I agree with Bill. Every instance of "fan noise" that I recall being posted here ended up being assembly error (or more properly, oversight). And since you say that they CAN be quieted down with adjustment, I would suggestion checking for a wire touching the blades when they spin. Loosening the nuts may be providing just enough clearance so that the obstruction is no longer contacted. My experience (with a pair of K3's) is that the fans should be entirely whisper quiet.
Good luck! de Doug KR2Q _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
