Subject: [Elecraft] KX3/KPA100/Powerwerx Question
I have a KX3/KPA100/Powerwerx setup. When I run the rig with the amp on, my
Powerwerx 30 amp power supply makes a whirling sound. If I run the rig without
the amp, the power supply makes no noise. When I run may K3 it makes no noise
I suggest taking the lid off of the power supply and inspecting the fan for
dust. It can accumulate and affect the free rotation of the fan, generating
noise. A vacuuming might be in order.

Maybe it’s the cooling fan of the power supply. When more power is needed the
supply gets warmer and the fan spins faster - so you can hear it then. If it’s
too annoying, there are more quiet fans with which you could replace the
original fan.

Is there a problem causing the noise?Thanks,Jim W7JHR
