couple of questions about this
Why?

So I did a bit of measuring today. It looks like I only need somewhere around

Yesterday, I finally took the cover off my KPA-1500 power supply, which
has been sitting on the carpet behind my desk for 2 1/2 years. I have a
shedding dog and am not particularly fastidious, so I was worried about
diminished cooling. I needn't have worried - the interior of the supply

I actually have a currently-unused run of network cable that will reach the amp
when it's relocated, on a home run from the main gigabit switch. It's how I
used to feed my old weather station Windows PC before I went to an RPi about 6
or 7 years ago. I can't tell you the last time that computer
