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?
