[Elecraft] K3: The Audio pop noise when K3 rig is turned ON. Solution?

[Mark Murray]

In the older K3 rigs:  What was the old 'solution' to eliminate the initial
audio 'pop' when the K3 is turned 'ON' ??

Background:  Back in 2009-2010 there was a short list-serve exchange on the
topic of the audio 'pop' noise heard when some of the K3 rigs were initially
turned on.  The noise was described as a simultaneous "double pop" of medium
volume heard in the speaker and lasting only a split second, with
practically no spacing between the two.  Heard in the speaker regardless of
the volume control setting. A noise similar to the radio noise of two
far-away lightning strikes.  Searching those old 2010 exchanges did not turn
up a 'solution'.  Likewise with the Elecraft site.  With that, then, it's
easy to 'assume' there is no real issue with the noises, no harm to be
expected, no real problem here, let the rig greet the op and say 'hello' in
its own way, and let it be.  But with masterful electronics, I don't like to
assume anything.  Did the pops disappear with later production units.  If
so, was there a home solution, as well?
