which the diodes are mounted -- much like the transfer of sound from a
string bridge to the top plate of a violin.

I am sure Wayne has a lot on his "rainy day" list.
And as the old song goes, "It never rains in California... but man it

The last time this came up, Wayne theorized that it might be the
sound of slight mechanical adjustments in the relays as power is
redistributed. They aren't being switched, but the coil voltages may be
changing slightly, inducing an audible modulation in the electrically
shiftable parts
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 eve

It would probably only be audible to the guy who could read Heisenberg
uncertainty on his voltmeter.

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.

Steve,
Except for the noise my straight key makes, I've never noticed any
noise from the KX3...

For example - when I stick my headphones on with my FT-857D it still clicks
between RX and TX. It makes it impossible to have quiet, non-bothersome
