No problems here. My K3/100 #0192 loaded with the latest FW switches on
without any bursts of noise. Just a few relay clicks and the radio comes to
life as one would expect.

Subject: [Elecraft] K3 - 2.73/1.98 Clicks on Power On
The power on rush of noise is almost earsplitting here in headset and
external speakers, K3 serial 509. It lasts for about a quarter of a
second.
If I had the volume turned up it could cause damage to a speaker or my
ears,
it is that loud. For this reason alone it should be a high priority fix.
Perhaps just blank the receiver in the turn on sequence for enough time to
cover the transient.
It has existed over the last several firmware updates. I notice that it is
worse when the bandwidth is set wider such as 2.7 KHz SSB mode. It does
not
matter if a signal is present or not. I have high background noise level
here (S-7) so I expect that might be equivalent to having a signal
present.
When set for CW at 400 Hz the momentary noise is there but much-much
subdued
and not objectionable at all so CW operators may not notice the effect.
The
effect is there in SSB/Data/CW modes. I don't hear it in AM/13KHz.
