The KPA1500 uses a more aggressive fan speed table for 6M, versus the lower HF
bands. In general there is more immediate component heating on 6M for a given
power (especially in the LPF and other areas outside of the PA transistors), so
we start the fans at a lower heatsink temp.
Also, when
Sorry for that...talking about my KPA1500.

Is fan speed band dependent as well as temp? My fan was 0 but when I
switched to 6m it ramped up to 2 immediately. Usually anything under 45C
no fan but on 6m the fan stayed on until it got to 35C.

Thre only fan speed option on the LCD screen is the manual setting. When the
fans operate on auto there is no indication other than hearing the difference.

Maybe I've overlooked it, but I don't see a meter display option that shows
the current fan speed. Is there one?

Help:
my fans make no noise at all. my question is: how do you change the
fan speed?
tnx

The fan speed changes automatically depending on the temperature of
the PA transistors. You can manually turn the fans on at each of the
4 speeds (for testing the fans) in the CONFIG:KPA3 menu. Beyond that,
I don't think you can change the speed.
