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.

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.
I have just tried this several times since installing MCU 2.73 and have
noticed some minor clicks in the outboard speaker but none when using
headphones. I really had not noticed this until it was mentioned here. My
Orion does the same thing though.

This is just a case of hearing the electronics become active. Unlike my

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 just reloaded firmware suite 2.67/1.96 and the problem exists there as
well. I guess I have just never turned ON the K3 with a good signal on
the VFO freq. One other thing I checked... with the AF Gain at minimum,
the artifact is not there, but with even the smallest amount of AF Gain,

I agree. I've noticed the same effect since purchase and it has not changed
in the least with any F/W upgrades.

Hi all,
Same here as Stewart and I replied already on an older tread on the same
subject. Meanwhile I found out the following and forwarded that info,
including an MP3 recording of the various settings, to Lyle of the Elecraft
team, who responded to my post.
The procedure to reproduce this is

My K3/100 has always clicked when it powered on. I thought it was just the
relays resetting or some initialization. Is the click on the speaker or in the
relays on the board(s) ?
Upon boot up the K3 also keys the amp for a split second too.

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.
We are looking closely at this symptom now and are working on a firmware
revision to mitigate it.

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.
Hi Mike,
It is. This is something that doesn't show up all the time so we were
not aware of it until it was noted here on the list recently.
We're adding an additional power on mute time delay to the firmware
right now.
