If you have an older K3 there was a problem with them generating a spur. I
had the problem when a friend reported hearing me on a 2nd freq.I'm guessing
nobody still has an older K3 though with this problem.
We have determined that a small number of K3/100s and KPA3s left the factory

I've seen a K3 generate spurs when the power supply was overloaded, and
went into current limit.

I was watching 6m yesterday and noticed several spurs. They were spaced 39kHz
apart. Amplitude dropped but didn't disappear when switched to dummy load.
I have the K3 with new synthesizer boards. Just wondering if anyone else seeing
something similar. IOW is it something in the K3 or external?
