I'm even getting a very loud blast of noise when I power on on 80m band
with no signal. I'm pretty sure the problem is that the AGC hasn't
activated yet. If I turn the AGC off, I get the same level of noise as
the blast on power-on.
This started with one of the recent firmware updates.

I just tried power Off/On using earphones with speakers muted.I hear the
same loud artifact with the earphones and through the speakers when
there is a signal on the vfo freq.

I notice the same thing, but only when there is a signal on the
frequency tuned in on the K3 when power is turned ON. AF gain set at
about 9 o'clock, CONFIG:AF GAIN HI. With no signal on the tuned
frequency, the loud audio does not happen. I did not notice this on
previous firmware versions. Later this morning I'll reinstall previous
firmware and double check.

Hi,
Since installing MCU 2.73. I have noticed that power on is
accompanied by a number of loud, rather unpleasant clicks/clunks
from the speaker.
