Pete:
The first 4 bars on the K3 ALC are just an audio level indication [i.e.
VU meter]. ALC action starts at the 5th bar, which you want to be just
flickering. Unless you have 4 solid bars, the K3 will keep trying to
adjust the TX gain to achieve the selected output power and it may not
be able to get there with such low audio input, hence the "hunting."

I've recently started operating FT8, and on advice from other K3
users, have been adjusting the power slider in WSJT-X to a level just
short of or just into the first flickers of ALC. I did this because I
was advised that setting the slider for 4 or 5 bars of ALC generated
junk in the FT8 passband. I am running the K3 in Data A mode
Since I did this, I've noticed strange (to me, anyway) behavior from
my K3. When WSJT-X starts an FT8 transmit cycle, after I have just
switched to the current band or changed the power slider in WSJT-X or
the PWR control on my K-3, the K3's power output starts essentially at
zero and slowly ramps up through 1- 1 1/2 FT8 transmit cycles. Once
it reaches the expected level, subsequent transmissions stay at that
level.
I've been told (not by Elecraft) that this behavior is a result of the
K3's firmware "hunting" for the right power level, but such a slow and
repetitious behavior doesn't fit with the rest of what I've come to
expect from my K3. It doesn't happen on CW or SSB either. So what's
going on?
