Yes, I find that the number of decodes is less this afternoon than last
evening. Yes, we've worked twice, last evening and again this
afternoon. Glad you have things going. I'm running my K3S at about
30 watts driving the KPA500 to 450 watts. The antenna is a 4 ele
HyGain at 55 ft fed with 1/2" Andrew hard line, except for the 10'
section around the rotating sleeve and to the feed point on the antenna
which is RG-213.
Confusing to many is the fact there are three different places which
affect the transmit audio going to the radio. The Windows Sound mixer,
here I have the "speaker" level set at 35%. Then the PWR slider on the
WSJT panel, which is actually audio level and not power which is at
about 50%. And then the Line Gain which in Data A mode is controlled
by the knob on the radio marked MIC which is at 30. But when comes up
on the display as LINE xx. Depending various items in the system, these
number may be different than yours. At the same time, I always
suggest a value about "mid way". Once you get them all nailed down,
then go to WSJT F2 menu, AUDIO tab, and set Remember Power Per Band for
TRANSMIT and TUNE. Check the boxes. That way you will have less to
fiddle with when leaving or coming back to WSJT.
Thanks for the contact.

Hi Bob,
I don't recall if it was from the WSJT-X
online help page or advice from a K3s user
but I had my WSJT-X power bar around 80%
and in the sound manager, both playback &
recording levels are around 52%.
With that, the line level value in the K3s
was around 7. After the suggestions
earlier I moved it to line level 8 and all
5 bars were solid. To the good, I was not
having that issue of false transmit and
needing to jog the power to get output.
I'm willing to follow suggestions and see
how it goes so I moved the power slider to
roughly 1/2 way which then required me to
adjust the line level value on the K3s to
26. Checking the levels in sound manager,
they remain at 52.
At this point the meteors seem to be
hitting less, the shower may well be over.
I've only made one Q in the last 20
minutes and that was an E contact from 163
miles away. I'm not reading decodes so the
band is quiet but all seems well, I am
seeing proper output. 40W drive is putting
out 900W on 6M with every transmission.
Fingers crossed these changes are the
solution. I hope these posts help others
in the future, and thanks for the reply.
Oh... How timely, you & I just started a
MSK144 Q & at 807 miles. Things are still
going! :)

Do understand in the K3 & K3S operation the actual output power is
controlled by the PWR setting on the radio. The PWR setting on the
WSJT-X screen is actually audio level. This should be adjusted
about mid scale for both TUNE and TRANSMIT. The radio Line Gain will
then allow you to adjust the udio level such that you have 4 bars
solid on the ALC scale. The 5th bar should be flickering.

Don & Jim,
Yes, I do have it set for the DATA A. The
bars were with the 5th flickering.
I just bumped the line from 7, to 8. Now
they are solid bars, no flicker. It does
seem to be OK at this moment and perhaps
that is what I needed to do. It was
intermittent before so will have to wait
and see.
I'll come back if this does not resolve
the issue. Thanks for the input.

Gary,
Are you working in DATA A mode, and driving the audio to 4 bars
solid with the 5th bar flickering on the ALC meter?
That is the No ALC point for the K3/K3S/KX2/KX3. The lower bars
are there to give you a guide to adjust the audio.
So the common internet advice not to drive into ALC is being
observed - it is just that to point where that occurs is at a full
5th bar on the ALC meter.
Moving the power knob "reactivates" the power control circuits, but
if you do not have enough audio, the power will not be steady - the
radio will "power hunt"

Last night while using the K3s and WSJT-X
on meteor Scatter in the MSK144 mode I was
making numerous contacts. I stopped for
awhile and returned, this time noticing I
was not putting out any output from the
amp.
The rig went into the transmit state, and
the relay engaged on the amp. There was a
small grid current on the amp as one gets
with key down and no transmitted signal.
When I eventually moved the power control
on the K3s ever so slightly, it
transmitted properly. I had to do this
several times but did not notice it
before.
I re-loaded the factory settings with the
Elecraft Utility and the issue remains
albeit it is intermittent. Slightly moving
the power knob resolves the issue.
