[Elecraft] CW transmitting - any clicks?

[Graham Smith]

My K2 emits a very faint "tick" sound at the end of each dot and dash - I
can hear it if I put my ear near the back of the K3.
This happens using the internal keyer and a straight key, although it's
extremely hard to hear using a straight key as the mechanical sound from the
key itself masks it even when releasing it very gently.
It's not coming from the speaker.

Have other people noticed this?
I wonder what is causing it?  It does this even with the power level set to
zero and I have VOX+QSK set.

Steve,

The K2, K1, KX1 and K3 all have electronic Transmit/Receive switching, and I
would expect the KX3 will as well, so there will be no relay clicking noise.
