Eric -- this is not at all normal! My PSU is quiet...hardly hear it from
under the table. I understand Elecraft changed to much quieter fans maybe
two years ago. But even so, perhaps the voltage to your fans has soared way
to high? I haven't looked at the circuit driving them. Maybe lost
regulation, etc.

Apparently I was not clear enough in my message. It is the PSU fan noise
that is deafening, not the RF deck. Like Peter, my PSU sits on the floor
underneath a wooden operating desk that holds the rest of the K-line. The
noise from the PSU is high-pitched and piercing. The only thing I can
liken it to is a four-rotor Mazda prototype IMSA GTP race car from the
early 90s. Brain-piercing, tear-your-hair-out, heard-from-every
room-in-the-house louder than hell, and has been so since the day it
darkened my doorway--with the RF deck at idle.
